"Solidarity! Transnational Feminisms Then and Now" features 50 years of transnational feminist collections held at the Schlesinger Library on the History of Women in America. Through a rich array of materials—including posters, newspapers, photographs, and memorabilia—the exhibition explores the promises and limits of global feminist solidarity, while highlighting the key role of iconography in transnational feminist and women of color activism from the 1970s to the present. It reveals the complex, vexed history of international women’s rights, sisterhood, and alliance through the lens of the spectacular United Nations International Women’s conferences held in Mexico City in 1975, Copenhagen in 1980, Nairobi in 1985, and Beijing in 1995. These conferences shaped a new global agenda for women’s causes on the international stage. Women from around the world debated the possibilities of an international feminist alliance and reimagined civil rights for women through conference themes of equality, peace, and development.
