One of Scotland's four ancient institutions, the University of Glasgow (Scottish Gaelic: Oilthigh Ghlaschu; Latin: Universitas Glasguensis) is the fourth-oldest university in the English-speaking world. In 1451, it was founded. The University, along with the University of Edinburgh, participated in the Scottish Enlightenment in the 18th century. It presently belongs to the global network of research universities known as Universitas 21. Similar to universities from the pre-modern era, Glasgow initially served the needs of students from affluent backgrounds. However, in the 19th century, it distinguished itself as a leader in British higher education by also serving the needs of students from the expanding urban and commercial middle class. Glasgow helped all of these students by educating them for careers in the legal, medical, government, educational, and religious spheres. A smaller but growing number of people were also trained for vocations in science and engineering. The main University campus was formerly situated on the city's High Street, but since 1870 it has been situated at Gilmorehill in the city's West End. Other locations for university buildings include the Crichton Campus in Dumfries and the University Marine Biological Station Millport on the Island of Cumbrae in the Firth of Clyde. https://www.gla.ac.uk/international/englishlanguage/pre-sessionalenglishcourses/
