The “Larmenius Charter” (or “Carta Transmissionis”) is a manuscript allegedly written by Johannes Marcus Larmenius in February 1324. Written in Latin, it lists 22 successive Grand Masters of the Knights Templar after Jacques de Molay, concluding with Bernard-Raymond Fabré-Palaprat, who revealed the Charter in 1804. Styled as an ancient Templar Codex and housed at Mark Masons’ Hall in London, its authenticity is disputed based on code analysis and discovery circumstances but never definitively disproven. According to the Charter, Larmenius—then in his seventies—rstates that the Grand Mastership of the Knights Templar Order was verbally transmitted to him ten years earlier (March, 1314) by the imprisoned Jacques de Molay, the last Grand Master of the Knights Templar. Larmenius was a Palestinian-born Christian who joined during the Order’s final Crusader years and later served as Seneschal after relocating to Cyprus post-1295. Due to age, Larmenius transferred leadership to Franciscus Theobaldus, Prior of Alexandria. The Charter aimed to ensure an unbroken line of Grand Masters and initiated the Order’s “Second Phase” during its “Dark Period,” leading to partial revival at the 1705 Convent General in Versailles where Philippe, Duke of Orléans became Grand Master. The Order dissolved during the French Revolution when Grand Master Duke Timoléon de Cossé Brissac was killed; his furniture was bought by Brother Ledru (the physician’s son), who found the Charter hidden inside and gave it to Fabré-Palaprat in 1804. Oral transmission of leadership was likely necessary due to persecution; such oral successions were probably later documented for accuracy. The document's credibility hinges less on age than on whether this succession method existed under Jacques de Molay. Given their intelligence networks and preparedness for hostility, such contingency plans are plausible—particularly considering Father Larmenius’s role at that time. Many records were destroyed by church authorities; those preserved entailed significant risk. In this context, oral transmission after 1314 was likely the safest approach. Critics argue that parts of the charter use modernised Latin forms unusual for its claimed origin, but this offers little evidence against its authenticity. Language evolves, and each transcription may reflect contemporary usage. The code likely aimed to hide meaning from outsiders, not serve as an official record. These points do not undermine the theory of oral transmission or the legitimacy of what is now called the Larmenius Charter; rather, they suggest it could be a later copy documenting actual leadership succession after 1314. Fabré-Palaprat, linked with the modern Order of the Temple during the Enlightenment and influenced by its ideals, viewed “Templar” and “Templarity” as embodying assistance, protection, decency, dedication and chivalry—the founding principles of his new Order. In the 19th century Romantic era, these values attracted prominent supporters. Templar legends—lost treasures, Ark of the Covenant, Holy Shroud, Holy Grail and Rosslyn Chapel—became woven into mystical narratives. In Napoleonic France—when Napoleon replaced monarchy with his own order—recognising Fabré-Palaprat’s revived Order further established royal authority; Napoleon’s official recognition in 1804 added credibility. The Order resurged when Napoleon’s inner circle revitalised it; Napoleon III later raised its profile further. After his death it lost its main patron; subsequent wars fragmented unity within the International Order of the Temple. Today many groups worldwide use variations of the Templar name. The direct successors to Fabré-Palaprat’s Templars are those using Ordo Supremus Militaris Templi Hierosolymitani (OSMTH), headquartered in Paris. This group remained loyal to Fernando de Sousa Fontes as Grand Master despite his appointment by his father without election. The Order’s motto comes from Psalm 115:1: “Non nobis Domine non nobis sed Nomini Tuo da gloriam”—“Not for us Lord not for us but to Thy name give glory.” Today, the Order is a secular-military order of chivalry open to accomplished Christian men and women—Knights and Dames—who uphold high ethical standards and wish to continue Templar traditions. The mission of the modern Order is to prove that spiritual idealism remains relevant today, blending tradition with patriotism and civic duty. Modern Templars use words instead of swords, focusing on peace, humanitarian aid, mutual support, education, and upholding Christian ethical values. Action must accompany these ideals; each Knight should begin fostering chivalry within their family before extending it to wider society.
