What year is associated with the formation of the modern United States Marine Corps?

The year 1798 is significant because that marks the formal establishment of the United States Marine Corps as we know it today. While the origins of the Marine Corps date back to the Continental Marines formed during the American Revolutionary War in 1775, the U.S. Marine Corps was officially created as a distinct and functioning branch of the United States military with the passage of the Marine Corps Act on July 11, 1798. This act provided for the organization of the Marine Corps and outlined its structure, which included regulations for enlistment, retention, and officers' roles.

The Act of 1798 established the Corps as a part of the Navy, emphasizing its role in maritime operations and making it an integral component of the naval forces of the United States. This development laid the groundwork for the Marine Corps' evolution into a highly trained and versatile fighting force, capable of responding to various military needs both on land and at sea. Other options do not relate directly to the formal establishment and recognition of the Marine Corps as a separate entity within the U.S. military structure.
