Answer:
The concept of the master Aryan race was a pseudoscientific idea in Nazi ideology that deemed the putative "Aryan race" as the pinnacle of human racial hierarchy. The Nazis recognized the Germanic people as the master race and implemented several policies to improve and maintain the Germanic-Nordic ubermenschen Aryan "master race," including the practice of eugenics. The Aryan certificate was an official document that certified its owner as an Aryan, and it could be obtained by citizens of other countries. The Aryan certificate stated that Aryans were superior to other races.
The Aryan Master Race conceived by Adolf Hitler and the other Nazis graded humans on a scale of pure Aryans to non-Aryans, who were viewed as subhumans. At the top of the scale of pure Aryans were Germans and other Germanic and Northern European peoples, including the Dutch, Scandinavians, and the English. Latins were held to be somewhat inferior but were tolerated, and the French were thought to have a suitable admixture of Germanic blood. The feeling that Germans were the Aryan Herrenvolk (Aryan master race) was widely spread among the German public through Nazi propaganda and among Nazi officials throughout the ranks.
The Aryan race is an obsolete historical race concept that emerged in the late-19th century to describe people of Proto-Indo-European heritage as a racial grouping, which gained prominence in Nazi Germany during World War II with the use of eugenics to sustain the idea of an übermensch. In Nazi Germany, the “Aryan race” was a grouping of Caucasian people with defined facial features, longer chins, slightly prominent eyes of blue to green color, with the highlight given to light hair, mainly blond, where the peoples of northern Europe were used as a reference. The Nazis claimed that the Germanic peoples specifically represented a southern branch of the Aryan-Nordic population. The Nazis considered that the Nordic race was the most prominent race of the German people, but that there were other sub-races that were commonly found amongst the German people such as the Alpine race.
