On this day in history, Nazi leader Adolf Hitler violates the Treaty of Versailles and the Locarno Pact by sending German military forces into the Rhineland, a demilitarized zone along the Rhine River in western Germany.
In 1935, Hitler unilaterally canceled the military clauses of the treaty and in March 1936 denounced the Locarno Pact and began remilitarizing of the Rhineland. Two years later, Nazi Germany burst out of its territories, absorbing Austria and portions of Czechoslovakia.
In 1939, Hitler invaded Poland, leading to the outbreak of World War II in Europe.
On this day, during the battle for Iwo Jima, U.S. Marines raise the American flag atop Mt. Suribachi, the highest point on the island of Iwo Jima and a key strategic point.
Later, Marine commanders decide to raise a second, larger flag, an event which an Associated Press photographer captured on film. The resulting photograph became a defining image of the war.
