戈弗雷·德·圣 - 奥马尔是法兰德斯骑士和圣殿骑士团的创始人之一。
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.
