‘Focusing on the relationship between Asia and Europe, this is an important and fascinating account of the development of military practice and systems. The concept of convergence and divergence serves Professor Roy well in a study that deserves widespread attention.’--Jeremy Black, University of Exeter, UK

‘This outstanding work is a hugely ambitious and scholarly analysis of the diversity of the human experience of war over millennia. Kaushik Roy eschews simplifications and slogans to come to grips with one of the most important – and most horrible – aspects of human behaviour and reveals patterns of change and development across the millennia of human existence.’--John France, Swansea University, UK

‘Military historiography has long favored the narrative of Western exceptionalism, rising out of Greece and Rome, and carried forward by knights against Islamdom until European gunpowder armies and navies conquered the world as part of the supposed "Military Revolution." Kaushik Roy's present book is a tour de force in its reassessment of Eurasian military history and its demonstration that many of the elements of war in different periods attributed to a Western lineage beginning with the Romans and the Greeks were actually born in and shared across Eurasia, that there were in fact many military revolutions across Eurasia that marked the rise of Asian military prowess, and that will into the eighteenth century, European armies could still have been outmatched by the Mongol armies of the thirteenth century. This book with its more complex distillation of the findings of the growing literature on nonwestern military developments, its timely relocation of historical military developments to multiple Eurasian nodes, and its erudite analysis of the factors that kept Asian armies competitive with those of Europe is a significant contribution to our understanding of the world of warfare prior to 1500.’--Michael W. Charney, SOAS, University of London, UK

‘This sweeping new survey persuasively challenges many of the hoary axioms that have long dominated Western historians’ views on premodern warfare. Kaushik Roy takes aim at earlier analyses that turned on over-simplified notions of "Eastern" and "Western" Ways of War, and the dominance of technological change. In their place, he offers a more textured model of recurring convergence, divergence and amalgamation in the organization of military forces and the conduct of war within and among the diverse civilizations of premodern Eurasia, driven by a matrix of cultural, political, geographic, and technological factors. This is an essential read for all students of world military history.’--Karl Friday, University of Georgia, USA
