The Statute of Rhuddlan (Welsh: Statud Rhuddlan, Welsh pronunciation: [ˈr̥ɨðlan], approximately RIDH-lan), also known as the Statutes of Wales (Latin: Statuta Vallie) or as the Statute of Wales (Statutum Vallie or Statutum Valliae), provided the constitutional basis for the government of the Principality of North Wales from 1284 until 1536. The statute was enacted on 3 March 1284 and promulgated on 19 March at Rhuddlan Castle in North Wales, after careful consideration of the position by Edward I.
The Prince of Gwynedd had been recognised by the English Crown as Prince of Wales in 1267, holding his lands with the king of England as his feudal overlord. It was thus that the English interpreted the title of Llywelyn ap Gruffudd, Lord of Aberffraw, which was briefly held after his death by his successor Dafydd ap Gruffudd. This meant that when Llywelyn rebelled, the English interpreted it as an act of treason. Accordingly, his lands escheated to the king of England, and Edward I took possession of the Principality of Wales by military conquest from 1282 to 1283. By this means the principality became "united and annexed" to the Crown of England.
