Centrism

Centrism is the range of political ideologies that exist between left-wing politics and right-wing politics on the left–right political spectrum. It is associated with moderate politics, including people who strongly support moderate policies and people who are not strongly aligned with left-wing or right-wing policies. Centrism is commonly associated with liberalism, radical centrism, and agrarianism. Those who identify as centrist support gradual political change, often through a welfare state with moderate redistributive policies. Though its placement is widely accepted in political science, radical groups that oppose centrist ideologies may sometimes describe them as leftist or rightist.

Centrist parties in multi-party systems hold a strong position in forming coalition governments as they can accommodate both left-wing and right-wing parties, but they are often junior partners in these coalitions that are unable to enact their own policies. These parties are weaker in first-past-the-post voting and proportional representation systems. Parties and politicians have various incentives to move toward or away from the centre, depending on how they seek votes. Some populist parties take centrist positions, basing their political position on opposition to the government instead of left-wing or right-wing populism.

Centrism developed with the left–right political spectrum during the French Revolution, when assemblymen associated with neither the radicals nor the reactionaries sat between the two groups. Liberalism became the dominant centrist ideology in the 18th century with its support for anti-clericalism and individual rights, challenging both conservatism and socialism. Agrarianism briefly existed as a major European centrist movement in the late-19th and early-20th centuries. The eugenics associated with the Holocaust caused centrists to abandon scientific racism in favour of anti-racism. Centrism became more influential after the dissolution of the Soviet Union as it spread through Europe and the Americas, but it declined in favour of populism after the 2007–2008 financial crisis.
