The inhabited islands of the Channel Islands are Jersey, Guernsey, Alderney, Sark, Herm (the main islands); Jethou, Brecqhou (Brechou), and Lihou.
Culturally, the Norman language predominated in the islands until the 19th century, when increasing influence from English-speaking settlers and easier transport links led to Anglicisation. There are four main dialects/languages of Norman in the islands, Auregnais (Alderney, extinct in late 20th century), Dgèrnésiais (Guernsey), Jèrriais (Jersey) and Sarkese (Sark, an offshoot of Jèrriais).
Victor Hugo spent many years in exile, first in Jersey and then in Guernsey where he wrote Les Misérables. Guernsey is also the setting of Hugo's later novel, Les Travailleurs De La Mer (The Toilers of the Sea). A 'Guernsey-man' also makes an appearance in Herman Melville's Moby-Dick.
The annual 'Muratti', the inter-island football match, is considered the sporting event of the year - although, thanks to broadcast coverage, it no longer attracts the crowds of spectators, travelling between the islands, that occurred during the 20th century.
Channel Island sportsmen and women compete in the Commonwealth Games for their respective islands, and the islands have been enthusiastic supporters of the Island Games. Shooting is a popular sport - islanders have won Commonwealth medals in this discipline.
