Capital and largest city (pop., 2006 est.: 10,425,075) of Russia. It is located on both sides of the Moskva River in western Russia, about 400 mi (640 km) southeast of St. Petersburg and about 600 mi (970 km) east of Poland. Inhabited since Neolithic times, the site was first mentioned as a village in 1147 and became the capital of the principality of Moscow (Muscovy) in the late 13th century. It expanded in the 15th and 16th centuries under its grand dukes Ivan III and Ivan IV and became the capital of a united Russia (1547–1712). In 1812 it was occupied by the French under Napoleon and was almost entirely destroyed by fire. In 1918 it became the capital of the Union of Soviet Socialist Republics and expanded greatly. It suffered much damage from German bombing in World War II. In 1993 it was the scene of armed conflict between opposing government factions after the dissolution of parliament by Boris Yeltsin. The spiritual home of the Russian Orthodox church for more than 600 years, it is a political, industrial, transportation, and cultural centre. Its most notable structure is the Kremlin, a medieval fortress on the Moskva with Red Square along its eastern wall. The Lenin Mausoleum is nearby, and the Cathedral of St. Basil the Blessed is at the southern end of the square. Moscow is also home to the Bolshoi Theatre, Moscow State University, and many other institutions of higher education.
