Peter's Pence was originally an annual tribute of one penny from each householder owning a land of a certain value to the Pope and had been collected in England since the reign of King Alfred. In the twelfth century it was fixed at an annual sum of £200 for the whole realm. It was not the largest payment to Rome but it is argued by Stanford Lehmberg that it was deliberately mentioned in the Act because it was theoretically paid by laymen and thus might have seemed more intolerable than payments affecting clerics only.
