Latin patriarch of Jerusalem (1128-1130) who strengthened the Latin Church in Outremer but quarreled with his kinsman King Baldwin II of Jerusalem.
Stephen had been a knight and viscount in Chartres, but later he entered the church and became abbot of St. John in Chartres. He was elected patriarch while visiting the Holy Land in 1128.
Stephen created a new Latin diocese at Sebastea and organized the fledgling Knights Templar. He also tried to reassert Daibert of Pisa’s demands concerning the patriarchate’s possessions in Jerusalem and also claimed the city of Jaffa (mod. Tel Aviv-Yafo, Israel), thereby causing a breach with the king that lasted until Stephen’s death.
