Euphoria

From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/Euphoria
Playing can induce an intense state of happiness and contentment, like this girl playing in the snow.

Euphoria (/juːˈfɔːriə/ yoo-FOR-ee-ə) is the experience (or affect) of pleasure or excitement and intense feelings of well-being and happiness. Certain natural rewards and social activities, such as aerobic exercise, laughter, listening to or making music and dancing, can induce a state of euphoria. Euphoria is also a symptom of certain neurological or neuropsychiatric disorders, such as mania. Romantic love and components of the human sexual response cycle are also associated with the induction of euphoria. Certain drugs, many of which are addictive, can cause euphoria, which at least partially motivates their recreational use.

Hedonic hotspots – i.e., the pleasure centers of the brain – are functionally linked. Activation of one hotspot results in the recruitment of the others. Inhibition of one hotspot results in the blunting of the effects of activating another hotspot. Therefore, the simultaneous activation of every hedonic hotspot within the reward system is believed to be necessary for generating the sensation of an intense euphoria.

History

The word "euphoria" is derived from the Ancient Greek terms εὐφορία: εὖ eu meaning "well" and φέρω pherō meaning "to bear". It is semantically opposite to dysphoria.

A 1706 English dictionary defines euphoria as "the well bearing of the Operation of a Medicine, i.e., when the patient finds himself eas'd or reliev'd by it".

During the 1860s, the English physician Thomas Laycock described euphoria as the feeling of bodily well-being and hopefulness; he noted its misplaced presentation in the final stage of some terminal illnesses and attributed such euphoria to neurological dysfunction. Sigmund Freud's 1884 monograph Über Coca described (his own) consumption of cocaine producing "the normal euphoria of a healthy person", while about 1890 the German neuropsychiatrist Carl Wernicke lectured about the "abnormal euphoria" in patients with mania.

A 1903 article in The Boston Daily Globe refers to euphoria as "pleasant excitement" and "the sense of ease and well-being". In 1920 Popular Science magazine described euphoria as "a high sounding name" meaning "feeling fit": normally making life worth living, motivating drug use, and ill formed in certain mental illnesses. Robert S. Woodworth's 1921 textbook Psychology: A study of mental life, describes euphoria as an organic state which is the opposite of fatigue, and "means about the same as feeling good."

In 1940, The Journal of Psychology defined euphoria as a "state of general well being ... and pleasantly toned feeling." A decade later, finding ordinary feelings of well being difficult to evaluate, American addiction researcher Harris Isbell redefined euphoria as behavioral changes and objective signs typical of morphine. However, in 1957 British pharmacologist D. A. Cahal did not regard opioid euphoria as medically undesirable but an effect which "enhance[s] the value of a major analgesic." The 1977 edition of A Concise Encyclopaedia of Psychiatry called euphoria "a mood of contentment and well-being," with pathologic associations when used in a psychiatric context. As a sign of cerebral disease, it was described as bland and out of context, representing an inability to experience negative emotion.

In the 21st century, euphoria is generally defined as a state of great happiness, well-being and excitement, which may be normal, or abnormal and inappropriate when associated with psychoactive drugs, manic states, or brain disease or injury.

Neuropsychology

Hedonic hotspots are functionally interrelated neural substrates/structures that (intrinsically or extrinsically) generate the feelings of pleasure. Activation of one hedonic hotspot involves the stimulation of the others. Inhibition of one hedonic hotspot blunts the activation the other ones. Therefore, the simultaneous activation of every hedonic hotspot within the reward system is probably necessary for generating the sensation of euphoria.

Types

Many different types of stimuli can induce euphoria, including psychoactive drugs, natural rewards, and social activities. Affective disorders such as unipolar mania or bipolar disorder can involve euphoria as a symptom.

Exercise-induced

Continuous exercise can produce a transient state of euphoria – an emotional state involving the experience of pleasure and feelings of profound contentment, elation, and well-being – which is colloquially known as a "runner's high" in distance running or a "rower's high" in rowing.

Music-induced

Euphoria can occur as a result of dancing to music, music-making, and listening to emotionally arousing music. Neuroimaging studies have demonstrated that the reward system plays a central role in mediating music-induced pleasure. Pleasurable emotionally arousing music strongly increases dopamine neurotransmission in the dopaminergic pathways that project to the striatum (i.e., the mesolimbic pathway and nigrostriatal pathway). Approximately 5% of the population experiences a phenomenon termed "musical anhedonia", in which individuals do not experience pleasure from listening to emotionally arousing music despite having the ability to perceive the intended emotion that is conveyed in passages of music.

