A #coalitiongovernment 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.  Criticism - Advocates of proportional representation suggest that a coalition government leads to more consensus-based politics, as a government comprising differing parties (often based on different ideologies) need to compromise about governmental policy. Another stated advantage is that a coalition government better reflects the popular opinion of the electorate within a country.[6]  Those who disapprove of coalition governments believe that such governments have a tendency to be fractious and prone to disharmony, as their component parties hold differing beliefs and thus may not always agree on policy.[11] Sometimes the results of an election mean that the coalitions which are mathematically most probable are ideologically infeasible, for example in Flanders or Northern Ireland. A second difficulty might be the ability of minor parties to play "kingmaker" and, particularly in close elections, gain far more power in exchange for their support than the size of their vote would otherwise justify.  Coalition governments have also been criticized[by whom?] for sustaining a consensus on issues when disagreement and the consequent discussion would be more fruitful. To forge a consensus, the leaders of ruling coalition parties can agree to silence their disagreements on an issue to unify the coalition against the opposition.

 The coalition partners, if they control the parliamentary majority, can collude to make the parliamentary discussion on the issue irrelevant by consistently disregarding the arguments of the opposition and voting against the opposition's proposals — even if there is disagreement within the ruling parties about the issue.  Powerful parties can also act in an oligocratic way to form an alliance to stifle the growth of emerging parties. Of course, such an event is rare in coalition governments when compared to two-party systems, which typically exist because of stifling of the growth of emerging parties, often through discriminatory nomination rules regulations and plurality voting systems, and so on.  A single, more powerful party can shape the policies of the coalition disproportionately. Smaller or less powerful parties can be intimidated to not openly disagree. In order to maintain the coalition, they would have to vote against their own party's platform in the parliament. If they do not, the party has to leave the government and loses executive power. However, this is contradicted by the "kingmaker" factor mentioned above.  2016 Irish government formation Event DescriptionThe events surrounding the formation of Ireland's government in 2016 took place during March, April and May of that year, following the general election held on 26 February, which failed to produce an overall majority for any of the country's outgoing political alliances and resulted in a hung parliament.
