had several manufacturing facilities and railroad workshops and an engine-house. Growth continued with the discovery of gold and the arrival of a railroad in 1895. In the Russian Empire, Krasnoyarsk was one of the places to which political exiles were banished. For example, eight Decembrists were deported from St. Petersburg to Krasnoyarsk after the failure of the revolt. In the aftermath of the Russian Revolution of 1917, during the Russian Civil War, Siberia east of Omsk was controlled by white forces under Alexander Kolchak, who in December 1919 retreated east to Irkutsk and the Bolsheviks took control of the city. On a plateau 7 km outside of town was a prisoner of war camp with 13,000 German and Austrian troops. Elsa Brändström of the Swedish Red Cross spent almost a year there from July 1919 until May 1920. During the periods of centralized planning (Five Year Plans) numerous large plants and factories were constructed in Krasnoyarsk: Sibtyazhmash, the dock yard, the paper factory, the hydroelectric power station (now the fifth largest in the world and the second in Russia), and the river port. In 1934, Krasnoyarsk Krai was formed, with Krasnoyarsk as its administrative center. During Stalinist times, Krasnoyarsk was a major center of the gulag system. The most important labor camp was the Kraslag or Krasnoyarsky ITL (1938-c.1960) with the two units located in Kansk and Reshyoty. In the city of Krasnoyarsk itself, the Yeniseylag or Yeniseysky ITL labor camp was prominent as well during World War II (c. 1940–41). During World War II, dozens of factories were evacuated from Ukraine and Western Russia to Krasnoyarsk and nearby towns, stimulating the industrial growth of the city. After the war additional large plants were constructed: the aluminum plant, the metallurgic plant, the plant of base metals and many others. In the late 1970s, the Soviet Union began constructing a phased array radar station at Abalakova, near Krasnoyarsk, which violated the ABM Treaty. Beginning in 1983, the United States demanded its removal, until the Soviet Union admitted the radar station was a violation in 1989. Equipment was slowly removed from the site and by 1992 it was officially declared to be dismantled, though the equipment from the site was likely relocated to a new site near Komsomolsk-na-Amure. Krasnoyarsk was also a home to Krasnoyarsk Northeast air base, which was turned into living blocks after the dissolution of the Soviet Union. After
