A World Conference on Faith and Order was first proposed by the Episcopal Church in 1910 to build ecumenical consensus and Christian unity. The conference took years to plan and was delayed by World War I as well as the inherent organizational challenges of such an event. Finally, 394 delegates representing 108 churches attended the First World Conference on Faith and Order in Lausanne from August 3–21, 1927. The event launched the ecumenical Faith and Order Movement, advocated by the Faith and Order Commission of the World Council of Churches. Further conferences have since been held all around the world.
