The Kingdom of Dyfed (Welsh pronunciation: ['dəvɛd]), one of several Welsh petty kingdoms that emerged in 5th-century sub-Roman Britain in southwest Wales, was based on the former territory of the Demetae (modern Welsh Dyfed). The medieval Irish narrative The Expulsion of the Déisi attributes the kingdom's founding to Eochaid, son of Artchorp, who was forced across the Irish sea in the 5th century; his descendants founded the line of the kings of Dyfed down to "Tualodor mac Rígin" (Tudor map Regin).[2] The Normans invaded Wales (1067 to 1100), and by 1138 incorporated Dyfed into a new shire called Pembrokeshire after the Norman castle built in the Cantref of Penfro and under the rule of the Marcher Earl of Pembroke.
