The July Days were a period of unrest in Petrograd, Russia, between 16–20 July [O.S. 3–7 July] 1917. It was characterised by spontaneous armed demonstrations by soldiers, sailors, and industrial workers engaged against the Russian Provisional Government. The demonstrations were angrier and more violent than those during the February Revolution months earlier.

The Russian Provisional Government was a provisional government of the Russian Empire and Russian Republic, announced two days before and established immediately after the abdication of Nicholas II. The intention of the provisional government was the organization of elections to the Russian Constituent Assembly and its convention. The provisional government, led first by Prince Georgy Lvov and then by Alexander Kerensky, lasted approximately eight months, and ceased to exist when the Bolsheviks gained power in the October Revolution in October [November, N.S.] 1917.
