PUCA was originally established as a cultural grouping advocating 'Central Americanization' in 1904. Renamed the Committee of State in 1944, it began to act as a political party after the Sandanistas gained power in 1979. PUCA received legal status after the 1984 elections. As of 2006, PUCA is in the Constitutionalist Liberal Party electoral alliance.
