Notting Hill is an affluent district of West London, England, in the Royal Borough of Kensington and Chelsea. Notting Hill is known for being a cosmopolitan and multicultural neighbourhood, hosting the annual Notting Hill Carnival and Portobello Road Market.From around 1870, Notting Hill had an association with artists.For much of the 20th century, the large houses were subdivided into multi-occupancy rentals. Caribbean immigrants were drawn to the area in the 1950s, partly because of the cheap rents, but were exploited by slum landlords like Peter Rachman and also became the target of white Teddy Boys in the 1958 Notting Hill race riots. Then known for its slum housing, in the early 21st century, after decades of gentrification, Notting Hill has a reputation as an affluent and fashionable area, known for attractive terraces of large Victorian townhouses and high-end shopping and restaurants (particularly around Westbourne Grove and Clarendon Cross). A Daily Telegraph article in 2004 used the phrase "the Notting Hill Set" to refer to a group of emerging Conservative politicians, such as David Cameron and George Osborne, who would become respectively Prime Minister and Chancellor of the Exchequer and were once based in Notting Hill.
