The anarchist insurrection of December 1933, also known as the December 1933 Revolution, was a revolutionary general strike accompanied by the action of armed militias that had its epicenter in the city of Zaragoza, and in general in Aragón and La Rioja. It tried to implement libertarian communism, and that it extended by points of Extremadura, Andalusia, Catalunya and the mining basin of León. December 1933 was the third and last of the insurrections carried out by the CNT during the Second Republic.
It began in Zaragoza on December 8, 1933, the same day that the new Republican Courts met after the electoral victory of the center-right Radical Republican Party and the Catholic right of the CEDA. By one week later, on December 15, the insurrection had been completely dominated by law enforcement and even by the intervention of the army. On December 18, the first government of the Radical Republican Party was formed, chaired by Alejandro Lerroux during the Second Biennium of the Second Spanish Republic, with support from outside the CEDA.
