From the mid 1800s to the mid 1900s, the Comstock laws prevented the distribution of information regarding contraceptives in America. Therefore, few women had knowledge of available contraceptives, resulting in large families and high infant mortality rates, especially within the lower classes. Margaret Sanger first took a stand against the Comstock laws by publishing "Woman Rebel" and "Family Limitation," which helped start the birth control movement in America and connected Sanger with other activists. This connection helped Sanger continue her stand when she created the first birth control clinic in America. The clinic, though short lived, allowed the movement to gain support and national attention, giving Sanger a platform to start the first birth control conference in America, and later, develop the first contraceptive pill. These actions led to the widespread acceptance and use of birth control, allowing people to control their family size, contributing to the decline in infant mortality rates, and increasing women's education and employment opportunities.
