Glamorgan has supported the English Crown for a long time (read something once about a "Glamorgan kiss" an act of betrayal to the Welsh in favour of the English by a Glamorgan noble?)
Quote:
"Glamorgan, now falling under the protection of the crown, was also involved in the conflicts of the crown. With the start of the First English Civil War, there was little support from the Welsh for the Parliamentarians.[53] Glamorgan sent troops to join Charles I at the Battle of Edgehill, and their Member of Parliament Sir Edward Stradling was captured in the conflict.[54] In the Second English Civil War, the war came to Glamorgan at the Battle of St Fagans (1648), where the New Model Army overcame a larger Royalist to prevent a siege of Cardiff."
(The New Model Army wasn't the group!)
