Holderness, the Vale of York, and the Vale of Pickering are three fairly typical marshland areas, and all three were originally wasteland. Medieval reclamation improved the siltlands of each area for arable and pasture, but the peatlands remained waterlogged for three-quarters of the year and were used mainly for summer pasture and as sources of fish, fowl and fuel, until the mid-eighteenth century. Between 176o and 1900 they were drained by the use of large-scale engineering methods. Improvements were greatest in Holderness, while in the other two areas much still remained to be done in the twentieth century. There are various reasons both for the similarities and differences in the drainage history of the three regions, and for the differences between these regions and the other marshland areas of England and Wales. Location, size, the existence or otherwise of a frontage on tidal water and the resulting existence of a 'Court of sewers' - farming systems, patterns of ownership, navigation interests, and the influence of settlements, as well an the physical geography, are all shown to have had an influence both on the pace of improvement and on the pattern of drains developed. The present geography of the three areas shows clear traces of the earlier stages In their history.

This study has attempted to examine third and fourth century pottery supply in northern England together with other aspects of pottery assemblages in the region. The pottery kilns of the East Yorkshire industries have been characterised by neutron activation analysis which has proved reasonably successful in discriminating between them. Neutron activation analysis has also been utilised to attempt to check visually identified fabric groups and to help isolate other fabrics. This has been of varying success. Quantified data has been collected from 15 sites across the north and the limited published quantitative data have been utilised to examine the distribution, marketing and competition between fabric types in the region. Examination of functional variations through time between different types of site has also been undertaken as has that of variations in the quantity of finewares through time and between different types of site together with an attempt at quantifying decoration and examining trends in this. Pottery supply to the northern frontier area would seem to have been organised by different mechanisms in different periods. In the second century much of the pottery used on the frontier would appear to have been produced by the military themselves whilst in the third century and earlier fourth century free market mechanisms would seem to have operated, but in the late fourth-early fifth centuries some form of 'military contract' would appear to have taken over supply. Functional variations between different types of site have been identified with rural sites, turrets and Signal Stations sharing a major emphasis on the jar as the basic ceramic form and more complex settlement types having more diversified functional groups. The distribution of finewares also seems to be concentrated on more complex settlement types. It is apparent that there are consistent differences between the East Yorkshire region and the rest of the study area which may well reflect differences extending back into the Iron Age. Similarly there seem to be indications of some 'de-Romanisation' in late Roman assemblages but this does not develop in the fifth century, when nearly all the strands of evidence of Romano-British material culture disappear very rapidly.

There is an ongoing debate concerning the nature of warfare and violence in the Iron Age of Britain. Interpretations regarding material remains from this period fluctuate between classifying instruments of violence (i.e. swords, spears, hillforts) as functional tools of war and as ritual symbolic devices. Human skeletal remains provide the most unequivocal evidence for violent encounters, but were often missing from these debates in the past. This thesis addresses this lack of treatment by analyzing the patterns of traumatic injuries at sites from two distinct regions in Iron Age Britain (East Yorkshire and Hampshire). The human remains from these sites show clear markers of interpersonal violence. When the remains are placed in context with the mortuary treatment, it is evident that violence and ritual were inextricably linked. In East Yorkshire, combat may have been ritualized through duelling and competition performance. In Hampshire, individuals with perimortem injures are often found in special deposits such as pits, ditches and domestic areas, suggesting their use in ritual processes that distinguish them from the general population. This provides a basis for understanding warfare and violence during the Iron Age of Britain and how communities negotiated the social tensions caused by violent interactions.

During the first millennium BC, the people of the chalk landscapes of the Yorkshire Wolds began carving up their world with monumental linear earthworks. This project explores the meanings of the later prehistoric boundary systems of the Yorkshire Wolds. It writes a biography of the linear earthwork landscapes of the north-central Wolds, using geographic information systems (GIS), original fieldwork and theories of agency and memory. Tracing the construction, use and modification of particular linear earthworks, it examines how these monuments would have related to other features in the landscape, and how they could have exercised agency within networks of interconnected people, animals, objects and other places. Finally, the project attempts to situate these boundary systems within the larger context of Late Bronze Age and Iron Age society in order to understand how the later prehistoric people of East Yorkshire would have experienced their world. Taking a biographical approach to landscape and allowing linear earthworks to become the protagonists of this narrative, the project charts the life histories of the earthworks at Wetwang-Garton Slack and Huggate Dykes and investigates the collective authorship of the wider landscape. To understand the rural, monumental landscapes of the Wolds, we must consider the agency of not only people, but also of animals and of monuments themselves. By focussing on the relationships which bound together linear earthworks and other agents, we can begin to understand the ways in which monumentalised landscapes both reflected and generated the cosmologies of prehistoric communities.

This thesis reports an investigation of Iron Age diet in Britain using carbon and nitrogen stable isotope data obtained from skeletal material from four locations across England and southern Scotland. Both human and animal bone Collagen has been analysed from Wetwang in East Yorkshire and other sites in East Lothian, Hampshire and Cornwall. Animal bone from Dorset has also been included. The aims of the study were to characterize British Iron Age diet in general isotopic terms and also to provide a contextual base for future analysis which allows an understanding of both inter- and intra-site variation in such data for this and other periods. The comparisons across the locations allowed consideration of geographical variability within England and southern Scotland and included material from coastal sites (Cornwall and East Lothian), from sites with easy access to rivers and estuaries (Hampshire) and an inland site where access to water would have been more difficult (Wetwang). All human groups were consuming high levels of animal protein and there was very little evidence for the consumption of aquatic resources. There was significant variation in 815N values between the locations, which was reflected both in the humans and the herbivores, such that it is likely to be related to environmental rather than to dietary differences. Intra-site group comparisons at Wetwang showed very little variation within the cemetery population IM according to age, sex, subjective status category or site phase. The data were very consistent within the populations, although those for Hampshire displayed more variation in nitrogen.
