Dubnovellaunus
Dubnovellaunus or Dumnovellaunus was the name of at least one, and possibly several kings of south-eastern Britain in the late 1st century BC/early 1st century AD, known from coin legends and from a mention in the Res Gestae Divi Augusti.
Dubnovellaunus is the name of a king who, based on coin distribution, appears to have ruled over Kent east of the River Medway. He was the first king of the Cantiaci to issue inscribed coins: some of his coins appear to date from as early as 40-30 BC. Towards the end of the 1st century BC he seems to have been succeeded by a king called Vodenos or Vosenios, although it is possible the two kings' reigns were contemporary or overlapped.
A king called Dubnovellaunus succeeded his father Addedomarus as king of the Trinovantes ca. 10-5 BC and ruled for several years before being supplanted by Cunobelinus of the Catuvellauni.
In the Res Gestae Divi Augusti, a British king called Dumnovellaunus appears, alongside Tincomarus of the Atrebates, as a supplicant to Augustus around AD 7.
