The Welsh had never been city builders or dwellers in cities. They had suffered the old Roman towns to fall into decay, the walls to crumble into shapeless heaps of ruins. They lived in scattered farms, and every farmer had his _hafod_, or summer residence, as well as his _hendre_, or winter and principal home. Only the retainers of a prince dwelt about him in his palace, or _caer_. And now they saw strongly walled and fortified towns starting up at commanding points on the roads and beside all harbours. The arteries of traffic, the very pores of the land, were occupied by foreigners. As Freeman further observes:-- “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.
