Question

one important cause of the uprising world war2?

Answer 1

Among the causes of World War II were Italian fascism in the 1920s, Japanese militarismand invasions of China in the 1930s, and especially the political takeover in 1933 of Germany by Hitler and his Nazi Party and its aggressive foreign policy. The immediate cause was Britain and France declaring war on Germany after it invaded Poland in September 1939.

Answer 2

Treaty of Versailles
The Treaty of Versailles ended World War I between Germany and the Allied Powers. Because Germany had lost the war, the treaty was very harsh against Germany. Germany was forced to "accept the responsibility" of the war damages suffered by the Allies. The treaty required that Germany pay a huge sum of money called reparations. The problem with the treaty is that it left the German economy in ruins. People were starving and the government was in chaos.

Japanese Expansion
In the period before World War II, Japan was growing rapidly. However, as an island nation, they did not have the land or the natural resources to sustain their growth. Japan began to look to grow their empire in order to gain new resources. They invaded Manchuria in 1931 and China in 1937. 

Hitler and the Nazi Party
In Germany, Adolf Hitler and the Nazi Party rose to power. The Germans were desperate for someone to turn around their economy and restore their national pride. Hitler offered them hope. In 1934, Hitler was proclaimed the "Fuhrer" (leader) and became dictator of Germany.

 Hitler resented the restrictions put on Germany by the Treaty of Versailles. While talking about peace, Hitler began to rearm Germany. He allied Germany with Mussolini and Italy. Then Hitler looked to restore Germany to power by expanding his empire. He first took over Austria in 1938. When the League of Nations did nothing to stop him, Hitler became bolder and took over Czechoslovakia in 1939. 

Great Depression
The period before World War II was a time of great economic suffering throughout the world called the Great Depression. Many people were out of work and struggling to survive. This created unstable governments and worldwide turmoil that helped lead to World War II.
