The American Board of Commissioners for Foreign Missions (ABCFM) was among the first American Christian missionary organizations. It was created in 1810 by recent graduates of Williams College. In the 19th century it was the largest and most important of American missionary organizations.
In 1961 the ABCFM or the American Board, as it was often called, merged with other societies to form the United Church Board for World Ministries, an agency of the United Church of Christ. Other organizations that draw inspiration from the ABCFM include InterVarsity Christian Fellowship, the Conservative Congregational Christian Conference, and the Missionary Society of the National Association of Congregational Christian Churches.
The ABCFM consisted of an annual meeting with a Prudential Committee (aka Executive Committee) that took care of day-to-day business. It elected a Corresponding Secretary to produce written documents, and a Treasurer to receive donations, and had Board Members.
The ABCFM held its first meeting on 5 September 1810, and elected Samuel Worcester corresponding secretary.
Note: After some secessions due to the slavery issue and the movement of New School Presbyterian-affiliated missionaries to the Presbyterian Board of Foreign Missions, the ABCFM was left as a Congregationalist body after 1870.
Note: After 1930, the ABCFM revised its constitution to create the position of "Executive Vice-President" to provide a position that was "first among equals" amongst ABCFM secretaries.
Note: when the Evangelical and Reformed Church merged with the Congregational Christian Church in 1957, the Congregationalist-affiliated ABCFM merged with the E&R affiliated Board of International Missions to become the United Church of Christ denomination's United Church Board of World Ministries under Dr. Carleton On June 29, 1961, the ABCFM formally concluded. On July 1, 2000, a UCC restructure renamed UCBWM became "Wider Church Ministries" under the UCC's covenanted ministries structure.
