Although the Marshal of Ayacucho, Antonio José de Sucre Alcalá, had organized the first Bolivian police force on June 24, 1826, the National Police ("Policía Nacional") was not established officially until 1886. The Bolivian police became institutionalized on the national level in 1937 with the creation of the National Corps of Carabineers ("Cuerpo Nacional de Carabineros") and its professional training school, the Police School ("Escuela de Policía"), later renamed the National Police Academy ("Academia Nacional de Policías"). The carabineers constituted a post-Chaco War merger of the military police, the Gendarmerie Corps ("Cuerpo de Gendarmería"), the paramilitary Security Police ("Policía de Seguridad") and the Army's Carabineer Regiment ("Regimiento de Carabineros").
