American Baptist Churches USA

The American Baptist Churches USA, abbreviated as ABCUSA, is a mainline Protestant and Baptist Christian denomination in the United States. The American Baptist Churches is the reorganization from 1907 of the Triennial Convention, established in 1814. It is rooted in the early English and Welsh Baptist settlers in America, especially with the foundation of Rhode Island Colony, tracing its history to the First Baptist Church in America, established by Roger Williams in 1638. The Triennial Convention became the Northern Baptist Convention in 1907, which was renamed as the American Baptist Convention from 1950 to 1972.
