The Origin of the Marine Corps Birthday
The Marine Corps was officially established on November 10, 1775, when the Second Continental Congress passed a resolution to form two battalions of Marines. These forces were created to serve as naval infantry during the American Revolutionary War, trained to fight both on land and at sea.
Although the Corps was briefly disbanded after the war, it was permanently reinstated in 1798. But it wasn’t until 1921 that the Marine Corps formally recognized its founding date as an annual tradition. Major General John A. Lejeune, the 13th Commandant of the Marine Corps, issued Marine Corps Order No. 47, officially designating November 10 as the Marine Corps Birthday.
Since then, Marines across the world have proudly celebrated this date every year — no matter where they are stationed.
Marine Corps Birthday 2025: Celebrating 250 Years of Service
In 2025, the United States Marine Corps marks its 250th birthday — a historic milestone that symbolizes two and a half centuries of courage, sacrifice, and honor.
This year’s celebrations are especially meaningful, as the Marine Corps reflects on its long-standing legacy and the generations of Marines who have fought for the nation’s freedom. From battlefields like Iwo Jima and Belleau Wood to modern missions in the Middle East and beyond, Marines have remained faithful to their motto: “Semper Fidelis” — Always Faithful.
Across the United States and around the globe, Marine units, veterans, and their families are commemorating the day with ceremonies, parades, and special gatherings.
How the Marine Corps Birthday Is Celebrated
The Marine Corps Birthday is not just a date on the calendar — it’s a deeply cherished event filled with tradition and respect. Every year, celebrations include ceremonies, formal dinners, and moments of remembrance.
The Marine Corps Birthday Ball
The most famous celebration is the Marine Corps Birthday Ball, a formal event held at Marine bases and embassies worldwide. It includes speeches, dancing, and toasts, all highlighting the history and values of the Corps. The Commandant of the Marine Corps delivers a message, honoring both active-duty Marines and veterans.
The Cake-Cutting Ceremony
One of the most symbolic traditions is the cake-cutting ceremony. Using a ceremonial sword, Marines cut a birthday cake — the first slice goes to the guest of honor, and the second is passed from the oldest Marine present to the youngest. This act symbolizes the passing of knowledge, tradition, and duty from one generation to the next.
Commandant’s Birthday Message
Every year, the Commandant of the Marine Corps releases a birthday message to all Marines, reflecting on the Corps’ heritage and future goals. The message is played at ceremonies and shared across Marine bases, ensuring every Marine feels connected to the greater brotherhood.
Where Marines Celebrate
No matter where they are in the world, Marines find a way to celebrate their birthday. From grand ballroom events in the United States to modest gatherings in combat zones, the Marine Corps Birthday unites Marines across every rank and region.
Some of the most recognized celebrations in 2025 include:

Why the Marine Corps Birthday Matters
For Marines, November 10 is not just a day of pride — it’s a sacred tradition. It reminds them of the sacrifices made by those who came before and the duty carried by those who serve today.
The Marine Corps Birthday honors the spirit that defines the Corps: Honor, Courage, and Commitment. These core values guide every Marine’s actions, from boot camp to the battlefield.
It’s also a day to remember the fallen — those who gave their lives in service to the United States. During ceremonies, moments of silence are observed to pay respect to the men and women who made the ultimate sacrifice.
The Role of the Marine Corps Today
In 2025, the Marine Corps continues to be one of the world’s most respected military organizations. With more than 175,000 active-duty Marines and over 30,000 reservists, it serves as America’s rapid-response force — ready to deploy anywhere in the world at a moment’s notice.
The Marines are engaged in diverse missions, including:

- Joint military exercises with allied nations.
- Security and peacekeeping efforts abroad.

Despite the evolving landscape of warfare, the Marine Corps remains anchored in tradition, discipline, and adaptability — values that have defined it for 250 years.
The Meaning of “Semper Fidelis”
Every Marine lives by the motto “Semper Fidelis,” Latin for “Always Faithful.” It represents a lifelong commitment — to the Corps, to their fellow Marines, and to the nation they serve.
This spirit of loyalty extends far beyond active duty. Veterans continue to uphold the same values in civilian life, strengthening communities and inspiring future generations. The Marine Corps Birthday serves as a moment for all Marines, past and present, to renew their promise to remain faithful — no matter where life takes them.
