On March 14, 1613, Tsar Mikhail, after much persuasion, agreed to accept the throne in Kostroma, but he didn’t hurry to move to Moscow. He arrived in Moscow only on May 2, 1613. It was necessary to strengthen the authority of the royal power, to establish relations with social classes and, above all, with the ruling elite.
The author of the article shows that Tsar Mikhail and his entourage coped very successfully with these problems during the march from Kostroma to Moscow. The control over the government, the initiative of operational assignments and solutions of land affairs gradually concentrated in the hands of the tsar. The author shows that Mikhail entered Moscow as an absolute sovereign and that there is no reason to talk about restricting his power in favor of the Boyar Duma and the Zemsky Sobor. During 1613-1618 the composition of the Duma and court ranks was intensively replenished by the Romanovs. Results. The author comes to the conclusion that during the first years of Mikhail Fedorovich’s reign the position of the House of Romanov in the state was significantly strengthened.
