The Twelve Knights of Glamorgan were a "legendary" group of mercenaries who followed Robert Fitzhamon (d.1107), the Norman conqueror of Glamorgan. Although Fitzhamon was an actual historical figure, 16th-century historians, in particular Sir Edward Stradling, built upon the legend of a group of knights who ruled over the county in his stead. The fact that many of the knights existed during the period gave the legend credence.
