The University of Edinburgh was founded in 1582 in Edinburgh, Scotland, and was originally known as Tounis College. The institution was founded as a college of law and, until 1858, was governed by the Town Council of the city. In 1935 the Faculty of Divinity of the University of Edinburgh and New College merged, representing the first change to the university's constitution. Another merger followed in 1951, this time with the Royal Dick Veterinary School. In 1998 Edinburgh expanded again, this time merging with Moray House Institute of Education. In 2002 the University underwent a restructuring process that saw Faculties abolished, and the creation of the College of Humanities & Social Science, the College of Medicine & Veterinary Medicine and the College of Science & Engineering. Departments became Schools within the new Colleges.
