The term Spanish people (or Spaniards) has two distinct meanings: Traditionally, it applies to people native to any part of Spain. More recently, it has also come to have a legal meaning, referring to people who hold Spanish citizenship.

Within Spain there are a number of nationalisms and regionalisms, reflecting the country's complex history. The official language of Spain is Spanish (also known as Castilian), a standard language based on the mediaeval dialect of the Castilians of north-central Spain. There are several commonly spoken regional languages. With the exception of Basque, the languages native to Spain are Romance languages.

There are substantial populations outside Spain with ancestors who emigrated from Spain; most notably in Latin America.

The earliest modern humans inhabiting Spain are believed to have been Neolithic peoples who may have arrived in the Iberian Peninsula as early as 35,000­–40,000 years ago. In more recent times the Iberians are believed to have arrived or developed in the region between the 4th millennium BC and the 3rd millennium BC, initially settling along the Mediterranean coast. Celts settled in Spain during the Iron Age. Some of those tribes in North-central Spain, which had cultural contact with the Iberians, are called Celtiberians. In addition, a group known as the Tartessians and later Turdetanians inhabited southwestern Spain and who are believed to have developed a separate civilization of Phoenician influence. The seafaring Phoenicians, Greeks, and Carthaginians successively founded trading colonies along the Mediterranean coast over a period of several centuries. The Second Punic War between the Carthaginians and Romans was fought mainly in what is now Spain and Portugal.

Black Irish is an ambiguous term used mainly outside of Ireland.^{[citation needed]} Over the course of history, and in different parts of the Irish diaspora throughout the world, it has been subject to several different although somewhat overlapping meanings, encompassing physical appearance, religious affiliation, ethnicity, subculture and poverty. Modern traditionalists, however, maintain the term to be synonymous with a dark-haired phenotype exhibited by certain individuals originally descended from Ireland. Opinions vary in regard to what is perceived as the usual physical characteristics of the so-called Black Irish: e.g., dark hair, brown eyes and medium skin tone; or dark hair, blue or green eyes and fair skin tone. Unbeknown to some who have used this term at one time or another^{[citation needed]}, dark hair in people of Irish descent is extremely common, although darker skin complexions appear less frequently.

Early 21st century genetic studies have provided new insights into the origins of Irish people as well as their neighbours in the British Isles. Correspondingly, researchers in the field have suggested that migrations from Prehistoric Iberia (Spain, Portugal and also the Basque region) can be viewed as the primary source for their genetic material,^{[citation needed]} having demonstrated marked similarities with modern representatives of the aforementioned time period in that of the Basque people. However, the majority of Irish males fall under the R1b sub-clade L-21, which is quite rare for Basques.

British people (also referred to as the British, Britons, or informally as Brits or Britishers) are citizens or natives of the United Kingdom, of the Isle of Man, of any of the Channel Islands, or of any of the British overseas territories, and their descendants.British nationality law governs modern British citizenship and nationality, which can be acquired, for instance, by birth in the UK or by descent from British nationals. When used in a historical context, the term British people refers to the ancient Britons, the indigenous inhabitants of Great Britain south of the Forth.

Although early assertions of being British date from the Late Middle Ages, the creation of the Kingdom of Great Britain in 1707 triggered a sense of British national identity. The notion of Britishness was forged during the Napoleonic Wars between Britain and the First French Empire, 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 resist 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.
