Wales was originally a number of small kingdoms with their own laws and practices. Hywel brought most of the kingdoms under one rule. For the sake of convenience and fairness, he created a set of laws that would apply to all the territories over which he had influence. Or did he?
Known in Welsh as Cyfraith Hywel, the Laws of Hywel (the earliest copies we have are Latin versions from the early 13th century) have a prologue that explains how Hywel called on priests and lawyers to meet in Dyfed and create a common set of laws. This anecdote might not be true: since we have no earlier Welsh versions, there is a theory that the story of the gathering of lawyers and priests was created specifically to counter the objections of the then-current Archbishop of Canterbury, John Peckham. Peckham, acting on behalf of King Edward I, was very critical of the Welsh, their ruler Llywelyn ap Gruffudd, and the bishop of St. David's in Wales. The gathering of priests might have been a story concocted to suggested that Wales' legal system had Christian influence at the foundation.
Whatever the origin of these laws, cultural memory attributes them to Hywel. One of the features that stands out is recognition of the rights of women. A small sample from a 1915 English translation:
Chap. i. The laws of the women.
1. The first of them is: if a woman be given in marriage, she is to abide by her agweddi (marriage portion) unto the end of the seventh year; and if there be three nights wanting of the seventh current year, and they separate, let them share into two portions everything belonging to them.
54. If a man willeth to separate from his wife, and after he shall have separated, willet another wife; the first, that has been divorced, is free: for no man is to have two wives.
55. Every woman is to go the way she willeth, freely, for she is not to be revenant; and nothing is due from her, except her amobyr (marriage fee), and only one amobyr; for a woman owes no ebedi (a relief payable to the superior lord), only her amobyr; therefore, as a man is to pay only one ebediw, in like manner, a woman is to pay only one amobyr; for there is no ebediw from her, only her amobyr.

Hywel died in 950, but the Law lived on...until 1284 and the Statute of Rhuddlan, that is, which was established by Edward I of England. To do that, however, Edward would have to conquer Wales, but that's a story we'll start tomorrow.
