From Men and Abortion:
Abortion Was Legal
Abortion has been performed for thousands of years, and in every society that has been studied. It was legal in the United States from the time the earliest settlers arrived. At the time the Constitution was adopted, abortions before "quickening" were openly advertised and commonly performed.
The prohibition of legal abortion from the 1880s until 1973 came under the same anti-obscenity or Comstock laws that prohibited the dissemination of birth control information and services.
Criminalization of abortion did not reduce the numbers of women who sought abortions. In the years before Roe v. Wade, the estimates of illegal abortions ranged as high as 1.2 million per year.1 Although accurate records could not be kept, it is known that between the 1880s and 1973, many thousands of women were harmed as a result of illegal abortion.