A clinical study from January 2019 that assessed the effect of a dopamine precursor (levodopa), dopamine antagonist (risperidone), and a placebo on reward responses to music – including the degree of pleasure experienced during musical chills, as measured by changes in electrodermal activity as well as subjective ratings – found that the manipulation of dopamine neurotransmission bidirectionally regulates pleasure cognition (specifically, the hedonic impact of music) in human subjects. This research suggests that increased dopamine neurotransmission acts as a sine qua non condition for pleasurable hedonic reactions to music in humans.

Sex-induced

The various stages of copulation may also be described as inducing euphoria in some people. Various analysts have described either the entire sexual act, the moments leading to orgasm, or the orgasm itself as the pinnacle of human pleasure or euphoria.

Drug-induced

A large dose of methamphetamine causes a drug-induced euphoria.

A euphoriant is a type of psychoactive drug which tends to induce euphoria. Most euphoriants are addictive drugs due to their reinforcing properties and ability to activate the brain's reward system.

Stimulants

Dopaminergic stimulants like amphetamine, methamphetamine, cocaine, MDMA, and methylphenidate are euphoriants. Nicotine is a parasympathetic stimulant that acts as a mild euphoriant in some people. Xanthines such as caffeine and theobromine may also be considered mild euphoriants by some.

Chewing areca nut (seeds from the Areca catechu palm) with slaked lime (calcium hydroxide) – a common practice in South- and Southeast Asia – produces stimulant effects and euphoria. The major psychoactive ingredients – arecoline (a muscarinic receptor partial agonist) and arecaidine (a GABA reuptake inhibitor) – are responsible for the euphoric effect.

Depressants

Certain depressants can produce euphoria; some of those drugs in this class include alcohol in moderate doses, γ-hydroxybutyric acid (GHB), and ketamine.

Some barbiturates and benzodiazepines may cause euphoria. Euphoriant effects are determined by the drug's speed of onset, increasing dose, and with intravenous administration. Barbiturates more likely to cause euphoria include amobarbital, secobarbital and pentobarbital. Benzodiazepines more likely to cause euphoria are flunitrazepam, alprazolam and clonazepam. Benzodiazepines also tend to enhance opioid-induced euphoria.

Pregabalin induces dose-dependent euphoria. Occurring in a small percentage of individuals at recommended doses, euphoria is increasingly frequent at supratherapeutic doses (or with intravenous- or nasal administration). At doses five times the maximum recommended, intense euphoria is reported. Another GABA analogue, gabapentin, may induce euphoria. Characterized as opioid-like but less intense, it may occur at supratherapeutic doses, or in combination with other drugs, such as opioids or alcohol. Ethosuximide and perampanel can also produce euphoria at therapeutic doses.

Opioids

μ-Opioid receptor agonists are a set of euphoriants that include drugs such as heroin, morphine, codeine, oxycodone, and fentanyl. By contrast, κ-opioid receptor agonists, like the endogenous neuropeptide dynorphin, are known to cause dysphoria, a mood state opposite to euphoria that involves feelings of profound discontent.

Cannabinoids

Cannabinoid receptor 1 agonists are a group of euphoriants that includes certain plant-based cannabinoids (e.g., THC from the cannabis plant), endogenous cannabinoids (e.g., anandamide), and synthetic cannabinoids.

Inhalants

Certain gases, like nitrous oxide (N2O, aka "laughing gas"), can induce euphoria when inhaled.

Psychedelics

Traditional psychedelic drugs, such as LSD and psilocybin are capable of inducing euphoria despite lacking addictive qualities. The Global Drug Survey has revealed that out of 22,000 participant reports, MDMA, LSD, and psilocybin mushrooms were ranked most positively on the Net Pleasure Index of all recreational drugs included in the study.

Glucocorticoids

Acute exogenous glucocorticoid administration is known to produce euphoria, but this effect is not observed with long-term exposure.

List of euphoriants by mechanism of action

The following is a full list of euphoriant or rewarding/reinforcing drugs:

Fasting–induced

Fasting has been associated with improved mood, well-being, and sometimes euphoria. Various mechanisms have been proposed and possible applications in treating depression considered.

Neuropsychiatric

Mania

Euphoria is also strongly associated with both hypomania and mania, mental states characterized by a pathological heightening of mood, which may be either euphoric or irritable, in addition to other symptoms, such as pressured speech, flight of ideas, and grandiosity.

Although hypomania and mania are syndromes with multiple etiologies (that is, ones that may arise from any number of conditions), they are most commonly seen in bipolar disorder, a psychiatric illness characterized by alternating periods of mania and depression.

