The nation's history began with that of the East Slavs, who emerged as a recognizable group in Europe between the 3rd and 8th centuries AD.

Founded and ruled by a noble Viking warrior class and their descendants, the first East Slavic state, Kievan Rus', arose in the 9th century and adopted Orthodox Christianity from the Byzantine Empire in 988, beginning the synthesis of Byzantine and Slavic cultures that defined Russian culture for the next millennium.

Kievan Rus' ultimately disintegrated and the lands were divided into many small feudal states. The most powerful successor state to Kievan Rus' was Moscow, which served as the main force in the Russian reunification process and independence struggle against the Golden Horde.

Moscow gradually reunified the surrounding Russian principalities and came to dominate the cultural and political legacy of Kievan Rus'. By the 18th century, the nation had greatly expanded through conquest, annexation, and exploration to become the Russian Empire, which was the third largest empire in history, stretching from Poland in Europe to Alaska in North America.

The defeat of the Russian Empire in World War I led to the seizure of power by the communists and the formation of the USSR. The brutal rule of Josef STALIN (1924-53) strengthened Russian dominance of the Soviet Union at a cost of tens of millions of lives. The Soviet economy and society stagnated in the following decades until General Secretary Mikhail GORBACHEV (1985-91) introduced glasnost (openness) and perestroika (restructuring) in an attempt to modernize communism, but his initiatives inadvertently released forces that by December 1991 broke up the USSR into 15 independent republics.

Russia established worldwide power and influence from the times of the Russian Empire to being the largest and leading constituent of the Soviet Union, the world's first constitutionally socialist state and a recognized superpower, that played a decisive role in the Allied victory in World War II.

The Soviet era saw some of the greatest technology achievements of the nation, such as the world's first human spaceflight. The Russian Federation was founded following the dissolution of the Soviet Union in 1991, but is recognized as the continuing legal personality of the Soviet state.

Russia has the world's 12th largest economy by nominal GDP or the seventh largest by purchasing power parity, with the fifth largest nominal military budget. It is one of the five recognized nuclear weapons states and possesses the largest stockpile of weapons of mass destruction.

Russia is a great power and a permanent member of the United Nations Security Council, a member of the G8, G20, the Council of Europe, the Asia-Pacific Economic Cooperation, the Shanghai Cooperation Organization, the Eurasian Economic Community, the OSCE, and is the leading member of the Commonwealth of Independent States.
