Semper fidelis (Latin pronunciation:[ˈsɛmpɛrfɪˈdeːlɪs]) is aLatin phrase that means "always faithful" or "always loyal" (Fidelis or Fidelity). It is themotto of theUnited States Marine Corps, usually shortened toSemper Fi. It is also in use as a motto for towns, families, schools, and other military units.
It is thought that it originated from the phrase that the senators of ancient Rome declaimed at the end of their intervention.
The earliest definitively recorded use ofsemper fidelis is as the motto of the French town ofAbbeville since 1369. It has also been used by other towns, and is recorded as the motto of various European families since the 16th century, and possibly since the 13th century or earlier. Records show many families in England, France and Ireland using this motto.
The earliest recorded use ofsemper fidelis by a military unit is by the Duke of Beaufort's Regiment of Foot, raised in south-western England in 1685. This is apparently linked to its use as a motto by the city ofExeter no later than 1660. Subsequently, a variety of military organizations adopted the motto.
This phrase was used in Europe, at least in Great Britain, Ireland and France and probably in other countries as well. A more recent adoption is bySenatorJoe Doyle, in arms granted by theChief Herald of Ireland in 1999.[citation needed]
Bernard Burke in 1884[1] listed many notable families inGreat Britain andIreland using the motto "Semper fidelis" in theircoats of arms. They include:
Burke's full list of families using the motto was: Booker, Barbeson, Bonner, Broadmead, Carney, Chesterman, Dick, Dickins, Duffield, Edge, Formby, Frisby, Garrett, Haslett, Hill, Houlton, Kearney, Lynch, Lund, Marriott, Nicholls, Onslow, Pollexfen,Smith, Steele, Steehler, Steuart, Stirling and Wilcoxon. A large portion of these families were Irish or Scottish.
Chassant and Tausin (1878, p. 647)[7] list the following French families as using it: D'Arbaud of Jonques, De Bréonis, Chevalier of Pontis, Du Golinot of Mauny, De Coynart, De Genibrouse of Gastelpers, Macar of the Province of Liege, Milet of Mureau, Navoir of Ponzac, De Piomelles, De Poussois, de Lamarzelle, De Reymons, Henry de Lolière and De Rozerou of Mos.
The city ofAbbeville inFrance is recorded by 19th century sources (such as Chassant and Taussin, 1878) as using the motto "Semper fidelis," and recent sources[8] state that the city was accorded this motto byCharles V, byletters patent of 19 June 1369, issued atVincennes. This would make it the earliest recorded user of the motto among cities. However both Louandre (1834, p. 169)[9] and the city's current official website[10] give the motto simply as "Fidelis", and Sanson (1646, p. 15)[11] claimed that even this was not part of Charles's original grant, but was added later, sometime in the 14th to 17th centuries.

In 1658,Pope Alexander VII bestowed the heraldic motto "Leopolis semper fidelis" onLviv (then Lwów, part of theKingdom of Poland).[12] In 1936, the motto "Semper fidelis" was applied again to the coat of arms of the city (then part of theSecond Polish Republic).[13]
Today, inPoland, the motto is referenced mainly in connection with thePolish-Ukrainian War of 1919 following the collapse ofAustro-Hungary in the wake ofWorld War I, and more especially in connection with thePolish-Bolshevik War that followed.
The City ofExeter, inDevon, England, has used the motto since at least 1660, when it appears in a manuscript of the local chronicler,Richard Izacke. Izacke claimed that themotto was adopted in 1588 to signify the city's loyalty to the EnglishCrown. According to Izacke, it wasQueen Elizabeth I who suggested that the city adopt this motto (perhaps in imitation of her own motto,Semper eadem, "Ever the same"); her suggestion is said to have come in a letter to "the Citizens of Exeter," in recognition of their gift of money toward the fleet that had defeated theSpanish Armada.John Hooker's map of Exeter of around 1586 shows the city's coat of arms without the motto, suggesting that the city's use of the motto is no older than this. However the city archives do not hold any letter relating to the motto, and Grey (2005) argues that the Elizabethan origin of the motto may be no more than a local myth, since it is not recorded in contemporary chronicles, and that it may have been adopted at the Restoration of the Stuart monarchy to compensate for the city's less than total loyalty to the crown during theEnglish Civil War.
Various bodies associated with the city of Exeter also use the motto:

"Semper fidelis" is the motto of the town ofSt. Malo, inBrittany, France. The date of its adoption is not known, but it appears to have been in use in the 17th century,[15] replacing an earlier motto, "Cave canem".
"Civitas Calvi Semper Fidelis" may have been the motto of the city ofCalvi, Balagna area inCorsica for 500 years.[citation needed]
"Semper Fidelis" is the motto of the city ofWhite Plains, inNew York, United States.

