On June 6, 1944, the Allied powers launched D-Day, the largest seaborne invasion in history, and began the process of invading German-occupied Western Europe during World War II. Code-named "Operation Overlord," the invasion involved storming the beaches of Normandy, France.

The Normandy Invasion is often labeled as the beginning of the U.S.’s involvement in World War II in the European theater, but a lot of work the U.S. did built up to that date. The U.S. took a neutral stance on World War II until it became clear that neutrality was no longer an option.

Today, Normandy is a popular vacation destination due largely to the historic legacy it holds. From its bloody military past to the meaningful changes it symbolizes today, the Normandy Invasion remains a watershed moment that changed the course of world history as we know it.
