Worldwide concerns can no longer be addressed effectively without acknowledging the centrality of half of humanity to solving them. The global Women’s Movement’s growth persists because of women’s desperate need and determination, but with limited resources, often inadequate infrastructure, and support too small to permit the institutional development that is essential to invest maningfully in women.

The Sisterhood Is Global Institute (SIGI), an international nonprofit NGO with consultative status to the United Nations, has for almost three decades functioned as the world’s first feminist think-tank. SIGI has also developed a global communications network through which an umbrella of NGO interest, advice, contacts, and support can collectively be mobilized for greater, more cost-effective impact in connecting and empowering the global women’s movement.

Founded in 1984 by Robin Morgan (US), the late Simone de Beauvoir (France), and women from 80 other countries, the Institute has played a leading policy-formulation, strategic, and activist role in the evolution of the international Women’s Movement for nearly 30 years.

The Institute spun off from the book Sisterhood Is Global: The International Women’s Movement Anthology, compiled and edited by Morgan. At publication, Morgan organized the first ever global feminist strategy meeting. During that assembly, de Beauvoir (France) and Morgan (US), together with women from Barbados, Brazil, Chile, Colombia, Cuba, Finland, Fiji, Greece, Italy, India, Kuwait, Libya, Mexico, Nepal, New Zealand, Nigeria, Norway, Palestine/Israel, Poland, Saudi Arabia, Spain, Sri Lanka, Thailand, and Zambia, founded the Institute as the first international feminist
think-tank “pledged to visionary yet pragmatic action in support of women’s rights, freedoms, and power.”

Among its many activities, the Institute pioneered the first Urgent Acton Alerts regarding women’s rights; the first Global Campaign To Make Visible Women’s Unpaid Labor In National Accounts; and the first Women’s Rights Manuals For Muslim Societies (in 12 languages) .
Original plans called for the institute to rotate location every five
years. Accordingly, the institute spent its first five years in New York under the executive directorship of Karen Berry; the next five in New Zealand, led by former Nz Member of Parliament Marilyn J. Waring; it then moved to Maryland, USA, under Mahnaz Afkhami (Iran); thence to Montreal, Canada, with Greta Hofmann Nemiroff at the helm, and more recently back to New York under the Executive Directorship of Tamera Gugelmeyer.

Today, permanently located in New York City, SIGI is guided by its President and a distinguished Board of International Advisors.
