Before the Conquest of Wales, completed in 1282, Wales consisted of a number of independent kingdoms, the most important being Gwynedd, Powys, Deheubarth (originally Ceredigion, Seisyllwg and Dyfed) and Morgannwg (Glywysing and Gwent). Boundary changes and the equal division of patrimony 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 of the kingdoms are listed below. The only person known to have ruled all of Wales was Gruffydd ap Llywelyn (c. 1010-1063), a prince of Gwynedd who became King of Wales from 1055 to 1063.
