Russo-Turkish War). Following the loss in the Crimean War, in Russia started intensively to be installed a network of railroads and in 1869 in Kryukiv were built small railcar repair shops, while in 1872 the city of Kriukiv was connected with Kremenchuk by a railroad bridge over Dnieper. In 1870 in Kremenchuk was built a factory in production and maintenance of agrarian equipment and iron cast products. In 1899 in Kremenchuk was introduced a network of tramway transportation that existed until the complete establishment of Soviet regime in Ukraine in 1921. During the Russian February Revolution of 1917 the power in city was controlled by a council (soviet) of workers' deputies which was dominated by the Russian Social Democratic Labour Party and the head of the city council became a future Ukrainian Communist leader Yuriy Lapchynskyi. During the Ukrainian–Soviet War, on 26 January 1918 the Russian Bolshevik troops secured the city, however already in February of the same year they had to withdraw due to the treaty of Brest-Litovsk and advance of German and Ukrainian armies. Following the World War I hostilities between the Bolshevik Russia and Ukraine renewed and on 1 February 1919 the Russian Red Army once again secured the city. However, in May of the same year Kremechuk was engulfed in the insurgency of Otaman Grigoriev who earlier sided with Bolsheviks and drove the international force of Triple Entante from Odessa. From July to December 1919 the city was occupied by the Russian "White Guard" troops of Anton Denikin. Following their withdrawal, the Denikin's troops blew up the railroad bridge. In 1920–1922, the city was an administrative center of briefly existed Kremenchuk Governorate during a peasant insurgency (Kholodnyi Yar) near Chyhyryn (just west of the city). During 1930s the Kremenchuk's industry was transformed, its Kriukiv railcar repair shops became a railcar manufacturing factory, while its factory in production of agrarian equipment changed to manufacturing road equipment. During World War II (1939-1945), Kremenchuk suffered heavily under Nazi occupation. It was occupied from September 15, 1941, to September 29, 1943. More than 90% of the city's buildings were leveled over the course of the war. 29 September, the day when the city was liberated from the Nazis in 1943, is celebrated in Kremenchuk as the City Day.
