sep 1, 1939 - WWII BEGINS IN EUROPE WITH HITLER'S INVASION OF POLAND
Hitler used the ‘blitzkrieg’ strategy of waging
war to take over Poland, which he justified by
Lebensraum. Russia also invaded Poland, as
Russia and Germany’s Molotov-Ribbentrop
Pact said that the two countries would attack
Poland together and split the land. This
action finally prompted Britain and France to
declare war on Nazi Germany.
