This thoroughly researched, well-documented book presents a theoretically guided empirical analysis of developing and implementing gender equality policies in the European Union (EU). In spite of a wealth of research, many questions have long remained unanswered and these are addressed here. The author developed an international relations theoretical framework in order to explain the changing fortunes of women’s activism, the changing attitudes of European institutions and the behaviour of member states in a multi-level setting. The book traces the history and development of EU gender policy to the present day and will be inspirational reading for those interested in European governance and the European Union, as well as gender issues and political sociology.
