Becontree Hundred
Becontree was an ancient hundred in the south west of the county of Essex, England. Its area has been entirely absorbed by the growth of London; with its name reused in 1921 for the large Becontree estate of the London County Council. Its former area now corresponds to the London Borough of Newham, the London Borough of Barking and Dagenham and parts of the London Borough of Waltham Forest and the London Borough of Redbridge. Its early extent also included parts of what is now the London Borough of Havering.<ref name=becontree_victoria>The hundred of Becontree: Introduction', A History of the County of Essex: Volume 5 (1966).

History
The name is first recorded in the 1086 Domesday Book as Beuentreu, meaning tree of a man called Beohha. The original tree, at Becontree Heath, was the location that early hundred meetings took place. Before 1465 it included the area of Havering liberty, which comprised the parishes of Hornchurch, Romford and Havering-atte-Bower, and thus the hundred meeting place was not originally located on the fringe of the area. After the area of the liberty was removed, the hundred contained the parishes of Barking (including Great Ilford), Dagenham, East Ham, Leyton, Little Ilford, Walthamstow, Wanstead and West Ham.

The hundreds of England declined in administrative use because of the rise of various ad hoc'' boards. By 1894 they were effectively replaced by a system of uniform local government districts, which were consolidated over time and finally replaced in 1965 by the London boroughs which are still in use.
