Knyaz - Russia

Russia

As Tsardom of Russia gained dominion over much of former Kievan Rus', Velikii Kniaz Ivan IV of Russia in 1547 was crowned as Tsar. From the mid-18th century onwards, the title Velikii Kniaz was revived to refer to (male-line) sons and grandsons of Russian Emperors. See titles for Tsar's family for details.

Kniaz (Russian: Кня́зь, ) continued as a hereditary title of Russian nobility patrilineally descended from Rurik (e.g., Belozersky, Belosselsky-Belozersky, Repnin, Gorchakov) or Gediminas (e.g., Galitzine, Troubetzkoy). Members of Rurikid or Gedyminid families were called princes when they ruled tiny quasi-sovereign medieval principalities. After their demesnes were absorbed by Muscovy, they settled at the Moscow court and were authorised to continue with their princely titles.

From the 18th century onwards, the title was occasionally granted by the Tsar, for the first time by Peter the Great to his associate Alexander Menshikov, and then by Catherine the Great to her lover Grigory Potemkin. After 1801, with the incorporation of Georgia into the Russian Empire, various titles of numerous local nobles were controversially rendered in Russian as "kniazes". Similarly, many petty Tatar nobles asserted their right to style themselves "kniazes" because they descended from Genghis Khan.

Finally, within the Russian Empire of 1809-1917, Finland was officially called Grand Principality of Finland (fi Suomen suuriruhtinaskunta, sv Storfurstendömet Finland, ru Velikoye Knyazhestvo Finlyandskoye).
