Ramón Castillo is ousted in a military coup in Argentina.

The 1943 Argentine coup d’état, also known as the Revolution of ’43, was a coup d’état on June 4, 1943, which ended the government of Ramón Castillo, who had been fraudulently elected to office of vice-president, as part of the period known as the Infamous Decade. The military was opposed to Governor Robustiano Patrón Costas, Castillo’s hand-picked successor, the principal landowner in Salta Province, as well as a main stockholder in the sugar industry. The only serious resistance to the military coup came from the Argentine Navy, which confronted the advancing army columns at the Navy’s School of Mechanics.

The heads of state of Argentina during this time period were Arturo Rawson, Pedro Pablo Ramírez and Edelmiro Farrell. During this period, the internal disputes in Argentina about the stance towards World War II, where society and politicians were torn between staying neutral and safely providing foodstuffs to the Allies, or joining the allied side. Ramírez suspended relations with the Axis Powers on January 1944, and Farrell entered the War on March 1945, at a time when the war was mostly decided. The government also saw the rise of Colonel Juan Domingo Perón, a member of the United Officers’ Group, who would become one of the most influential politicians in Argentine history. Perón worked as an assistant to Secretary of War General Edelmiro Farrell during Ramírez’ time in office, and then as the head of a mostly insignificant Department of Labour.
