Second Dynasty of Gwynedd

The Second Dynasty of Gwynedd or Merfynion, sometimes known as the House of Aberffraw, was a dynasty which ruled over Gwynedd with minor interruptions from the ninth to thirteenth centuries. The family was deposed in 1283 with the conquest of Wales by Edward I, which resulted in the execution of the last ruler of Gwynedd, Dafydd ap Gruffudd on October 3 of that year.
