The history of birth control and abortion is a long one. In the United States, abortion and contraception were legal from Colonial times until the late 1800s. Then state legislatures, pushed by the American Medical Association, began outlawing abortion. And some states adopted and expanded Comstock laws, set by the federal postal service to ban the shipping of contraceptives and informational pamphlets.
At about the same time these laws were passed, the concept of the right to privacy began to emerge.
