The biggest powers in war met at the White House to discuss how to avoid more tension throughout East Asia. World Leaders wanted to avoid another World War and were worried because of the strong militarism in Japan. This is important because many large powers didn't want another war to emerge.
The nine countries that met were the United States, Japan, China, France, Britain, Netherlands, Italy, Belgium, and Portugal. The goal of these counties was to preserve peace throughout the world. This is important because without this meeting, conflict may have arose sooner or the world could've faced more struggles.
At the time of this meeting in 1921-1922, there was peace throughout the world and countries didn't want that to change. Women had recently gained the right to vote, many countries leaders were anti-war, such as the United States president, and leaders were promoting and educating on peace. This is important because this is what led to the meeting and the treaties gained from it.
The Washington Naval Conference led to 3 treaties being signed. They were the Four-Power Treaty, Five-Power Treaty, and the Nine-Power Treaty. This is significant because it allowed major countries to put their differences beside and work towards a common goal.
