The world war is generally said to have begun on 1 September, 1939 with the invasion of Poland by Germany and after declarations of war on Germany by France and Britain to retaliate the attach that Germany maid on Poland. This eventualy formed two opposing military forces called the allies which was made up of the British Common Wealth, the Solviet Union and Amarica, also known as the "Big Three" and the Axis which contained Germany, Italy and Japan. People think the appeasement caused the war. appeasemant is when you give your countries power to anouthr country (in this case Germany) that you would be peasefull and woudn't go to war with them. This backfired and Germany still attacked to take total controle of other countries. I think that these conrties are foolish. they shouyld have never given Hilter that much power and if they never did appeasement the second world war might have never happened.
