Scholars from all over the world contributed to the Festschrift volumes presented as a tribute to Thomas Hodgkin on his sixtieth birthday. This book contains a selection from those contributions, reflecting the wide scope of Hodgkin's own interests, work and influence in the field of African and Tiers Monde studies. All the contributions represent original and previously unpublished work in the fields of African history, Islamic studies and the sociology of religion, and also of contemporary political and economic studies. They are particularly concerned to examine questions of a general and theoretical importance, often by means of detailed case studies. Among the countries thus discussed are Ghana, Guinea, Nigeria, Senegal, Guiné Bissao, Zambia, Ivory Coast, Tanzania, Gambia - and, as part of the African diaspora, Jamaica. Fittingly, these essays share one of the main features which have distinguished Thomas Hodgkin's own work - they take a critically evaluative view of some of the established interpretations and conventional wisdoms surrounding their subjects. This book will provide an introduction in depth to the whole field of African studies as well as being essential material for specialists in many disciplines.

A Companion to Australian Art is a thorough introduction to the art produced in Australia from the arrival of the First Fleet in 1788 to the early 21st century. Beginning with the colonial art made by Australia’s first European settlers, this volume presents a collection of clear and accessible essays by established art historians and emerging scholars alike. Engaging, clearly-written chapters provide fresh insights into the principal Australian art movements, considered from a variety of chronological, regional and thematic perspectives.The text seeks to provide a balanced account of historical events to help readers discover the art of Australia on their own terms and draw their own conclusions. The book begins by surveying the historiography of Australian art and exploring the history of art museums in Australia. The following chapters discuss art forms such as photography, sculpture, portraiture and landscape painting, examining the practice of art in the separate colonies before Federation, and in the Commonwealth from the early 20th century to the present day. This authoritative volume covers the last 250 years of art in Australia, including the Early Colonial, High Colonial and Federation periods as well as the successive Modernist styles of the 20th century, and considers how traditional Aboriginal art has adapted and changed over the last fifty years.The Companion to Australian Art is a valuable resource for both undergraduate and graduate students of the history of Australian artforms from colonization to postmodernism, and for general readers with an interest in the nation’s colonial art history.

First published in 1984. This book represents a major study of union responses to the economic crisis of the 1970s and 1980s. Abjuring governmental or managerial outlooks, it argues that unions, as representatives of essential producer groups, would be central to the renegotiation of the economic world. The work also stresses the importance of situating union responses to the crisis within the socio-historical evolution of their political economies during the rise and decline of the post-war economic boom. The Social Democratic affiliation of unions in Britain, West Germany and Sweden make them particularly comparable. This title will be of interest to students of politics and economics.

Leeds is the UK’s third largest city and is home to a community rich in history, ambition and achievement. As the financial, cultural and commercial heart of West Yorkshire, Leeds is a city essential to the global economic system. Although only a small borough for much of its existence, in the seventeenth and eighteenth centuries Leeds became a key centre for the production and trading of wool. As the Industrial Revolution progressed, Leeds developed into a major industrial hub, extending its reach into engineering, printing, commerce, health and education. Iron foundries were among other industries of extreme importance. The city then expanded, absorbing many of the surrounding villages and townships to become the urban centre we see today.Secret Leeds is a historical journey through this rapidly changing city, unearthing nuggets of its early history and spectacular development into the ‘Capital of the North’. The book reveals and unravels scores of fascinating and little-known details about Leeds that will intrigue and inform its many visitors as well as its current inhabitants, many of whom probably thought they knew it all.
