During the early medieval period eastern England was occupied by two major Anglo-Saxon kingdoms—the East Saxons and East Angles—alongside a region that Bede referred to as ‘Middle Anglia’. There has been a widespread assumption that Essex (‘the East Saxons’) and Suffolk and Norfolk (the ‘South Folk’ and ‘North Folk’ of East Anglia) were direct successors to these Anglo-Saxon kingdoms (e.g. Carver 1989, fig. 10.1; 2005, 498; Yorke 1990, 46, 61; Warner 1996, 4, plate 1; Pestell 2004, 12; Chester-Kadwell 2009, 46; Kemble 2012, 8; Gascoyne and Radford 2013, 176; Reynolds 2013, fig. 4), which would imply a strong degree of territorial continuity from at least the early medieval period through to the present day. There is, however, a recognition in the Regional Research Framework that regional differences within early medieval society across eastern England have seen little investigation (Medlycott 2011b, 58), something that the following chapters hope to address. This chapter will explore the documentary evidence for these early medieval kingdoms and their relationship to later counties, before turning to the archaeological evidence for Anglo- Saxon immigrants and their relationship to the native British population in Chapters 8–10. The clear differences between the Northern Thames Basin, East Anglia, and the South East Midlands that are still evident during the seventh to ninth centuries are outlined in Chapter 11. Finally, Chapter 12 explores the boundaries of the early medieval kingdoms, and in particular the series of dykes constructed in south-eastern Cambridgeshire.Table 7.1 provides a timeline of key historical dates for early medieval England, and key developments within the archaeological record. The earliest list of territorial entities is the Tribal Hidage. The original document has been lost—it only survives in a variety of later forms—but it is thought to have been written between the mid seventh and the ninth centuries (Hart 1970; 1977; Davies and Vierck 1974, 224–7; Yorke 1990, 10; Blair 1991, 8; 1999; Harrington and Welch 2014, 1). The Tribal Hidage lists at least thirteen peoples in and around eastern England, some of whom clearly occupied quite extensive areas, such as the East Angles (assessed as 30,000 hides), East Saxons (7,000 hides), and the Cilternsætna (4,000 hides).
