In 1844 the faculty "decided they had had enough of him" and attempted to have him removed, but "influential colleagues", including Finney, prevented it. Another attempt in 1847 also failed. In 1850, this time with Finney's support, the faculty prepared a "searing ten-count indictment" of his "overbearing behavior". He resigned. In his place, famed abolitionist and preacher Charles Finney (already an Oberlin professor) was made president of Oberlin College. Heartbroken, Mahan moved to Cleveland, Ohio, and participated in the founding of Cleveland University, located in the Tremont District of the city, where he was chosen president of the school and also professor of mental and moral philosophy. However, the school had trouble attracting students and went bankrupt after only a few years, and Mahan was forced out.
