 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.
