Adolf Hitler was a German politician and leader of the National Socialist German Workers' Party (Nazi Party). He rose to power as Chancellor of Germany in 1933 and later Führer in 1934. His aggressive expansionist policies led to the outbreak of World War II and the implementation of the Holocaust, which resulted in the genocide of six million Jews and millions of others deemed undesirable. Hitler's regime was marked by totalitarian control, propaganda, and militarism. His ideologies of Aryan supremacy and anti-Semitism had devastating effects on Europe and the world. Hitler's actions and the consequences of his rule continue to be studied and remembered as a cautionary tale of hatred and intolerance.
