Rice worked to unite Baptists in America to support foreign missionaries which resulted in the organization of "The General Missionary Convention of the Baptist Denomination in United States of America, for Foreign Missions," also called the
Triennial Convention, in 1814. Also in 1814, Rice was awarded an honorary doctorate by then Baptist-dominated
Brown University in partial recognition for his contributions to missionary work undertaken through his Baptist denomination. He spent the rest of his life garnering support for missionaries and Baptist work, traveling across America by horseback to raise funds and awareness for Baptist missions. Rice also founded
Columbian College in 1821, the original unit of present-day
George Washington University, in
Washington, D.C. He served as the treasurer of Columbian College from 1826 until his death, September 25, 1836, in
Saluda, South Carolina, while traveling through the
Southern United States raising funds for the missions and seminaries that he founded. Although his life was not without controversy, Rice's contribution to the support of missionary work was invaluable in the early years of the Triennial Convention. During Rice's lifetime, the Triennial Convention's membership grew from 8,000 to 600,000, and the convention supported 25 missions and 112 missionaries. By the time of his death, 15 Baptist universities and colleges had been formed.
Luther Rice College & Seminary founded in 1962 and located in
Lithonia, Georgia, USA, was named after Luther Rice in recognition of his work in the Baptist missions and seminary education. ==Genealogy==
