The stage is set for World War II on this episode of This Day In History.

On this episode of This Day In History, Tony and Armand take us back in time to discuss the beginnings of World War II.

In 1939, an extraordinary chain of events set the stage for the second world war. On this day, the European phase of World War II began when Nazi Germany and Slovakia invaded Poland, and Adolf Hitler signed an order to begin the systematic euthanasia of the mentally ill and disabled. Elsewhere, General George C. Marshall became the Chief of Staff of the United States Army and Swiss Parliament elects Henri Guisan to head the Swiss Armed Forces.

Plus, 1969 sees a coup in Libya bring Muammar Gaddafi to power, Korean Air Lines Flight 007 is shot down by a Soviet Union jet fighter in 1983, and Lily Tomlin is born on this day in 1939.
