Moscow Kingdom, Moscow State, Muscovy (Russian: Московское государство, Московское царство, Latin: Moscovia); according to another version - the Russian Empire, the Russian Empire (Russian: Русское царство; Российское царство) - a centralized state in the late XV-early XVIII centuries, from the adoption of Ivan IV the Terrible the title of tsar in 1547 to the founding of the Russian Empire by Peter I in 1721 .
The name Moscow Kingdom also appears in the Conciliar Act of 1649 ("Moscow State").
Some sources point to another name: in the Moscow Acts of 1571, Ivan the Terrible calls himself "Sovereign, Tsar and Grand Duke of All Russia." Ukrainian historian Kirill Galushko in the Ukrainian encyclopedia points out that initially (until 1547) the state was called - the Grand Duchy of Moscow, and in 1547-1721 - the Russian Empire.
According to Russian historians, Ivan the Terrible ascended the throne and called himself the Tsar of All Russia and proclaimed the name of his state as the Russian Empire. Similarly, the German map of 1573 shows the name "Russia" ("Ryssia") "Grand Duke of Moscow Ivan IV the Terrible in 1547 proclaimed himself king and was crowned king, began to use the title: , Moscow, Novgorod, Tsar of Kazan, Tsar of Astrakhan, lord of Pskov and Grand Duke of Smolensk, Tver, Ugra, Perm, Vyatka, Bulgaria and other states, and Grand Duke of Novgorod Nizov land, Chernihiv "(Russian -" Vladimir, Moscow, Novgorod, Tsar of Kazan, Tsar of Astrakhan, Emperor of Pskov and Grand Duke of Smolensk, Tver, Ugra, Perm, Vyatka, Bulgaria and other states and Grand Duke of Novgorod Nizovsky lands, Chernigov "), later, with the expansion of the borders of the Moscow Kingdom, : "King of Siberia, Lord and lord of the Iberian land, Kartal and Georgian kings and Kabardino-Balkarian land, Circassian and Mountain princes" (ro c - "Tsar of Siberia, Sovereign and Sovereign of the Iberian lands, Kartal and Georgian kings and Kabardino-Balkarian lands, Cherkasy and Mountain Princes").
However, this did not change his vassal dependence on the Crimean khans, as the agreement concluded was in force.
