There were various factors that led to the start of world war two. First of all, the rise of the Nazi party and Germany's quest for world control was a major factor in creating the tension that started the war. Around this same time, the Japanese began militarizing and tried conquering parts of China. Both of these countries created large amounts of tension and made the rest of the world on edge. Other countries began realizing that these two countries needed to be stopped, so they starting fighting back. Britain and France began to declare war on Germany once it began to invade Poland, which caused other allies to declare war on each other as well.

Finally, because of the treaties that ended World War 1, many countries were in debt and were tired of it, so they wanted to conquer other countries in order to solve their debt problem.
