The University of Glasgow (abbreviated as Glas. in post-nominals; Scottish Gaelic: Oilthigh Ghlaschu) is a public research university in Glasgow, Scotland. Founded by papal bull in 1451 [O.S. 1450], it is the fourth-oldest university in the English-speaking world and one of Scotland's four ancient universities. Along with the universities of St Andrews, Aberdeen, and Edinburgh, the university was part of the Scottish Enlightenment during the 18th century.
