TheLordship of Glamorgan was one of the most powerful and wealthy of theWelsh Marcher Lordships. The seat wasCardiff Castle. It was established by the conquest ofGlamorgan from its native Welsh ruler, by theAnglo-Norman noblemanRobert FitzHamon,feudal baron of Gloucester, and his legendary followers theTwelve Knights of Glamorgan. The Anglo-Norman Lord of Glamorgan, like all Marcher lords, ruled his lands directly by his own law: thus he could, amongst other things, declare war, raise taxes, establish courts and markets and build castles as he wished, without reference to theEnglish Crown. These privileges were only lost under theLaws in Wales Acts 1535–1542. Though possessing many castles, the main seat of the Lordship wasCardiff Castle.
