Eisenstadt v. Baird was a landmark Supreme Court case decided in 1972 that established the right to privacy in the context of reproductive rights, particularly concerning access to contraception. This case reinforced the notion that individuals have a fundamental right to make decisions about their own reproductive health without unwarranted government interference. The ruling also played a critical role in advancing personal liberties, especially for unmarried individuals, highlighting the significance of both substantive due process and the broader women's rights movement.
