The Peerage of Ireland consists of those titles of nobility created by the English monarchs in their capacity as Lord or King of Ireland, or later by monarchs of the United Kingdom of Great Britain and Ireland. It is one of the five divisions of Peerages in the United Kingdom. The creation of such titles came to an end in the 19th century. The ranks of the Irish peerage are duke, marquess, earl, viscount and baron. As of 2016, there were 135 titles in the Peerage of Ireland extant: two dukedoms, ten marquessates, 43 earldoms, 28 viscountcies, and 52 baronies. However, these titles have no official recognition in Ireland, with Article 40.2 of the Constitution of Ireland forbidding the state conferring titles of nobility and stating that an Irish citizen may not accept titles of nobility or honour except with the prior approval of the Irish government.

Earl of Rothes is a title in the Peerage of Scotland. It was created in 1458 for George Leslie, 1st Lord Leslie. He had already been created Lord Leslie in 1445, also in the Peerage of Scotland. His grandson, the third Earl, having only succeeded his elder brother in March 1513, was killed at the Battle of Flodden on 9 September of the same year. His son, the fourth Earl, served as an Extraordinary Lord of Session. Lord Rothes was also tried for the murder of Cardinal Beaton but was acquitted.
Earl of Haddington is a title in the Peerage of Scotland. It was created in 1627 for the noted Scottish lawyer and judge Thomas Hamilton, 1st Earl of Melrose. He was Lord President of the Court of Session from 1616 to 1625. Hamilton had already been created Lord Binning in 1613 and Lord Binning and Byres, in the County of Haddington, and Earl of Melrose, in the County of Roxburgh, in 1619. These titles were also in the Peerage of Scotland. The title of the earldom derived from the fact that he was in possession of much of the lands of the former Melrose Abbey. However, Hamilton was unhappy with this title and wished to replace it with "Haddington". In 1627 he relinquished the earldom of Melrose and was instead created Earl of Haddington, with the precedence of 1619 and with limitation to his heirs male bearing the surname of Hamilton. This derived from the fact that he considered it a greater honour to take his title from a county rather than from an abbey. Hamilton was a member of the prominent Scottish family of that name and descended from John de Hamilton, younger son of Walter de Hamilton, who was granted the feudal barony of Cadzow and who is also the ancestor of the Dukes of Hamilton and Dukes of Abercorn.
