What is the name of the agreement that created the World Trade Organization?

The agreement that created the World Trade Organization is the Marrakesh Agreement. It was signed in Marrakesh, Morocco, on 15 April 1994, and the WTO came into existence on 1 January 1995.

The agreement concluded the Uruguay Round, the eighth major round of multilateral trade negotiations under GATT. Its package covered much more than tariff reductions: it established rules for services through GATS, intellectual property through TRIPS, agriculture, technical barriers and sanitary measures, and a more legally binding dispute-settlement system.

The Uruguay Round was the negotiation process, not the founding agreement itself. Likewise, the Doha Agreement is not the WTO’s constitutional treaty; the Doha Round began later, in 2001, as a new negotiating agenda within the WTO system.
