What can war tell us about empire? In Climate of Conquest, Pratyay Nath seeks to answer this question by focusing on the Mughals. He goes beyond the traditional way of studying war in terms of battles and technologies. Instead, he unravels the deep connections that the processes of war-making shared with the society, culture, environment, and politics of early modern South Asia. Climate of Conquest closely studies the dynamics of the military campaigns that helped the Mughals conquer North India and project their power beyond it. The author argues that the diverse natural environment of South Asia deeply shaped Mughal military techniques and the course of imperial expansion. He also sheds light on the world of military logistics, labour, animals, and the organization of war; the process of the formation of imperial frontiers; and the empire’s legitimization of war and conquest. What emerges is a fresh interpretation of Mughal empire-building as a highly adaptive, flexible, and accommodative process.
