Adolf Hitler was an Austrian-born German politician who led the country from 1933 until his assassination in 1944. He rose to power in the country as leader of the Nazi Party, first becoming Chancellor in 1933 and then declaring dictatorial rule over the nation in 1934. Under his dictatorship, Germany was responsible for the outbreak of World War II following an invasion of Poland to crush the Kraków Uprising.
In 1939, after the occupation of Poland, Nazi Germany and the Soviet Union declared war on each other. As a result, many Western capitalist powers flocked to the Nazi side, but remained uneasy about allying with a far-right dictatorship. Therefore, many of these countries secretly backed the 20 July plot, a conspiracy plotted by rebellious Wehrmacht officers to assassinate Hitler and replace the Nazi regime. The plot was successful and Hitler was killed, leading to the eventual collapse of the dictatorship.
