Russia

Russia, or the Russian Federation, is a country in Eastern Europe and North Asia. It is the largest country in the world, spanning eleven time zones and sharing land borders with fourteen countries. With a population of over 140 million, Russia is the most populous country in Europe and the ninth-most populous in the world. It is a highly urbanised country, with three-fourths of its population living in urban areas. Moscow, the most populous metropolitan area in Europe, is the capital and largest city of Russia, while Saint Petersburg is its second-largest city and a major cultural centre.

Human settlement on modern Russian territory dates back to the Lower Paleolithic. The emergence of the East Slavs as a prominent group in Europe between the 3rd and 8th centuries AD led to the establishment of Kievan Rus' in the 9th century, which adopted Orthodox Christianity from the Byzantine Empire in 988. Following the disintegration of Kievan Rus' in the 12th century, the Grand Principality of Moscow became the dominant Russian principality and led the unification of Russian lands during the late medieval period, culminating in the formation of the Tsardom of Russia in 1547. By the early 18th century, Russia had expanded vastly through conquest, annexation, and the efforts of Russian explorers. It was proclaimed as the Russian Empire in 1721, which became the third-largest empire in history.
