Radical Civic Union

The Radical Civic Union (, UCR) is a major political party in Argentina. It has reached the national government on ten occasions, making it one of the most historically important parties in the country. Ideologically, the party has stood for radicalism, secularism and universal suffrage. Especially during the 1970s and 1980s, it was perceived as a strong advocate for human rights. Its factions however, have been more heterogeneous, ranging from conservative liberalism to social democracy.

Founded in 1891 by Leandro N. Alem, it is the second oldest political party active in Argentina. The party's main support has long come from the middle class. On many occasions, the UCR was in opposition to Peronist governments and declared illegal during military rule. Since 1995 it has been a member of the Socialist International (an international organisation of social democrat political parties).

The UCR had different fractures, conformations, incarnations and factions, through which the party ruled the country seven times with the presidencies of Hipólito Yrigoyen (1916-1922 and 1928-1930), Marcelo Torcuato de Alvear (1922-1928), Arturo Frondizi (1958-1962), Arturo Illia (1963-1966), Raúl Alfonsín (1983-1989) and Fernando de la Rúa (1999-2001). After 2001, the party has been particularly fragmented. As the Justicialist Party led by Nestor and Cristina Kirchner moved to the left, the UCR aligned itself with anti-Peronist centre-right parties.

From 2015 to 2023, the UCR was a member of the centre-right Cambiemos / Juntos por el Cambio coalition, along with Republican Proposal and Civic Coalition ARI, and supported Mauricio Macri in the 2015 and 2019 presidential elections. For the 2023 elections, the party supported the candidacy of Patricia Bullrich. The party is not currently in any coalition since Juntos por el Cambio's dissolution in 2023. Provided by Wikipedia
