Stutthof concentration camp near Gdansk (German Danzig), Poland was established on September 2, 1939, immediately after the Nazi invasion. It was the first place of incarceration and extermination set up in Poland, and the last liberated on May 9, 1945. It was originally intended to imprison the Polish intelligentsia. However, political enemies, antisocials, common criminals, Roma, Sinti, Jehova's Witnesses, homosexuals, and jews were soon added to the camp population. To become a political enemy or be considered antisocial, a Pole needed merely to refuse to sign an application for German nationality or just express opposition to the Nazi invasion or occupation. Some 110,000 men, women, and children were kept in the camp; about 65,000 died from slave labor, malnutrition, poor sanitation, or disease; or execution by shooting, hanging, beatings and torture, gas chamber, or phenol injection. From 1942, citizens from 28 other countries joined the incarcerated, and from 1944 jews were systematically murdered.  Link Map
