Alexander Mikhailovich of Pronsk
Alexander Mikhailovich (c. 1295–1340) was prince of Pronsk and the only son of Mikhail Yaroslavich. In 1340, while escorting tribute to the khan of the Golden Horde, he was seized on the road by his cousin Ivan Korotopol, grand prince of Ryazan, who carried him to Pereyaslavl-Ryazansky and had him killed.
His son Yaroslav, baptized Dmitry, succeeded as prince of Pronsk and, with Tatar backing, drove Ivan from Ryazan in 1342.
