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.

The Spanish coup of July 1936 was a nationalist and military uprising that was intended to overthrow the Spanish Second Republic but precipitated the Spanish Civil War; Nationalists fought against Republicans for control of Spain. The coup was organized for 18 July 1936, although it started the previous day in Spanish Morocco, and resulted in a split of the Spanish military and territorial control, rather than a prompt transfer of power. The resulting war, Western neutrality, and active Axis support ultimately led to the establishment of a nationalist regime under Francisco Franco, who became ruler of Spain as caudillo.
