Unmarried women had legal access to birth control many years before they had access to abortion services.
The Comstock Act, passed by Congress in 1873, prohibited birth control advertisements, information and distribution and allowed the U.S. Postal Service to confiscate birth control sold through the mail. Many people, most notably Margaret Sanger, fought the Comstock Act and went to jail repeatedly for attempting to provide birth control education and supplies to women and couples. The federal ban on birth control was lifted in 1938, in a case involving Sanger. However, it was not until 1965 that the Supreme Court, in the case Griswold v Connecticut, established the Constitutional right of married couples to use birth control, on the basis of a “right to privacy.” And it was not until 1972 that the Supreme Court struck down a Connecticut law that banned the use of birth control by unmarried couples and established, in Eisenstadt v Baird, the right of unmarried couples to obtain contraceptives. Only one year later, the Supreme Court ruled that women had a constitutional right to abortion in Roe v Wade.
Abortion was illegal in the United States up until the Roe v Wade decision.
Actually, at the founding of our nation, abortion was generally permitted in most states under common law. It began to be criminalized in the mid-1880s and by 1890 almost every state had enacted a law declaring most abortions to be criminal offenses. These laws against abortion were largely driven by doctors citing concerns about the safety of abortions performed by midwives or other untrained, but traditional providers.
