An important contribution to a growing body of scholarship on the internal, social, economic, and religious structures of South Asian mercantile, moneylending, and corporate communities a masterful argument for studying economic and business history through the lens of Muslim religious authority, legal practice, and identity. -- Amanda Lanzillo * Developing Economies * This is an audacious scholarly conversation between received categories of classical political economy and South Asian Islam that is likely to provoke debate among specialists in the field. For the general student of history however, it is a book that demands close attention for its outstanding contributions to the craft, both in its expansive approach toward the archive as in its deft interweaving of religion, culture and politics within the complex terrain of capitalist enterprise and law. The structure, prose and narrative richness of the book are likely to ensure a life for it outside the scholarly niche of economic history. -- Madhumita Mazumdar * Telegraph India * A rich historical account of Gujarati Muslim business communities, emphasising their diverse experiences, achievements, and challenges throughout the nineteenth and twentieth centuriesthe concept of corporate Islam is a much needed contribution to understand the emergence of global Capitalism especially from the perspective of the global South. -- Gijsbert Oonk * Business History * Challenges the colonial image of these three groups as rapacious migratory birds who replicated the voracious capitalism of the East India Company, and later European colonizers, to show that they instead planted deep roots wherever they migratedmakes a significant contribution to the modern history of these communities. -- Arwa Hussain * Reading Religion * No Birds of Passage is a brilliant and strikingly innovative contribution to the history of trade and diaspora in the Indian Ocean. Based on an impressive array of sources, it tells a compelling story about the emergence of a distinctive form of Muslim capitalism that continues to shape the region today. -- Sunil Amrith, author of Unruly Waters The intersection of community, caste, and capitalism is a matter of abiding interest for South Asian historians of both the early modern and modern periods. Michael OSullivans well-documented and closely argued work on Gujarati Muslim entrepreneurs over two centuries is a significant intervention in this field. It merits a wide readership, and is also certain to provoke debates well beyond the confines of South Asian studies. -- Sanjay Subrahmanyam, author of Europes India This sophisticated and fine-grained case study is a model of how to write revisionist economic histories that resonate with the experiences of people in most of the world. No Birds of Passage succeeds precisely because its conceptual apparatus is built on giving endogenous institutions their due, bringing together a range of sources in multiple languages, and openly embracing paradoxes without which this story of Muslim capitalism would have remained illegible. This is an exciting contribution to the burgeoning global histories of capitalism. -- Mrinalini Sinha, author of Specters of Mother India A major contribution to South Asian history. OSullivans sweeping account of Gujarati Muslim business communities is more than a business history. It is an impressive examination of how the Khojas, Bohras, and Memons reshaped community corporate identities through their interactions with the colonial state, Indian nationalism, Muslim politics, and postcolonial regimes. -- Douglas E. Haynes, author of Small Town Capitalism in Western India This is a landmark work of scholarship, meticulously recovering the transimperial worldviews of Gujarati Muslim business communities both before and after the age of imperial capitalism. Attentive to historical asymmetries of race and sovereignty, OSullivans dynamic and capacious study will inform future work on imperial and postcolonial economic history as well as on the social-religious logics of capital accumulation. -- Manu Goswami, author of Producing India
