Irish Women and the Creation of Modern Catholicism is the only book-length study of lay Catholic women in modern Irish history. Focusing on the pivotal century from 1850 to 1950, it analyses the roles that middle-class, working-class, and rural poor lay women played in the evolution of Irish Catholicism and thus the creation of modern Irish identities. This project demonstrates that in an age of Church growth and renewal stretching from the aftermath of the Great Famine through the early years of the Irish Republic, lay women were essential to all aspects of Catholic devotional life, including both home-based religion and public Catholic rituals. It also reveals that women, by rejecting, negotiating, and reworking Church dictates, complicated Church and clerical authority. Irish Women and the Creation of Modern Catholicism re-evaluates the relationship between the institutional Church, the clergy, and women, positioning lay Catholic women as central actors in the making of modern Ireland. It also contests views that the increasing power of the Catholic Church caused a uniform decline in Irish women’s status after the Great Famine of the 1840s, revealing that middle-class, working-class, and rural poor lay women fought with their priests, dominated household religion, and led parish rituals, thus proving integral to the development of a modern Irish Catholic ethos and culture.
