The Indian Ocean was global long before the Atlantic, and today the countries bordering the Bay of Bengal―India, Bangladesh, Burma, Sri Lanka, Thailand, and Malaysia―are home to one in four people on Earth. Crossing the Bay of Bengal places this region at the heart of world history for the first time. Integrating human and environmental history, and mining a wealth of sources, Sunil Amrith gives a revelatory and stirring new account of the Bay and those who have inhabited it. For centuries the Bay of Bengal served as a maritime highway between India and China, and then as a battleground for European empires, all while being shaped by the monsoons and by human migration. Imperial powers in the nineteenth century, abetted by the force of capital and the power of steam, reconfigured the Bay in their quest for coffee, rice, and rubber. Millions of Indian migrants crossed the sea, bound by debt or spurred by drought, and filled with ambition. Booming port cities like Singapore and Penang became the most culturally diverse societies of their time. By the 1930s, however, economic, political, and environmental pressures began to erode the Bay’s centuries-old patterns of interconnection. Today, rising waters leave the Bay of Bengal’s shores especially vulnerable to climate change, at the same time that its location makes it central to struggles over Asia’s future. Amrith’s evocative and compelling narrative of the region’s pasts offers insights critical to understanding and confronting the many challenges facing Asia in the decades ahead. “Fascinating… Although several books have been written about the strategic and geopolitical significance of the Indian Ocean…there is little awareness of the cultural and historical ties that bind diverse nations bordering the bay. Amrith’s signal achievement is to bring these ties to light. In doing so, he gives voice―and an identity―to one of the most complex and culturally interesting regions of the world… Amrith’s excavation of this culture is painstaking and meticulous. He digs deep into the archives, drawing on journals, letters and official colonial records to assemble an account that dates back to the first millennium… The result of all this research is a textured biography of a region… This is a formidable work of scholarship… It is the sheer accumulation of information, and the multiple, interwoven strands in this profoundly interdisciplinary work, that yield such an impressive, multifaceted portrait… [A] remarkable book.” ― Akash Kapur , New York Times Book Review “Sunil Amrith consolidates his reputation for intellectual sophistication, a good historian’s sensitivity to detail and a flair for large-scale tale-telling that produces work as page-turning as a novel. We are reminded that the Bay of Bengal, the world’s largest, long stood at the heart of global trade and imperial histories―the watery counterpart to the overland silk route that connected the Indian Ocean with Asia, Mediterranean societies and even South America via the flow of goods such as silver and pepper… Read this book for information, for convincing analytic nuance, as a humbling shake-up of one’s worldview, and as a series of heart-stopping tales.” ― Caroline Osella , Times Higher Education “Sunil Amrith’s astonishingly researched and lyrically written book evokes and showcases the toils, trials and fortunes of millions of Indians who have made the turbulent expanse of water from Trincomalee, Chennai and Vishakhapatnam to Calcutta, Chittagong, Rangoon, Penang, Malacca and Singapore their karm-bhoomi over the last several centuries. Crossing the Bay of Bengal is, in a very real sense, a life of that Bay itself, as it was buffeted and regulated by the monsoon winds during the long Age of Sail, then harnessed by steamships from the 1870s.” ― Shahid Amin , Indian Express “In refocusing on the Bay and restoring a Braudelian sweep to its history, this nicely written and meticulously researched study could prove as timely as it is instructive.” ― John Keay , Literary Review “The highlight of this…book is the way Amrith introduces the bay’s early trade routes and encourages further reading into its ancient civilizations―from the medieval Hindu-Buddhist Srivijaya empire of Sumatra, who ruled much of Southeast Asia, to the powerful Chola (southern India) dynasty’s thriving China trade. Such accounts reveal vibrant ‘East-meets-West’ business communities where Arab, Indian and, later, European ships moored alongside Chinese junks for cloth, spices, opium and Mexican silver. Amrith brings these images to life with clear maps and thoughtful research, such as the observations of Portuguese apothecary Tomé Pires, who noted 84 languages ‘from the Middle East to China’ in early 16th-century Melaka. Equally engaging is the way Amrith portrays traders’ study of the bay’s monsoons, and how they intermarried with locals from across the bay to create hybrid cultures and architecture that embraced multiple b
