THE ARABIAN SEAS IN THE SEVENTEENTH CENTURY Rene Barendse The object is to produce an expanded English version of my 1991 Ph.D.Thesis Koningen, Compagnieen en kapers De Arabische zeeen 1640-1700 (English version Kings, Companies and corsairs and corsairs in the Arabian seas 1640-1700). The study aims to provide a broad comparative account of the trade in the western Indian Ocean, considering European activities against the backdrop of "indigenous" commerce. On a theoretical level the study has three basic objectives: first, to show that the developments in a single region can not be understood without taking developments in the Arabian seas as a whole into consideration. Here I will focus on the concept of risk, protection and information as elements in the structure of costs to trade. Second, to study the pattern of economic shifts and fluctuation in the middle long-run, instead of the often exclusive attention bestowed either upon short-term (political) or upon the supposedly very long-run patterns of "traditional Asian trade". And third, on the one hand to break down the barriers between various "national" historiographies" regarding European expansion in the Indian Ocean, and on the other between the "orientalist" and "Europeanist" level of discourse on social and economic developments which are better understood as common intercontinental shifts. Within the scope of these broader theoretical concerns, I will present a large amount of new material from Dutch, Portuguese and Indian archives on a wide variety of themes relative to the history of the Indian Ocean, which are difficult to compress into short compass: these would range from the relative significance of bullion-flows and cash-crop production to the Indian and Persian agricultural economies to Brazilian shipping to Mozambique; from attempts to reform the Portuguese empire to Armenian trade to Astrakhan, or from the structure of government at Basra to the social significance of the idea of a pirate's republic in Madagascar to the seamen of New York. R.J. Barendse (1961) studied Modern History at the University of Amsterdam and History of the European Expansion at the University of Leiden. He obtained his Ph.D. at Leiden University in may 1991 with Koningen, Compagnieen en kapers, De Arabische zeeen 1640-1700.
