The political parties of Chile are three clearly categorized, distinct, political groups: the left-wing, the center and the right-wing. Before the 1973 coup, these three political groups were moderately pluralistic and fragmented.
This distinction has existed since the end of the 19th century. Since then, the three groups have been made up of different parties. Each party has had some amount of power in the management of the State or has been represented in the National Congress.
Political parties are recognized legally and formally by Political Constitution of the Republic of Chile of 1980 and by the Organic Constitutional Law of Political Parties of 1987 as organizations that participate in the legal political system and contribute to guiding public opinion.
History of Chile's political parties
Origins and the first blocks (1810–1860)
In Chile, the first political groups were created during the Independence of Chile: the Royalists and the Patriots. The Royalists wanted to maintain the status quo with the King of Spain, while the Patriots wanted to gain a larger degree of freedom. In turn, the Patriots further split into the Moderates, who wanted a slow pace of reform, and the Radicals or Extremists, who favored a much faster pace. All of the early political groups were shy of advocating for full independence since it was unknown if the King would regain his power from Napoleon.
Once Chile gained independence, many political groupings emerged. They were based on various popular leaders during that time, instead of common political ideas. Two very strong political groupings were the Pipolos (liberals) and the Pelucónes (conservatives). Two minor parties, the O’Higginists and the Tobacconists, were often on the Pelucónes' side. After Diego Portales Palazuelos became the architect of the New Institution and the Constitution of 1833, the Pelucónes prevailed for thirty years (1831–1861).
From 1831 to 1861, the prevailing political system was one in which the President co-opted a successor. This system greatly influenced the idea that power should be transferred between members of the ruling political faction. It was only the "Question of the Sacristan" (1856), which divided The Pelucónes, allowed for the rise of the Liberals to power in 1861.
Dominance of the traditional parties (1860–1920) The formal emergence of political parties in Chilean institutions occurred around the 1850s. Chileans began to challenge the President as the leading role in national political life through the National Congress. In 1891, the disagreement was resolved after a Civil War, in favor of a parliamentary system.
Around that time, the rise of the middle class would eventually lead to the creation of the Radical Party. Their campaign started in the 1850s, as a group defending the interests of the silver mine owners, but it would gradually shift its focus to the employees of the growing state bureaucracy. Soon afterwards, from the same branch of radicalism, the Democratic Party appeared. It was a community that was born closer to the working class segment of society, but that over time would join the game of alliances within the rest of the party system.
After the Chilean Civil War of 1891, the political system began to embody elements of a parliamentary system. Hence, the political coalitions became very strong. Although around twenty distinct political parties and movements existed, Chilean politics was structured around two large groups: the Liberal Alliance (of Liberal and Progressive tendency) and the Coalition (Conservative, Catholics). At the same time, political parties, formerly tools of the upper-class, expanded to include the thriving middle and working classes too.
Expansion of political parties (1920–1973) With the rise of immigration from Europe, workers with anarchist and socialist ideas came to Chile. Additionally, in the mid-19 century, the union movement began in the nitrate fields of the north of Chile through a surge of the joint labor unions. It is from these processes that in 1912, the Workers' Socialist Party was founded in Iquique by the typographer Luis Emilio Recabarren and 30 union workers and employees. The Workers' Socialist Party is defined as the political party of the Chilean working class. In 1922, the party joined the Third Communist International. Since that date, the party has been known as the Communist Party of Chile.
In the period between 1920 and 1938 (between the start of the first presidential term of Arturo Alessandri Palma and the end of his second term) a series of political incidents led to the loss of the importance of traditional nineteenth-century parties, but for the benefit of the "party masses".
