Gruffydd II ap Madog, Lord of Dinas Bran

Gruffydd Maelor (died 1269) was a Prince of Powys Fadog. He reigned for 33 years and married into the House of Stanley. Following the Anglo-Welsh Treaty of Montgomery, he submitted to Llywelyn ap Gruffudd, Prince of Wales.

Lineage

He was the eldest son of Prince Madog ap Gruffydd Maelor and inherited his father's lands and title in partible succession along with his four brothers Gruffudd Iâl, Maredudd, Hywel and Madog Fychan.

His father's policy of alliance with the large and powerful Gwynedd changed over his 33-year reign (1236-1269); pressure from Gwynedd, and Gruffydd's marriage to the daughter of an English landowner, caused him to seek support from the English king.

However, support from England failed to arrive and in 1258 he was forced to submit to Llywelyn ap Gruffudd.

Around 1260, Gruffydd started the construction of Castell Dinas Brân in the Dee Valley. Afterwards, Llywelyn was recognised as Prince of Wales under the terms of the 1267 Treaty of Montgomery and Gruffydd was confined to his castle for the rest of his life.

Marriage

He married Emma (1224 – c. 1278), daughter of Lord Henry de Audley and Bertrade Mainwaring, members of the House of Stanley. His brother-in-law, Sir James Audley, was Chief governor of Ireland from Dublin Castle, and a companion of Richard of Cornwall, King of the Romans. Longespée's brother, William, also married Maud de Clifford, granddaughter of the prince of North Wales, Llywelyn ab Iorwerth.

Death and issue

He died in 1269 (or 1270) leaving issue:
