In 1119, a French knight named Hugues de Payens approached King Baldwin II of Jerusalem with a proposal: he and eight companions would form a monastic order dedicated to protecting Christian pilgrims travelling the dangerous roads between the port of Jaffa and the holy city of Jerusalem. Baldwin granted them quarters in the royal palace — built on the site of Solomon's Temple. The order took its name from this location: the Poor Fellow-Soldiers of Christ and of the Temple of Solomon. The Knights Templar.
Their early years were genuinely modest — nine knights, living in poverty, performing escort duty. But at the Council of Troyes in 1129, the Templar rule was formally approved by the Church, and Bernard of Clairvaux — the most influential churchman of the age — wrote a celebrated treatise in their praise, De Laude Novae Militiae (In Praise of the New Knighthood). Bernard's endorsement transformed the Templars overnight. Donations of land, money and personnel flooded in from across Europe. Within a generation, they were one of the wealthiest and most powerful organisations in the Western world.
The Templars operated on three levels simultaneously: as a military force in the Holy Land (elite shock troops, the first to charge and last to retreat in battle — they were forbidden to surrender unless the odds were more than three to one); as a diplomatic entity (negotiating directly with Muslim rulers, maintaining relationships across religious lines); and as a financial institution (managing the flow of money, men and supplies between Europe and the Crusader states). This third role — banking — would prove their most consequential and most dangerous innovation.
