Aryans were considered people who were said to speak an archaic Indo-European language and who were thought to have settled in prehistoric times in ancient Iran and the northern Indian subcontinent. The Nazis thought of them as the "Superior" race. Hitler justified his racism with Charles Darwin's research. According to Hitler's writings: "The stronger must dominate and not mate with the weaker, which would signify the sacrifice of its own higher nature. Only the born weakling can look upon this principle as cruel, and if he does so it is merely because he is of a feebler nature and narrower mind; for if such a law did not direct the process of evolution then the higher development of organic life would not be conceivable at all." It was, therefore, the Aryan's responsibilities to be dominant over other races and not mate with other races. Through the constitution, all German citizens had the Freedom of Speech, Assembly, and Press. The Aryans had right to certain jobs taken away from Jews by this "Aryan Law". The “Aryan Law” was a law the Nazis initiated near the beginning of Hitler’s rule to force Jews out of their jobs.
