The OXFORD HANDBOOK OF TRANSNATIONAL FEMINIST MOVEMENTS explores the historical, political, economic and social contexts in which transnational feminist movements have emerged and spread, and the contributions they have made to global knowledge, power and social change over the past half century. The publication of the handbook in 2015 marks the fortieth anniversary of the United Nations International Women's Year, the thirtieth anniversary of the Third World Conference on Women held in Nairobi, the twentieth anniversary of the Beijing Declaration and Platform for Action, and the fifteenth anniversaries of the Millennium Development Goals and of UN Security Council Resolution 1325 on 'women, peace and security'. The editors and contributors critically interrogate transnational feminist movements from a broad spectrum of locations in the global South and North: feminist organizations and networks at all levels (local, national, regional, global and 'glocal'); wider civil society organizations and networks; governmental and multilateral agencies; and academic and research institutions, among others. The handbook reflects candidly on what we have learned about transnational feminist movements. What are the different spaces from which transnational feminisms have operated and in what ways? How have they contributed to our understanding of the myriad formal and informal ways in which gendered power relations define and inform everyday life? To what extent have they destabilized or transformed the global hegemonic systems that constitute patriarchy? From a position of fifty years of knowledge production, activism, working with institutions, and critical reflection, the handbook recognizes that transnational feminist movements form a key epistemic community that can inspire and provide leadership in shaping political spaces and institutions at all levels, and transforming international political economy, development and peace processes. The handbook is organized into ten sections, each beginning with an introduction by the editors. The sections explore the main themes that have emerged from transnational feminist movements: knowledge, theory and praxis; organizing for change; body politics, health and well-being; human rights and human security; economic and social justice; citizenship and statebuilding; militarism and religious fundamentalisms; peace movements, UNSCR 1325 and postconflict rebuilding; feminist political ecology; and digital-age transformations and future trajectories.
