Feodor III of Russia

Feodor Alekseyevich became Tsar of all Russia on 1676, inheriting the throne at fifteen with a body that had been failing since childhood. The frailty never stopped the reforms: he pushed through changes that made merit, not bloodline, the ticket into civil and military posts - a direct challenge to the old boyar system. In the same reign he founded the Slavic Greek Latin Academy, Muscovy's first venture into higher education. He died on 7 May 1682, twenty years old, having spent his brief rule remaking the state from a chair he could barely leave.
