Thomas Campbell, Irish minister and theologian (d. 1854)
Thomas Campbell (1 February 1763 – 4 January 1854) was a Presbyterian minister who became prominent during the Second Great Awakening of the United States. Born in County Down, he began a religious reform movement on the American frontier. He was joined in the work by his son, Alexander. Their movement, known as the "Disciples of Christ", merged in 1832 with the similar movement led by Barton W. Stone to form what is now described as the American Restoration Movement (also known as the Stone-Campbell Restoration Movement).
