Prince of Tver

The Prince of Tver (Russian: Князь тверской) was the ruler of the Principality of Tver. The princes of Tver descended from the first prince, Yaroslav Yaroslavich (r.1247–1271). They are also known as the "Iaroslavichi" or "Yaroslavichi of Tver", or the "Mikhailovichi of Tver". In 1485, Tver was formally annexed by Moscow and became an appanage.
