What dictator started World War 2 in Europe?

Adolfo Hitler,the Fuhrër (chancellor) of Germany between 1932 until his death in 1945, was the leader of the Nazi party and built his campaign on the fact that he believed that the Aryan race was the dominant race of the world, and believed that homosexuals,Jews,gypsies,etc.,were less superior than them, and believed they should be exterminated. So, in 1939, Hitler began his conquest for world domination by invading Austria. Since Great Britian was allied with Austria at the time, they declared war on Germany. Thus, World War 2 began.
