Days after Pearl Harbor, Nazi Germany declared war on America. But why did Hitler choose to draw the United States directly into the European conflict?

From Franklin D. Roosevelt’s perspective in the White House, democracy was under attack overseas and at home in mid-1941.

The 442nd Regimental Combat Team, a segregated Japanese American unit, is remembered today for its brave actions in World War II. Despite the odds, the 442nd’s actions distinguished them as the most decorated unit for its size and length of service in the history of the US military.

World War II was a global conflict involving nearly every country in the world. But who was on each side—and why?

When President Franklin Roosevelt created the War Refugee Board in January 1944, he tasked this new government agency with rescuing and providing relief for Jews and other groups facing Nazi persecution and murder in Europe. By that time, more than five million European Jews had already been murdered. The War Refugee Board staff used creativity and the near-certainty of Allied victory to aid hundreds of thousands of people in the final seventeen months of World War II.
