District in the London Borough of Bromley.
Until the coming of the railway in 1857, Beckenham was a small village in the county of Kent with almost completely rural surroundings: once a family of entrepreneurs began the building of villas here, its population soared from 2000 to 26,000 during 1850-1900 and throughout the rest of the century.
The Municipal Borough of Beckenham came into being in 1935. It took over from what had been, since 1894, Beckenham Urban District Council and included parts of Hayes and West Wickham, previously part of Bromley Rural District Council. The new Borough status reflected the growth of Beckenham in less than fifty years.[
In 1965, as part of the creation of the Greater London Council, the Borough council was disbanded and Beckenham came under control of the newly constituted London Borough of Bromley. Councillors represent various parts of the Borough of Beckenham. Beckenham Town Centre Management coordinates business interests in the town.The Wikipedia page is [1].
