What were the events leading up to World War II and how did they impact the start of the Cold War?

An entirely new question about a related topic:
How did the policies of the United States and the Soviet Union during the Cold War contribute to the formation of alliances with other countries around the world?

To answer your first question, the events leading up to World War II were complex and involved various factors. Here are some key events that had a significant impact:

1. Treaty of Versailles: After World War I, the Treaty of Versailles imposed harsh terms on Germany, including territorial losses and heavy reparations. This created a sense of bitterness and hostility within Germany, contributing to the rise of Adolf Hitler and the Nazi Party.

2. Rise of Fascism: Fascist regimes, such as Benito Mussolini's Italy and Nazi Germany, gained power in the 1930s. Their aggressive expansionist policies, such as Italy's invasion of Ethiopia and Germany's annexation of Austria, created tension and fear among other nations.

3. Appeasement Policy: In an attempt to maintain peace, Western powers pursued a policy of appeasement towards Nazi Germany. This included allowing Hitler's annexation of Czechoslovakia's Sudetenland. However, this policy failed to prevent German aggression and ultimately emboldened Hitler.

4. Invasion of Poland: On September 1, 1939, Germany invaded Poland, marking the official start of World War II. This act led to declarations of war by France and the United Kingdom, triggering a global conflict.

As for your second question about the impact on the Cold War, the policies of the United States and the Soviet Union during the Cold War had a significant impact on the formation of alliances around the world. Here's an explanation of their respective policies and their contributions:

1. United States: The United States followed a policy of containment, aiming to prevent the spread of communism. This policy was outlined in the Truman Doctrine and further implemented through measures like the Marshall Plan and the formation of military alliances such as NATO (North Atlantic Treaty Organization). These actions were intended to strengthen alliances with countries that shared a common goal of resisting communism.

2. Soviet Union: The Soviet Union pursued a policy of expanding communism and influence through various means. This included supporting communist revolutions and insurgencies in different parts of the world, forming alliances such as the Warsaw Pact with Eastern European countries, and providing economic and military assistance to sympathetic nations.

The policies of the United States and the Soviet Union created a global competition for influence, resulting in the formation of alliances around the world. Countries aligned themselves with either the United States or the Soviet Union based on ideological, geopolitical, or economic considerations. These alliances were intended to provide security, economic aid, and support in the face of potential aggression or destabilization by the opposing superpower.
