Nazi persecution of Jews and others began with the Nuremberg Laws.
Explanation:
The Nuremberg Laws, enacted on September 15, 1935 were laws in Nazi Germany that restricted the rights of Jews and other "non-Aryans" and thus created a legal basis for Jewish racial discrimination. The purpose of the laws was to isolate Jews from "pure blood" Germans, both politically and socially.
The Nuremberg Laws classified people to whom both grandparents and both grandmothers were Germans as people of "German or related blood", while Jews who were three or four grandparents of Jews were classified as Jews. A person with one or two grandparents of Jewish descent was considered a hybrid, or a mixed blood person. These laws deprived Jews of German citizenship and prohibited marriage between Jews and other Germans.
The Nuremberg laws also prohibited sexual intercourse between persons defined as "Jews" and other Germans and prohibited "Jews" from participating in the social life of Germany.
All three nations were governed by monarchs, and the people wanted change. monarchy is when a place is governed by a king or/and queen. The people don't like it because the kings and the queens are unfair or bad. like the Russian monarchy turned into being communism monarchy.
