In September 1935 the Nuremberg Laws were enacted. The Reich Citizenship Law stated that only those of Germanic or related blood were defined as citizens. Thus Jews and other minority groups were stripped of their German citizenship. By the start of World War II in 1939, around 250,000 of Germany’s 437,000 Jews emigrated to the United States, Palestine, Great Britain, and other countries. 
Nazism brought together elements of antisemitism, racial hygiene, and eugenics, together with territorial expansionism with the goal of obtaining more Lebensraum (living space) for the Germanic people.
After the invasion of Poland in September 1939, Germany ordered the Polish leadership and intelligentsia should be destroyed. Approximately 65,000 civilians were killed by the end of 1939. In addition to leaders of Polish society, the Nazis killed Jews, prostitutes, Romani, and the mentally ill.
Auschwitz concentration camp (German: Konzentrationslager Auschwitz) was not one but a network of camps built and operated by the Third Reich in the Auschwitz area by Nazi Germany during World War II. It consisted of Auschwitz I (the original camp), Auschwitz II–Birkenau (a combination concentration/extermination camp), Auschwitz III–Monowitz (a labour camp to staff an IG Farben factory), and 45 satellite camps.
Auschwitz I was first constructed to hold Polish political prisoners, who began to arrive in May 1940.
During the construction, Local residents were evicted, including 1,200 people who lived around the barracks. From 1940 to 1941, 17,000 Polish and Jewish residents of the western districts of Oświęcim were expelled from places adjacent to the camp. The villages of Broszkowice, Babice, Brzezinka, Rajsko, Pławy, Harmęże, Bór, and Budy were also cleared.
The first prisoners (30 German criminal prisoners from the Sachsenhausen camp – located outside a Berlin) arrived in May 1940. The first transport of 728 Polish prisoners, which included 20 Jews, arrived on June 14, 1940, from the prison in Tarnów, Poland. By March 1941, 10,900 were imprisoned there, most of them Poles.
Construction began in October 1941 to ease congestion at the main camp. An initial contingent of 10,000 Soviet prisoners of war arrived at Auschwitz I in October 1941, but by March 1942 only 945 were still alive, and these were transferred to Birkenau, where most of them died from disease or starvation by May.
Himmler issued an order to send all Sinti and Roma (Gypsies) to concentration camps, including Auschwitz. A separate camp for Roma was set up at Auschwitz II-Birkenau known as the Zigeunerfamilienlager (Gypsy Family Camp). Approximately 23,000 Gypsies had been brought to Auschwitz by 1944, 20,000 of whom died there. One transport of 1,700 Polish Sinti and Roma was killed upon arrival, as they were suspected to be ill with spotted fever.
August 1944, the SS cleared the Gypsy camp. The population of 2,897 was then killed in the gas chambers. The murder of the Romani people in Romani language as the Porajmos (devouring)
IG Farben chose a site at Auschwitz to enable the making of Buna, a synthetic rubber.
A mini camp was built to house the workers for the plant, however due to shortages in raw materials the plant only opened in 1945. Shortly before it’s discovery by Soviet troops.
As well as IG Farben, companies such Krupp and Siemens-Schuckert, built factories with their own subcamps.
In memory of everyone affected by World War Two.
