Oleg I of Ryazan

Oleg Ingvarevich, called the Red or the Handsome (c. 1215–1258), was the only senior Ryazan prince to survive Batu's invasion of 1237–1238. Said to have been captured at Kolomna, he refused the khan's demand to convert and was spared for his rare beauty.

He returned to ruined Ryazan in 1243, the first Russian prince to visit Karakorum and return alive. Summoned and detained by the Horde in 1250, he was freed in 1252, took monastic vows, and died on 20 March 1258.
