Life peer in the context of "John Bird, Baron Bird"

The House of Lords is the upper house of the Parliament of the United Kingdom. Like the lower house, the House of Commons, it meets in the Palace of Westminster in London, England. One of the oldest extant institutions in the world, its origins lie in the early 11th century and the emergence of bicameralism in the 13th century.

In contrast to the House of Commons, membership of the Lords is not generally acquired by election. Most members are appointed for life, on either a political or non-political basis. Hereditary membership was limited in 1999 to 92 excepted hereditary peers: 90 elected through internal by-elections, plus the Earl Marshal and the Lord Great Chamberlain as members ex officio, the sole two officers to directly inherit their seats. The House of Lords also includes up to 26 archbishops and bishops of the Church of England, known as Lords Spiritual. Since 2014, membership may be voluntarily relinquished or terminated upon expulsion.

Nobility is a social class found in many societies that have an aristocracy. It is normally appointed by and ranked immediately below royalty. Nobility has often been an estate of the realm with many exclusive functions and characteristics. The characteristics associated with nobility may constitute substantial advantages over or relative to non-nobles or simply formal functions (e.g., precedence), and vary by country and by era. Membership in the nobility, including rights and responsibilities, is typically hereditary and patrilineal.

Membership in the nobility has historically been granted by a monarch or government, and acquisition of sufficient power, wealth, ownerships, or royal favour has occasionally enabled commoners to ascend into the nobility.

A Peerage is a form of crown distinction, with Peerages in the United Kingdom comprising both hereditary and lifetime titled appointments of various ranks, which form both a constituent part of the legislative process and the British honours system within the framework of the Constitution of the United Kingdom.

The peerage forms the highest rung of what is termed the "British nobility". The term peerage can be used both collectively to refer to this entire body of titled nobility (or a subdivision thereof), and individually to refer to a specific title (modern English language-style using an initial capital in the latter case but not the former). British peerage title holders are termed peers of the Realm. "Lord" is used as a generic term to denote members of the peerage; however, individuals who use the appellation Lord or Lady are not always necessarily peers (for example some judicial, ecclesiastic and others are often accorded the appellation "Lord" or "Lady" as a form of courtesy title as a product of their office).

The Peerage of the United Kingdom is one of the five peerages in the United Kingdom. It comprises most peerages created in the United Kingdom of Great Britain and Ireland after the Acts of Union in 1801, when it replaced the Peerage of Great Britain. New peers continued to be created in the Peerage of Ireland until 1898 (the last creation was the Barony of Curzon of Kedleston).

The House of Lords Act 1999 reformed the House of Lords. Until then, all peers of the United Kingdom were automatically members of the House of Lords. However, from that date, most of the hereditary peers ceased to be members, whereas the life peers retained their seats. All hereditary peers of the first creation (i.e. those for whom a peerage was originally created, as opposed to those who inherited a peerage), and all surviving hereditary peers who had served as Leader of the House of Lords, were offered a life peerage to allow them to continue to sit in the House, should they wish.

A peerage is a legal system historically comprising various hereditary titles (and sometimes non-hereditary titles) in a number of countries, and composed of assorted noble ranks.

The House of Lords Act 1999 (c. 34) is an act of the Parliament of the United Kingdom which reformed the House of Lords, one of the chambers of Parliament. The Act was given royal assent on 11 November 1999. For centuries, the House of Lords had included several hundred members who inherited their seats (hereditary peers); the Act removed such a right. However, as part of a compromise, the Act allowed ninety-two hereditary peers to remain in the House. Another ten were created life peers to enable them to remain in the House.

The Act decreased the membership of the House from 1,330 in October 1999 to 669 in March 2000. As another result of the Act, the majority of the Lords were thence life peers, whose numbers had been gradually increasing since the Life Peerages Act 1958. As of June 2023, there were 825 members of the House of Lords, of whom 24 were senior Church of England bishops, whose representation in the House is governed by the Lords Spiritual (Women) Act 2015.
