List of rulers in Wales facts for kids

Kids Encyclopedia Facts

This is a list of rulers in Wales (Welsh: Cymru; and neighbouring regions) during the Middle Ages, between c. 400s – 1500s. The rulers were monarchs who ruled their respective realms, as well as those who briefly ruled the Principality of Wales. These former territories are now within the boundaries of modern-day Wales and the neighbouring Welsh Marches in England (both in the United Kingdom).

Before the Conquest of Wales, completed in 1282, Wales consisted of several independent realms, the most important being Gwynedd, Powys, Deheubarth (originally Ceredigion, Seisyllwg and Dyfed) and Morgannwg (Glywysing and Gwent). Boundary changes and the custom of dividing patrimonies between heirs meant that few princes ever came close to ruling the whole of Wales.

The names of those known to have ruled over one or more areas are listed below. Boundaries changed frequently. The only person known to have ruled all of Wales as a modern territory was Gruffydd ap Llywelyn (c. 1010–1063), a prince of Gwynedd who became King of Wales from 1055 to 1063. However, some Welsh princes sporadically claimed the medieval title of Prince of Wales between the 13th to 15th centuries. The title remains in use, but is usually given to heir apparents of English and British monarchs.

History of the medieval kingdoms in Wales

Wales during the medieval age was a land of kingdoms and dynasties. Petty kingdoms, such as Ceredigion and Gwent, were established some time after Britain ceased to be part of the Roman empire in the late 5th century. By the time of the Norman invasion of Wales in the 11th century, most of these realms were combined or incorporated into greater territories, thus making up the four major Kingdoms of Wales. Those Kingdoms were Gwynedd, Powys, Deheubarth, and Morgannwg. Unlike the others, Deheubarth was formed later by the merging of Ceredigion, Dyfed, and Ystrad Tywi. Some minor (petty) kingdoms stayed independent from the big four kingdoms, only to be taken over by the Anglo-Normans in the 13th century, such as Rhwng Gwy a Hafren, and Meirionnydd, and others. Of the major kingdoms, Powys' 13th-century division of Wenwynwyn and Fadog were one of the final surviving Welsh dynasties until after the Edwardian conquest of Wales. Later, Owain Glyndŵr became the final Welsh ruler from royalty in Wales, he emerged in Powys Fadog during the early 15th century as a Prince of Wales.