Epilepsy

Euphoria may occur during auras of seizures typically originating in the temporal lobe, but affecting the anterior insular cortex. This euphoria is symptomatic of a rare syndrome called ecstatic seizures, often also involving mystical experiences. Euphoria (or more commonly dysphoria) may also occur in periods between epileptic seizures. This condition, interictal dysphoric disorder, is considered an atypical affective disorder. Persons who experience feelings of depression or anxiety between or before seizures occasionally experience euphoria afterwards.

Migraine

Some persons experience euphoria in the prodrome – hours to days before the onset – of a migraine headache. Similarly, a euphoric state occurs in some persons following the migraine episode.

Multiple sclerosis

Euphoria sometimes occurs in persons with multiple sclerosis as the illness progresses. This euphoria is part of a syndrome originally called euphoria sclerotica, which typically includes disinhibition and other symptoms of cognitive and behavioral dysfunction.

Gender euphoria

Gender euphoria is satisfaction or enjoyment felt by a person due to consistency between their gender identity and gendered features associated with a gender different to the sex they were assigned at birth. It is considered to be the positive counterpart of gender dysphoria. Related euphorias have also been recorded in studies of alignments between sexual identity and social recognition such as support in schools for lesbian and gay people, and experiences of intersex variation and their diagnoses such as receiving a diagnosis of congenital adrenal hyperplasia which explained physical differences for example.

East Asian studies

From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/East_Asian_studies

East Asian studies
is a distinct multidisciplinary field of scholarly enquiry and education that promotes a broad humanistic understanding of East Asia past and present. The field includes the study of the region's culture, written language, history and political institutions. East Asian studies is located within the broader field of Asian studies and is also interdisciplinary in character, incorporating elements of the social sciences (anthropology, economics, sociology, politics etc.) and humanities (literature, history, art, film, music, etc.), among others. The field encourages scholars from diverse disciplines to exchanges ideas on scholarship as it relates to the East Asian experience and the experience of East Asia in the world. In addition, the field encourages scholars to educate others to have a deeper understanding of and appreciation and respect for, all that is East Asia and, therefore, to promote peaceful human integration worldwide.

At universities throughout North America and the Western world, the study of East Asian humanities is traditionally housed in EALC (East Asian Languages and Civilizations or Cultures) departments, which run majors in Chinese and Japanese language and literature and sometimes Korean language and literature. East Asian studies programs, on the other hand, are typically interdisciplinary centers that bring together literary scholars, historians, anthropologists, sociologists, political scientists, etc. from their various departments and schools to promote instructional programs, conferences and lecture series of common interest. East Asian studies centers also often run interdisciplinary undergraduate and master's degree programs in East Asian studies.

Subfields

Sinology

The sub-field dedicated to China, Chinese history, Chinese culture, Chinese literature, and the Chinese language. In the context of the Republic of China also specified as Taiwan studies (Academia Sinica).

Japanology

The sub-field dedicated to Japan, Japanese culture, Japanese history, Japanese literature, and the Japanese language. The foundation of the Asiatic Society of Japan at Yokohama in 1872 by men such as Ernest Satow and Frederick Victor Dickins was an important event in the development of Japanese studies as an academic discipline.

Koreanology

The sub-field dedicated to Korea, Korean culture, Korean history, Korean literature, and the Korean language. The term Korean studies first began to be used in the 1940s, but did not attain widespread currency until South Korea rose to economic prominence in the 1970s. In 1991, the South Korean government established the Korea Foundation to promote Korean studies.

Mongolian studies

The sub-field dedicated to Mongolia, Mongolian culture, Mongolian literature and the Mongolian language. Mongolian studies are also presented as a sub-field of the study of Inner Asia (as opposed to East Asia). The American Center for Mongolian Studies was founded in 2002.

Orient

In addition to the above, studies about the history of the Orient have mainly developed in Japan. Orient means areas in North Africa, Eurasia except Europe and islands around them because of chaos due to studies about the history of Greater China and Korea under the Tokugawa shogunate before 1868 and those about the Eastern world from the establishment of European-style high-educational institutions after that year.

The notion about Oriental history that was made between 1868 and 1945 did not spread on other East Asian areas including Korea as the colony of Japan. There have been some Japanese notable historians about Oriental history but they are less famous in other countries.

History

In universities across the United States, as part of the opposition to the Vietnam War in the 1960s, younger faculty and graduate students criticized the field for complicity in what they saw as American imperialism. In particular, the Committee of Concerned Asian Scholars debated and published alternative approaches not centered in the United States or funded, as many American programs were, by the American government or major foundations. They charged that Japan was held up as a model of non-revolutionary modernization and the field focused on modernization theory in order to fend off revolution.

