The movement for the higher education of women in Ireland in the nineteenth century has traditionally been viewed as a Protestant initiative. Scholarship suggests that the Irish campaign developed along the same lines as the English movement, gaining from and growing out of the English advances. Leading Protestant schools for girls have been viewed as the driving force behind the concessions afforded Irish women. This paper challenges this assumption, suggesting that contemporaneous developments in Ireland were driven not by neighbouring reforms but by denominational tensions. The role played by the Catholic teaching orders during the nineteenth century cannot be overlooked. Although initially conservative in their approach to educational provision for girls, the Catholic teaching orders--the Dominican, Loreto and Ursuline orders in particular--were key players and stakeholders in women's higher education in the latter half of the nineteenth century. This paper explores the objectives of the pioneers of Protestant and Catholic female education, examining the relative influence of the Church of Ireland and the Catholic Church. It explores the possibility that the movement for the higher education of Irish women found its impetus not in gender equality, but in denominational rivalry. (Contains 156 footnotes.)
