The Third Reich refers to the period of Nazi Germany from 1933 to 1945, when the country was under the dictatorship of Adolf Hitler and the National Socialist German Workers' Party (Nazi Party). This regime aimed to establish a totalitarian state, promoting extreme nationalism, militarism, and the idea of Aryan racial superiority. During the Third Reich, Germany expanded its territory through aggressive military campaigns, leading to the outbreak of World War II. The regime is also infamous for its role in the Holocaust, where millions of Jews and other minority groups were systematically persecuted and murdered.
