At first sight, the last fifteen years has been the most creative—as certainly it has been the most productive—period in the history of the study of why the Mughal empire in India declined. The succession of magisterial publications from the Department of History at the University of Aligarh—Satish Chandra's Parties and Politics at the Mughal Court 1707–1740 (1959), Irfan Habib's The Agrarian System of the Mughal.Empire (1556–1707) (1963), M. Athar Ali's The Mughal Nobility under Aurangzeb (1966), and Noman Ahmad Siddiqi's Land Revenue Administration under the Mughals (1700–1730) (1970)—have, taken together, offered formulae for the understanding of the growing weakness of the empire from the later seventeenth century almost Newtonian in their force and simplicity.