In the following decades, many critics were inspired by Edward Said's 1978 book Orientalism, while others, writing from the point of view of the quantitative or theoretical social sciences, saw area studies in general and East Asian studies in particular, as amorphous and lacking in rigor.

Critiques were also mounted from other points in the political spectrum. Ramon H. Myers and Thomas A. Metzger, two scholars based at the generally conservative Hoover Institution, charged that "the 'revolution' paradigm increasingly overshadowed the 'modernization' paradigm" and "this fallacy has become integral to much of the writing on modern Chinese history", discrediting or ignoring other factors in the history of modern China.

In Europe, notable scholars of East Asian studies have long occupied professorships at prominent universities in the United Kingdom, Germany, the Netherlands, France and Italy, while recent publications also suggest that the "Nordic countries offer some unique contributions in the field of East Asian studies."

Journals

Some journals also cover other regions of Asia in addition to East Asia.

Greater Iran

From Wikipedia, the free encyclopedia
The Sasanian Empire at its greatest extent c. 620, under Khosrow II

Greater Iran or Greater Persia (Persian: ایران بزرگ Irān-e Bozorg), also called the Iranosphere or the Persosphere, is an expression that denotes a wide socio-cultural region comprising parts of West Asia, the Caucasus, Central Asia, South Asia, and East Asia (specifically the Tarim Basin)—all of which have been affected, to some degree, by the Iranian peoples and the Iranian languages.

It is defined by having long been ruled by the dynasties of various Iranian empires, under whom the local populaces gradually incorporated some degree of Iranian influence into their cultural and/or linguistic traditions; or alternatively as where a considerable number of Iranians settled to still maintain communities who patronize their respective cultures, geographically corresponding to the areas surrounding the Iranian plateau. It is referred to as the "Iranian Cultural Continent" by Encyclopædia Iranica.

Throughout the 16th–19th centuries, Iran lost many of the territories that had been conquered under the Safavids and Qajars.

The Ottoman–Iranian Wars resulted in the loss of present-day Iraq to the Ottoman Empire, as outlined in the Treaty of Amasya in 1555 and the Treaty of Zuhab in 1639.

Simultaneously, the Russo-Iranian Wars resulted in the loss of the Caucasus to the Russian Empire: the Treaty of Gulistan in 1813 saw Iran cede present-day Dagestan, Georgia, and most of Azerbaijan; the Treaty of Turkmenchay in 1828 saw Iran cede present-day Armenia, the remainder of Azerbaijan, and Iğdır, setting the northern boundary along the Aras River.

Parts of Afghanistan were lost to the British Empire through the Treaty of Paris in 1857 and the McMahon Arbitration in 1905.

Etymology

The name "Iran", meaning "land of the Aryans", is the New Persian continuation of the old genitive plural aryānām (proto-Iranian, meaning "of the Aryans"), first attested in the Avesta as airyānąm (the text of which is composed in Avestan, an old Iranian language spoken in northeastern Greater Iran, or in what are now Afghanistan, Uzbekistan, Turkmenistan and Tajikistan).

The proto-Iranian term aryānām is present in the term Airyana Vaēǰah, the homeland of Zoroaster and Zoroastrianism, near the provinces of Sogdiana, Margiana, Bactria, etc., listed in the first chapter of the Vidēvdād. The Avestan evidence is confirmed by Greek sources: Arianē is spoken of as being between Persia and the Indian subcontinent.

However, this is a Greek pronunciation of the name Haroyum/Haraiva (Herat), which the Greeks called 'Aria' (a land listed separately from the homeland of the Aryans).

While up until the end of the Parthian period in the 3rd century CE, the idea of "Irān" had an ethnic, linguistic, and religious value, it did not yet have a political import. The idea of an "Iranian" empire or kingdom in a political sense is a purely Sasanian one. It was the result of a convergence of interests between the new dynasty and the Zoroastrian clergy, as we can deduce from the available evidence.

This convergence gave rise to the idea of an Ērān-šahr "Kingdom of the Iranians", which was "ēr" (Middle Persian equivalent of Old Persian "ariya" and Avestan "airya").

Definition

Richard Nelson Frye defines Greater Iran as including "much of the Caucasus, Iraq, Afghanistan, Pakistan and Central Asia, with cultural influences extending to China and western India."

According to him, "Iran means all lands and peoples where Iranian languages were and are spoken, and where in the past, multi-faceted Iranian cultures existed."

