Deheubarth (the Lord Rhys)

The realm of south-west Wales of the House of Dinefwr, formed when Hywel Dda united Dyfed and Seisyllwg c. 920 (historians note that Deheubarth was a regional name rather than a kingdom of fixed form).

Overrun by the Normans after Rhys ap Tewdwr was killed in 1093; rebuilt from 1155 by the Lord Rhys, without Norman south Pembrokeshire and Gower, and divided among his sons after his death in 1197.
