Trinity College (full name: The College of the Holy and Undivided Trinity in the University of Oxford, of the foundation of Sir Thomas Pope (Knight)) is one of the constituent colleges of the University of Oxford in England. The college was founded in 1555 by Sir Thomas Pope, on land previously occupied by Durham College, home to Benedictine monks from Durham Cathedral. Trinity has produced three British prime ministers, placing it third after Christ Church and Balliol in terms of former students who have held that office.