The south-western English city of Exeter has used the mottosemper fidelis since no later than 1660, inspiring its use by several south-western English military units.
In 1685 the motto was used by Duke of Beaufort when The Duke of Beaufort's Regiment of Foot, or Beaufort Musketeers, were raised to defend Bristol against theDuke of Monmouth's rebellion. It was numbered as the 11th Regiment of Foot when the numerical system of regimental designation was adopted in 1751 and was designated the regiment for North Devonshire (later theDevonshire Regiment).
The 1st (Exeter and South Devon) Rifle Volunteer Corps, raised in Exeter in 1852, was using the motto on its cap badge by 1860 at the latest; theIllustrated London News reported its use in its 7 January 1860 issue.[16] The motto was continued byThe Devonshire Regiment of theBritish Army.
The motto was further continued on the badges of theDevonshire and Dorset Regiment when the Devonshires were amalgamated into them in 1958. This use of the motto evidently derives from these regiments' close connection with the city of Exeter, where they had a base from their foundation (see the Illustrated London News article referenced above) until their disappearance by amalgamation intothe Rifles in 2007.
The Irish units in France used a similar motto, "Semper et ubique Fidelis", meaning "Always and Everywhere Faithful". These units, forming theIrish Brigade, were raised in 1690-1 under the terms of the Treaty of Limerick, which ended the war betweenKing James II andKing William III in Ireland and Britain. As the native Irish army in exile, "Semper et ubique Fidelis" was a reference to their fidelity to the Catholic faith, King James II, and to the king of France. For decades the Irish Brigade served as an independent army within the French army, remaining "Always and Everywhere Faithful" to their native Gaelic Irish traditions (such as having the men elect their own officers, unheard of in France and England).[17]
Antoine Walsh's regiment of the Irish Brigade is noted for aiding the American cause in the American Revolution, when they were assigned asmarines to John Paul Jones's ship, theBonhomme Richard.[18]
The involvement of Irish Brigade soldiers serving as marines in theAmerican War of Independence may have inspired the eventual adoption of the motto "Semper Fidelis" by the US Marines.
The phrase "Semper Fidelis" was made the official motto of the Marine Corps byCharles Grymes McCawley, the eighth Commandant of the Marine Corps, who was born and raised in Philadelphia, Pennsylvania which had a large Irish Catholic population. McCawley owed his commission to SenatorPierre Soulé of Louisiana, a Catholic born and raised in France, who would have been well aware of the Irish Brigade's service as Marines during the American Revolution.[19]
The French 47th Infantry Regiment used "Semper fidelis" as its motto.
"Semper fidelis" is the motto of the cadets corps of the Dutch Royal Military Academy.[20] The corps was founded on 24 November 1828.

"Semper fidelis" is also the motto of the11th Infantry Regiment, which was founded in May 1861 by PresidentAbraham Lincoln. It served as part of the Army of Ohio and later in the Indian wars, Spanish–American War, 1916 Mexican Border war,World War I,World War II, and theVietnam War. Today the regiment trains young Army officers atFort Moore, Georgia.

"Semper fidelis" is the motto ofThe West Nova Scotia Regiment (of theCanadian Armed Forces), formed in 1936. It inherited the motto fromThe Lunenburg Regiment, formed in 1870.

TheUnited States Marine Corps adopted the motto "Semper Fidelis" in 1883, on the initiative of ColonelCharles McCawley (29 January 1827 – 13 October 1891), the 8thCommandant of the Marine Corps.[21]
There were three mottos prior to Semper Fidelis includingFortitudine (meaning "with courage") antedating the War of 1812,Per Mare, Per Terram ("by sea, by land"; presumably inherited from the BritishRoyal Marines, who have that as a motto), and, up until 1843, there was also the Marines' Hymn motto "To the Shores of Tripoli". "Semper fidelis" signifies the dedication and loyalty that individual Marines have for 'Corps and Country', even after leaving service. Marines frequently shorten the motto to "Semper Fi"/ˌsɛmpərˈfaɪ/.

"Semper Fidelis" serves as the motto of a number of schools around the world:
B. Burke (1884) and Chassant & Tausin (1878), and other sources, list a number of similar mottos that appeared in family or city coats of arms in Great Britain, Ireland and France, though none was ever as popular as "Semper fidelis". They include:
