What fascist order is the first signal of oppression for the jewish community

Historically, when talking about the persecution of the Jewish people we have to go back to hundreds of years ago, as they were chased in crusades and wars, as they were harassed, for example, in the First Crusade (1096).

In spite of the existance of anti-Semitism before the Nazi period, if we are talking about modern fascist orders, the anti-Semitism politics by Hitler and the Nazi German Party can be considered the most important modern oppression system for Jewish people.
