Christian conservative Phyllis Schlafly died on Monday in St. Louis. She was 92.

Schlafly founded the Eagle Forum in 1975.

“Phyllis Schlafly spent an astounding 70 years in public service of her fellow Americans,” the group said in a statement. “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. 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.”

Schlafly, a self-described housewife, was known for her staunch opposition to feminism and successful campaign against ratification of the Equal Rights Amendment, which sought to guarantee equal rights for women. She also authored nearly two dozen books and wrote a syndicated weekly column.

A vocal opponent of LGBT rights, Schlafly claimed last May that the goal of equal marriage rights for gay and lesbian couples was “to wipe out the Christian religion.” The Supreme Court ruled in favor of marriage equality the following month in Obergefell.
