List of rulers in Wales facts for kids

Kids Encyclopedia Facts

This article is about the important leaders and rulers in Wales (called Cymru in Welsh) and nearby areas during the Middle Ages, from about the 400s to the 1500s. These rulers were kings or princes who led their own lands. Some also briefly ruled the whole Principality of Wales. Today, these lands are part of modern Wales and the Welsh Marches in England, both in the United Kingdom.

Before King Edward I conquered Wales in 1282, Wales was made up of many independent kingdoms. The most important ones were Gwynedd, Powys, Deheubarth, and Morgannwg. Because borders often changed, and lands were divided among heirs, very few princes ever ruled all of Wales.

Only one person is known to have ruled all of Wales as a single country: Gruffydd ap Llywelyn. He was a prince of Gwynedd who became King of Wales from 1055 to 1063. Later, between the 13th and 15th centuries, some Welsh princes claimed the title of Prince of Wales. This title is still used today, but it's usually given to the future kings or queens of England and Britain.

During the Middle Ages, Wales was a land of many kingdoms and ruling families. Smaller kingdoms like Ceredigion and Gwent started after Britain was no longer part of the Roman Empire, around the late 400s. By the time the Normans invaded Wales in the 1000s, most of these smaller lands had joined together or become part of four main Welsh Kingdoms.

These four major kingdoms were Gwynedd, Powys, Deheubarth, and Morgannwg. Deheubarth was formed later by combining Ceredigion, Dyfed, and Ystrad Tywi. Some smaller kingdoms remained independent but were later taken over by the Anglo-Normans in the 1200s.

One of the last Welsh ruling families came from Powys. This kingdom was divided into Powys Wenwynwyn and Powys Fadog in the 1200s. Later, Owain Glyndŵr became the last Welsh ruler from a royal family in Wales. He rose to power in Powys Fadog in the early 1400s as a Prince of Wales.

Welsh Lordships (1000s–1500s)

After the Norman invasion around the 1000s, some Welsh areas were ruled by "Lords" instead of kings. These lords were often direct descendants of the old Welsh kings. Some of these lordships lasted even after Edward I conquered Wales in the 1300s, and a few continued into the time of the Principality of Wales.
