Robert of Courson (Robertus de Corcun, ca. 1160/70–1218) was an English-born theologian who studied under Peter the Chanter at the University of Paris, where he later became a master of theology. His Summa (c. 1208–1214) is a massive compendium of moral theology treating simony, usury, oaths, vows, and ecclesiastical discipline, drawing on canon law, Scripture, and the Parisian schools. Appointed cardinal legate by Pope Innocent III in 1212, he conducted sweeping reform councils across France and played a formative role in preparing the Fourth Lateran Council (1215). He died at the Crusaders' camp at Damietta in 1218.
