This chapter details the history, politics, and recent trends and challenges of the multilateral trade system. The twentieth century witnessed a remarkable emergence of international institutions, and nowhere was their impact greater than in international trade. Following decades of depression and war, a global trading regime was initiated with the creation of the General Agreement on Tariffs and Trade (GATT) in 1947, which expanded steadily in both scope and membership through the twentieth century and culminated in the establishment of the World Trade Organization (WTO) in 1995. Underpinned by the philosophy that open markets and non-discriminatory trade policies promote the prosperity of all countries, and issued with a powerful dispute settlement mechanism, the WTO has been hailed as the most prominent example of cooperation between countries. At the same time, however, the WTO has been subject to internal and external criticism and now faces a number of difficulties.
