Ivan II Korotopol

Ivan II Ivanovich, called Korotopol (died 1343), was prince of Ryazan, son of Ivan Yaroslavich. He is thought to have succeeded in 1327 after his father was executed by Öz Beg Khan of the Golden Horde, and later campaigned with Moscow against Novgorod and with a Horde army against Smolensk.

On the Smolensk march he robbed his cousin Alexander of Pronsk, took him to Pereyaslavl and killed him there. In 1342 Alexander's son brought Tatar troops against him and besieged Pereyaslavl; Ivan resisted for a day, fled by night and died the following year.
