Popular Union (Spanish: Unión Popular) is a political party in Argentina rooted in Peronism. Established by Juan Atilio Bramuglia as both a contingency for Peronists displaced by the 1955 military coup against the populist President Juan Perón, it became a "neo-Peronist" alternative to the exiled leader's line, and subsequently, an alternative to the successive dominant factions in the Justicialist Party. The UP re-emerged as a political force during the 2011 elections, when it was adopted as a vehicle by Eduardo Duhalde ahead of the Federal Peronist primaries on August 14.
