Because of the sparse evidence for the period, many interpretations are possible.

 in 402, and bulk coin payments ceased around this time. In 406 the army in Britain revolted, electing three successive "tyrants" the last of whom took the remaining troops to the continent. He became a joint emperor as Constantine III but was defeated and subsequently executed in 411. Meanwhile there were barbarian raids on Britain in 408 but these seem to have been defeated. After 410 Honorius apparently sent letters to the cities of Britain telling them to fend for themselves, though this is sometimes disputed. The withdrawal of Roman legions did not put an end to the Roman culture of the "lost province", which still remained part of the Roman cultural world, as Britons self-identified as Roman.

From the middle of the fifth century the Germanic raiders altered their intentions towards the island and began to settle in the eastern river valleys. Later civil wars seem to have broken out, which have been interpreted either as being between pro-Roman and independence groups or between "Established Church" and Pelagian parties (Myres 1965, Morris 1965), a class struggle between peasants and land owners (Thompson 1977, Wood 1984) and a coup by an urban elite (Snyder 1988).

 recently writing that England was 'submerged by an Anglo-Saxon current which swept away the Romano-British.'

The traditional view has been deconstructed to a degree (a considerable degree in some circles) since the 1990s. At the centre of this is a re-estimation of the numbers of Anglo-Saxons arriving in Britain during this period. 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. The Anglo-Saxons are suggested to have formed a ruling elite with acculturisation of the local population if the lowest of figures are used. Thus some "Saxon" graves may be of Britons though many scholars would disagree with this interpretation.

age to Britain had dried up by the early fifth century, meaning administrators and troops were not getting paid. All of this, he argues, led the British people to rebel against Rome. Both of these arguments are open to criticism, though as yet no further developments have been made in understanding why the end of Roman Britain occurred.

However, the violent nature of the period should not be overlooked, and it is likely that this period was a time of endemic tension, alluded to in all of the written sources. This may have led to the deaths of a substantial number of the British population. There are also references to plagues. Laycock (Britannia the Failed State 2008) suggests tribal conflict, possibly even starting before 410, may have sliced up much of Britain and helped destroy the economy. The evidence from land use suggests a decline in production, which might be a sign of population decline.

Background

Slaves were the engine of both the economy and the army in the Roman Empire. Estimates for the prevalence of slavery in the Roman Empire vary, with some estimating that approximately 30% of the population of the Empire in the 1st century was enslaved. The Germanic region was one of the main sources of slaves. The business of selling slaves was mostly carried out by wholesale dealers, who followed the Roman armies. There was a reduction of sources for procurement of slaves after the expansion phase, and afterwards (around 210 AD) there was a significant increase of piracy

Under Diocletian, the Ius Colonatus was a reform of the slavery system introduced around 286 AD (similar to later Serfdom

The Hospitalitas reform involved the granting of a third of the land (or fees) of a region to barbarians who had invaded those lands.
