During c. 400 AD-450 AD, the time period immediately after the Romans left Britain, but before the Anglo-Saxons arrived, modern-day County Durham may have formed a part of the Brythonic kingdom ''Bryneich''. By the mid 6th century, during the Anglo-Saxon period, the Brythonic kingdom ''Bryneich'' had become the Anglian kingdom ''Beornice'', or Bernicia, with the first recorded king being Ida, whose reign lasted from approximately 547 AD-559 AD. By c. 605 AD, modern-day County Durham lay within the heart of the Anglian kingdom [[Northumbria]] after Ida's grandson Æthelfrith had merged Bernicia by force with its southern neighbour Deira which, ruled from Eoforwic (modern-day [[York]]), was located roughly between the rivers Tees in the north and [[River Humber|Humber]] in the south (covering approximately the modern-day [[North Riding of Yorkshire|North]] and [[East Riding of Yorkshire|East Ridings of Yorkshire]]). The overwhelming majority of the modern-day County Palatine's place-names are of [[Old English]] origin, and thus were coined in the Anglian period (late 5th-mid 11th centuries).
