1. The massacre of Jews during the Holocaust.

The Holocaust, during which six million Jews were systematically killed by the Nazis during World War II, had a significant impact on the creation of the state of Israel. The horrors of the Holocaust highlighted the need for a Jewish homeland where Jews could live in safety and security. This, along with international sympathy for the Jewish people in the aftermath of the Holocaust, helped to garner support for the establishment of a Jewish state in Palestine.
