Overview

Anglo-Saxon England designates the Germanic-ruled polities of Britain from the 5th-century settlement to the Norman Conquest (1066); this entry covers its formation. Per Bede and the Anglo-Saxon Chronicle, the adventus Saxonum ("coming of the Saxons") is traditionally dated to around 449, when the British ruler Vortigern invited the brothers Hengist and Horsa as mercenaries against the Picts; they and their kinsmen then seized land for themselves in Kent, beginning the Germanic conquest. (Bede's tripartite scheme assigns Kent and Wight to the Jutes, the southern coast to the Saxons, and the north and midlands to the Angles.)

Decline and legacy

Over the 6th and 7th centuries a shifting group of kingdoms coalesced — later conventionally called the Heptarchy ("seven kingdoms"): Kent, Sussex, Wessex, Essex, East Anglia, Mercia, and Northumbria (the last formed from Deira and Bernicia), plus lesser polities. This was never a fixed set of seven equal states but a fluid landscape of overkings and sub-kings. Bede describes a succession of dominant rulers holding imperium over the others — later called bretwaldas ("Britain-rulers"). The Christianisation of the English began with the Gregorian mission of Augustine to Kent in 597 (from Rome) and the Ionan/Irish mission in the north, the two traditions reconciled at the Synod of Whitby (664). The period produced a rich vernacular literature (Beowulf), Latin scholarship (Bede, Aldhelm), and superb art (Sutton Hoo, the Lindisfarne Gospels). The historiographical debate over how far the "invasion" was mass migration versus elite dominance and acculturation (see entry 16) is central to understanding this formation.
