The Lancastrian Brigade was an administrative formation of the British Army from 1948 to 1968.
The Brigade administered the regular infantry regiments of northwest England.
After the Second World War the British Army had fourteen infantry depots, each bearing a letter.
The Lancastrian Brigade was formed on 14 July 1948, combining the depots of eight regiments:[2] Under the Defence Review announced in July, 1957, the infantry of the line was reorganised, and by 1959 the Brigade was reduced to four battalions: From 1958 all regiments in the Brigade adopted a common cap badge: the red rose of Lancaster within a laurel wreath and ensigned by the royal crest, with a scroll inscribed Lancastrian.
From 1960 the Lancastrian Brigade was based at Fulwood Barracks in Lancashire.
