Deheubarth
Deheubarth was a south-western kingdom or
principality of medieval
Wales. It was created in about
950 by
Howell the Good ("Hywel Dda") out of the territories of Seisyllwg and
Dyfed, both of which had come into his possession. Deheubarth, like several other Welsh kingdoms, continued to exist until the
Norman Conquest of Wales, but constant power struggles meant that only for part of the time was it a separate entity with an independent ruler.
