The World Assemblies of God Fellowship (WAGF), commonly known as the Assemblies of God (AG), is a global cooperative body or communion of over 170 Pentecostal denominations that was established on August 15, 1989. It was founded on the initiative of the Assemblies of God USA, the largest Pentecostal group in the United States. The WAGF was created to provide structure so that member denominations, which previously related to each other informally, could more easily cooperate on a global basis.
