of 1890. The party was a breakaway from the
Civic Union, which was led by
Bartolomé Mitre and
Leandro Alem. The term 'radical' in the party's name referred to its demand for
universal male suffrage, which was considered radical at the time, when Argentina was ruled by an exclusive oligarchy and government power was allocated behind closed doors. The Civic Union led an attempt to force the early departure of President
Miguel Juárez Celman in the
Revolution of the Park (
Revolución del Parque). Eventually a compromise was reached with Juárez Celman's government. Hardliners who opposed this agreement founded the current UCR, led by Alem's nephew
Hipólito Yrigoyen. In
1893 and
1905, the party led further attempts to overthrow the government. With Alem's death in 1896, the party disbanded at the turn of the century before being revived by Yrigoyen in 1903. The party pressured the conservative government to implement democratic reforms. In 1997, the UCR participated in elections in coalition with
Front for a Country in Solidarity (FREPASO), itself an alliance of many smaller parties. This strategy brought
Fernando de la Rúa to the presidency in the
1999 elections. During
major riots triggered by economic reforms implemented by the UCR government (with the advice of the
International Monetary Fund), President de la Rúa resigned and fled the country to prevent further turmoil. After three consecutive acting presidents assumed and resigned their duties in the following weeks,
Eduardo Duhalde of the PJ took office until new elections could be held. After the
2001 legislative elections, the party lost and became the second-largest party in the federal
Chamber of Deputies, winning 71 of 257 seats. It campaigned in an alliance with the smaller, more leftist FREPASO. The party has subsequently declined markedly and its candidate for president in 2003,
Leopoldo Moreau, gained just 2.34% of the vote, beaten by three Peronists and more seriously, by two former radicals,
Ricardo López Murphy of
Recrear and
Elisa Carrió of
ARI, who have leached members, support and profile from the UCR. Since
Nestor Kirchner's led peronist PJ switched into political left, the UCR start to alliance with center-right anti-peronists. In the
2005 legislative elections, the UCR was reduced to 35 deputies and 13 senators, but remains the second force in Argentine politics. Ahead of the 2007 election, the remaining Radicals divided, between those who wanted to find an internal candidate and those who wanted to back a candidate from another movement, mostly former economy minister
Roberto Lavagna, supported by former president Raúl Alfonsín. In May 2005, the National Committee of the UCR, then led by
Ángel Rozas, intervened (suspended of authorities of) the Provincial Committee of the UCR in
Tierra del Fuego Province after Radical governor
Jorge Colazo spoke in favour of Kirchner's reelection. The intervention was rejected by the Provincial Committee. A party convention held in
Rosario in August 2006 officially rejected the possibility of alliances with Kirchner's faction of Justicialism and granted former Party President
Roberto Iglesias the permission to negotiate with other political forces. This led to several months of talks with Lavagna. The continued dissidence of the
Radicales K prompted the intervention of the UCR Provincial Committee of
Mendoza on 1 November 2006, due to the public support of President Kirchner by Mendoza's governor, the Radical
Julio Cobos. The measure was short-lived, as the Mendoza Province Electoral Justice overturned it three days later. Deputy and UCR National Committee Secretary General
Margarita Stolbizer stated that the party is virtually "broken due to the stance of the leaders who support the alliance [with Kirchner]". Roberto Iglesias eventually resigned the presidency of the party in November 2006 due to differences with Lavagna, having reached the conclusion that an alliance with him would be a mistake, and joined Stolbizer's camp, maintaining that the party should look for its own candidate (the so-called
Radicales R). On 1 December 2006 the National Committee appointed
Jujuy Province Senator
Gerardo Morales as its new president. Morales stated that he wanted to follow the mandate of the Rosario convention (that is, looking for a possible alliance with Roberto Lavagna). Morales went on to become Lavagna's running mate in the
presidential election of October 2007, coming third. Although this campaign represented the mainstream of the national UCR leadership, substantial elements backed other candidates, notably the
Radicales K. Cobos was elected vice president as the running mate of Cristina Fernández de Kirchner through the
Plural Consensus alliance, and several Radicals were elected to Congress as part of the Kirchners'
Front for Victory faction. The official UCR ranks in Congress were reduced to 30 in the
Argentine Chamber of Deputies and 10 in the
Argentine Senate. In recent years, the UCR has been riven by an internal dispute between those who oppose and those who support the left-wing policies of Peronist President
Cristina Fernández de Kirchner and her husband and predecessor
Néstor Kirchner. However, most
Radicales K support for the Kirchners ended by mid 2008, when
Vice President Julio Cobos opposed the
Government bill on agricultural export taxes. He later rejoined UCR, becoming a prominent figure in the opposition, despite being still the Vice President. The UCR joined the
Civic and Social Agreement to run for the
2009 elections. The loose coalition obtained 29% of the national votes and came a close second to the
Front for Victory and allies national outcomes. The Party's reorganization, as well as the 2009 elections, resulted in a gain of party representatives in the
National Congress. In 2015, the UCR formed a
coalition with
Republican Proposal, a
center-right political party, to form
Cambiemos. Cambiemos won the
presidential election, which ended its 12 years of opposition. The alliance with Republican Proposal was criticized by the
Socialist International and the Young Radicals were suspended from the
International Union of Socialist Youth. ==Ideology and factions==
