Stanislav of Kyiv
The sixteenth-century Belarusian-Lithuanian chronicles make Stanislav the last Rurikid prince of Kyiv. They relate that the Lithuanian grand duke Gediminas invaded and in 1320 defeated him and his allies at the battle on the Irpin River, after which Stanislav fled to Bryansk and then to Ryazan.
In Ryazan the prince gave him his daughter Olga in marriage. These accounts were first written down two centuries after the events, and Stanislav has also been identified with the Kyivan prince Fyodor.