Richard Foltz notes that while "A general assumption is often made that the various Iranian peoples of 'greater Iran'—a cultural area that stretched from Mesopotamia and the Caucasus into Khwarizm, Transoxiana, Bactria, and the Pamirs and included Persians, Medes, Parthians and Sogdians among others—were all 'Zoroastrians' in pre-Islamic times... This view, even though common among serious scholars, is almost certainly overstated." He argues that "While the various Iranian peoples did indeed share a common pantheon and pool of religious myths and symbols, in actuality a variety of deities were worshipped—particularly Mitra, the god of covenants, and Anahita, the goddess of the waters, but also many others—depending on the time, place, and particular group concerned".

To the Ancient Greeks, Greater Iran ended at the Indus River located in Pakistan.

According to J. P. Mallory and Douglas Q. Adams most of Western greater Iran spoke Southwestern Iranian languages in the Achaemenid era while the Eastern territory spoke Eastern Iranian languages related to Avestan.

George Lane also states that after the dissolution of the Mongol Empire, the Ilkhanids became rulers of greater Iran and Uljaytu, according to Judith G. Kolbas, was the ruler of this expanse between 1304 and 1317 A.D.

Primary sources, including Timurid historian Mir Khwand, define Iranshahr (Greater Iran) as extending from the Euphrates to the Oxus

The Cambridge History of Iran takes a geographical approach in referring to the "historical and cultural" entity of "Greater Iran" as "areas of Iran, parts of Afghanistan, Chinese and Soviet Central Asia".

Background

An Ashrafi Coin of Nader Shah
An Ashrafi Coin of Nader Shah (r. 1736–1747), reverse: "Coined on gold the word of kingdom in the world, Nader of Greater Iran and the world-conqueror king."

Greater Iran is called Iranzamin (ایران‌زمین) which means "Iranland" or "The Land of Iran". Iranzamin was in the mythical times as opposed to the Turanzamin, "The Land of Turan", which was located in the upper part of Central Asia.

With Imperial Russia continuously advancing south in the course of two wars against Persia, and the treaties of Turkmenchay and Gulistan in the western frontiers, plus the unexpected death of Abbas Mirza in 1833, and the murdering of Persia's Grand Vizier (Mirza AbolQasem Qa'im Maqām), many Central Asian khanates began losing hope for any support from Persia against the Tsarist armies. The Russian armies occupied the Aral coast in 1849, Tashkent in 1864, Bukhara in 1867, Samarkand in 1868, and Khiva and Amudarya in 1873.

"Many Iranians consider their natural sphere of influence to extend beyond Iran's present borders. After all, Iran was once much larger. Portuguese forces seized islands and ports in the 16th and 17th centuries. In the 19th century, the Russian Empire wrested from Tehran's control what is today Armenia, Republic of Azerbaijan, and part of Georgia. Iranian elementary school texts teach about the Iranian roots not only of cities like Baku, but also cities further north like Derbent in southern Russia. The Shah lost much of his claim to western Afghanistan following the Anglo-Iranian war of 1856-1857. Only in 1970 did a UN sponsored consultation end Iranian claims to suzerainty over the Persian Gulf island nation of Bahrain. In centuries past, Iranian rule once stretched westward into modern Iraq and beyond. When the western world complains of Iranian interference beyond its borders, the Iranian government often convinced itself that it is merely exerting its influence in lands that were once its own. Simultaneously, Iran's losses at the hands of outside powers have contributed to a sense of grievance that continues to the present day." -Patrick Clawson of the Washington Institute for Near East Policy
"Iran today is just a rump of what it once was. At its height, Iranian rulers controlled Iraq, Afghanistan, Western Pakistan, much of Central Asia, and the Caucasus. Many Iranians today consider these areas part of a greater Iranian sphere of influence." - Patrick Clawson
"Since the days of the Achaemenids, the Iranians had the protection of geography. But high mountains and the vast emptiness of the Iranian plateau were no longer enough to shield Iran from the Russian army or British navy. Both literally, and figuratively, Iran shrank. At the beginning of the nineteenth century, Azerbaijan, Armenia, and Afghanistan were Iranian, but by the end of the century, all this territory had been lost as a result of European military action."

Regions

In the 8th century, Iran was conquered by the Arab Abbassids who ruled from Baghdad. The territory of Iran at that time was composed of two portions: Persian Iraq (western portion) and Khorasan (eastern portion). The dividing region was mostly the cities of Gurgan and Damaghan. The Ghaznavids, Seljuqs and Timurids divided their empires into Iraqi and Khorasani regions. This point can be observed in many books such as Abul Fazl Bayhqi's "Tārīkhi Baïhaqī", Al-Ghazali's Faza'ilul al-anam min rasa'ili hujjat al-Islam and other books. Transoxiana and Chorasmia were mostly included in the Khorasanian region.

