Brighton is the major part of the city of Brighton and Hove (formed from the previous towns of Brighton, Hove, Portslade and several other villages) in East Sussex, England on the south coast of Great Britain. For administrative purposes, Brighton and Hove is not part of the non-metropolitan county of East Sussex, but remains part of the ceremonial county of East Sussex, within the historic County of Sussex.
The ancient settlement of Brighthelmstone dates from before Domesday Book (1086), but it emerged as a health resort featuring sea bathing during the 18th century and became a destination for day-trippers from London after the arrival of the railway in 1841. Brighton experienced rapid population growth, reaching a peak of over 160,000 by 1961. Modern Brighton forms part of the Brighton/Worthing/Littlehampton conurbation stretching along the coast, with a population of around 480,000.
