Outside influences: Rome, Christianity, and the ecclesiastical system.
Two powerful influences had evidently already partially arrested the tribal system in Wales, and turned it as it were against its natural bent into fixed and hardened grooves, before it assumed the shape in which it appears in the Welsh laws. These two powerful influences were (1) Roman rule and (2) Christianity. Their first action was to some extent exercised singly and apart, though concurrently in point of time. But their separate influences were afterwards surpassed and consolidated by the remarkable combination of them both which was presented in the ecclesiastical system.
The influences of Christianity, and of the later ecclesiastical system, were powerfully exerted in Ireland also; but the Irish tribal system differed from the Welsh in its never having passed directly under Roman imperial rule.
The Brehon laws of Ireland perhaps owe their form and origin to the necessity of moulding the old traditional customs to the new Christian standard of the ecclesiastics, under whose eye the codification was made. So, also, the Welsh laws of Howell the Good, and the Saxon laws of Ine and his successors, all reflect and bear witness to this influence, and had been no doubt moulded by it into softer forms than had once prevailed. At least the harshest thorns which grew, we may guess, even rankly upon the tribal system, must, we may be sure, have been already removed before our first view of it. [p233]
In fact, nearly all the early codes, whether those of Ireland, Wales, or England, or those of German tribes on the Continent, bear marks of a Christian influence, either directly impressed upon them by ecclesiastical authorship and authority, or indirectly through contact with the Roman law, which itself in the later edicts contained in the Codes of Theodosius and Justinian had undergone evident modification in a Christian sense.
So far as the Welsh tribal system is concerned, it is quite clear that whatever had been the influence upon it of direct Roman imperial rule and early Christianity, it submitted to a second and fresh influence in the tenth century.
This appears when we consider the avowed motives and object of Howell the Good in making his code. Its preface recites that he 'found the Cymry perverting the laws and customs, and therefore summoned from every cymwd of his kingdom six men practised in authority and jurisprudence; and also the archbishop, bishops, abbots, and priors, imploring grace and discernment for the king to amend the laws and customs of Cymru.' It goes on to say that, 'by the advice of these wise men, the king retained some of the old laws, others he amended, others he abolished entirely, establishing new laws in their place;' special pains being taken to guard against doing anything 'in opposition to the law of the Church or the law of the Emperor.' [304]
Finally, it is stated in the same preface that Howell the Good went to Rome to confirm his laws by papal [p234] authority, A.D. 914, and died A.D. 940. It may be added that the reference to the 'law of the Emperor' was no fiction, for 'Blegewryd, Archdeacon of Llandav, was the clerk, and he was a doctor in the law of the Emperor and in the law of the Church.'
The tribal division among male heirs survives these influences.
In connexion with this ecclesiastical influence there is a curious exception which proves the rule, in the refusal of Howell the Good to give up the tribal rule of equal division among sons, which lay at the root of the tribal system, and to introduce in its place the law of primogeniture.
