The University of Ottawa was first established as the College of Bytown in 1848 by the first bishop of the Catholic Archdiocese of Ottawa, Joseph-Bruno Guigues. Placed under the direction of the Oblates of Mary Immaculate, it was renamed the College of Ottawa in 1861 and received university status five years later through a royal charter. On 5 February 1889, the university was granted a pontifical charter by Pope Leo XIII, elevating the institution to a pontifical university. The university was reorganized on July 1, 1965, as a corporation, independent from any outside body or religious organization. As a result, the civil and pontifical charters were kept by the newly created Saint Paul University, federated with the university. The remaining civil faculties were retained by the reorganized university.
