Explicate the Causes and Effects of World War II.
The causes of World War II primarily focused on European politics and include the resurgence of militarism, the system of alliances, dictatorship, and the aggression of Germany in Europe. Central to these causes was Germany's invasion of Poland in 1939, which lead to Britain and France declaring war on Germany and thus the beginning of the Second World War. The effects of the war were immense and included the deaths of tens of millions of people, the destruction of entire cities, and the breakdown of the post-WWI order. The war also led to the rise of the United States as a superpower, the spread of communism, the foundation of the United Nations, and the introduction of nuclear weapons.
