Nazi Germany refers to the period from 1933 to 1945 when the National Socialist German Workers' Party, led by Adolf Hitler, ruled Germany. This regime was characterized by totalitarian control, aggressive nationalism, and the promotion of an ideology centered on Aryan supremacy. The government implemented policies that led to the persecution of various groups, including Jews, Romani people, and political dissidents. During this time, Germany expanded its territory through military aggression, leading to the outbreak of World War II in 1939. The war resulted in widespread devastation across Europe and the eventual defeat of Nazi Germany in 1945, which led to the division of the country and the establishment of a democratic government in West Germany.
