“Wales is, as everyone knows, pre-eminently the land of castles. Through those districts with which we are specially concerned, castles great and small, or the ruins or traces of castles, meet us at every step. The churches, mostly small and plain, might themselves, with their fortified towers, almost count as castles. The towns, almost all of English foundation, were mostly small; they were military colonies rather than seats of commerce. As Wales had no immemorial cities like Exeter and Lincoln, so she had no towns which sprung up into greatness in later times, like Bristol, Norwich, and Coventry. Every memorial of former days which we see in the British land reminds us of how long warfare remained the daily business alike of the men in that land and of the strangers who had made their way into it at the sword’s point.”
Through the reigns of the Plantagenet kings the oppression and cruelties to which the Welsh were subjected drove them repeatedly to reprisals. At times they were successful.
During the commotions caused by the misrule of King John and the incapacity of Henry III. the Welsh took occasion to stretch their limbs and recover some of the lands that had been wrested from them, and to throw down the castles that were an incubus upon them.
There were three Welsh kingdoms, or principalities. Gwynedd, roughly conterminous with the counties of Anglesey, Carnarvon, Merioneth, and parts of Denbigh and Flint. Powys, sadly shrunken, still comprised Montgomeryshire and Radnor and a portion of Denbigh. The third principality, Deheubarth or Dynevor, composed of Pembrokeshire, Cardiganshire, Carmarthenshire, and Glamorgan. Brecknock was claimed as part of it, but was an enclave in which the Normans had firmly established themselves. Monmouthshire also belonged to Deheubarth.
The king of Gwynedd claimed supremacy as head over the rest, and although this was allowed as a theory, if practically asserted it always met with armed resistance. But this was not all that went to weaken the Welsh opposition. Each prince who left sons carved up his principality into portions for each, and as the brothers were mutually jealous and desirous of acquiring each other’s land, this led to incessant strife and intrigue with the enemy in the heart of each of the three principalities. A great opportunity had offered. Rhodri the Great had united all Wales in his own hands, as mentioned already. But the union lasted only for his life; all flew apart once more at his death in 877, and that just at the moment when unity was of paramount importance.
Llewelyn ab Iorwerth, surnamed “the Great,” was king of Gwynedd at the beginning of the thirteenth century, and he had sufficient wit to see that the only salvation for Wales was to be found in its reunion, and he attempted to achieve this. As Powys was obstructive, he had to fight Gwenwynwyn its king, then to subject Lleyn and Merioneth.
In 1202 Llewelyn was firmly established in Gwynedd, and he married Joan, the daughter of King John, who proceeded to reinstate Gwenwynwyn in Powys. In 1211 this prince sided with Llewelyn against John, who, furious at this act of ingratitude, hanged twenty-eight Welsh hostages at Nottingham.
Llewelyn now turned his attention to the conquest of South Wales. He stormed one castle after another, and obtained recognition as prince of Dynevor. But in 1216 the false and fickle Gwenwynwyn abandoned the Welsh side and went over to that of the English. After some fighting Llewelyn submitted to Henry III. at Worcester in 1218.
His grandson, another Llewelyn, was also an able man, but he lacked just that essential faculty of being able to detect the changes of the sky and the signs of the times, and that ruined him.
In 1256 Llewelyn was engaged in war against the English. He had done homage to Henry III. in 1247, but the unrest in England caused by the feeble rule and favouritism of Henry had resulted in the revolt of the barons. Llewelyn took advantage of this condition of affairs to recover Deganwy Castle and to subdue Ceredigion. Then he drove the unpatriotic son of Gwenwynwyn out of Powys. The same year he entered South Wales, and was everywhere victorious. Brecon was brought under his rule, and the castles held by the English were taken and burned. But Llewelyn’s great difficulty lay with his own people, though his power was used for the recovery of Wales from English domination.
