In his review of South East Britain in the later Iron Age, Hill (2007, 16) observed that ‘Since the 1980s, little attention has been given to large-scale social explanations and narratives in British Iron Age archaeology. Debates over core–periphery models, the interpretation of hillforts, and the nature of social organization, were—for good reason—eclipsed by a focus on the symbolic meanings of space, structured deposition, and ritual.’ He goes on to argue that British archaeology is in need of more ‘straightforward storyboards’ around which data can be arranged (Hill 2007, 16), and Brudenell (2012, 52) has similarly noted how ‘close-grained understandings have often been won at the expense of broader pictures . . . [and that] with a few exceptions, recent approaches have atomized the study of later prehistoric society, focussing on the specifics of the local social milieu at the expense of broader scales of social analysis’. There have been some ‘big picture’ studies—most notably Cunliffe’s (1974; 1978; 1991; 2005) Iron Age Communities in Britain—but all too often studies of this period have focused on specific counties, types of site, or artefact, and it is noticeable how little systematic mapping of data there was in three recent collections of papers (Gwilt and Haselgrove 1997; Haselgrove and Moore 2007; Haselgrove and Pope 2007). This study, in contrast, aims to shed light on one important ‘storyboard’: the territorial structures within which communities built their landscapes. The written history of Britain begins in the first century BC when we first get insights into its political and territorial arrangements, although as this was a period when the island was becoming embroiled in the political instability caused by the expansion of the Roman world, the trends seen then may not reflect the longer-term patterns of territorial stability or instability that preceded it. In 54 BC, for example, Caesar describes how his major opponents were a civitas (usually translated as ‘tribe’) who had recently surpassed the neighbouring Trinovantes as the paramount group in South East Britain (Gallic War, 20–1; Dunnett 1975, 8; Moore 2011).
