In the chaotic first month of the Spanish Civil War (July 1936), the Andalusian city of Ronda became the site of one of the conflict's most brutal early episodes of revolutionary violence.
Ronda, a stronghold of anarchist (CNT) and socialist (UGT) sentiment, fell to the CNT-FAI (National Confederation of Labour / Iberian Anarchist Federation) militias. They established a Revolutionary Committee and declared libertarian communism.
The committee unleashed a wave of executions targeting perceived "class enemies":
Horrified by the uncontrolled violence (which damaged the Republic's international image), the central government in Madrid dispatched Republican Assault Guards and loyal troops. They entered Ronda on July 31, disbanded the Revolutionary Committee, expelled the CNT-FAI militias, and halted the killings.
Ronda became a potent symbol for Nationalist propaganda (Franco's forces) of "Red barbarism." It also sparked intense debate within the Republican zone about revolutionary discipline vs. popular justice. The episode foreshadowed the broader pattern of rear-guard terror on both sides during the war's early months.
