The Kerensky offensive, also called the summer offensive, the June offensive in Russia, or the July offensive in Western historiography, took place from 1 July [O.S. 18 June] to 19 July [O.S. 6 July] 1917 and was the last Russian offensive of World War I. After the abdication of Emperor Nicholas II during the February Revolution, the Russian Provisional Government pledged to fulfill Russia's existing commitments to the Triple Entente, which included launching an offensive in the spring of 1917. The operation was directed at capturing Lemberg and the rest of Galicia from Austria-Hungary.
