Social democracy has influenced the politics of nearly every major democracy, though it has historically been most successful in the European Union, where it was the predominant ideology from 1945 to 1973. Sweden in particular has historically been closely associated with social democracy, as it was the first country to be led by a social democratic party, and social democrats in Sweden continued to be relevant even after the ideology lost influence in other countries during the 1970s. Social democracy also became a popular ideology in many African governments after the decolonisation of Africa.
Social liberalism, or left liberalism, overlaps significantly with social democracy. This form of liberalism argues in favour of capitalism and the benefits it provides for society, but it also advocates regulations to reduce wealth inequality. It rejects the idea that the upper class seeks to harm or exploit members of society, instead arguing that these are unintentional effects of laissez-faire economics. Left liberalism supports liberal capitalism and a mixed economy, which have been adopted by virtually all liberal nations. Political pluralism and strong social institutions are prioritized by liberalism.
Social liberalism was developed in the United Kingdom in the mid-20th century, where it took the form of new liberalism. The identification of centre-left ideologies as "liberal" is most common to the United States. Liberalism is less common in regions such as Africa and Asia, where there is no individualist or liberal democratic tradition.
Green politics developed from various left-wing ideologies, including social democracy and Marxism, in the 1970s. It was initially developed in Australia and New Zealand, and it first gained influence in Germany as a response to the Cold War and environmental issues. The presence of green politics in national government is mostly limited to Western Europe, Australia, and New Zealand, though green political parties briefly held influence during the postcommunist period of Eastern Europe. Green political parties have been most successful in Belgium, Finland, France, and Germany, where they integrated into the national party system.
In addition to the most common centre-left ideologies, other ideologies are sometimes described as centre-left or have centre-left variants. Democratic socialism supports the abolition of capitalism in favour of socialism, though it opposes the creation of a communist state. It was historically seen as a centre-left position, and may sometimes be described as such; however, modern democratic socialism is typically considered radical in nature and distinct from centre-left ideologies. The Third Way is a variation of social democratic politics that gained prominence in the 1990s after the decline of traditional social democracy. It advocates reform of the social democratic model to emphasize equal opportunity over equality of outcome. To accomplish this, it supports heavy deregulation and privatization for the purpose of increasing economic growth to fund public goods such as education, healthcare, and pensions. The Third Way may be defined as centre-left or as centrist.
The immigration policies of centre-left groups vary depending on the political circumstances of a given country, and they may seek to greatly expand or greatly restrict immigration. In principle, centre-left parties generally believe in multiculturalism and support high immigration. The key issue of centre-left immigration policy is the balance between egalitarianism and pragmatism. The centre-left often faces pressures from working class voters to restrict immigration to prevent competition over jobs and public services. Other centre-left policies can also be negatively impacted by immigration, as a large increase in low-skilled workers can raise concerns about the increased price of public services, prompting spending cuts and roll-backs of centre-left welfare policies.
Though positions on environmentalism are not consistent across centre-left parties, they are more likely to support environmentalist policies than centre-right parties. Centre-left parties are popularly associated with environmental policies in the minds of voters, which earns them support in good economic conditions but loses them support in poor economic conditions. Environmentalism is a major component of green politics.
Progressivism developed as a school of thought within British and American centre-left politics in the mid-19th century. Early progressive thought developed from modernism and humanism, manifesting as calls for reform. It developed as a political movement in the late-19th and early-20th centuries as it was adopted by social liberal and social democratic parties. Unlike later social democratic movements, social democracy in the 19th century held socialist society as an eventual goal. The first social democratic party was established in Germany in 1863.
Social democracy had developed as a major political movement in Europe by the early 20th century as a response to the strength of capitalism. Challenging the idea that capitalism was nearing an implosion, reformist socialists such as Eduard Bernstein rejected Marxist ideas of historical materialism and class conflict, and social democrats established themselves as a reformist alternative to the revolutionary left, arguing that societal improvements within capitalist democracy would better serve the working class. This philosophy became widely popular among the European left after World War I, which had convinced many contemporary leftists that national identity was more important to the working class than class solidarity, which would render Marxism unviable. This was reinforced by the wave of democracy that followed, allowing socialists to participate in electoral politics.
Centre-left politics were historically unpopular in Latin America, and left-wing candidates were kept out of power through both right-wing dictatorships and through conservative victories in fair elections. In the mid-20th century, centre-left politics supported state-led development and industrialization in the region, which allowed redistributive and socially inclusive policies to be implemented. In East Asia, interventionism and developmental policy were adopted by right-wing parties rather than centre-left parties.
Keynesian economics declined in popularity after the end of the post-war consensus, spurred by the 1970s energy crisis and the subsequent recession. The centre-left parties that had held power to that point received much of the blame for the economic crises, and support for the centre-left declined in favour of conservative neoliberalism. At the same time, the end of several right-wing dictatorships in Southern Europe prompted support for centre-left politics among these countries in the 1970s. A decline in the relevance of trade unions, historically a prominent voter group for social democratic parties, contributed to the limited success of centre-left politics in the 1980s. Furthermore, centre-left policies faced new challenges that necessitated a reconsideration of the welfare state, including population ageing that threatened pension programs and women in the workforce that heavily altered the job market. Green political parties first became prominent in the 1980s when they became influential in European politics.
Third Way politics developed as a prominent form of centre-left politics, beginning with the Australian governments of Bob Hawke and Paul Keating in the 1980s and 1990s. Similar movements developed elsewhere, including in Germany and New Zealand. Centre-left parties in Latin America also shifted from social democracy to social liberalism in a pragmatic attempt to reach voters. The most prominent adoption of Third Way politics was that of New Labour in the United Kingdom. Centre-left politics remained unpopular in much of Continental Europe at this time. Third Way politics lost support among the centre-left after the early 2000s, and neo-Keynesianism regained popularity.
By the beginning of the 21st century, the centre-left had almost entirely overtaken further left groups in politics globally, with other forms of left-wing politics seeing little support in democratic nations. Globalization and the Digital Revolution altered the objectives and demographics of the centre-left, as the working class has been largely subsumed by the middle class in developed nations due to increased living standards and the establishment of a knowledge economy. Of those in service industry careers, class is not a unifying or significant aspect of personal identity. In particular, this shift has caused People's Parties based on mass mobilization to be less viable. These rapid developments in society during the turn of the century caused distress among voters, including increased perceptions of social inequality and fear of change, causing voters to move away from traditional centre-left ideologies toward populism.
