The force was established in 1840 as Warwickshire Constabulary. It did not, however, even cover all the rural areas of the county until 1857. Birmingham, Coventry, Leamington Spa, Stratford-upon-Avon and Warwick originally had their own police forces. The Warwickshire force absorbed Warwick Borough Police in 1875 and Stratford-upon-Avon Borough Police in 1889 with Leamington Borough Police lasting until 1946. In 1969, Coventry City Police amalgamated with Warwickshire Constabulary and the force became Warwickshire and Coventry Constabulary. However, with the inclusion of Coventry in the new county of the West Midlands in 1974, Coventry passed to the new West Midlands Police, which also took over the areas of the Birmingham City Police and part of the northwestern area of Warwickshire (around Solihull and Sutton Coldfield). Warwickshire Constabulary reverted to its old name.
