In the early middle ages Wales was divided in several kingdoms, each with its own laws. Hywel ap Caell, usually known as 'Hywel Dda' or Hywel the Good, who became king over nearly all of Wales in 942, is credited with having brought these different systems into a single body of law, although three different versions exist: for Venedotia (north Wales), Dimetia (south Wales), and Gwent (south-east). The Law continued in use in Wales until the union with England in 1536. This page contains the preamble ('Hywel da ? '), and in the lower margin is the ink stamp of Richard Morris, who, with his brothers William and Lewis, were responsible for the preservation of large numbers of medieval Welsh texts: from about 1725 they spent about 40 years collecting Welsh manuscripts, and making transcripts of those they could not acquire.
