In the early 1320s, a Lithuanian army led by Grand Duke Gediminas defeated a Slavic army led by Stanislav of Kyiv at the Battle on the Irpen' River and conquered the city. The Tatars, who also claimed Kyiv, retaliated in 1324–1325, so while Kyiv was ruled by a Lithuanian prince, it had to pay tribute to the Golden Horde. Finally, as a result of the Battle of Blue Waters in 1362, Algirdas, Grand Duke of Lithuania, incorporated Kyiv and surrounding areas into the Grand Duchy of Lithuania.  In 1482, Crimean Tatars sacked and burned much of Kyiv.
