Volgograd, formerly Tsaritsyn (1589–1925) and Stalingrad (1925–1961), is the largest city and the administrative centre of Volgograd Oblast, Russia. The city lies on the western bank of the Volga, covering an area of 859.4 square kilometres (331.8 square miles), with a population of slightly over one million residents. Volgograd is the 16th-largest city by population size in Russia, the third-largest city of the Southern Federal District, and the fourth-largest city on the Volga.
The city was founded as the fortress of Tsaritsyn in 1589. By the 19th century, Tsaritsyn had become an important river-port and commercial centre, leading to its rapid population growth. In November 1917, at the start of the Russian Civil War, Tsaritsyn came under Bolshevik control. It fell briefly to the White Army in mid-1919 but returned to Bolshevik control in January 1920. In 1925, the city was renamed Stalingrad in honor of Joseph Stalin, who took part in defending the city against the White Army who had then ruled the country. During World War II, Axis forces attacked the city, leading to the Battle of Stalingrad, the largest and bloodiest battle in World War II, from which it received the title of Hero City. The Soviet victory at Stalingrad is widely held to be the turning point of World War II, leading to the destruction of the German army in the East. In 1961, Nikita Khrushchev's administration renamed the city to Volgograd as part of de-Stalinization.
