Juan Yagüe y Blanco, 1st Marquis of San Leonardo de Yagüe was a Spanish military officer during the Spanish Civil War, one of the most important in the Nationalist side. He became known as the "Butcher of Badajoz" because he ordered thousands killed, including wounded Republican soldiers in the hospital.

The Asturian miners' strike of 1934 was a major strike action undertaken by miners in Asturias against the new CEDA-led government, from October 4-19. The strike and subsequent demonstrations eventually developed into a violent revolutionary uprising in an attempt to overthrow the conservative regime. The revolutionaries took over Asturias by force, killing many of the province's police and religious leaders. Armed with dynamite, rifles, and machine guns, they destroyed religious buildings, such as churches and convents. The rebels officially declared a Proletarian Revolution and instituted a local government in the territory. The rebellion was crushed by the Spanish Navy and the Spanish Republican Army, the latter using mainly colonial troops from Spanish Morocco.
