Madog ap Llywelyn

Madog ap Llywelyn (died after 1312) was the leader of the Welsh revolt of 1294–95 against English rule. The revolt was surpassed in longevity only by the revolt of Owain Glyndŵr in the 15th century. Madog belonged to a junior branch of the House of Aberffraw and was a distant relation of Llywelyn ap Gruffudd, the last recognised native Prince of Wales.

Madog was the son of Llywelyn ap Maredudd, the last vassal Lord of Meirionydd who had been deprived of his patrimony in 1256 for opposing the Prince of Wales, Llywelyn ap Gruffudd, at the Battle of Bryn Derwin. Llywelyn ap Maredudd had gone into exile in England where he received a pension from the English crown, until June 1262 when he reconciled with the Prince of Wales. He died in a skirmish fighting for the Welsh in April 1263. His eldest son, Madog, who may have been born in exile, is known to have received substantial monetary gifts from King Edward I of England in 1277, and used this money to sue the Prince of Wales in 1278 in an attempt to have his father's cantref of Meirionydd returned to him. It appears that Madog returned to Gwynedd after the death of Llywelyn ap Gruffudd in 1282, and received lands from the King of England in Anglesey.

On Michaelmas (29 September) 1294, Madog put himself at the head of a national revolt in response to the actions of new royal administrators in north and west Wales and the imposition of taxes such as that levied on one fifteenth of all moveables. As a royal prince descended directly from Owain Gwynedd and the fifth cousin of the last Prince of Aberffraw (Dafydd ap Gruffudd, the executed brother of Llywelyn), Madog declared himself to be the lawful successor and assumed the royal titles of his predecessors including that of Prince of Wales (an example of which can be seen in the so-called Penmachno Document). The uprising had been planned for months and attacks occurred on the same day across Wales. While Madog acted in the north the attacks in mid and south Wales were led by Cynan ap Maredudd, Maelgwn ap Rhys, and Morgan ap Maredudd of Gwynllwg in Glamorgan. The rebel leaders hoped that by the end of September King Edward and most of his forces would be in France on a planned campaign. However, due to bad weather Edward's army had not yet sailed and he quickly cancelled the French campaign to deal with the Welsh uprising.
