Historically a part of Lancashire, the urbanisation and expansion of Liverpool were both largely brought about by the city's status as a major port. By the 18th century, trade from the West Indies, Ireland and mainland Europe coupled with close links with the Atlantic Slave Trade furthered the economic expansion of Liverpool. By the early 19th century, 40% of the world's trade passed through Liverpool's docks, contributing to Liverpool's rise as a major city.
Inhabitants of Liverpool are referred to as Liverpudlians but are also colloquially known as "Scousers", in reference to the local dish known as "scouse", a form of stew. The word "Scouse" has also become synonymous with the Liverpool accent and dialect. Liverpool's status as a port city has contributed to its diverse population, which, historically, were drawn from a wide range of peoples, cultures, and religions, particularly those from Ireland. The city is also home to the oldest Black African community in the country and the oldest Chinese community in Europe.
The popularity of The Beatles, Gerry and the Pacemakers and the other groups from the Merseybeat era contributes to Liverpool's status as a tourist destination; tourism forms a significant part of the city's modern economy. The city celebrated its 800th anniversary in 2007, and it held the European Capital of Culture title together with Stavanger, Norway, in 2008.
Several areas of the city centre were granted World Heritage Site status by UNESCO in 2004. Referred to as the Liverpool Maritime Mercantile City, the site comprises six separate locations in the city including the Pier Head, Albert Dock and William Brown Street and includes many of the city's most famous landmarks.
Liverpool is also the home of two Premier League football clubs, Liverpool F.C. and Everton F.C. Matches between the two clubs are known as the Merseyside derby. Both clubs have had a successful record throughout history, both in results and in producing England players born in the city. Liverpool F.C. is also the English club with the most European titles.
