Mount Lebanon was probably the first permanent settlement in what is now Bienville Parish. Its pioneers were Baptists from South Carolina who quickly established a church and school. The school became Mount Lebanon University in 1853, but closed during the Civil War to serve as a high school and a Confederate hospital. After the war the school reopened. After years of struggling, it was consolidated in 1906 through the Louisiana Baptist Convention into Louisiana College in Pineville in Rapides Parish in central Louisiana.
