In Labastida they demanded libertarian communism. Concerned about the right-wing results of the Spanish elections, the unions linked to the CNT were preparing a revolutionary general strike. The members of the anarchist union of Labastida heard about the plan the day before and decided to join the rebellion. In the early morning, when they heard Haro's signal, bomb sound, they took the guns, they laid siege to the house of the Civil Guard, took the city hall and burned the property registration. The rebellion was held one night.
