So first the war was declared by Germany after they put German soldiers into Polish uniforms and let them attack a German Radio Station. Officially they just "defended" themselves after the "Polish attack". That was September 1st 1939. So you can see that Germany made that reason up. The real purpose of attacking Poland and so many other countries was to get more land and space for the German people. It became a World War when the rest of Europe got involved.
