The Lankaran Uprisings (Azerbaijani: Lənkəran üsyanları) were a series of several armed uprisings in the southern districts of Azerbaijan against the Soviet regime starting from July 1920. The early attempts of rebellion were successful, bringing crushing blows upon the local Soviet forces and taking control of many districts in the southernmost districts of the Azerbaijani SSR. But additional Soviet forces were sent to the region via Baku in 1921 and the guerillas couldn't compete with the Soviet naval support from the Caspian Sea. Two more uprisings were commended until 1922, when the Soviet authority finally got full control of the region.
