By the 1930s Stewart became a leading member of community groups in Toledo, including the Young Women's Christian Association (YWCA) and the Enterprise Charity Club, a social-service organization run by African-American women. As leader of the NACWC, Stewart spoke out against segregation, discrimination, and racist stereotypes. In 1961 she became an inaugural member of the Toledo Board of Community Relations, which worked to improve race relations in the city, and to ensure enforcement of civil-rights legislation. Stewart's civic activities eventually took on an international dimension: in 1952 she was appointed as an American delegate to the International Conference of Women of the World, held in Athens, Greece. She subsequently spent time during the 1950s touring as a goodwill ambassador for the United States; in 1954 one such U.S. State Department tour took her to several nations in Southeast Asia, including India, Indonesia, Pakistan, and Sri Lanka. In 1963 she was appointed to the United States commission of the
United Nations Educational, Scientific and Cultural Organization (UNESCO), and in her role, she travelled around the world as a US goodwill ambassador. Stewart spent the rest of her life in
Toledo, remaining active as a volunteer and philanthropist. ==Personal==
