As @USMC celebrated its 250th birthday, the Department of State honored the Marines who have stood watch at our embassies and consulates worldwide. From 1775 to today, Marines embody "Semper Fidelis"—always faithful to protecting American diplomacy.

“The Marines and our diplomacy are tightly intertwined. Sometimes people have the mistaken idea that the strength represented by the Marines is an alternative to diplomacy. That’s wrong. Strength and diplomacy go together. They need each other.”—Secretary of State George P. Shultz.

Honoring #MarineCorps250: In 1898, at Minister Edwin Conger's request, the Marine guard at the U.S. Legation in Beijing became the first permanent legation guard established by the Department—a milestone in protecting American diplomacy. #USHistory #MarineCorps250

Continental Marines protected American diplomats crossing the Atlantic to secure alliances and negotiate treaties. When diplomat John Adams crossed the Atlantic in 1778 and they encountered an armed British ship, Adams joined the Marines on deck with musket in hand: “I ought to do my share of fighting.” #USHistory #MarineCorps250

The release of three chapters of Western Europe, 1977–1980 — out of nine chapters in total — represents a recent innovation in FRUS publication.  

This new approach allows the Office of the Historian to release declassified components of volumes as soon as they are cleared for publication, rather than waiting for the entire volume to be completed, ensuring that Department staff, researchers, and the American people have faster access to the official historical records.

The release of START I, 1989–1991 in 2025 marks another milestone for the Department.  It is the first FRUS publication (out of 33 planned volumes) documenting the George H.W. Bush administration.

National Security Policy, 1985–1988, Part 1, traces the evolution of President Ronald Reagan’s central objective to achieve peace through strength.  The documents illuminate his vision for the Strategic Defense Initiative (SDI) as a tool to protect America while also bringing the Soviets to the negotiating table.
