A coalition government in a parliamentary system is a government in which multiple 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 parliament. 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 desires while also playing 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.

When a general election does not produce a clear majority for a single party, parties either form coalition cabinets, supported by a parliamentary majority, or minority cabinets which may consist of one or more parties. Cabinets based on a group of parties that command a majority in parliament tend to be more stable and long-lived than minority cabinets. While the former are prone to internal struggles, they have less reason to fear votes of no confidence. Majority governments based on a single party are typically even more stable, as long as their majority can be maintained. Countries which often operate with coalition cabinets include: the Nordic countries, the Benelux countries, Australia, Austria, Cyprus, France, Germany, Greece, India, Indonesia, Ireland, Israel, Italy, Japan, Kenya, Kosovo, Lithuania, Latvia, Lebanon, Nepal, New Zealand, Pakistan, Thailand, Trinidad and Tobago, Turkey and Ukraine. Switzerland has been ruled by a coalition of the four strongest parties in parliament from 1959 to 2008, called the 'Magic Formula'. Between 2010 and 2015, the United Kingdom also operated a formal coalition between the Conservative and the Liberal Democrat parties, but this was unusual: the UK usually has a single-party majority government. In the United Kingdom, coalition governments (sometimes known as 'national governments') usually have only been formed at times of national crisis. The most prominent was the National Government of 1931 to 1940. There were multi-party coalitions during both world wars. Apart from this, when no party has had a majority, minority governments normally have been formed with one or more opposition parties agreeing to vote in favour of the legislation which governments need to function: for instance the Labour government of James Callaghan formed a pact with the Liberals from March 1977 until July 1978, after a series of by-election defeats had eroded Labour's majority of three seats which had been gained at the October 1974 election. However, in the run-up to the 1997 general election, Labour opposition leader Tony Blair was in talks with Liberal Democrat leader Paddy Ashdown about forming a coalition government if Labour failed to win a majority at the election; but there proved to be no need for a coalition as Labour won the election by a landslide. The 2010 general election resulted in a hung parliament (Britain's first for 36 years), and the Conservatives, led by David Cameron, which had won the largest number of seats, formed a coalition with the Liberal Democrats in order to gain a parliamentary majority, ending 13 years of Labour government. This was the first time that the Conservatives and Lib Dems had made a power-sharing deal at Westminster. It was also the first full coalition in Britain since 1945, having been formed 70 years virtually to the day after the establishment of Winston Churchill's wartime coalition,Labour and the Liberal Democrats have entered into a coalition three times in the Scottish Parliament and twice in the Welsh Assembly. In Germany, for instance, coalition government is the norm, as it is rare for either the Christian Democratic Union of Germany together with their partners the Christian Social Union in Bavaria (CDU/CSU), or the Social Democratic Party of Germany (SPD), to win an unqualified majority in a national election. Thus, at the federal level, governments are formed with at least two parties. For example, Helmut Kohl's CDU governed for years in coalition with the Free Democratic Party (FDP); from 1998 to 2005 Gerhard Schröder's SPD was in power with the Greens; and from 2009 Angela Merkel, CDU/CSU was in power with the FDP. 'Grand coalitions' of the two large parties also occur, but these are relatively rare, as large parties usually prefer to associate with small ones. However, if none of the larger parties can receive enough votes to form their preferred coalition, a grand coalition might be their only choice for forming a government. This was the situation in Germany in 2005 when Angela Merkel became Chancellor: in early elections, the CDU/CSU did not garner enough votes to form a majority coalition with the FDP; similarly the SPD and Greens did not have enough votes to continue with their formerly ruling coalition. A grand coalition government was subsequently forged between the CDU/CSU and the SPD. Partnerships like these typically involve carefully structured cabinets. The CDU/CSU ended up holding the Chancellery while the SPD took the majority of cabinet posts. Parties frequently make statements ahead of elections which coalitions they categorically reject, similar to election promises or shadow cabinets in other countries. In Germany, coalitions rarely consist of more than two parties (CDU and CSU, two allies which always form a single caucus, are in this regard considered a single party). However, in the 2010s coalitions on the state level increasingly included three different parties, often FDP, Greens and one of the major parties or 'red red green' coalitions of SPD, Linkspartei and Greens. By 2016, the Greens have joined governments on the state level in eleven coalitions in seven various constellations. Armenia became an independent state in 1991, following the collapse of the Soviet Union. Since then, many political parties were formed in it, who mainly work with each other to form coalition governments. Currently the country is governed by the My Step Alliance coalition after successfully gaining a majority in the National Assembly of Armenia following the 2018 Armenian parliamentary election. In federal Australian politics, the conservative Liberal, National, Country Liberal and Liberal National parties are united in a coalition, known simply as the Coalition. The Coalition has become so stable, at least at the federal level, that in practice the lower house of Parliament has become a two-party house, with the Coalition and the Labor Party being the major parties. This coalition is also found in the states of New South Wales and Victoria. In South Australia and Western Australia the Liberal and National parties compete separately, while in the Northern Territory and Queensland the two parties have merged, forming the Country Liberal Party, in 1978, and the Liberal National Party, in 2008, respectively.
