They have been waging war against us since before we were a country.
The Marine Corps got some of their traditions and even part of the Marine Hymn from the Barbary wars. "From the halls of Montezuma to the shores of Tripoli."
The war we waged against the Barbary pirates is where the name leatherneck came from. The heavy leather collar that is evident today in the dress blues saved Marine lives.
The Mameluke sword that Marine officers carry is from the sword presented to Lt. Presley O'Bannon.
Marine Corps history states that a sword of this type was presented to Marine First Lieutenant Presley O'Bannon by the Ottoman Empire viceroy, Prince Hamet, on December 8, 1805, during the First Barbary War, as a gesture of respect and praise for the Marines' actions at the Battle of Derne. Upon his return to the United States, the state of Virginiapresented him with a silver-hilted sword featuring an eaglehead hilt and a curved blade modeled after the original Mameluke sword given him by Hamet. Its blade is inscribed with his name and a commemoration of the Battle of Tripoli Harbor.
