Hawarden and Rhuddlan (which had recently been built to strengthen Edward's control of coastal Perfeddwlad), instigating sympathetic outbreaks of anti-English violence in the rest of wales. Llywelyn decided to support his brother. Edward's reaction was fierce, the revolt was crushed, Llywelyn was killed in battle, and Dafydd was caught, tried by Edward's parliament, and (having been convicted) hung, drawn, and quartered. Gwynedd was abolished, its relics and assets taken to Westminster, and Dafydd's sons were imprisoned for life. Following the consequent Statute of Rhuddlan, in 1284, Rhos and Rhufoniog were combined to form the new lordship of Denbigh and conferred upon Henry de Lacy, earl of Lincoln; Dyffryn Clwyd became the lordship of Ruthin and was granted to Reginald de Grey; Tegeingl became the lordship of Englefield and the main body of the proto-county of Flint, under the aegis of the palatinate of Chester (Englefield had only been Welsh since the late 13th century, prior to which it had been part of Cheshire).
