The Order of the Poor Knights of Christ of the Temple of Solomon, also called the Order of the Temple, whose members are known as knights templar, was one of the most powerful military orders christian of the Middle Ages. Remained active for a little less than two centuries. It was founded in 1118 or 1119 by nine French knights, led by Hugo de Payns after the first crusade. Its original purpose was to protect the lives of the christians who made the pilgrimage to Jerusalem after its conquest. The order was recognized by the Latin patriarch of Jerusalem, Garmond of Picquigny, which was imposed as a rule of the augustinian canons of the Holy Sepulchre. This rule, within the context of the knights templar, is known as a Rule of Latin.
