Who knew?
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.
Making Abortion Illegal
In the mid-to-late 1800s states began passing laws that made abortion illegal. The motivations for anti-abortion laws varied from state to state. One of the reasons included fears that the population would be dominated by the children of newly arriving immigrants, whose birth rates were higher than those of "native" Anglo-Saxon women.
Medical Practice
During the 1800s, all surgical procedures, including abortion, were extremely risky. Hospitals were not common, antiseptics were unknown, and even the most respected doctors had only primitive medical educations. Without today's current technology, maternal and infant mortality rates during childbirth were extraordinarily high. The dangers from abortion were similar to the dangers from other surgeries that were not outlawed.
The Medical Establishment
The strongest force behind the drive to criminalize abortion was the attempt by doctors to establish for themselves exclusive rights to practice medicine. They wanted to prevent "untrained" practitioners, including midwives, apothecaries, and homeopaths, from competing with them for patients and for patient fees.
The best way to accomplish their goal was to eliminate one of the principle procedures that kept these competitors in business. Rather than openly admitting to such motivations, the newly formed American Medical Association (AMA) argued that abortion was both immoral and dangerous. By 1910 all but one state had criminalized abortion except where necessary, in a doctor's judgment, to save the woman's life. In this way, legal abortion was successfully transformed into a "physicians-only" practice.
