as a violent event. The toponymic and linguistic evidence was also considered to support this interpretation, as very few British place names survived in eastern Britain, very few British Celtic words entered the Old English language and the Brythonic language and peoples migrated from south-western Britain to Armorica, which eventually became Brittany. This interpretation particularly appealed to earlier English historians, who wanted to further their view that England had developed differently from mainland Europe, with a limited monarchy and love of liberty. This, it was argued, came from the mass Anglo-Saxon invasions. While this view was never universal – Edward Gibbon believed that there had been a great deal of British survival – it was the dominant paradigm. Though many scholars would now employ this argument, the traditional view is still held by many other historians, Lawrence James writing in 2002 that England was "submerged by an Anglo-Saxon current which swept away the Romano-British." The traditional view has been partly deconstructed (considerably in some circles) since the 1990s, with a reduction in the numbers of Anglo-Saxons believed to have arrived in Britain. A lower figure is sometimes accepted, which would mean that it is highly unlikely that the existing British population was substantially displaced by the Anglo-Saxons. If fewer Anglo-Saxons arrived, it is proposed that they formed a ruling elite, with acculturation of the local population. Thus some "Saxon" graves may be of Britons, though many scholars disagree. Two genetic studies published in 2016, using data from ancient burials found in Cambridgeshire, Yorkshire and Durham, found that the ancestry of the modern-day English population contained substantial contributions from both Anglo-Saxon and Celtic peoples. End of Roman Britain Various dates have been proposed to mark the end of Roman Britain, including the end of Roman currency coinage importation in 402, Constantine III's rebellion in 407, the rebellion mentioned by Zosimus in 409, and the Rescript of Honorius in 410. Unlike modern decolonisation, the dating of the end of Roman Britain is complex, and the exact process is unknown. There is some controversy as to why Roman rule ended in Britain. The view first advocated by Theodor Mommsen was that Rome left Britain. This argument was substantiated over time, most recently by A.S. Esmonde-Cleary. According to this argument, internal turmoil in the Roman Empire and the need to withdraw troops to fight off barbarian armies led Rome to abandon Britain. It was
