in June 1919 the White Armed Forces of South Russia, under the command of General Denikin, captured Tsaritsyn, and held it until January 1920. The fighting from July 1918 to January 1920 became known as the Battle for Tsaritsyn. Stalingrad On April 10, 1925, the city was renamed Stalingrad, in honor of Joseph Stalin, General Secretary of the Communist Party. This was officially to recognize the city and Stalin's role in its defense against the Whites between 1918 and 1920. Once the Soviets established control, ethnic and religious minorities were targeted. The only Jewish school in the area was closed down in 1926. In 1928, a campaign was launched by the Regional Executive Council to close down the synagogue in Stalingrad. Due to local pushback, they were not successful until 1929, when the council convened a Special Commission. The Commission convinced local municipal powers that the building was in need of major repairs, was unsafe and much too small for the over 800 worshippers who regularly showed up for high holidays. In 1931, the German settlement-colony Old Sarepta (founded in 1765) became a district of Stalingrad. Renamed Krasnoarmeysky Rayon (or "Red Army District"), it was the largest area of the city. The first higher education institute was opened in 1930. A year later, the Stalingrad Industrial Pedagogical Institute, now Volgograd State Pedagogical University, was opened. Under Stalin, the city became a center of heavy industry and transshipment by rail and river. Battle of Stalingrad During World War II, German and Axis forces attacked the city, and in 1942 it was the site of one of the pivotal battles of the war. The Battle of Stalingrad was the deadliest single battle in the history of warfare (casualties estimates vary between 1,250,000 and 1,798,619). The battle began on August 23, 1942, and on the same day, the city suffered heavy aerial bombardment that reduced most of it to rubble. Martial law had already been declared in the city on July 14. By September, the fighting reached the city center. The fighting was of unprecedented intensity; the city's central railway station changed hands thirteen times, and the Mamayev Kurgan (one of the highest points of the city) was captured and recaptured eight times. By early November, the German forces controlled 90 percent of the city and had cornered the Soviets in two narrow pockets, but they were unable to eliminate the last pockets
