Aryan supremacy is the belief that the Aryan race, often characterized as a racial group of Indo-European descent, is superior to all other races. This ideology gained prominence in the early 20th century, particularly in Germany, as it was used to justify anti-Semitism and racial discrimination during the rise of the Nazi regime. The concept played a significant role in shaping policies and societal attitudes that contributed to the horrors of the Holocaust and the widespread oppression of various groups.
