Between 1972 and 1974, the Mighty Macs of Immaculata College - a small Catholic women's school outside Philadelphia - made history by winning the first three women's national college basketball championships ever played. In 1972, this unlikely 15th-seeded team, representing the smallest school in the tournament and the only Catholic institution, triumphed against enormous odds and four powerhouse state teams to secure the championship title and capture the imaginations of fans and sportswriters across the country. In doing so, they helped to legitimize women's sports in America. In the early 1970s, few women participated in organized athletics, but in Catholic Philadelphia women's basketball was already a well-established, thirty-year tradition, sponsored by the Philadelphia Archdiocese far in advance of public schools. In this vivid account of Immaculata basketball, Julia Byrne explores the unusual lives of these young women, the rare opportunities and pleasures they were allowed, the religious culture in which they lived, and the broader ideas of womanhood they inspired and helped redefine.
