What is the date of the United States Marine Corps' birthday?

The United States Marine Corps celebrates its birthday on November 10, 1775. This date is significant because it marks the formation of the Continental Marines at the recommendation of the Second Continental Congress, which aimed to create a naval infantry force for service with the fleet. The establishment of the Marine Corps is a pivotal moment in American military history, representing the beginning of a dedicated ground and amphibious force that has played a critical role in conflicts throughout U.S. history.

The other dates listed do not pertain to the founding of the Marine Corps. December 25, 1776, is notable for George Washington's crossing of the Delaware River, a key military event in the Revolutionary War. February 22, 1732, is the birthdate of George Washington, the first President of the United States and a pivotal figure in the American Revolution. March 1, 1781, marks the adoption of the Articles of Confederation, which was an important document in the early governance of the United States but unrelated to the Marine Corps' establishment. Therefore, the correct answer clearly highlights the Marine Corps' origin and its historical significance.
