The Jewish Holocaust, also known as the Shoah, was a systematic genocide of the Jewish people by Nazi Germany and its collaborators during World War II. The Holocaust lasted from 1933 to 1945, with the peak of the genocide occurring between 1941 and 1945. Adolf Hitler, who was the leader of Nazi Germany during this time, implemented a policy of extermination against the Jewish people as well as other minority groups deemed undesirable by the Nazi regime. Under Hitler's leadership, millions of Jews were rounded up, transported to concentration camps, and systematically murdered in gas chambers or through forced labor and starvation. The Holocaust is widely regarded as one of the darkest periods in human history, with an estimated six million Jews and millions of other people, including Romani people, people with disabilities, and LGBTQ+ individuals, murdered by the Nazis and their collaborators. The Holocaust has had a profound impact on Jewish communities worldwide, and efforts to remember the victims and prevent future genocides continue to this day.
