Sheriff principal in the context of "Judiciary of Scotland"

A sheriffdom is a judicial district in Scotland, led by a sheriff principal. Since 1 January 1975, there have been six sheriffdoms. Each sheriffdom is divided into a series of sheriff court districts, and each sheriff court is presided over by a resident or floating sheriff (a legally qualified judge). Sheriffs principal and resident or floating sheriffs are all members of the judiciary of Scotland.

The counties or shires of Scotland (Scottish Gaelic: Siorrachdan na h-Alba) were historic subdivisions of Scotland.

The shires were originally established in the Middle Ages for judicial purposes, being territories over which a sheriff had jurisdiction. They were distinct from the various older mormaerdoms, earldoms and other territories into which Scotland was also divided, which are collectively termed the provinces of Scotland by modern historians. The provinces gradually lost their functions, whereas the shires gradually gained functions. From the 16th century, the shires served as constituencies, electing shire commissioners to the Parliament of Scotland. From 1667 each shire had commissioners of supply responsible for collecting local taxes; the commissioners of supply were subsequently given various local government functions as well. From 1797, the shires also served as areas for organising the militia, which was the responsibility of a lord-lieutenant.

Lanarkshire, also called the County of Lanark (Scottish Gaelic: Siorrachd Lannraig; Scots: Lanrikshire), is a historic county, lieutenancy area and registration county in the Central Lowlands and Southern Uplands of Scotland. The county is no longer used for local government purposes, but gives its name to the two modern council areas of North Lanarkshire and South Lanarkshire.

The county was established as a shire (the area controlled by a sheriff) in the twelfth century, covering most of the basin of the River Clyde. The area was sometimes known as Clydesdale. In the early fifteenth century the western part of the shire was removed to become Renfrewshire. The historic county of Lanarkshire includes Glasgow, but the city had a separate lieutenancy from 1893. A Lanarkshire County Council existed from 1890 until 1975, which was based in Glasgow until 1964 when it moved to Hamilton.

Wigtownshire or the County of Wigtown (Scottish Gaelic: Siorrachd Bhaile na h-Ùige, Scots: Wigtounshire) is one of the historic counties of Scotland, covering an area in the south-west of the country. Until 1975, Wigtownshire was an administrative county used for local government. Since 1975 the area has formed part of Dumfries and Galloway for local government purposes. Wigtownshire continues to be used as a territory for land registration, being a registration county. The historic county is all within the slightly larger Wigtown Area, which is one of the lieutenancy areas of Scotland and was used in local government as the Wigtown District from 1975 to 1996.

Wigtownshire forms the western part of the medieval lordship of Galloway, which retained a degree of autonomy until it was fully absorbed by Scotland in the 13th century. In 1369, the part of Galloway east of the River Cree was placed under the control of a steward and so became known as the Stewartry of Kirkcudbright. The rest of Galloway remained under the authority of a sheriff, and became known as the Shire of Wigtown, or Wigtownshire. The area was also sometimes called West Galloway (Scottish Gaelic: Gallobha-an-iar). The county town was historically Wigtown, with the administrative centre moving to Stranraer, the largest town, following the creation of Wigtownshire County Council in 1890.
