British nationality law in the context of "Modern immigration to the United Kingdom"

British people or Britons, also known colloquially as Brits, are the citizens and diaspora of the United Kingdom, the British Overseas Territories, and the Crown dependencies. British nationality law governs modern British citizenship and nationality, which can be acquired, for instance, by descent from British nationals. When used in a historical context, "British" or "Britons" can refer to the Ancient Britons, the Celtic-speaking inhabitants of Great Britain during the Iron Age, whose descendants formed the major part of the modern Welsh people, Cornish people, Bretons and considerable proportions of English people. It also refers to those British subjects born in parts of the former British Empire that are now independent countries who settled in the United Kingdom prior to 1973.

Though early assertions of being British date from the Late Middle Ages, the Union of the Crowns in 1603 and the creation of the Kingdom of Great Britain in 1707 triggered a sense of British national identity. The notion of Britishness and a shared British identity was forged during the 18th century and early 19th century when Britain engaged in several global conflicts with France, and developed further during the Victorian era. The complex history of the formation of the United Kingdom created a "particular sense of nationhood and belonging" in Great Britain; Britishness became "superimposed on much older identities", of English, Scots and Welsh cultures, whose distinctiveness still resists notions of a homogenised British identity. Because of longstanding ethno-sectarian divisions, British identity in Northern Ireland is controversial, but it is held with strong conviction by Unionists.

Thomas Stearns Eliot OM (26 September 1888 – 4 January 1965) was a poet, essayist and playwright. He was a leading figure in English-language Modernist poetry where he reinvigorated the art through his use of language, writing style, and verse structure. He is also noted for his critical essays, which often re-evaluated long-held cultural beliefs.

Born in St. Louis, Missouri, United States, to a prominent Boston Brahmin family, he moved to England in 1914 at the age of 25 and went on to settle, work, and marry there. He became a British subject in 1927 at the age of 39 and renounced his American citizenship.

Gibraltarians (Spanish: gibraltareños, colloquially: llanitos) are a sub-national group who live in Gibraltar, a British overseas territory situated near the southern tip of the Iberian Peninsula, close to Spain, at the entrance to the Mediterranean Sea. Gibraltarians hold British citizenship.

The Welsh (Welsh: Cymry) are an ethnic group and nation native to Wales who share a common ancestry, history and culture. Wales is one of the four countries of the United Kingdom. The majority of people living in Wales are British citizens.

In Wales, the Welsh language (Welsh: Cymraeg) is protected by law. Welsh remains the predominant language in many parts of Wales, particularly in North Wales and parts of West Wales, though English is the predominant language in South Wales. The Welsh language is also taught in schools in Wales; and, even in regions of Wales in which Welsh people predominantly speak English on a daily basis, the Welsh language is spoken at home among family or in informal settings, with Welsh speakers often engaging in code-switching and translanguaging. In the English-speaking areas of Wales, many Welsh people are bilingually fluent or semi-fluent in the Welsh language or, to varying degrees, capable of speaking or understanding the language at limited or conversational proficiency levels. The Welsh language is descended from Brythonic, spoken across Britain since before the Roman invasion.

The term "British subject" has several different meanings depending on the period. Before 1949, it referred to almost all people in the British Empire (including the United Kingdom, Dominions, and colonies, but excluding protectorates and protected states). Between 1949 and 1983, the term was synonymous with Commonwealth citizen. Currently, it refers to people possessing a class of British nationality largely granted under limited circumstances to those connected with Ireland or British India born before 1949. Individuals with this nationality are British nationals and Commonwealth citizens, but not British citizens.

The status under the current definition does not automatically grant the holder right of abode in the United Kingdom but almost all British subjects do have this entitlement. As of 2025, about 20,400 British subjects hold valid British passports with this status and enjoy consular protection when travelling abroad; about 800 do not have right of abode in the UK.

A British protected person (BPP) is a member of a class of British nationality associated with former protectorates, protected states, and territorial mandates and trusts under British control. Individuals with this nationality are British nationals, but are neither British nor Commonwealth citizens. Nationals of this class are subject to immigration controls when entering the United Kingdom and do not have the automatic right of abode there or any other country.

This nationality was created to accommodate residents of areas that were under British protection or administration but were not British possessions (as colonies were) or Dominions of the Crown. As of 2025, about 1,100 British protected persons hold valid British passports with this status and enjoy consular protection when travelling abroad. However, individuals who only hold BPP nationality are effectively stateless as they are not guaranteed the right to enter the country by which they are protected.
