how did ig farben company and auschwitz cooperate together
IG Farben The company played a role in German politics from its establishment. During the 1920s, it had ties to the liberal German People's Party[2] and was reviled by the Nazis who accused it of being an "international capitalist Jewish company."[2] The company later became a donor to the Nazi Party in the 1930s, and was a large government contractor after the Nazi takeover of Germany, providing significant material for the German war effort and becoming embroiled in regime policy including the use of slave labor at Farben's Buna Werke facility at Auschwitz, and the use of its minority-owned subsidiary's Zyklon B poison gas in the Holocaust. The company resumed operations after the Second World War, but in 1951 it was split into its four largest original constituent companies, which remain some of the world's largest chemical and pharmaceutical companies. These companies initially had the same owners, continued to operate as an informal cartel and played a major role in the West German Wirtschaftswunder. Following several later mergers the main successor companies are Agfa, BASF, Bayer and Sanofi.
