Richard L. Kagan and Philip D. Morgan, eds. (2009). Atlantic Diasporas: Jews, Conversos and Crypto-Jews in the Age of Mercantilism, 1500-1800. Baltimore: The Johns Hopkins University Press. ISBN-13: 978-0-8018-9034-5. This edited collection of essays presents its readers with the fruits of the first Lavy Colloquium, which was held at Johns Hopkins University (Baltimore, U.S.A.) in March 2005 with the theme of "Atlantic Jewry in the Age of Mercantilism." It seeks, in the words of the editors Richard Kagan and Philip Morgan, to contribute to "the convergence of two streams of scholarly endeavour: one focused on early modern Atlantic history and the other on so-called Port Jews" (p. vii). These two streams have indeed developed in parallel directions although great efforts have been made in the past to link them. As early as 1985, Jonathan Israel published his magisterial European Jewry in the Age of Mercantilism, 1550-1750 (Clarendon Press) and the subject has witnessed a surge of academic interest and research in these two streams during the past decade. The study of "Port Jews" has most notably been advanced by two absorbing collections of essays on this topic published under the editorial direction of Professor David Cesarani: Port Jews and Jewish Communities in Cosmopolitan Maritime Trading Centres, 1550-1950 (Routledge, 2002) and, edited in collaboration with Gemma Romain, Jews and Port Cities 1590-1990: Commerce, Communities and Cosmopolitanism (Vallentine Mitchell & Co Ltd, 2006).
