Tracing the Indian state's engagement with aviation, both civil and military, from the Second World War to the nationalization of airlines in 1953, this book argues that aviation played a critical role in state formation in modern South Asia.

The catalyst for this book is the fact that noted sociologist Charles Tilly, upon his death in 2008, left one completed chapter of an unfinished manuscript entitled “Cities, States, and Trust Networks,” examining the relationships between cities and nation-states over the sweep of history, and in particular the role of trust networks in mediating this relationship. Though this was the catalyst, the book serves a broader purpose: to survey recent frontier work on cities, nation-states, and the relations between the two in historical and contemporary perspective. Essays in the book will address four main themes: city-state relations, trust networks and commitment, democracy and inequality, and the importance of historical legacies in shaping state structures, practices, and capacities. They will be global in scope, with research on the United States, Latin America, Europe, Asia, and Africa; a number of the pieces will be comparative. They will also be interdisciplinary, including works of geography, history, political science, sociology, urban planning. The book addresses several confluent needs of readers. One is to simply update themes addressed in earlier edited work such as Bringing the State Back In (1985). A second is to bring together current thinking about cities on the one hand and nation-states on the other, literatures that are often segregated from each other. A third is to perform those two purposes in a way that is global in scope and combines both historical and current analyses, to pull together insights from the full range of human experience.

A few years ago, in the Wren Library of Trinity College, Cambridge, I came across a remarkable but then little-known album of pencil and watercolour portraits. The artist of most (perhaps all) was Thomas Charles Wageman. Created during 1829–1852, these portraits are of pupils of the famous mat- matical tutor William Hopkins. Though I knew much about several of the subjects, the names of others were then unknown to me. I was prompted to discover more about them all, and gradually this interest evolved into the present book. The project has expanded naturally to describe the Cambridge educational milieu of the time, the work of William Hopkins, and the later achievements of his pupils and their contemporaries. As I have taught applied mathematics in a British university for forty years, during a time of rapid change, the struggles to implement and to resist reform in mid-nineteenth-century Cambridge struck a chord of recognition. So, too, did debates about academic standards of honours degrees. And my own experiences, as a graduate of a Scottish university who proceeded to C- bridge for postgraduate work, gave me a particular interest in those Scots and Irish students who did much the same more than a hundred years earlier. As a mathematician, I sometimes felt frustrated at having to suppress virtually all of the ? ne mathematics associated with this period: but to have included such technical material would have made this a very different book.
