Lancaster Theological Seminary, a seminary of the United Church of Christ in Lancaster, Pennsylvania, was founded in 1825 by members of the German Reformed Church in the United States to provide theological education for prospective clergy and other church leaders. After a failed attempt to open the school in Frederick, MD and another in Harrisburg, PA, the school opened in Carlisle, Pennsylvania on the campus of Dickinson College on March 11, 1825 with a class of five students.
