British people (also referred to as Britons, informally as Brits, or archaically as Britishers) are citizens or natives of the United Kingdom, Crown Dependencies, British Overseas Territories, and their descendants. 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 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 unified 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.
Historical reenactment is a scripted educational or entertainment activity in which participants follow a prearranged plan to recreate some aspects of a historical event or period, very often a military engagement or display. This may be as narrow as a specific moment from a battle, such as the reenactment of Pickett's Charge at the Great Reunion of 1913, or as broad as an entire period, such as Regency reenactment or The 1920s Berlin Project.
