Did you ever wonder why the Marine Corps is part of the Department of the Navy?
Historically, marines serve as a navy’s ground troops. In fact, the word "marine"is the French word for sea, which may be why the French military historically called English troops — who all had to arrive by sea — "marines."
Back in the day, there wasn’t much difference between a sailor and a soldier on a ship. After all, most sea battles ended with the ships tangled together and the crews fighting each other hand to hand. So, if you were on a ship, you had to be able to fight. But you also had to be able to fight once your ship got where it was going.
Italy was the first country to use specially trained sailors as naval infantry. Back in the 1200s, the chief magistrate of Venice put 10 companies of specialized troops on a bunch of ships and sent them off to conquer Byzantium in present-day Greece. That went well for the Italians, so they decided that having marines was a good idea and kept them around, later calling them "sea infantry."
The idea of marines eventually caught on with other naval powers. The Spanish marine corps was founded in 1537 and is the oldest still-active marine corps in the world, while the Netherlands marine corps, founded in 1665, is the second-oldest. But, even today, marines in most countries are specially trained sailors who are part of the navy.
The British Royal Marines, which is what the U.S. Marine Corps was modeled on, were probably the first naval infantry to not actually be sailors. During the 1600-1700s, marine regiments would be formed by taking soldiers from the British Army, and disbanded when they weren’t needed. This practice continued until 1755, when England’s parliament made the Corps of Royal Marines permanent.
When the Continental Marines were founded in 1775, the Continental Congress recognized the importance "that particular care be taken, that no persons be appointed to office, or enlisted into said Battalions, but such as are good seamen, or so acquainted with maritime affairs as to be able to serve to advantage by sea when required."
So, maritime knowledge has always been a critical part of being a marine, but the U.S. Marine Corps hasn’t always been part of the U.S. Navy.
Until 1834, the Marines were an independent service. President Andrew Jackson wanted to make the Corps part of the Army. However, the Marine Corps commandant at the time, Archibald Henderson, had proven that Marines were important in landing party operations, not just ship-to-ship battles, so Congress decided to put the Navy and Marine Corps into one department, forever linking these two "sister services."
Given my extensive background in military history and organizational structures, let's delve into the fascinating evolution of the Marine Corps and its historical connection to the Department of the Navy.
The concept of marines as naval infantry has deep roots, dating back to Italy in the 1200s. The Venetians, under the chief magistrate, deployed specialized troops on ships to conquer Byzantium. This innovative approach proved successful, leading to the establishment of marines, or "sea infantry." Spain followed suit in 1537, founding the oldest active marine corps, while the Netherlands established its marine corps in 1665.
The British Royal Marines, serving as a model for the U.S. Marine Corps, broke away from the traditional sailor mold. Unlike their predecessors, the Royal Marines were formed from soldiers of the British Army during the 1600-1700s. This practice persisted until 1755 when the Corps of Royal Marines became a permanent fixture under England's parliament.
When the Continental Marines emerged in 1775, the Continental Congress emphasized the importance of recruiting individuals with maritime expertise. This underscores the historical link between marines and maritime affairs, a critical aspect of their training and role.
Interestingly, until 1834, the U.S. Marine Corps operated independently. President Andrew Jackson sought to integrate the Marines into the Army, but Marine Corps commandant Archibald Henderson demonstrated their unique capabilities in landing party operations. Recognizing this, Congress decided in 1834 to unite the Navy and Marine Corps under one department, solidifying the enduring connection between these "sister services."
This historical journey not only highlights the strategic importance of marines as naval infantry but also underscores the intertwined relationship between the U.S. Marine Corps and the Department of the Navy. It's a testament to the adaptability and evolving roles of military forces throughout history.
