In medieval times, Durham was a major centre of both political and ecclesiastical power, mainly due to its strategic
importance near the border with Scotland. The Prince Bishops[?] had in their Palitinate[?] the power over life and death, coined their own money and maintained their own armies. Every Bishop of Durham from 1071 to 1836 was a Prince Bishop except the first Norman-appointed bishop Walcher, who was an Earl-Bishop.
