Prince of Beloozero
The Prince of Beloozero was the kniaz, the ruler or sub-ruler, of the Principality of Beloozero, a lordship which lasted over two centuries in the north of what is now European Russia. 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, Prince of Rostov, his younger son Gleb Vasilkovich took Beloozero while his older son Boris Vasil'kovich became his successor at Rostov.
The princedom gave rise to the princely nobility surname of Belozersky (Белозе́рский), literally meaning "of Belo Ozero" (of White Lake). Subsequently, the only surviving branch of this Russian Princely family (meaning direct male descendants) are the Princes Belosselsky-Belozersky. Emperor Paul I of Russia gave this honor to Alexander Mikhailovich Belosselsky-Belozersky and his descendants.
