Godfrey de Saint-Omer was a Flemish knight and one of the founders of the publicly known Templar Order.
In the early 12th century, Bernard de Clairvaux sent Saint-Omer and eight other trusted Templars, including future Grand Master Hugues de Payens, to the Holy Land to find Solomon's Temple. Around 1119, King Baldwin II of Jerusalem gave them Al-Aqsa Mosque as their headquarters, believing that the Templars worked to protect Christian pilgrims. Al-Aqsa Mosque was later named Solomon's Temple.
After nine years of traveling, Saint-Omer and his fellow Templars returned to France, where Bernard and Payens wrote the Latin Rule, which outlined the rules of the Order. The Templar Order was recognized at the Council of Troyes in 1129.
