Director of Central Library Services and Goldsmiths' Librarian 1 August 1978 fS i '-j I I 1 1 n Selected phases of the historical pteograDhy of ma;ior eastern African ports by Bashir Ahmed Datoo Thesis presented for the Decree of Doctor of Philosophy at the University of London August 1968 J “ T'l 2 I Abstract Before the nineteenth century the Bast African coast formed an inte. ral part of the Indian Ocean commercial system, and because of changing internal and external space relations, successive hi.ctorical epochs sav; the emergence of vadely different port hierarchies.The concept of an 'open system' - vdth its progression from movements to trade-routes, nodes, hierarchies to a model - provides a fruitful approach for the evolution of port activity and allows the 'cut' to be made just as much vath routes as with ports.Owing to the limited extent of overland connections prior to the seventeenth century, epochs of change in the pattern of port development were marked by the establishment of new overseas connections.At the commencement of the Christian era trade contacts were v;ith the 3ed Sea, but as ea:item Africa then had only two unrelated ports, discussion stops short of a hierarchy. During the Kiddle Ages commercial intercourse began with the Persian Gulf, to be followed a fe\; centuries later by direct links with north-west India, and the succession of ports over this period of six centuries enables the construction of a model of the spatial patterns of port locations.V;ith the breakthrough of the Portuguese into the Indian Ocean at the end of the <^ifteenth century J I I I ra S 5 1 I g t a newelement in space relations v/as introauced, v/hose impact is analysed ajjainst the last phase of the model, jiast .'ifrica became a backwater in the subsequent centuries, but under the combined influence of Omani commercial stimulus and French slaving interest there vjas a r.vival of prosperity from the second half of the eighteenth century, v.hich calls for trade-routes to be followed tlirough afresh to the build-up of a new port hierarchy, This more or less endured until the late nineteenth century which, because of the advent of steamships and railways, marked the end of an era in port development that had been characterisfed by changing port hierarchies associated vdth varying alignments of trade-routes. 4 1 Contents Page Abstract 2 List of figures 6 Glossary 8 Abbreviations 10 Acknowledgments 11 Chapter 1 Introduction: The Geographical Background and the Conceptual Framework for an Historical Geography of eastern African Ports 12 Chapter IIThe Geography behind the Periplus; Port Development in the early second century A.D. 37 Evolution of the Graeco-Homan trade-route in the Arabian Sea 38 Identification of Opone and Rhapta 51 The cinnamon trade of Opone 63 The ivory trade of Bhapta 69 Chapter IIIThe Evolution of Spatial Patterns of Port Locations in the Middle Ages 76 Phase one: Dispersed pattern of ports79 Phase two: Interconnection and concentration 90 Phase three: Feeders and centralisation 107 Phase four: Diffusion of port activity134 Chapter IVThe Superimposition of Portuguese Establishments on the Indigenous Pattern of Ports in the early Sixteenth Century154 Portuguese fortresses at Sofala and Kilwa156 Portuguese factories at Mozambique and Malindi 168 The Crown's turnover in gold 179 -J 5 I The Portuguese contraband in gold 183 Swahili spatial readjustments189 Proposals to counter the Swahili clandestine traffic 202 Chapter V Port Hierarchy in the later part of the Eighteenth Century 20?
