Phyllis Schlafly, the political activist who rose to fame in the 1970s when she campaigned against the Equal Rights Amendment, has died at the age 92, according to the Los Angeles Times.
The woman known as "the first lady of anti-feminism" died of natural causes in her St. Louis home Monday, according to the Eagle Forum, a Missouri-based advocacy organization she led.
Her daughter, Anne Cori, told the Washington Post Schlafly, had been battling cancer for some time.
In the 1970s Schlafly gained national prominence by leading "traditional-religious women" in a movement against the Equal Rights Amendment, according to Fox News.
Schlafly argued that the Equal Rights Amendment, which guaranteed equal rights under the law regardless of gender, would end the traditional family.
Her battle over the Equal Rights Amendment also helped launch the anti-abortion movement in the United States, according to the Washington Post.
"Her focus from her earliest days until her final ones was protecting the family, which she understood as the building block of life. She recognized America as the greatest political embodiment of those values," the Eagle Forum said in a statement.
"From military superiority and defense to immigration and trade; from unborn life to the nuclear family and parenthood, Phyllis Schlafly was a courageous and articulate voice for common sense and traditional values."
She most recently came out in support of Republican presidential nominee Donald Trump.
According to Fox News, Schlafly is survived by six children, 16 grandchildren and 3 great-grandchildren.
