From Wikipedia, the free encyclopedia
 
A coalition government is a form of government in which political parties cooperate, reducing the dominance of any one party within that "coalition". The usual reason for this arrangement is that no party on its own can achieve a majority in the election. A coalition government might also be created in a time of national difficulty or crisis (for example, during wartime or economic crisis) to give a government the high degree of perceived political legitimacy or collective identity, it can also play a role in diminishing internal political strife. In such times, parties have formed all-party coalitions (national unity governments, grand coalitions). If a coalition collapses, a confidence vote is held or a motion of no confidence is taken.
