Do women national leaders represent a breakthrough for the women's movement, or is women's leadership weaker than the numbers imply? This unique book, written by an experienced politician and academic, is the first to provide a comprehensive overview of how and why women in 53 countries rose to the top in the years since World War II. Packed with fascinating case studies detailing the rise to power of all 73 female presidents and prime ministers from around the world, from 1960 (when the first was elected) to 2010, the motives, achievements and life stories of the female top leaders, including findings from interviews carried out by the author, provide a nuanced picture of women in power. The book will have wide international appeal to students, academics, government officials, women's rights activists and political activists, as well as anyone interested in international affairs, politics, social issues, gender and equality.
