She held conservative social and political views, opposed feminism and abortion, and successfully campaigned against ratification of the Equal Rights Amendment to the U.S. Constitution. Her book, A Choice Not an Echo (1964), a polemic against Republican leader Nelson Rockefeller, sold more than three million copies. Schlafly co-authored books on national defense and was critical of arms control agreements with the Soviet Union.[2] In 1972, Schlafly founded the Eagle Forum, a conservative political interest group, and remained its chair and CEO until her death in 2016 while staying active in conservative causes.
