The Holy Land is the terrain that gives the Knights of the Temple their founding purpose and, when it is lost, turns that purpose into memory and legend. In Casaubon’s account, it is at once a Christian kingdom won by crusade, a contested landscape where the Templars serve and fight, and a vanished homeland whose loss leaves the order without the war for which it was created.

A kingdom won, an order founded

The narrative begins its account of the Templars with the First Crusade: Godefroy worships at the Holy Sepulcher and fulfills his vow, and Baudouin becomes the first king of Jerusalem. Establishing a Christian kingdom in the Holy Land, however, does not mean conquering or holding all of Palestine. The new occupiers face continued danger, and pilgrims travel through a region where Christian rule remains insecure.

In 1118, during the reign of Baudouin II, Hugues de Payns and eight companions arrive and establish the nucleus of a religious order with a military charge. Its members take the vows of poverty, chastity, and obedience, as well as a fourth vow to defend pilgrims. The king, the bishop, and others in Jerusalem support them with money and lodging; they are eventually settled in the cloister of the old Temple of Solomon. Their location and name bind the order to the sacred geography of Jerusalem, while their vow makes the protection of travelers in the Holy Land its practical reason for being.

Casaubon distinguishes the first companions from later recruits. He imagines Hugues and his original companions as idealists caught up in crusading fervor, but later members as younger sons seeking adventure or a new life. For those with limited prospects at home, the kingdom could seem like a place to make a fortune: joining the Templars offered food, clothing, travel, fighting, and the promise of spiritual reward. Yet the reality was punishing. A knight might spend days in the desert, isolated except for fellow Templars and the occasional enemy, riding under the sun and facing thirst and combat. The attraction of the Holy Land thus rests beside the bodily hardship of occupying it.

Contact across religious lines

The account resists reducing the Templars to a single image. They are soldiers in a religious war, but Casaubon also recalls a story of their conduct toward a Muslim visitor in Jerusalem. When the ambassador of the emir of Damascus comes to pray in a small mosque converted into a Christian church, a Frank objects and begins to rough him up. The Templars instead eject the intolerant Frank and apologize to the Muslim. Their actions suggest a chivalric respect that coexists with the order’s military opposition to Muslim forces.

That contact also becomes a source of suspicion. Casaubon notes that dealings with esoteric Muslim groups were later included among the accusations made against the Templars at their trial; such dealings may, he allows, have occurred. In his interpretation, the knights’ long residence in the region exposed them to a culture they could not simply treat as an enemy. He pictures them as rough soldiers who might adopt the customs of those around them, while cautioning that Christian chroniclers such as William of Tyre were not objective witnesses and took opportunities to vilify the order. The Holy Land is therefore not only a battlefield in this account: it is also a place of prolonged cultural and religious encounter, and a setting in which fraternization could later be recast as evidence against the Templars.

Defeat and the loss of purpose

The later history of the crusades strips away the Templars’ heroic image without erasing their commitment to their vocation. More than a century after the order’s foundation, the earlier figures of Jerusalem’s Christian kingdom have faded, and the crusading enterprise has suffered repeated defeats. In 1244 Jerusalem falls definitively to the opposing forces. Casaubon describes the war, begun generations earlier, as lost; the Christians lay down their arms in a land now associated with peace and the cedars of Lebanon. The loss becomes both a military ending and an elegy for the Templars’ unrealized epic.

Even after two centuries of failure, Louis IX continues to believe in a crusade, and the Templars follow him because fighting for the cause is their assigned purpose. At Damietta, Louis chooses to land despite the enemy’s defenses, urging his followers to remain united whether they are defeated as martyrs or victorious for the greater glory of God. The Templars do not share his confidence, but they have been trained to embody the ideal and follow him into the campaign. The initial landing succeeds, and the Saracens abandon Damietta; Louis then hesitates to enter the city, fearing treachery where there is none. His later choice to march toward Cairo, encouraged by Robert d’Artois, leads into disaster. The account connects the Templars’ loyalty to a recurring danger: an ideal of holy warfare persists even when military judgment and circumstances turn against it.

The defeat brings material suffering and political humiliation. Grand Master Guillaume de Sonnac dies in Greek fire, disease and shortages afflict the Christian army, and the force is routed. Louis is gravely ill with dysentery; Damietta is lost, and the queen must negotiate a ransom of five hundred thousand livres tournois. After the king returns to Saint-Jean-d’Acre, the Templars try to negotiate with Damascus. Louis, angered that they acted without him, forces the new grand master to retract his promises, kneel, and ask forgiveness before Muslim ambassadors. Their service has not prevented the king from humiliating them to reassert his authority. Casaubon links that episode to the later suppression of the order: rulers can use the Templars’ strength when it serves them, then turn against them when their power becomes inconvenient.

A vanished homeland, a lasting legend

In 1291, Saint-Jean-d’Acre is conquered and its inhabitants are put to the sword. With its fall, the Christian kingdom of Jerusalem is gone for good. The Templars remain richer, more numerous, and more powerful than before, but the Holy Land that gave their military vocation its purpose no longer has a Christian kingdom for them to defend. The contrast is stark: institutional power survives the cause that once made it intelligible.

Casaubon renders the Templars’ later European life as an existence in splendor and isolation. They occupy commanderies across Europe and the Temple in Paris, yet continue to dream of Jerusalem: its plateau, the church of Saint Mary Lateran, its votive chapels, workshops, granaries, stables, horses, soldiers, red-crossed white cloaks, and arriving pilgrims and envoys. The remembered Holy Land is not an abstract symbol alone; it is a crowded working world of religious buildings, military infrastructure, trade, and movement. Its sensory and material detail makes the loss feel like the disappearance of an entire social order.

From that loss, Casaubon suggests, the Templars’ legend could grow. In the melancholy of a diminished and aging glory, the knights might lend an ear to the hidden doctrines of Muslim mystics; later readers could imagine their unused power as boundless. The Holy Land thus remains active in the novel after it has ceased to be a Templar possession. Its defeat leaves behind a gap between the order’s surviving wealth and its lost mission, and the legend of secret knowledge and unconstrained power fills that gap. The place is at once historical ground, the measure of the Templars’ failure, and the absent center around which their enduring myth gathers.
