Birth control movement in the United States [SEP] Introduction
The birth control movement in the United States was a social reform campaign beginning in 1914 that aimed to increase the availability of contraception in the U.S. through education and legalization. The movement began in 1914 when a group of political radicals in New York City, led by Emma Goldman, Mary Dennett, and Margaret Sanger, became concerned about the hardships that childbirth and self-induced abortions brought to low-income women. Since contraception was considered to be obscene at the time, the activists targeted the Comstock laws, which prohibited distribution of any "obscene, lewd, and/or lascivious" materials through the mail. Hoping to provoke a favorable legal decision, Sanger deliberately broke the law by distributing "The Woman Rebel", a newsletter containing a discussion of contraception.
