In 1487, by the Statute of Harlech, the three principalities of Gwynedd, Powys and Morgannwg were brought back to political life. The case for Gwynedd and Powys were clear. The King needed a strong base to provide financial security for the crown. To that end, historic Gwynedd was the obvious choice. Powys, being the ancestral principality of the Glyndwr family was brought back and entrusted to the kings son, Prince Maredudd. Morgannwg was not the obvious third principality. Dehubarth had an older, more respected claim, and again, the King had an ancestral link to that House. However, the most successful invasions of Wales had all followed the same route. That route being through South Wales. A strong lord would not only aid the king in providing strong control over the entire kingdom, but would also act as an initial bulwark should the English invade. The only question remaining to Owain was, to which family should the honour of Morgannwg be bestowed.
The House of BrenIn the end, Owain opted for the Lords of Senghenydd. The family had long held the lands north of Caerphilly and Lord Iolo Bren (1380-1443) had fought alongside Owain Glyndwr in the First War of Independence. The House of Bren descended from Meurig Senghenydd who held land in the north of the area. Meurig was one of the last truly independent Morgannwg lords, with his son Ifor Bach continuing this independent line. Iolo Brens Great-Grandfather, Llywelyn Bren (1267-1318) was the last of the Southern Lords to mount a serious challenge to the English (during the reign of Edward II). It was this streak of independence along with the actions of Iolo during the First War of Independence which secured from the king the Grant of Honour which raised the family to the Principality of Morgannwg.
The last Lord of Senghenydd (Gwillym Bren 1443-84) was an ambitious man. The chance to empower his family within the newly independent Wales was one he took with both hands. Gwillym himself married Angharad Mortimer, daughter of Edmund Mortimer (brother in law to Owain Glyndwr). His children would therefore be descended from kings of England and the House of Mathrafal. Gwillym himself was descended from the House of Aberffraw via his mother (Lady Angharad ferch Gruffud Fychan). She was a descendent of one of Dafydd III of Wales' illegitimate sons (Dafydd Goch). From earlier generations Gwillym was also descended from William the Conqueror and Hywel Dda. With such a wide cast of Royal ancestors, Gwillym lobbied hard for the honour of raising his family to the Princedom of Morgannwg.

The Royal Seat - Senghenydd PalaceThe Princes of Morgannwg came originally from the Lords of Senghenydd, who had their seat of power near to the English town of Caerphilly. From the time of Iolo Bren, Lord of Senghenydd, the family resided in what became known as Senghenydd House, built on the outskirts of Caerphilly. During the reign of Dafydd the First of Morgannwg work began on modernising the house in the German style. By the end of his daughters reign (Heledd in 1582) the house was now referred to as Senghenydd Palace.
This would be the home of the Princes until the time of Cystennin II of Morgannwg (Prince between 1673-1733) who began the work to again modernise the Palace. This work was interupted by the English Occupation during which time the Palace was used as the residence of the Anglo-Scots Army Commander. Following the rise of the House of Morgannwg as Welsh king and the Welsh Restoration, the Palace briefly re-emerged as the home of the Welsh Court. This ended with the move of the Royal Court to the Fortress & Palace of Caerphilly which remained the home of the Welsh Royal Family until the move to Cwm Hydref. The Palace of Senghenydd was retained as the Summer Palace of the Welsh kings during this period.During the 20th Century the Palace was neglected until the outbreak of the Great War in 1939. The German Army took over the use of the Palace in 1937 using it as their headquarters in Wales. With the German expulsion and the placing of Iago under house arrest in Castell Coch, Field Marshall Thomas took over the Palace as his official residence. In 1942, with the separation of the Crown from the Principality of Morgannwg, Thomas signed the Palace over to the Edling, Owain, to be the seat of the Princes of Morgannwg separate to the Crown. This role has continued with the heir to the Welsh Throne now being Prince of Glamorgan in his or her own right owning the use of the Palace as their official residence.
Today the Palace is open to the public during the summer and acts as the official residence for the Office of Prince of Morgannwg for Prince Owain II of Morgannwg.
