Russia

note 1: largest country in the world in terms of area; despite its size, much of the country lacks the soil and climate (either too cold or too dry) for agriculture note 2: Russia's far east, particularly the Kamchatka Peninsula, lies along the Ring of Fire, which is a belt bordering the Pacific Ocean that contains about 75% of the world's volcanoes and up to 90% of the world's earthquakesnote 3: Mount El'brus is Europe's tallest peak; Lake Baikal, the deepest lake in the world, is estimated to hold one fifth of the world's fresh surface waternote 4: Kaliningrad oblast is an exclave annexed from Germany after World War II; its capital city of Kaliningrad -- formerly Koenigsberg -- is the only Baltic port in Russia that remains ice-free in the winter

Founded in the 12th century, the Principality of Muscovy emerged from over 200 years of Mongol domination (13th-15th centuries) and gradually conquered and absorbed surrounding principalities. In the early 17th century, a new ROMANOV dynasty continued this policy of expansion across Siberia to the Pacific. Under PETER I (1682-1725), hegemony was extended to the Baltic Sea and the country was renamed the Russian Empire. During the 19th century, more territorial acquisitions were made in Europe and Asia. Defeat in the Russo-Japanese War of 1904-05 contributed to the Revolution of 1905, which resulted in the formation of a parliament and other reforms. Devastating defeats and food shortages in World War I led to widespread rioting in the major cities of the Russian Empire and to the overthrow of the ROMANOV Dynasty in 1917. The communists under Vladimir LENIN seized power soon after and formed the Union of Soviet Socialist Republics (USSR). The brutal rule of Iosif STALIN (1928-53) strengthened communist control and Russian dominance of the Soviet Union at a cost of tens of millions of lives. After defeating Germany in World War II as part of an alliance with the US (1939-1945), the USSR expanded its territory and influence in Eastern Europe and emerged as a global power. The USSR was the principal US adversary during the Cold War (1947-1991). The Soviet economy and society stagnated in the decades following Stalin's rule, until General Secretary Mikhail GORBACHEV (1985-91) introduced glasnost (openness) and perestroika (restructuring) in an attempt to modernize communism. His initiatives inadvertently released political and economic forces that by December 1991 led to the dissolution of the USSR into Russia and 14 other independent states. In response to the ensuing turmoil during President Boris YELTSIN's term (1991-99), Russia shifted toward a centralized authoritarian state under President Vladimir PUTIN (2000-2008, 2012-present) in which the regime seeks to legitimize its rule through managed elections, populist appeals, a foreign policy focused on enhancing the country's geopolitical influence, and commodity-based economic growth. In 2014, Russia purported to annex Ukraine's Crimean Peninsula and occupied large portions of two eastern Ukrainian oblasts. In sporadic fighting over the next eight years, more than 14,000 civilians were killed or wounded as a result of the Russian invasion in eastern Ukraine. On 24 February 2022, Russia escalated its conflict with Ukraine by invading the country on several fronts in what has become the largest conventional military attack on a sovereign state in Europe since World War II. The invasion received near-universal international condemnation, and many countries imposed sanctions on Russia and supplied humanitarian and military aid to Ukraine. In September 2022, Russia unilaterally declared its annexation of four Ukrainian oblasts -- Donetsk, Kherson, Luhansk, and Zaporizhzhia -- even though none were fully under Russian control. The annexations remain unrecognized by the international community.

semi-presidential federation. Independence: 25 December 1991 (from the Soviet Union; Russian SFSR renamed Russian Federation); notable earlier dates: 1157 (Principality of Vladimir-Suzdal created); 16 January 1547 (Tsardom of Muscovy established); 22 October 1721 (Russian Empire proclaimed); 30 December 1922 (Soviet Union established)

natural resource-rich Eurasian economy; leading energy exporter to Europe and Asia; decreased oil export reliance; endemic corruption, Ukrainian invasion, and lack of green infrastructure limit investment and have led to sanctions
