What are the causes of the world war II ?

there are numerous reasons for the start of world war ll

Explanation:

They include: the impact of the Treaty of Versailles on the start of the first world war, not to mention the worldwide economic depression that was being faced at the time as well, as well as the failure of appeasement that had just occured, and the rise of militarism that was growing rapidly in Germany and Japan, and finally the failure of the League of Nations had the most impact on the start of the new war.

Some causes of World War II were the aggressive actions of Germany, Japan, and Italy and the German resentment caused by the Treaty of Versailles but world war 1 was the main cause.

Explanation:

World War I was the main cause of World War II, for several reasons. First, the German people reacted very badly to the German surrender, which many regarded as a backstab, and even more so to the Versailles treaty, which they were forced to sign without negotiation. The treaty made them take complete blame for the war, demanded onerous reparation payments, and severely limited the size of the German military. Therefore these were perceived as humiliating conditions. Almost as soon as the war was over, demagogues, notably Adolph Hitler, were able to use the circumstances of the defeat to blame Jews, advocate for fighting back to avenge the German people and eventually to seize political power.
