Liège is, with 194,054 inhabitants as of , the second most populous city in Wallonia after Charleroi.
The name in Latin 'Leodium' points clearly to the Germanic word 'leod' = people. Around 705, Saint Lambert of Maastricht is credited with completing the Christianization of the region, indicating that up to the early 8th-century, the religious practices of antiquity had survived in some form.
Thalys and ICE high-speed trains serve Brussels, Paris, Aachen, Cologne and Frankfurt.
In the 19th century it became an early centre of industrialism.
The Liège municipality includes the former communes of Angleur, Bressoux, Chênée, Glain, Grivegnée, Jupille-sur-Meuse, Rocourt, and Wandre.
The city is the principal economic and cultural centre of Wallonia.
In 1920 the prefix Royal was added to the name of the club that already had won 3 championships (1896, 1898, 1899).
In 19, the RFC Liège won two more championships, being at that time the only team which was able to contest the undisputed domination of Anderlecht. The club went down from the first division (which it hadn't left since 1945) to the third division.
