The Suffolk Regiment was an infantry regiment of the line in the British Army with a history dating back to 1685. It saw service for three centuries, participating in many wars and conflicts, including the First and Second World Wars, before being amalgamated with the Royal Norfolk Regiment to form the 1st East Anglian Regiment (Royal Norfolk and Suffolk) in 1959 which, in 1964, was further amalgamated with the 2nd East Anglian Regiment (Duchess of Gloucester's Own Royal Lincolnshire and Northamptonshire), the 3rd East Anglian Regiment (16th/44th Foot) and the Royal Leicestershire Regiment to create the present Royal Anglian Regiment.
