Duke of Rothesay in the context of "Earl of Carrick"

The Forth Bridge is a cantilever railway bridge across the Firth of Forth in the east of Scotland, 9 miles (14 kilometres) west of central Edinburgh. Completed in 1890, it is considered a symbol of Scotland (having been voted Scotland's greatest man-made wonder in 2016), and is a UNESCO World Heritage Site. It was designed by English engineers Sir John Fowler and Sir Benjamin Baker. It is sometimes referred to as the Forth Rail Bridge (to distinguish it from the adjacent Forth Road Bridge), although this is not its official name.

Construction of the bridge began in 1882 and it was opened on 4 March 1890 by the Duke of Rothesay, the future Edward VII. The bridge carries the Edinburgh–Aberdeen line across the Forth between the villages of South Queensferry and North Queensferry and has a total length of 2,467 metres (8,094 ft). When it opened it had the longest single cantilever bridge span in the world, until 1919 when the single 1,801 ft (549 m) span Quebec Bridge in Canada was completed. It continues to be the world's second-longest single cantilever span, with two spans of 1,709 feet (521 m).

Prince and Great Steward of Scotland (Scottish Gaelic: Prionnsa agus Mòr-stiùbhard na h-Alba; Scots: Prince an Great Stewart o Scotland) is one of the titles of the heir apparent to the British throne. The holder since 8 September 2022 is Prince William, who bears the other Scottish titles of Duke of Rothesay, Earl of Carrick, Lord of the Isles and Baron of Renfrew.

The Peerage of Scotland (Scottish Gaelic: Moraireachd na h-Alba; Scots: Peerage o Scotland) is one of the five divisions of peerages in the United Kingdom and for those peers created by the King of Scotland before 1707. Following that year's Treaty of Union, the Kingdom of Scotland and the Kingdom of England were combined under the name of Great Britain, and a new Peerage of Great Britain was introduced in which subsequent titles were created.

As of November 2025, there are 74 peers of Scotland: 8 dukes (including one royal duke: the Duke of Rothesay), 4 marquesses, 39 earls, 3 viscounts and 20 lords of Parliament (counting peers known by a higher-ranking title in one of the other peerages).

Lord of the Isles or King of the Isles (Scottish Gaelic: Triath nan Eilean or Rìgh Innse Gall; Latin: Dominus Insularum) is a title of nobility in the Baronage of Scotland with historical roots that go back beyond the Kingdom of Scotland. It began with Somerled in the 12th century and thereafter the title was held by a series of his descendants, the Norse-Gaelic rulers of the Isle of Man and Argyll and the islands of Scotland in the Middle Ages. They wielded sea-power with fleets of galleys (birlinns). Although they were, at times, nominal vassals of the kings of Norway, Ireland, or Scotland, the island chiefs remained functionally independent for many centuries. Their territory included much of Argyll, the Isles of Arran, Bute, Islay, the Isle of Man, Hebrides (Skye and Ross from 1438), Knoydart, Ardnamurchan, and the Kintyre peninsula. At their height they were the greatest landowners and most powerful lords after the kings of England and Scotland.

The end of the MacDonald Lords came in 1493 when John MacDonald II had his ancestral homeland, estates, and titles seized by King James IV of Scotland. After that time, the MacDonald Clan contested the right of James IV to the Lordship of the Isles and uprisings and rebellions against the Scottish monarch were common. More recently, the Lordship of the Isles has been held by the Duke of Rothesay, the eldest son and heir apparent of the King of Scots, a title which, since the creation of the Kingdom of Great Britain, is usually borne by the Prince of Wales. Thus Prince William is the current Lord of the Isles.

Baron of Renfrew (Scottish Gaelic: Baran Rinn Friù) is a dignity in the Baronage of Scotland held by the heir apparent to the British throne, currently Prince William, Duke of Rothesay. It has been held by the Scottish heir apparent since 1404. It is closely associated with the title Duke of Rothesay. An act of the Scottish Parliament passed in 1469 confirmed the pattern of succession. Renfrew, a town near Glasgow, is sometimes called the "cradle of the royal Stewarts".

In Scotland, barons hold titles in the Baronage of Scotland, not peerages: a Scottish Lord of Parliament equates to an English or British baron. Some, however, claim that the Act of 1469 effectively elevated the Barony of Renfrew to the dignity of a peerage. Others suggest that the barony became a peerage upon the Union of the Crowns in 1603. Finally, some scholars argue that the uncertainty surrounding the text of the 1469 Act leaves the barony as only a baronage dignity, not a peerage dignity. The official position is given in Hansard (House of Lords – written answers) for 18 May 1999: "The Barony of Renfrew is not a peerage dignity at all; it is a feudal or minor barony of Scotland." Note that since the abolition of feudalism in 2004 these feudal titles became personal baronage titles.
