General Agreement on Tariffs and Trade
From 1947 until 1959 (the Torquay round), existing tariffs were frozen with respect to listed commodities. From 1959 to 1979, the parties to GATT reduced tariffs. From 1986 to 1994 (the Uruguay round), the parties expanded the agreement to include agriculture, intellectual property, capital and services.
In 1995 the WTO replaced GATT.
