In October 1934, the Asturian Revolution erupted in the coal-mining region of Asturias, northern Spain, when socialist and anarchist workers staged a full-scale uprising against the conservative government. The revolutionaries seized control of the region for nearly two weeks, establishing workers' committees and engaging in fierce urban combat. The rebellion was brutally suppressed by the Spanish Army, led by General Francisco Franco, using Moroccan colonial troops, resulting in thousands of deaths and mass arrests that foreshadowed the civil war.

The Asturian Revolution became a defining symbol of working-class resistance for Spanish poets. Miguel Hernández, then a young poet, wrote powerful verses in support of the Asturian miners, and the event shaped the social realism that would dominate his later work. The brutal suppression also radicalized many intellectuals who had previously been moderate Republicans, pushing them toward more militant positions.
