Born again in this new age of fire and sword, Russia sees itself under a powerful dynasty of Tsars bent on reclaiming land lost to the Polish Commonwealth. The Muscovite Tsardom was actually called the Tsardom of Russia, the Tsardom of Muscovy, as well as the Tsardom of Rus'. The Tsardom lasted from Ivan the Terrible's assumption of the title of Tsar in 1547 until Peter the Great's foundation of the Russian Empire in 1721. A large part of this time period in Russian history was the Time of Troubles; this period was comprised of the years of interregnum between the death of the last Russian tsar of house Rurikovich, Feodor Ivanovich and the establishment of the Romanov dynasty. With Fire & Sword occurs after the Time of Troubles.
