History….
On September 1, 1939, the German army under Adolf Hitler launched an invasion of Poland that triggered the start of World War II (though by 1939 Japan and China were
already at war). The battle for Poland only lasted about a month before a Nazi victory. But the invasion plunged the world into a war that would continue for almost six years and claim the lives of tens of millions of people.
Today, 75 years later, Hitler is regarded as one of history's great villains. So it's easy to forget how slowly and reluctantly the worlds most powerful democracies mobilized to stop him. France and Britain did declare war on Germany two days after the invasion of Poland, but it would take them another eight months before they engaged in full-scale war with the Nazis. The United States wouldn't join the war against Hitler until December 1941, a full two years after the war began.
