Treaty of Aberconwy

The Treaty of Aberconwy was signed on the 10th of November 1277,[1] and was made between King Edward I of England and Llywelyn ap Gruffudd, Prince of Wales.

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.

[3] They were married by proxy in 1275, but when Eleanor sailed from France to meet Llewelyn, Edward hired pirates to seize her ship; she was imprisoned at Windsor Castle.

Edward now enjoyed a degree of direct control in the native Welsh areas which no previous English king had achieved.

[8] Llywelyn was killed at the Battle of Orewin Bridge in December 1282,[9] and Edward's conquest of Wales was completed with Dafydd's capture in June 1283.
