College of Indiana joined with Purdue University's medical school in 1905 (itself later merging with the Indiana University School of Medicine in 1908).
In 1930, Butler merged with the Teachers College of Indianapolis, founded by Eliza Cooper Blaker, creating the university's second college. The third college, the College of Business Administration, was established in 1937, and the College of Pharmacy and Health Sciences was established in 1945, following a merger that absorbed the Indianapolis College of Pharmacy. The Jordan College of Fine Arts, the university's fifth college, was established in 1951, following a merger with the Arthur Jordan Conservatory of Music.
The university's department of religion became a separate Christian Church seminary and "college of applied Christianity" in 1924; it was variously called the School of Religion and the College of Religion. The school became independent in 1958 and is currently known as the Christian Theological Seminary.
