[1] On 17 January 1648, Morozov procured the marriage of the tsar with Maria Miloslavskaya, himself marrying her sister, Anna, ten days later, both daughters of Ilya Danilovich Miloslavsky.
[2][3] During his long career at the Kremlin court, Morozov supervised a number of government departments (called prikazy) – Grand Treasury, Streltsy, Pharmacy, and Payroll.
Aspiring to increase the treasury’s income, Morozov reduced salaries of state employees and introduced a high indirect salt tax.
The rebels demanded Morozov's handover, but the tsar hid him in his palace and then sent him in a fictitious exile into the Kirillo-Belozersky Monastery.
[5] In 1649, Morozov took an active part in preparing the Sobornoye Ulozheniye, a legal code which would survive well into the 19th century.
