The General Agreement on Tariffs and Trade (GATT) was negotiated in 1947 and was designed to reduce trade barriers and encourage free trade. It provided an international forum for negotiating tariff reductions and resolving trade disputes. While GATT was successful in significantly reducing tariffs over time, growing non-tariff barriers and subsidies in response to economic difficulties undermined its effectiveness. This led to negotiations in the 1980s and 1990s that transformed GATT into the World Trade Organization in 1995 to strengthen and expand the global trading system to address new challenges.
