A Serjeant-at-Law (SL), commonly known simply as a Serjeant, was a member of an order of barristers at the English bar. The position of Serjeant-at-Law (servientes ad legem), or Sergeant-Counter, was centuries old; there are writs dating to 1300 which identify them as descended from figures in France prior to the Norman Conquest. The Serjeants were the oldest formally created order in England, having been brought into existence as a body by Henry II. The order rose during the 16th century as a small, elite group of lawyers who took much of the work in the central common law courts. With the creation of Queen's Counsel (or "Queen's Counsel Extraordinary") during the reign of Elizabeth I, the order gradually began to decline, with each monarch opting to create more King's or Queen's Counsel. The Serjeants' exclusive jurisdictions were ended during the 19th century, and with the Judicature Act 1873 coming into force in 1875, it was felt that there was no need to have such figures, and no more were created. The last Serjeant-at-Law was Serjeant Sullivan (d. 1959). The last purely English Serjeant-at-Law was Lord Lindley (d. 1921).
