Why was war World War 2 fought?

World War II, often abbreviated as WWII or WW2, was a global conflict that lasted from 1939 to 1945 and involved most of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis. It has been said to be the deadliest conflict in human history, resulting in an estimated 70 to 85 million fatalities. These made up about 3 percent of the world's population at the time (est. 2.3 billion). The majority of the deaths were civilians, including the victims of the Holocaust, in which about six million Jews were exterminated by Nazi Germany.

The start of World War II is generally dated to September 1, 1939, when Germany invaded Poland. Other key events that led up to the war included the Manchurian Crisis of 1931, the Second Italo-Ethiopian War of 1935, the Spanish Civil War of 1936-1939, and the Anschluss of Austria by Nazi Germany in 1938.

The major participants in the war were the United Kingdom, the Soviet Union, the United States, China, and France. Other major belligerents included Germany, Italy, and Japan. The war started in Europe, with the German invasion of Poland, but eventually spread to other parts of the world, including Asia, Africa, and the Pacific Ocean.

The war ended in 1945, after the Allied victory over the Axis powers. The war had a profound impact on the world, leading to the formation of the United Nations, the decolonization of Africa and Asia, and the beginning of the Cold War between the United States and the Soviet Union.

Here are some of the key factors that led to World War II:

* The Treaty of Versailles: The Treaty of Versailles, which was signed after World War I, was very harsh on Germany. It left Germany feeling humiliated and resentful, and it paved the way for the rise of Adolf Hitler and the Nazi Party.

* The rise of fascism: Fascism is a political ideology that glorifies the nation and the state, and it often involves authoritarian rule and repression. Fascism was on the rise in Europe in the 1930s, and it was particularly strong in Germany, Italy, and Spain.

* The failure of the League of Nations: The League of Nations was an international organization that was established after World War I to prevent future wars. However, the League was unable to stop the rise of fascism and the outbreak of World War II.

* The Munich Agreement: The Munich Agreement was a 1938 agreement between Germany, Italy, France, and the United Kingdom that allowed Germany to annex the Sudetenland region of Czechoslovakia. The Munich Agreement was a major victory for Hitler, and it emboldened him to continue his aggressive expansion.

* The outbreak of war: World War II began on September 1, 1939, when Germany invaded Poland. The invasion of Poland was a violation of international law, and it led to the declaration of war by France and the United Kingdom on Germany.
