Who was the totalitarian dictator of Germany during World War II?

Adolf Hitler was the totalitarian dictator of Germany during World War II, leading the country from 1933 until his death in 1945. He was the leader of the National Socialist German Workers’ Party (Nazi Party) and established a regime characterized by extreme authoritarianism, nationalism, militarism, and the suppression of political dissent. Hitler's beliefs were rooted in fascism, which emphasized a centralized, one-party state led by a dictatorial leader. His aggressive expansionist policies led to the invasion of numerous countries, ultimately igniting the global conflict known as World War II. His regime is also infamously associated with horrific atrocities, including the Holocaust, which targeted and exterminated six million Jews and millions of others deemed "undesirable." This historical context highlights why he is recognized as the totalitarian dictator characteristic of that era in Germany.
