Which date marks the origin of the Marine Corps?

The date that marks the origin of the Marine Corps is significant because it was on November 10, 1775, that the Second Continental Congress resolved to establish two battalions of Marines. This decision came as a response to the need for a dedicated naval infantry force that could operate effectively aboard ships and carry out amphibious operations, which were essential for the Revolutionary War efforts. The establishment of the Marine Corps on this date laid the foundation for what would become a premier fighting force known for its adaptability, rigor, and commitment to mission success.

The other dates listed are historically relevant to the United States but do not correspond to the establishment of the Marine Corps. July 4, 1776, marks the Declaration of Independence, January 1, 1781, is significant for various military operations during the war, and September 12, 1783, relates to the conclusion of the Revolutionary War. Each of these events is important in American history, but they did not directly involve the formation of the Marine Corps as an entity.
