County of Sussex

Modern local authority areas
For the governance of a long narrow territory it became practical to divide the county into two sections. The three eastern rapes of Sussex became east Sussex and the three western rapes became west Sussex. This began in 1504, with separate administrations (Quarter Sessions) for east and west, a situation recognised by the County of Sussex Act 1865. Under the Local Government Act 1888, the two divisions became two administrative counties (along with three county boroughs (Brighton, Hastings and, from 1911, Eastbourne) that were independent of the administrative counties).
