"Declaration on Procured Abortion" (1974), by the Vatican

As various societies around the world began legalizing abortive procedures or liberalizing government stances on abortion, the Roman Catholic Church's leaders felt the need to respond to these changes by clarifying the Church's position on procured abortion. One incident in particular that may have inspired the "Declaration on Procured Abortion" is the landmark case in the United States Supreme Court in 1973: Roe v. Wade. This case, which legalized a wide range of abortion procedures in perhaps the most influential nation in the world, spurred conversation regarding the morality of procured abortion throughout the world. The Vatican's response was initiated by the Sacred Congregation for the Doctrine of the Faith which, under the guidance of the Prefect Franciscus Seper and Archbishop Hieronymus Hamer, became the "Declaration on Procured Abortion."
