The Southend-on-Sea Borough Police is a police force that was established by the county borough of Southend-on-Sea in 1914. This force existed independently until 1969.
In 1969 Southend-on-Sea Borough Police amalgamated with Essex to become the Essex and Southend-on-Sea Joint Constabulary. This merger was campaigned against by the council and the local MPs.[1] The title was shortened to Essex Police in 1974.
