by Adolf Hitler was the dictator of Germany from 1933 to 1945. He was the leader of the Nazi Party, which was responsible for the Holocaust, the genocide of six million Jews and millions of other people. Hitler also started World War II, which was the deadliest conflict in human history.
World War II was a global war that lasted from 1939 to 1945. The war involved the vast majority of the world's countries—including all of the great powers—eventually forming two opposing military alliances: the Allies and the Axis. In a state of total war, directly involving more than 100 million personnel from more than 30 countries, the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. World War II was the deadliest conflict in human history, marked by 50 to 85 million fatalities, most of whom were civilians in the Soviet Union and China. Tens of millions of people died due to genocides (including the Holocaust), premeditated death from starvation, massacres, and disease. Aircraft played a major role in the conflict, including in the strategic bombing of population centers, the development of nuclear weapons, and the only two uses of such in war.
Hitler and World War II are two of the most important events in modern history. They had a profound impact on the world, and their legacy continues to be felt today.
