The Tsardom of Russia (Russian: Царство Русское) was the official name for the Russian state between Ivan IV's assumption of the title of Tsar (Emperor) in 1547 and Peter the Great's foundation of the Russian Empire in 1721.
Many Western sources refer to this state as Muscovite Russia or Muscovy, the term originally applied to its predecessor, the Grand Duchy of Moscow. Some researchers consider the propagation of this term in Western Europe as a result of political interests of Poland.. The term Muscovite Tsardom, however, is frequently used by Russian historians and is considered by them to be authentically Russian.
