WWII impacting the need for stronger guidelines for Human Rights

The Holocaust was one of the first occurrences of outright hatred against a given group of people after the creation of the United Nations Charter for Human Rights. During the Holocaust, members of Nazi Germany invaded several European countries and exterminated millions of Jewish people simply because of their religion. Additionally, hundreds of thousands of gypsies, homosexuals, and people who identified with different social groups were persecuted and killed. This was obviously a gross breach of the simplest form of human rights. Post WWII it became increasingly evident that a much stronger body and incentive was needed to compel countries to abide by mutual standards of human rights to ensure the safety and quality of life of their citizens and to prevent any further genocides from occurring.
