The essays underline the determinants of electoral behaviour by looking into the correlation between the background variables of voters and their voting choices. The essays also compare and contrast the 2019 election verdicts from the earlier elections held in the state under study. A long view of Indian state politics, this book will be essential reference for scholars and researchers of politics, especially political processes, and South Asian studies.

This book explores the lives and social histories of Indians soldiers who fought in the First World War. It focuses on their motivations, experiences, and lives after returning from service in Europe, Mesopotamia, East Africa, and Palestine, to present a more complete picture of Indian participation in the war. The book looks at the Indian support to the war for political concessions from the British government and its repercussions through the perspective of the role played by more than one million Indian soldiers and labourers. It examines the social and cultural aspects of the experience of fighting on foreign soil in a deadly battle and their contributions which remain largely unrecognised. From micro-histories of fighting soldiers, aspects of recruitment and deployment, to macro-histories connecting different aspects of the War, the volume explores a variety of themes including: the material incentives, coercion and training which converted peasants into combatants; encounters of travelling Indian soldiers with other societies; and the contributions of returned soldiers in Indian society. The book will be useful to researchers and students of history, post-colonial studies, sociology, literature, and cultural studies as well as for those interested in military history, World War I, and colonial history.

From the 1600s, enslaved people, and after abolition of slavery, indentured labourers were transported to work on plantations in distant European colonies. Inhuman conditions and new pathogens often resulted in disease and death. Central to this book is the encounter between introduced and local understanding of disease and the therapeutic responses in the Caribbean, Indian and Pacific contexts. European response to diseases, focussed on protecting the white minority. Enslaved labourers from Africa and indentured labourers from India, China and Java provided interpretations and answers to health challenges based on their own cultures and medicinal understanding of the plants they had brought with them or which they found in the natural habitat of their new homes. Colonizers, enslaved and indentured labourers learned from each other and from the indigenous peoples who were marginalized by the expansion of plantations. This volume explores the medical, cultural and personal implications of these encounters, with the broad concept of medical pluralism linking the diversity of regional and cultural focus offered in each chapter.

Focusing on the twin issues of identity and development that are often signifiers of the unravelling politics in the federal polity, the book make a concerted attempt to look at (and beyond) the states by exploring the specificities of the regions within these states. It does so through a comparative study from the vantage point of democratic politics as it unfurls in recent India. Emphasising that regions within the states are not merely politico-administrative instituted constructs but are also imagined or constituted, among others, in historical, geographic, economic, sociological or cultural terms, it argues that any meaningful comparative study of the regions would naturally straddle the disciplinary boundaries of social sciences. The book attempts to go beyond the states and look at the regions within them as a distinctive analytical category for an in-depth study of the democratic politics of identity and development unfolding at the state level.

Microbial Stress Survival is an insightful resource for those interested in pathogen biology and the different adaptive features and resilience of microbes.Discusses the adaptive mechanisms of microbes that allow them to cross the defensive barrier of their hostCovers the proteins responsible for growth regulation of bacteria during unfavorable conditionsExamines microbial stress response and adaption to extreme environmentsExplores different bioremediation strategies for the degradation of various types of pollutants

Many Indians journeyed out of India to supplant the loss of slave labour in the former European plantation colonies of Mauritius, South Africa, Fiji, and the Caribbean from the early nineteenth century onwards. This book aims to highlight the careers of these migrants who served as vital agents in building the global society of the twenty-first century. It explores the transformative experiences of those who migrated, and the memories of those who did not return after expiration of their contracts but chose instead to stay in their respective host countries. It describes the many challenges they faced - ageing in a society far from home, the loss of their formal Indian identity after Indian independence, their efforts to preserve a sense of community in the post-independence societies of South Africa and the Caribbean, and their adapting to the new political and social realities they faced as minorities in the countries in which their ancestors had adventurously determined to settle and live.

This volume examines Indian states as analytical units, culminating in a comprehensive sociopolitical study of the country as a whole. The state-specific essays underline the federal context in which politics in India unfolds at the ground level.Employing a federalist and centrist analytical prism, this book aims to add to the existing body of work on state politics, with a particular focus on India in the last decade, which has shown visible shifts in political terms. It delineates the narratives and trends in politics at the state level and explores the range of issues and actors involved in it. It shows the myriad complex, overlapping and multidimensional ways in which politics unfold at the state level and goes on to make a national impact.The volume will be indispensable to scholars and researchers of South Asian politics, federalism, and contemporary India.

This book offers innovative insights from across disciplines to explore the soulful survival of migrants, refugees, and displaced individuals and communities amidst stalemates, crises and compromises in human rights. Dwelling on ethnographic case studies from Asia, Africa, Latin America, the United States, and Europe, the volume illuminates the experiences of vulnerable communities, showcasing their solidarities, networks, and supportive dynamics that emerge from the harsh realities of social life. Analysing the world from the lens of fraternal relations and spaces that arise and abound in the lifeworld of the marginalised and vulnerable communities, this edited volume illustrates how without these burgeoning solidarities, migrants and other at-risk populations may have a harder struggle to navigate the socio-economic and political challenges they face. Furthermore, the book emphasises that nation-states would encounter even more profound and complex difficulties without such intricate coping mechanisms. The chapters within the volume demonstrate that these mechanisms are vital to addressing dilemmas, stalemates, and the stakeholder politics surrounding people living in precarious, hidden and dark contexts. The case studies which enrich theoretical debates also indicate how these dark contexts would be significantly more difficult to traverse without the robust and nuanced messages coded in actor solidarities and resilience.The volume is poised to attract significant attention from scholars and researchers committed to anthropology, ethnography, history, migration, international politics and refugee studies.

This book studies Indian overseas labour migration in the nineteenth and early twentieth centuries, which involved millions of Indians traversing the globe in the age of empire, subsequent to the abolition of slavery in 1833. This migration led to the presence of Indians and their culture being felt all over the world. This study delves deep into the lives of these indentured workers from India who called themselves girmitiyas; it is a narrative of their experiences in India and in the sugar colonies abroad. It foregrounds the alternative world view of the girmitiyas, and their socio-cultural and religious life in the colonies. In this book, the author has developed highly original insights into the experience of colonial indentured migrant labour, describing the ways in which migrants managed to survive and even flourish within the interstices of the indentured labour system and how considerably the experience of migration changed over time.

In recent decades, India has been witness to the assertion of geographically, culturally and historically constituted distinct and well-defined regions that display ethnic, communal, caste and other social–political cleavages.This book examines the changing configurations of state politics in India. Focussing on identity politics and development, it explores the specificities of the regions within states — not merely as politico-administrative constructs but also as conceived in historical, geographic, economic, sociological or cultural terms. Adopting a comparative approach, the book looks at alternative theoretical approaches — the quest for homeland, identity, caste politics and public policy.This second edition includes a new Introduction that updates the research in the area, while further developing the theoretical framework.One of the first major volumes on federalism in India, including studies from across the nation, this book will be indispensable for students and scholars of political science, sociology, history and South Asian studies.
