Central to the history of family planning in Ireland is the interaction between religious observance and expressions of Irishness, and how that changed in response to domestic political and socio-economic developments, and international forces. An Irish identity imagined around rural living, Catholicism, large families, traditional gender roles, and sexual puritanism, combined with a belief that Ireland could withstand the changes that were underway in twentieth-century western society in relation to sexual behaviour – drove the sustained hostility to legalising contraception. The 1980s was the decade when it became evident that the tide had turned. The number of married women in the workforce rose significantly, and fertility fell sharply. By the early 1990s Irish fertility was still the highest in Europe, but only by a small margin, and it was lower than in the United States. And yet the decline of this imagined Irishness was not unopposed; indeed, many lamented its passing. it is significant that the moral legislation enacted in the first decades after independence survived until the closing decades of the twentieth century, which might suggest that Ireland was exceptional.

No western country experienced as protracted a debate on contraception as Ireland. The longstanding ban on contraception has commonly been seen as the consequence of Catholic church teaching and the near-universal religious observance by Irish Catholics. But the Irish debate went far beyond Catholic teaching. The merits of large families and the laws banning contraception (as well as prohibition of divorce and abortion) came to be seen as a symbol of Ireland’s national identity; the Irish approach to contraception was intimately bound up with ideas of Irishness. The logic of opposition to the use of contraception shifted over the decades. Initially, the belief that ‘artificial’ contraception was contrary to the teaching of the Catholic church was the engine that drove state policy and broader opposition. By the 1970s this argument was being abandoned, in favour of claims that permitting contraception would destroy the fabric of the family and society. The battle to protect Irish society from the “menace” of contraception, abortion and divorce continued into the present century in the face of falling fertility, many single mothers, and a significant abortion trail to Britain.
