Varangians, Kiev, then Moscow gathered the Russian lands
Russian chronology often starts with the Rus’ state in 862 under Varangian rulers. Prince Oleg took Kiev in 882, uniting northern and southern East Slavs. Christianity from Byzantium in 988 fused Slavic, Scandinavian, and Byzantine cultures for a millennium.
Mongol invasions of 1237–1240 shattered Kievan Rus’. Moscow then rose, and by the late fifteenth century Ivan the Great’s Grand Duchy absorbed neighboring principalities and claimed full sovereignty. Ivan the Terrible made it the Tsardom in 1547; Feodor I’s childless death in 1598 opened the Time of Troubles until Michael Romanov’s 1613 coronation. Seventeenth-century expansion reached the Pacific; Stenka Razin’s revolt flared in 1670–1671. Peter the Great, after the Great Northern War, renamed the realm the Russian Empire in 1721, built St. Petersburg, and forced Western ways. Catherine the Great continued westernization; Alexander I helped defeat Napoleon and raised Russia among the great powers.
Alexander II abolished serfdom in 1861. Later reforms—the 1906 constitution, State Duma, and Stolypin measures—never broke autocracy. World War I mismanagement and economic collapse fed the 1917 revolutions; the October Revolution led to the 1922 treaty creating the Soviet Union. The USSR survived the 1941 Nazi invasion to emerge a Cold War superpower. Gorbachev’s mid-1980s reforms ended in Soviet dissolution; the Russian Federation became the primary successor.
Deep time underlies the politics: Oldowan tools and Homo erectus traces near two million years ago in the North Caucasus; Denisovans around 110,000 years; Ust’-Ishim Homo sapiens about 45,000 years ago in Siberia. Steppe cultures left Sintashta and Pazyryk; Greek colonies framed the Bosporan Kingdom; Khazars ran Volga commerce toward Baghdad. East Slavs settled western Russia from the seventh century, later inviting Varangians such as Rurik in chronicle legend.
