Wledig

The Welsh title [G]wledig, archaically Gwledic or Guletic and Latinised Guleticus, is defined as follows: "lord, king, prince, ruler; term applied to a number of early British rulers and princes who were prominent in the defence of Britain about the time of the Roman withdrawal; (possibly) commander of the native militia (in a Romano-British province)". It was a rare title, denoting someone who ruled over a specific territory, and was used in Great Britain during the century after the end of Roman rule. There were at least three men who were given this title: Cunedda, Macsen (the Welsh name for Western Roman Emperor Magnus Maximus), and Emrys (the Romano-British war leader Ambrosius Aurelianus), although there were about ten individuals given this title in the Oxford Red Book of Hergest. Another known person with this title was Amlawdd Wledig (almost certainly mythological Welsh king sometimes claimed to be the maternal grandfather of King Arthur). Some sources indicate that in early Welsh literature, this title was given to the individual with the supreme power in Britain, but by medieval times the term had come to loosely mean "ruler" or "prince".

Etymology

The name derives from gwlad ("country, land, region") and the suffix '-ig', a diminutive which often forms a specific noun from a more abstract one.
