90 years ago today, on September 15, 1935 (August 18, 1935 in the lunar calendar), the German Bloodline and Honor Protection Law was promulgated. In 1920, Hitler put forward anti-Semitic ideas in the Nazi Party's 25-point program. After Hitler came to power, persecution of Jews became a national policy. In April 1933, Jews were prohibited from engaging in business, doctor and lawyer professions, and Jews were prohibited from working in the state department. On September 15, 1935, the "Protection of German Origin and Honor Law", also known as the Nuremberg Law, was promulgated. On the grounds of protecting German origin and honor, Jews were prohibited from marrying and having extramarital relations with citizens of Germany or their own origin, and Jews were prohibited from raising the German flag or showing colors symbolizing Germany. The supplementary decree issued in November also stipulates that Jews are not allowed to become German citizens, exercise their right to vote, and hold public office. From 1935 to 1938, the Nazis enacted a series of anti-Semitic decrees. After 1938, Jews were brutally persecuted and collectively expelled. On November 9, 1938, Goebbels organized a massacre. It is called the "National Night of Breaking Windows". On this day, Jewish shops were looted, churches were destroyed, dozens of people were killed, and more than 20,000 Jews were imprisoned in concentration camps. The subsequent ban on opening businesses was extended to all Jewish doctors, lawyers, industrialists and craftsmen, and Jews were prohibited from entering public schools and universities, as well as many public places, and the purchase of cars and other valuables was prohibited. Many Jews fled their homeland. After Germany launched World War II, it continued to carry out the Holocaust against Jews in the occupied areas. The "Final Settlement" began in the autumn of 1941, sending Jews from across Europe to extermination camps in Poland, killing between 4 and 6 million people.
