The Diocese of the West was founded in 1998 as part of the Anglican Province of America (APA), a Continuing Anglican church in the Anglo-Catholic tradition. In 2008, its bishop, Richard Boyce, arranged for the diocese to affiliate with the Reformed Episcopal Church. To that point, the APA and REC had been in full communion, but Boyce sought for the Diocese of the West to have full participation in the Common Cause Partnership that led to the creation of the Anglican Church in North America in 2009. The Diocese of the West was the only diocese of the Continuing Anglican Movement to join the ACNA. In 2011, Winfield Mott, the coadjutor bishop of the West, became diocesan bishop upon Boyce's retirement. In April 2016, the diocese transitioned to a convocation in the Missionary Diocese of All Saints, at which point Bishop Mott became Vicar General of the Convocation of the West.
