The document summarizes the early history of Russia, beginning with the Rus people who migrated from northern Europe and brought order to the Slavs in the region. Christianity then spread to Russia through the efforts of Byzantine monks Cyril and Methodius who developed the Cyrillic alphabet and Slavonic mass. Grand Duke Vladimir converted to Christianity in 988 and made it the state religion. Russia was later attacked by internal princes seeking more power, and then faced invasions by the Mongols in the 1200s and Swedes and Teutonic Knights in the 1240s, before emerging as the nation of Muscovy in the late 1400s after freeing itself from foreign domination.
