Owain Glyndŵr captures Aberystwyth in 1404 during an uprising against English rule. By then, long intermarriage among Anglo-Saxon, Norman and Welsh families made ancestry difficult to distinguish. Even surnames could give an uncertain guide to those identities. Glyndŵr signs a mutual-security treaty with the king of France at the castle, intensifying English hostility. English forces retake Aberystwyth in 1408 and rebuild and reinforce it as a seat of government.
