The July 1936 military uprising in Barcelona was a military uprising in Barcelona, the capital and main city of Catalonia, Spain on 19 July 1936 which contributed to the start of the Spanish Civil War. Most of the army officers in the city supported the coup, but the Civil Guard and the Assault Guard (Guardia de Asalto) remained loyal to the government. Furthermore, Barcelona was one of the strongholds of the anarchist union, the Confederación Nacional del Trabajo (CNT). The rebel troops were defeated after bloody combat.
