Did you know?

Police forces as we now understand them did not exist until the 19th century. Before that policing was carried out by locally employed watchmen, constables and magistrates.

The first modern police force in England was the Metropolitan Police Force, created in 1829. Provincial police forces in England and Wales did not begin until after the County Police Act of 1839.

Nearly all the Metropolitan Police staff records detail:

  • name
  • rank
  • warrant number
  • division
  • dates of appointment and removal

The Irish Constabulary (Ireland) Act 1836 created a single, unified police force responsible for the whole of Ireland, except Dublin. In 1867 it was renamed the Royal Irish Constabulary. This was disbanded in 1922. From 1922 to 2001 the police force in Northern Ireland was the Royal Ulster Constabulary.

Records of other police forces (except the Royal Irish Constabulary) are not public records. Those which survive are held either by:

  • the appropriate local record office
  • the force itself
