The Aleria standoff was a confrontation between members of the French Gendarmerie and Corsican nationalist militants who entrenched themselves in a wine cellar at Aleria, Corsica, on 21 and 22 August 1975. The armed activists belonged to the radical nationalist party Action Régionaliste Corse (ARC). The occupation resulted in a strong reaction of the French government and is regarded as the precursor of the Corsican conflict.
