At the very beginning of the war, just about every country started to involve itself in the uproar. However, when everything started, people across the globe were collectively neutral. It was less about taking sides and more about trying to find peace so that countries could find a baseline level of harmony. That said, World War II transpired for quite a lengthy period of time, and as the war progressed, countries started splitting into opposing sides of war.
This split transformed into the Axis Powers and the Allied Powers. During the second World War, the main division was between the United States of America and Japan. The United States was on the side of the Allied Powers, as were China, the Soviet Union, and the United Kingdom. They were acknowledged as collectively being the Big Four Allied Powers. On the other side of the spectrum was the Axis Powers.
The countries that were recognized as being Allied Powers in World War II include...
- New Zealand
- South Africa
- The Soviet Union
- The United Kingdom
- The United States of America
The main players in the Axis Powers were the Empire of Japan, the Kingdom of Italy, and Germany. The three main parties that comprised the Axis Powers entered World War II under the Tripartite Treaty. Four other countries ultimately signed the Tripartite Treaty on their own terms. Bulgaria co-signed the document on March 1, 1941, and the three European countries of Hungary, Romania, and Slovakia signed the previous year. Hungary signed the treaty on November 20, 1940, and Romania signed three days later. The following day, Slovakia signed the treaty on November 24, 1940.
