Prince of Beloozero

The Prince of Beloozero (князь белоозерский) was the title of the ruler of the Principality of Beloozero.

History
Before 1238, it formed part of the Principality of Rostov, which also included the lands around Yaroslavl, Uglich and Ustyug. It was detachted from Rostov in 1238 when, following the death of Vasilko Konstantinovich, the prince of Rostov, his younger son Gleb Vasilkovich took Beloozero while his older son Boris Vasilkovich became his successor at Rostov.

The princedom gave rise to the princely noble surname of Belozersky (Белозерский). Subsequently, the only surviving branch of this Russian princely family (meaning direct male descendants) are the princes Belosselsky-Belozersky. Emperor Paul I gave this honor to Alexander Mikhailovich Belosselsky-Belozersky and his descendants.
