Glamorgan

Glamorgan was a wealthy Welsh marcher lordship centred on Cardiff Castle. Its lordship came to Hugh Despenser the Younger through his wife Eleanor, but he was executed in 1326; their son Hugh was the Despenser claimant in 1337.

The Despensers recovered Glamorgan in 1338. It later passed through the Beauchamp and Neville families to Richard III, before merging with the crown under Henry VII in 1495. The Laws in Wales Acts of 1535–1542 ended the marcher privileges that had allowed lords to wage war and build castles without royal permission.
