The Treaty of Aberconwy, a humiliating settlement forced on Llywelyn ap Gruffudd by King Edward I of England, brings a temporary end to the Welsh Wars.
Treaty of Aberconwy
The Treaty of Aberconwy was signed on the 10th of November 1277, and was made between King Edward I of England and Llywelyn ap Gruffudd, Prince of Wales. It followed Edward's invasion of Llywelyn's territories earlier that year. The treaty re-established peace between the two but also essentially guaranteed that Welsh self-rule would end upon Llywelyn's death and represented the completion of the first stage of the Conquest of Wales by Edward I.
Llywelyn ap Gruffudd
Llywelyn ap Gruffudd, also known as Llywelyn II and Llywelyn the Last, was Prince of Gwynedd, and later was recognised as the Prince of Wales from 1258 until his death at Cilmeri in 1282. Llywelyn was the son of Gruffudd ap Llywelyn ap Iorwerth and grandson of Llywelyn ab Iorwerth, and he was one of the last native and independent princes of Wales before its conquest by Edward I of England and English rule in Wales that followed, until Owain Glyndŵr held the title during his rebellion of 1400–1415.
Edward I of England
Edward I, also known as Edward Longshanks and the Hammer of the Scots, was King of England from 1272 to 1307. Concurrently, he was Lord of Ireland, and from 1254 to 1306 ruled Gascony as Duke of Aquitaine in his capacity as a vassal of the French king. Before his accession to the throne, he was commonly referred to as the Lord Edward. The eldest son of Henry III, Edward was involved from an early age in the political intrigues of his father's reign. In 1259, he briefly sided with a baronial reform movement, supporting the Provisions of Oxford. After reconciling with his father, he remained loyal throughout the subsequent armed conflict, known as the Second Barons' War. After the Battle of Lewes, Edward was held hostage by the rebellious barons, but escaped after a few months and defeated the baronial leader Simon de Montfort at the Battle of Evesham in 1265. Within two years, the rebellion was extinguished and, with England pacified, Edward left to join the Ninth Crusade to the Holy Land in 1270. He was on his way home in 1272 when he was informed of his father's death. Making a slow return, he reached England in 1274 and was crowned at Westminster Abbey.
