Glasgow is the most populous city in Scotland, located on the banks of the River Clyde in west central Scotland. It is the fourth-most populous city in the United Kingdom and the 27th-most populous city in Europe, and comprises 23 wards which represent the areas of the city within Glasgow City Council. Glasgow is a leading city in Scotland for finance, shopping, industry, culture and fashion, and was commonly referred to as the "second city of the British Empire" for much of the Victorian and Edwardian eras.
In 2020, it had an estimated population as a defined locality of 632,350. More than 1,000,000 people live in the Greater Glasgow contiguous urban area, while the wider Glasgow City Region is home to more than 1,800,000 people (its defined functional urban area total was almost the same in 2020), around a third of Scotland's population. The city has a population density of 3,562 people per km, much higher than the average of 70/km for Scotland as a whole. Glasgow grew from a small rural settlement close to Glasgow Cathedral and descending to the River Clyde to become the largest seaport in Scotland, and the tenth-largest by tonnage in Britain. Expanding from the medieval bishopric and episcopal burgh (subsequently royal burgh), and the later establishment of the University of Glasgow in the 15th century, it became a major centre of the Scottish Enlightenment in the 18th century.
