Provosts in Scotland

A provost (introduced into Scots from French) is the ceremonial head of many Scottish local authorities, and under the name prévôt (French pronunciation: ​[pʁeˈvoː]) was a governmental position of varying importance in Ancien Régime France.

As a secular title, praepositus is also very old, dating to the praepositus sacri cubiculi of the late Roman Empire, and the praepositus palatii of the Carolingian court. The title developed in France from where it found its way into Scots, where in Scotland it became the style (as provost) of the principal magistrates of the Royal Burghs (roughly speaking, the equivalent of "mayor" in the rest of the UK) ("Lord Provost" in Edinburgh, Glasgow, Aberdeen and Dundee), and into England, where it is applied to certain officers charged with the maintenance of military discipline. A Provost Marshal is an officer of the army originally appointed when troops are on service abroad (and now in the United Kingdom as well) for the prompt repression of all offenses. He may at any time arrest and detain for trial persons subject to military law committing offences, and may also carry into execution any punishments to be inflicted in pursuance of a court martial (Army Act 1881, § 74). A provost sergeant is in charge of the garrison police or regimental police. The 'Provost' also refers to the military police in general. The British Army pronunciation is 'Prov-oh', though the U.S. Army pronunciation is 'Pro-vost' as written.
