The Great Northern War in Ukraine (1708–1713) — war between the Tsardom of Russia on one hand and the Swedish Empire and the Ottoman Empire on the other. Since the beginning of the Great Northern War, Ukraine, as a satellite of the Tsardom of Russia, had been supplying Moscow troops with manpower, ammunition, fodder and food. With the arrival of Charles XII in Ukraine, hetman Ivan Mazepa concluded the Ukrainian-Swedish Alliance with the King and opposed Peter I. Following the Hetman, the Zaporozhian Army led by kosh otaman Kost Hordienko also joined the Swedes.
