Yaroslav Alexandrovich of Pronsk

Yaroslav Alexandrovich, in baptism Dmitry (1315/1320–1344), was prince of Pronsk from 1340 and grand prince of Ryazan from 1342, son of Alexander Mikhailovich, murdered by Ivan Korotopol of Ryazan in 1340. In 1342 Khan Janibek granted him the Ryazan throne, and with a Tatar army he took Pereyaslavl-Ryazansky, putting Ivan to flight.

Not daring to remain in the city taken with Tatar help, Yaroslav moved his court to Rostislavl-Ryazansky, ruling there until his death in 1344. He was ancestor of the princes of Pronsk.