Caucasus

North Caucasus

Sassanian fortress in Derbent, Dagestan. Now inscribed on Russia's UNESCO world heritage list since 2003.

Dagestan remains the bastion of Persian culture in the North Caucasus with fine examples of Iranian architecture like the Sassanid citadel in Derbent, the strong influence of Persian cuisine, and common Persian names amongst the ethnic peoples of Dagestan. The ethnic Persian population of the North Caucasus, the Tats, remain, despite strong assimilation over the years, still visible in several North Caucasian cities. Even today, after decades of partition, some of these regions retain Iranian influences, as seen in their old beliefs, traditions and customs (e.g. Norouz).

South Caucasus

According to Tadeusz Swietochowski, the territories of Iran and the republic of Azerbaijan usually shared the same history from the time of ancient Media (ninth to seventh centuries b.c.) and the Persian Empire (sixth to fourth centuries b.c.).

Intimately and inseparably intertwined histories for millennia, Iran irrevocably lost the territory that is nowadays Azerbaijan in the course of the 19th century. With the Treaty of Gulistan of 1813 following the Russo-Persian War (1804–1813) Iran had to cede eastern Georgia, its possessions in the North Caucasus and many of those in what is today the Azerbaijan Republic, which included the khanates of Baku, Shirvan, Karabakh, Ganja, Shaki, Quba, Derbent, and parts of Talysh. These Khanates comprise most of what is today the Republic of Azerbaijan and Dagestan in Southern Russia. In the Treaty of Turkmenchay of 1828 following the Russo-Persian War (1826–1828), the result was even more disastrous, and resulted in Iran being forced to cede the remainder of the Talysh Khanate, the khanates of Nakhichevan and Erivan, and the Mughan region to Russia. All these territories together, lost in 1813 and 1828 combined, constitute all of the modern-day Republic of Azerbaijan, Armenia, and southern Dagestan. The area to the North of the river Aras, among which the territory of the contemporary republic of Azerbaijan were Iranian territory until they were occupied by Russia in the course of the 19th century.

Many localities in this region bear Persian names or names derived from Iranian languages and Azerbaijan remains by far Iran's closest cultural, religious, ethnic, and historical neighbor. Azerbaijanis are by far the second-largest ethnicity in Iran, and comprise the largest community of ethnic Azerbaijanis in the world, vastly outnumbering the number in the Republic of Azerbaijan. Both nations are the only officially Shia majority in the world, with adherents of the religion comprising an absolute majority in both nations. The people of nowadays Iran and Azerbaijan were converted to Shiism during exactly the same time in history. Furthermore, the name of "Azerbaijan" is derived through the name of the Persian satrap which ruled the contemporary region of Iranian Azerbaijan and minor parts of the Republic of Azerbaijan in ancient times.

Khwarazm is one of the regions of Iran-zameen, and is the home of the ancient Iranians, Airyanem Vaejah, according to the ancient book of the Avesta. Modern scholars believe Khwarazm to be what ancient Avestic texts refer to as "Ariyaneh Waeje" or Iran vij. Iranovich These sources claim that Urgandj, which was the capital of ancient Khwarazm for many years, was actually "Ourva": the eighth land of Ahura Mazda mentioned in the Pahlavi text of Vendidad. Others such as University of Hawaii historian Elton L. Daniel believe Khwarazm to be the "most likely locale" corresponding to the original home of the Avestan people, while Dehkhoda calls Khwarazm "the cradle of the Aryan people" (مهد قوم آریا). Today Khwarazm is split between several central Asian republics.

Superimposed on and overlapping with Chorasmia was Khorasan which roughly covered nearly the same geographical areas in Central Asia (starting from Semnan eastward through northern Afghanistan roughly until the foothills of Pamir, ancient Mount Imeon). Current day provinces such as Sanjan in Turkmenia, Razavi Khorasan Province, North Khorasan Province, and Southern Khorasan Province in Iran are all remnants of the old Khorasan. Until the 13th century and the devastating Mongol invasion of the region, Khorasan was considered the cultural capital of Greater Iran.

West Asia

Bahrain

Buyid Dynasty

From the 6th century BC to the 3rd century BC, Bahrain was a prominent part of the Persian Empire under the Achaemenid dynasty. It was referred to by the Greeks as "Tylos", the centre of pearl trading, when Nearchus discovered it while serving under Alexander the Great. From the 3rd century BC to the arrival of Islam in the 7th century AD, the island was controlled by two other Iranian dynasties, the Parthians and the Sassanids.

