Which events from world WWII could have inspired article 18?

The creation of Article 18 probably came about due to the persecution of Jews by the Nazis during World War II. Jews in German territories suffered due to numerous segregation laws. Later, Jews were sent to concentration camps, where many were tortured and executed. These actions resulted from a general mistrust and hatred among Germans toward the Jewish community. To prevent similar incidents from occurring in the future, the United Nations likely introduced Article 18. The article aimed to protect human rights while ensuring equality across all races and religions.

Nazism was the main event that led to human rights. Nazism didn't accept Jewish, homosexuals or disabled people and they persecuted them. Article 18 is all about human rights to freedom and religion.
