First-wave feminists opposed abortion while second-wave feminists defended it.

Evidence

In the 1950s and 1960s, two opposing forces emerged around the issue. While many first-wave feminists declared their opposition to abortion, casting it as a consequence of male promiscuity and the degradation of women, feminists in the second wave saw the criminalization of abortion as an intrusion on women’s right to bodily autonomy and private decisionmaking regarding health and family. — Katherine Stewart, The Power Worshippers, 264
