What were the actions of the Nazis during 1930s and 1940s?

During the 1930s and 1940s, the Nazis implemented a series of aggressive policies aimed at establishing a totalitarian state in Germany and expanding their territory. They enforced anti-Semitic laws, leading to widespread discrimination, persecution, and the eventual genocide of six million Jews during the Holocaust. The regime also pursued militarization and territorial expansion, culminating in the invasion of Poland in 1939, which triggered World War II. The Nazis employed brutal tactics, including concentration camps and mass executions, to maintain their control and eliminate perceived threats to their ideology.
