The Supreme Court’s decision in 1973’s Roe v. Wade proved to be one of its most contentious in the modern era. Reflecting the influence of the sexual revolution and the women’s rights movement, Roe decriminalized abortion across the nation and protected the right to access abortion legally in all fifty states, most of which banned abortion except under specific circumstances. The Court based its decision largely on its interpretation of the Fourteenth Amendment, specifically its guarantee of individual privacy, which extended to the right to an abortion up to the point of fetal viability at roughly twenty-four weeks. But the decision offered no explicit protections for access to abortion, only the right to one, a limitation some states exploited by passing laws that made abortion extremely difficult to obtain.
