Spanish Civil War: The Regional Defence Council of Aragon is dissolved by the Second Spanish Republic.

The Spanish Civil War was fought from 1936 to 1939 between the Republicans and the Nationalists. Republicans were loyal to the left-leaning Popular Front government of the Second Spanish Republic and included socialists, anarchists, communists and separatists. The opposing Nationalists who established the Spanish State were an alliance of fascist Falangists, monarchists, conservatives, and traditionalists supported by Nazi Germany and Fascist Italy and led by a military junta among whom General Francisco Franco quickly achieved a preponderant role. Due to the international political climate at the time, the war was variously viewed as class struggle, a religious struggle, or a struggle between dictatorship and republican democracy, between revolution and counterrevolution, or between fascism and communism. The Nationalists won the war, which ended in early 1939, and ruled Spain until Franco's death in November 1975.

The Regional Defence Council of Aragon was an administrative entity created by the Confederación Nacional del Trabajo (CNT) in the context of the Spanish Revolution, during the Spanish Civil War. Until its dissolution, the CRDA controlled and administered the eastern half of Aragon. The price of goods was centrally controlled to mitigate inflation.

The Spanish Republic, commonly known as the Second Spanish Republic, was the form of democratic government in Spain from 1931 to 1939. The Republic was proclaimed on 14 April 1931 after the deposition of King Alfonso XIII. It was dissolved on 1 April 1939 after surrendering in the Spanish Civil War to the Nationalists led by General Francisco Franco.
