Liverpool is a port city and metropolitan borough in Merseyside, England. It is situated on the eastern side of the Mersey Estuary, near the Irish Sea, 178 miles (286 km) north-west of London. It had a population of 508,961 in 2024 and is the administrative, cultural and economic centre of the Liverpool City Region, a combined authority area with a population of over 1.5 million.
Established as a borough in Lancashire in 1207, Liverpool became significant in the late 17th century when the Port of Liverpool was heavily involved in the Atlantic slave trade. The port also imported cotton for the Lancashire textile mills, and became a major departure point for English and Irish emigrants to North America. Liverpool rose to global economic importance at the forefront of the Industrial Revolution in the 19th century and was home to the first inter-city railway, the first non-combustible warehouse system (the Royal Albert Dock), and a pioneering elevated electrical railway; it was granted city status in 1880 and was moved from Lancashire to the newly created county of Merseyside in 1974. It entered a period of decline in the mid-20th century, which was largely reversed after the European Union selected it as the European Capital of Culture for 2008, reportedly generating over £800 million for the local economy within a year.
