The University of Niš (Serbian: Универзитет у Нишу, Univerzitet u Nišu) is a university located in Niš, Serbia. It was founded in 1965 and it consists of 13 faculties with 1500 teachers, 630 staff and extracurricular staff, and around 30,000 students. Since its foundation the University diploma was acquired by more than 50,000 students, including 1300 foreigners.

The University comprises a university library "Nikola Tesla" and 13 academic units of which the Faculty of Technology is located in Leskovac and the Teacher-Training Faculty in Vranje.

The University of Niš was incorporated as an independent degree-granting institution on June 15, 1965.

Its establishment rounded off an important, in many ways pioneering, period in the more recent history of the town which started in 1960 when the first undergraduate programs commenced in Niš under the academic patronage of the University of Belgrade. They were institutionalized as the faculties of Law & Economics, Medicine, and Engineering, constituting a core from which a more and more complex and richer physiognomy of the University would systematically develop, following the demands of times and life itself.

Paul Sabatier (August 3, 1858 – March 4, 1928), was a French clergyman and historian who produced the first modern biography of St. Francis of Assisi. He is the brother of Auguste Sabatier.

He was born at St. Michel de Chabrillanoux in the Cévennes, and was educated at the faculty of theology in Paris. In 1885 he became vicar of St Nicolas, Strasbourg, but in 1889, declining an offer of preferment which was conditional on his becoming a German subject, he was expelled.

For four years he was pastor of St. Cierge in the Cévennes and then devoted himself entirely to historical research. He had already produced an edition of the Didache, and in November 1893 published his important Life of Francis of Assisi. This book gave a great stimulus to the study of medieval literary and religious documents, especially of such as are connected with the history of the Franciscan Order. In 1908 he delivered the Jowett Lectures on Modernism at the Passmore Edwards Settlement, London.

Paul Sabatier's Life of St. Francis of Assisi was placed upon the Index of Forbidden Books by the Catholic Church because of the unreliable retelling of the saint's story.
