The defeat of the military rebellion against the Republican government in Barcelona placed Catalonia firmly in the Republican side of the Spanish Civil War. During the war, there were two rival powers in Catalonia: the de jure power of the Generalitat and the de facto power of the armed popular militias. Violent confrontations between the workers' parties (CNT-FAI and POUM against the PSUC) culminated in the defeat of the first ones in 1937. The situation resolved itself progressively in favor of the Generalitat, but at the same time the Generalitat was partially losing its autonomous power within Republican Spain. In 1938 Nationalist troops broke the Republican territory in two, isolating Catalonia from the rest of the Republic. The defeat of the Republican army in the Battle of the Ebro led in 1938 and 1939 to the final defeat of the Catalonian Republican forces in the Catalonia Offensive, who abolished the Catalan autonomy and brought it into Spain proper.
