The Marine Corps adopted Semper
Fidelis as its official motto in 1883 (Semper
Fidelis is also the title of the official musical March of
the Marine Corps). Translated
from Latin, Semper Fidelis means "Always Faithful."
U.S. Marines use an abbreviated verbal version, "Semper
Fi," to voice loyalty and commitment to their Marine
mottos of the Marine Corps were (1) To
the Shores of Tripoli, adopted in 1805; (2) Fortitude,
adopted in 1812; (3) From
the Halls of Montezuma to the Shores of Tripoli, adopted in
1848; and (4) By Sea and
by Land, adopted in the 1850's.
