<human>:  What is the history of feminist movements in the US?
<bot>: The history of feminist movements in the US stretches back to the mid-nineteenth century when the first wave of feminism began. This movement fought for voting rights and the establishment of educational and employment opportunities for women. In the mid-twentieth century, the Second Wave of feminism emerged, pushing for the decriminalization of birth control, greater access to reproductive health care, and various other legal reforms to protect women’s rights. In the late 1960s, a Third Wave of feminism also emerged, focusing on issues of discrimination against women of color, LGBT+ rights, and women’s rights around the world. Today, the Fourth Wave of feminism is working to challenge the various systems of oppression that continue to affect women nationwide.