In the 3rd century AD, the Sassanids succeeded the Parthians and controlled the area for four centuries until the Arab conquest. Ardashir, the first ruler of the Iranian Sassanid dynasty marched to Oman and Bahrain and defeated Sanatruq (or Satiran), probably the Parthian governor of Bahrain. He appointed his son Shapur I as governor. Shapur constructed a new city there and named it Batan Ardashir after his father. At this time, it incorporated the southern Sassanid province covering the Persian Gulf's southern shore plus the archipelago of Bahrain. The southern province of the Sassanids was subdivided into three districts; Haggar (now al-Hafuf province, Saudi Arabia), Batan Ardashir (now al-Qatif province, Saudi Arabia), and Mishmahig (now Bahrain Island) (In Middle-Persian/Pahlavi it means "ewe-fish").

Ghaznavids at their greatest extent

By about 130 BC, the Parthian dynasty brought the Persian Gulf under their control and extended their influence as far as Oman. Because they needed to control the Persian Gulf trade route, the Parthians established garrisons along the southern coast of the Persian Gulf. through warfare and economic distress, been reduced to only 60. The influence of Iran was further undermined at the end of the 18th century when the ideological power struggle between the Akhbari-Usuli strands culminated in victory for the Usulis in Bahrain.

An Afghan uprising led by Hotakis of Kandahar at the beginning of the 18th century resulted in the near-collapse of the Safavid state. In the resultant power vacuum, Oman invaded Bahrain in 1717, ending over one hundred years of Persian hegemony in Bahrain. The Omani invasion began a period of political instability and a quick succession of outside rulers took power with consequent destruction. According to a contemporary account by theologian, Sheikh Yusuf Al Bahrani, in an unsuccessful attempt by the Persians and their Bedouin allies to take back Bahrain from the Kharijite Omanis, much of the country was burnt to the ground. Bahrain was eventually sold back to the Persians by the Omanis, but the weakness of the Safavid empire saw Huwala tribes seize control.

The Safavid Empire under Shah Abbas the Great

In 1730, the new Shah of Persia, Nadir Shah, sought to re-assert Persian sovereignty in Bahrain. He ordered Latif Khan, the admiral of the Persian navy in the Persian Gulf, to prepare an invasion fleet in Bushehr.[citation needed] The Persians invaded in March or early April 1736 when the ruler of Bahrain, Shaikh Jubayr, was away on hajj. The invasion brought the island back under central rule and to challenge Oman in the Persian Gulf. He sought help from the British and Dutch, and he eventually recaptured Bahrain in 1736. During the Qajar era, Persian control over Bahrain waned and in 1753, Bahrain was occupied by the Sunni Persians of the Bushire-based Al Madhkur family, who ruled Bahrain in the name of Persia and paid allegiance to Karim Khan Zand.

Zands

During most of the second half of the eighteenth century, Bahrain was ruled by Nasr Al-Madhkur, the ruler of Bushehr. The Bani Utibah tribe from Zubarah exceeded in taking over Bahrain after war broke out in 1782. Persian attempts to reconquer the island in 1783 and in 1785 failed; the 1783 expedition was a joint Persian-Qawasim invasion force that never left Bushehr. The 1785 invasion fleet, composed of forces from Bushehr, Rig, and Shiraz was called off after the death of the ruler of Shiraz, Ali Murad Khan. Due to internal difficulties, the Persians could not attempt another invasion. In 1799, Bahrain came under threat from the expansionist policies of Sayyid Sultan, the Sultan of Oman, when he invaded the island under the pretext that Bahrain did not pay taxes owed. The Bani Utbah solicited the aid of Bushire to expel the Omanis on the condition that Bahrain would become a tributary state of Persia. In 1800, Sayyid Sultan invaded Bahrain again in retaliation and deployed a garrison at Arad Fort, in Muharraq island and had appointed his twelve-year-old son Salim, as Governor of the island.

Qajar dynasty at its greatest extent

Many names of villages in Bahrain are derived from the Persian language. These names were thought to have been as a result influences during the Safavid rule of Bahrain (1501–1722) and previous Persian rule. Village names such as Karbabad, Salmabad, Karzakan, Duraz, Barbar were originally derived from the Persian language, suggesting that Persians had a substantial effect on the island's history. The local Bahrani Arabic dialect has also borrowed many words from the Persian language. Bahrain's capital city, Manama is derived from two Persian words meaning 'I' and 'speech'.

In 1910, the Persian community funded and opened a private school, Al-Ittihad school, that taught Farsi amongst other subjects. According to the 1905 census, there were 1650 Bahraini citizens of Persian origin.

