Answer: The Nazi Party was founded in 1920. It sought to woo German workers away from socialism and communism and commit them to its anti-Semitic and anti-Marxist ideology. This allowed the Nazis to prevent workers from organizing any opposition. All existing political parties were banned. From mid-July 1933 onwards, Germany was a single-party state. Cultural and scientific ‘cleansings’ were carried out as well. According to the Nazis, everything ‘un-German' had to disappear.
