1. The Munich Agreement (September 30, 1938):
This agreement was signed between Germany, Italy, Britain, and France to resolve the Sudetenland crisis. Germany was allowed to annex the Sudetenland region of Czechoslovakia, which had a predominantly German population.
2. The Pact of Steel (May 22, 1939):
This military alliance was signed between Germany and Italy. It committed both countries to provide mutual assistance in the event of war.
3. The German-Soviet Non-Aggression Pact (August 23, 1939):
This treaty was also known as the Molotov-Ribbentrop Pact. It was a non-aggression pact between Germany and the Soviet Union. The treaty included a secret protocol that divided Poland and the Baltic States between Germany and the Soviet Union.
It's worth noting that the treaties and alliances formed in the late 1930s contributed to the outbreak of World War II on September 1, 1939, when Germany invaded Poland. Britain and France declared war on Germany two days later, marking the beginning of the global conflict.
