is a crown worn on the epaulettes, the same as a major in the British Army. Metropolitan Police The rank of superintendent was introduced at the foundation of the Metropolitan Police in 1829. Each division was commanded by a superintendent. The rank below superintendent was originally inspector until the introduction of chief inspector in 1868. Originally, only the commissioners held a higher rank than superintendent (and they were not sworn police officers). In 1839, Captain William Hay was appointed to the new rank of inspecting superintendent, replaced by assistant commissioner in 1856. The rank of district superintendent was introduced between superintendent and assistant commissioner in 1869, and was renamed chief constable in 1886. The rank of superintendent was also adopted in the Detective Branch (later the Criminal Investigation Department) from 1868, when Adolphus Williamson, the first head of the branch, was promoted to the rank. In 1949, Metropolitan Police superintendents were regraded to the new rank of chief superintendent, chief inspectors were regraded to superintendent, and sub-divisional inspectors and divisional detective inspectors were regraded to chief inspector (with those ranks being abolished). In September 1953, there was another change, when the rank was split into superintendent grade I (current superintendents, chief inspectors commanding sub-divisions and detective chief inspectors commanding divisional CIDs) and superintendent grade II (other current chief inspectors), with a redefined rank of chief inspector being created for senior inspectors. Superintendents grade II wore the crown (the rank badge formerly worn by chief inspectors), with superintendents grade I wearing a crown over a pip (the rank badge formerly worn by superintendents). This lasted until 1974, when superintendent once more became a single rank, wearing a crown on the epaulettes. From January 1954 there was one superintendent grade I and one chief inspector in each sub-division, one chief superintendent, one superintendent grade II and one detective superintendent grade I in each division, and one commander, one deputy commander, one detective chief superintendent, and one detective superintendent grade II in each district. A detective chief inspector was added in each division later in 1954. Other British forces In most other forces, superintendent lay between inspector and assistant chief constable until well into the 20th century. In many smaller forces, the senior superintendent was also the ACC. Some forces had chief inspectors, and some later acquired chief superintendents, but this was by no means universal. Today, however, every force in the country
