Transformations of African Marriage [PDF ebook] 

Originally published in 1987, this book shows that there is still considerable continuity in the practices and ideas of marriage in Afican against a background of social and economic change. This book discusses the diverse marriage forms in Africa and explores the different systems some of which can be understood in terms of Levi-Strauss’s distinciton between complex and semi-complex structures, while others throw up questions of filiation, child custoidanship and rights secured through bridewealth transactions.
