Concordat of London, 1107
The Concordat of London (1107) suggested a compromise that was taken up in the Concordat of Worms. In England, as in Germany, a distinction was being made in the king's chancery between the secular and ecclesiastical powers of the prelates. Employing the distinction, Henry gave up his right to invest his bishops and abbots and reserved the custom of requiring them to come and do homage for the "temporalities" (the landed properties tied to the episcopate), directly from his hand, after the bishop had sworn homage and feudal vassalage in the ceremony called commendatio, the commendation ceremony, like any secular vassal. The system of vassalage was not divided among great local lords in England as it was in France, for by right of the Conquest the king was in control.
