The Kerensky–Krasnov uprising was an attempt by Alexander Kerensky to crush the October Revolution and regain power after the Bolsheviks overthrew his government in Petrograd. It took place between 8 and 13 November 1917. Following the October Revolution, Kerensky fled Petrograd, which fell to the Bolshevik-controlled Petrograd Soviet and went to Pskov, the headquarters of the Northern Front command. He did not get the support of its commander, General Vladimir Cheremisov, who prevented his attempts to gather units to march on Petrograd, but he did get the support of General Pyotr Krasnov, who advanced on the capital with about 700 Cossacks. In Petrograd, opponents of the October Revolution were preparing a revolt that would coincide with the attack on the city by Kerensky's forces.

The Soviets had to improvise the defense of the hills south of the city and wait for the attack of Kerensky's troops, who, despite the efforts of the high command, received no reinforcements. The clash in the Pulkovo Heights ended with the withdrawal of the Cossacks after the Junker mutiny, which failed prematurely, and they did not receive the necessary support from other units to force the defences. Talks between the sides ended with Kerensky's flight, fearful of being handed over to the Soviets by his own soldiers, effectively ending attempts to restore the overthrown Russian Provisional Government.
