View images taken at liberated Nazi concentration camps during World War II. When Adolf Hitler rose to power in Germany in the early 1930s, he began to establish thousands of camps to imprison political enemies and people considered inferior. Prisoners were starved, tortured, and killed. By 1941, killing centers were created specifically to murder the Jewish population. Nazi Germany was responsible for the deaths of 2 million non-Jewish Polish prisoners, 4 million Soviet POWs, and 6 million Jews. Nazis were also responsible for the deaths of thousands of gypsies, handicapped persons, and homosexuals. The full extent of the atrocities and genocide was not realized until Allied troops liberated the camps in 1945.
