How Did World War II Start?

World War II lasted from 1939 to 1945. The war was the direct result of the discontent that was felt worldwide on account of the economic depression, post World War I. The economic and political implications of the First World War made the people of nations like Germany and Italy lose faith in the governments. They voted into power dictators like Adolf Hitler and Benito Mussolini. These dictators initially worked to revive the insulted and wounded economies and thereafter, they embarked upon fulfilling their personal ambitions. This included territorial expansion and secret alliances to prove their stance as world powers.   
The immediate causes of World War II was the German invasion of Poland in 1939. Simultaneously, in the east, the Japanese attacked and began invading China and Manchuria and the various smaller colonies held by the United States of America, the British and the Dutch. In each of these situations, the attacks made were the result of vital decisions taken by the authoritarian dictators ruling the Axis Powers. Nevertheless, the invasion of Poland by Nazi Germany in 1939 and the resultant breach of the understanding of alliance that the Allies had signed with Germany. The secret alliances were then annulled and the animosity increased between the Allied and Axis powers and the result was World War II.

World War 2 Started back in 1914 and ended in 1945. It all started with Hitler and the Nazis Faking a Polish attack On Germany's Radio station.

The World War 2 is the most devastating and horrific event in the human history. Its main reasons lie with the European states of United Kingdom & France, who did not agree on most of the their policies on Germany. After the 1st war, Germany had been reduced to a broken state by the victors, who in post-war time were unsatisfied with their gains which included Japan & Italy. The formation of the League of Nations meant that the countries were depending more on their diplomacy to finding a safe and anti-war policies for settling their disputes.
With the rise in Fascism in Italy, it was clear that this movement would move on to other countries, which at that time was called as the only true Anti-Communism faction. Soon Adolf Hitler started preaching fascism in Germany who at that time was not well known. He promised the German people more land to live and that he would dissolve at treaties with the European nations. When in 1930 depression hit Germany, the national party members were not able to take any decisions which made the people move to the Nazi party for help. After many subsequent moves and series of deception in 1933, Hitler declared himself 'chancellor'. Italian dictator Mussolini supported him and in 1938, Hitler moved his armed forces to Austria for German Expansion.
