Peerages in the United Kingdom form a legal system comprising both hereditary and lifetime titles, composed of various ranks, and within the framework of the Constitution of the United Kingdom form a constituent part of the legislative process and the British honours system. The British monarch is considered the fount of honour and is notionally the only person who can grant peerages, though there are many conventions about how this power is used, especially at the request of the British government. The term peerage can be used both collectively to refer to the entire body of titled nobility, and individually to refer to a specific title. British peerage title holders are termed peers of the Realm.
Lord is an appellation for a person or deity who has authority, control, or power over others, acting as a master, chief, or ruler. The appellation can also denote certain persons who hold a title of the peerage in the United Kingdom, or are entitled to courtesy titles. The collective "Lords" can refer to a group or body of peers.
Baron is a rank of nobility or title of honour, often hereditary, in various European countries, either current or historical. The female equivalent is baroness. Typically, the title denotes an aristocrat who ranks higher than a lord or knight, but lower than a viscount or count. Often, barons hold their fief – their lands and income – directly from the monarch. Barons are less often the vassals of other nobles. In many kingdoms, they were entitled to wear a smaller form of a crown called a coronet.
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.

The Peerage of England comprises all peerages created in the Kingdom of England before the Act of Union in 1707. From that year, the Peerages of England and Scotland were closed to new creations, and new peers were created in a single Peerage of Great Britain. There are five peerages in the United Kingdom in total. English Peeresses obtained their first seats in the House of Lords under the Peerage Act 1963 from which date until the passage of the House of Lords Act 1999 all Peers of England could sit in the House of Lords.
Marquess of Huntly is a title in the Peerage of Scotland that was created on 17 April 1599 for George Gordon, 6th Earl of Huntly.

The Marquess holds the following subsidiary titles: Lord Gordon of Strathaven and Glenlivet and Earl of Aboyne, and Baron Meldrum, of Morven in the County of Aberdeen.
The Peerage of Great Britain comprises all extant peerages created in the Kingdom of Great Britain between the Acts of Union 1707 and the Acts of Union 1800. It replaced the Peerage of England and the Peerage of Scotland, but was itself replaced by the Peerage of the United Kingdom in 1801.
The Peerage of the United Kingdom is one of the five Peerages in the United Kingdom.

The history of the British peerage, a system of nobility found in the United Kingdom, stretches over the last thousand years. The current form of the British peerage has been a process of development. While the ranks of baron and earl predate the British peerage itself, the ranks of duke and marquess were introduced to England in the 14th century. The rank of viscount came later, in the mid-15th century. Peers were summoned to Parliament, forming the House of Lords.
The British peerage is governed by a body of law that has developed over several centuries. Much of this law has been established by a few important cases, and some of the more significant of these are addressed in this article.
In the United Kingdom, life peers are appointed members of the peerage whose titles cannot be inherited, in contrast to hereditary peers. Life peers are appointed by the monarch on the advice of the prime minister. With the exception of the Dukedom of Edinburgh awarded for life to Prince Edward in 2023, all life peerages conferred since 2009 have been created under the Life Peerages Act 1958 with the rank of baron and entitle their holders to sit and vote in the House of Lords, presuming they meet qualifications such as age and citizenship. The legitimate children of a life peer appointed under the Life Peerages Act 1958 are entitled to style themselves with the prefix "The Honourable", although they cannot inherit the peerage itself. Prior to 2009, life peers of baronial rank could also be so created under the Appellate Jurisdiction Act 1876 for senior judges.
The British nobility is made up of the peerage and the (landed) gentry. The nobility of its four constituent home nations has played a major role in shaping the history of the country, although the hereditary peerage now retain only the rights to stand for election to the House of Lords, dining rights there, position in the formal order of precedence, the right to certain titles, and the right to an audience with the monarch.
An Earl/Marquis/Duke in the Baronage of Scotland is an ancient title of nobility that is held en baroneum, which means that its holder, who is a earl/marquis/duke in the Baronage of Scotland, is also always a baron. The holder may or may not be a Lord of Regality, which meant that the holder was appointed by the Crown and had the power of "pit and gallows", meaning the power to authorise the death sentence.
By-elections to the House of Lords occur when vacancies arise among seats assigned to hereditary peers due to death, resignation, or disqualification. Candidates for these by-elections are limited to holders of hereditary peerages, and their electorates are made up of sitting Lords; in most cases the electorate are those sitting hereditary peers of the same party affiliation as the departed peer.
