Boris Morozov

Boris Ivanovich Morozov (1590–1661) was a boyar who headed the Russian government in the early reign of Tsar Alexis, whose tutor he became in 1634. In 1648 he arranged Alexis's marriage to Maria Miloslavskaya and soon after married her sister Anna, becoming the tsar's brother-in-law.

He cut salaries and imposed a heavy salt tax, provoking the Salt Riot of 1648; the tsar saved him from the mob by a feigned exile to the Kirillo-Belozersky Monastery. Back in Moscow, he helped draft the 1649 legal code, the Sobornoye Ulozheniye, and continued to direct the government in the early 1650s.
