Independent Democratic Union
The Independent Democratic Union (Unión Demócrata Independiente, UDI) is a Chilean right-wing, conservative political party, founded in 1983. Its founder was the lawyer, politician and law professor Jaime Guzmán, a civilian who collaborated with Augusto Pinochet. Guzmán was a senator from 1990 until his assassination on April 1, 1991.
Its ideological origins date back to Guzmán's Guildist Movement, born out of the Pontifical Catholic University of Chile in 1966, espousing the independence and depoliticization of intermediate bodies of civil society.
UDI, together with National Renewal (RN) and other minor movements, formed a coalition of right-wing parties called Coalition for Change, which is the successor to Alliance for Chile and rose to power in March 2010, after victory in the presidential elections of January 2010. It was the largest political party in Congress between 2010 and 2014.
In the Chilean parliamentary election, 2009, UDI held the largest majority in the election of deputies, electing 40 deputies (one third of the House) with 23.04% (1,507,001 votes), and got 21.21% (369,594 votes) in the election of senators. Its bench is the largest obtained by a single party in Chile since 1990. UDI currently has 39 deputies and 8 senators.
