This thesis provides an analysis of the royal itineraries of King John, Henry III and Edward I, and examines the influences that acted upon these itineraries as well as the impact they had upon thirteenth-century England. Throughout this thesis the thirteenth-century English royal itinerary is placed within the context of other English royal itineraries. 2 Part I is divided into seven chapters. Chapter one sets out why the itineraries should be analysed, introduces the questions about the itineraries that this thesis seeks to answer, and considers the hypotheses that historians have made regarding these questions. Chapter two surveys the sources upon which the itineraries are based, considers how the itineraries were constructed, and sets out the rules of analysis which have been used in this thesis. Chapter three examines the logistics of the royal itinerary, such as planning and organization. Chapters four, five and six relate to the royal itinerary for John, Henry III and Edward I respectively. These chapters provide the overall analysis for the royal itinerary-including information on rates of travel, distance, lengths of stay and the favourite residences and regions of each king. They also examine the motivations that governed the itineraries, such as aspects of both routine and extraordinary royal government, piety and pleasure. Chapter seven focuses on the adaptation and impact of the itineraries, including the changes in the relationship between the king and his subjects and the impression the royal itinerary made upon contemporary chroniclers and writers. Chapter eight provides an overview of the conclusions reached. Part II is formed of an extended Appendix. This appendix presents the full analysis for each of the years studied in this thesis (1199-1226, 1234-41, 1244-52, 1274-6, 1278, 1280-1, 1285, 1290-3 and 1305), as well as overall information on the locations visited by each king, which formed the basis of the analysis discussed in Part I.
