This button was produced by the Canadian government to mark 1975 as International Women’s Year, so designated by the United Nations. The UN began marking March 8th as International Women’s Day the same year. It also designated the decade from 1975-1985 as the Decade for Women. A world conference held in 1975 in Mexico established a set of goals to advance women’s rights over these ten years. In 1985, the World Conference to Review and Appraise the Achievements of the UN Decade for Women convened in Nairobi.