Historian Nasser Hussain says that many Iranians fled their native country in the early 20th century due to a law king Reza Shah issued which banned women from wearing the hijab, or because they feared for their lives after fighting the English or to find jobs. They were coming to Bahrain from Bushehr and the Fars province between 1920 and 1940. In the 1920s, local Persian merchants were prominently involved in the consolidation of Bahrain's first powerful lobby with connections to the municipality in an effort to contest the municipal legislation of British control.

Bahrain's local Persian community has heavily influenced the country's local food dishes. One of the most notable local delicacies of the people in Bahrain is mahyawa, which is consumed in Southern Iran as well. It is a watery, earth-brick-coloured sauce made from sardines, and consumed with bread or other food. Bahrain's Persians are also famous in Bahrain for bread-making. Another local delicacy is pishoo made from rose water (golab) and agar agar. Other food items consumed are similar to Persian cuisine.

Iraq

Throughout history, Iran always had strong cultural ties with the region of present-day Iraq. Mesopotamia is considered the cradle of civilization and the place where the first empires in history were established. These empires, namely the Sumerian, Akkadian, Babylonian, and Assyrian, dominated the ancient middle east for millennia, which explains the great influence of Mesopotamia on the Iranian culture and history, and it is also the reason why the later Iranian and Greek dynasties chose Mesopotamia to be the political center of their rule. For a period of around 500 years, what is now Iraq formed the core of Iran, with the Iranian Parthian and Sasanian empire having their capital in what is modern-day Iraq for the same centuries-long time span. (Ctesiphon)

Of the four residences of the Achaemenids named by HerodotusEcbatana, Pasargadae or Persepolis, Susa and Babylon—the last [situated in Iraq] was maintained as their most important capital, the fixed winter quarters, the central office of bureaucracy, exchanged only in the heat of summer for some cool spot in the highlands. Under the Seleucids and the Parthians the site of the Mesopotamian capital moved a little to the north on the Tigris—to Seleucia and Ctesiphon. It is indeed symbolic that these new foundations were built from the bricks of ancient Babylon, just as later Baghdad, a little further upstream, was built out of the ruins of the Sassanian double city of Seleucia-Ctesiphon.

According to Iranologist Richard N. Frye:

Throughout Iran's history the western part of the land has been frequently more closely connected with the lowlands of Mesopotamia (Iraq) than with the rest of the plateau to the east of the central deserts [the Dasht-e Kavir and Dasht-e Lut].

— Richard N. Frye, The Golden Age of Persia: The Arabs in the East

Between the coming of the Abbasids [in 750] and the Mongol onslaught [in 1258], Iraq and western Iran shared a closer history than did eastern Iran and its western counterpart.

— Neguin Yavari, Iranian Perspectives on the Iran–Iraq War

Testimony to the close relationship shared by Iraq and western Iran during the Abbasid era and later centuries, is the fact that the two regions came to share the same name. The western region of Iran (ancient Media) was called 'Irāq-e 'Ajamī ("Persian Iraq"), while central-southern Iraq (Babylonia) was called 'Irāq al-'Arabī ("Arabic Iraq") or Bābil ("Babylon").

For centuries the two neighbouring regions were known as "The Two Iraqs" ("al-'Iraqain"). The 12th century Persian poet Khāqāni wrote a famous poem Tohfat-ul Iraqein ("The Gift of the Two Iraqs"). The city of Arāk in western Iran still bears the region's old name, and Iranians still traditionally call the region between Tehran, Isfahan and Īlām "ʿErāq".

During the medieval ages, Mesopotamian and Iranian peoples knew each other's languages because of trade, and because Arabic was the language of religion and science at that time. The Timurid historian Ḥāfeẓ-e Abru (d. 1430) wrote of Iraq:

The majority of inhabitants of Iraq know Persian and Arabic, and from the time of the domination of Turkic people the Turkish language has also found currency.

— Ḥāfeẓ-e Abru

Iraqis share religious and certain cultural ties with Iranians. The majority of Iranians are Twelver Shia (an Islamic sect).

Iraqi culture has commonalities with the culture of Iran. The Mesopotamian cuisine also has similarities to the Persian cuisine, including common dishes and cooking techniques. The Iraqi dialect has absorbed many words from the Persian language.

Kurdistan

Kurds speak a Northwestern Iranian language known as Kurdish. Some historians and linguists, such as Vladimir Minorsky, have suggested that the Medes, an Iranian people who inhabited much of western Iran, including Azerbaijan and Kurdistan, might have been forefathers of modern Kurds.
