The largest Nazi extermination camp.

Auschwitz-Birkenau was the largest Nazi extermination and concentration camp, located in the Polish town of Oswiecim, 37 miles west of Cracow. One sixth of all Jews murdered by the Nazis were gassed at Auschwitz. In April 1940 SS chief Heinrich Himmler ordered the establishment of a new concentration camp in Oswiecim, a town located within the portion of Poland that was annexed to Germany at the beginning of World War II. The first Polish political prisoners arrived in Auschwitz in June 1940, and by March 1941 there were 10,900 prisoners, the majority of whom were Polish. Auschwitz soon became known as the most brutal of the Nazi concentration camps.
Building a Murder Complex
In March 1941 Himmler ordered a second, much larger section of the camp to be built right near the original camp. This site was to be used as an extermination camp and was named Birkenau, or Auschwitz II.
Eventually, Birkenau held the majority of prisoners in the Auschwitz complex, including Jews, Poles, Germans, and Gypsies. Furthermore, it maintained the most degrading and inhumane conditions--inclusive of the complex's gas chambers and crematoria. A third section, Auschwitz III, was constructed in nearby Monowitz, and consisted of a forced labor camp called Buna-Monowitz.
This complex incorporated 45 forced labor sub-camps. The name Buna was based on the Buna synthetic rubber factory on site, owned by I.G. Farben, Germany's largest chemical company. Most workers at this and other German-owned factories were Jewish inmates. The labor would push inmates to the point of total exhaustion, at which time new laborers replaced them.
Auschwitz was first run by camp commandant Rudolf Hess, and was guarded by a cruel regiment of the SS Death Head Units. The staff was assisted by several privileged prisoners who were given better food, conditions, and opportunity to survive, if they agreed to enforce the brutal order of the camp.
Auschwitz I and II were surrounded by electrically charged four-meter high barbed wire fences, guarded by SS men armed with machine guns and rifles. The two camps were further closed in by a series of guard posts located two thirds of a mile beyond the fences.
In March 1942, trains carrying Jews commenced arriving daily. In many instances, several trains would arrive on the same day, each carrying one thousand or more victims coming from the ghettos of Eastern Europe, as well as from Western and Southern European countries.
Throughout 1942, transports arrived from Poland, Slovakia, the Netherlands, Belgium, Yugoslavia, and Theresienstadt. Jews, as well as Gypsies, continued to arrive throughout 1943. Hungarian Jews were brought to Auschwitz in 1944, alongside Jews from the remaining Polish ghettos, yet to be liquidated.
