The study of law at the University of Cambridge began in the thirteenth century. The faculty sits the oldest law professorship in the English-speaking world, the Regius Professorship of Civil Law, which was founded by Henry VIII in 1540 with a stipend of £40 per year for which the holder is still chosen by The Crown. Today, the faculty incorporates the Institute of Criminology as well as 11 Research Centres, including the world's leading research institute for international law, The Lauterpacht Centre for International Law. The faculty has 31 professors, six readers, and over 70 other university, faculty and college teaching officers. The student body comprises about 700 undergraduate and 250 postgraduate students. It is also home to the Cambridge University Law Society, the largest student-run law society in the United Kingdom and among the largest in the world.
