British diaspora
Global dispersion of people with British Isles ancestry.
The British diaspora comprises people of English, Scottish, Welsh, Northern Irish, Cornish, Manx and Channel Islands ancestral descent who live outside the United Kingdom and its Crown Dependencies. It includes about 200 million people worldwide, with significant populations in former British Empire territories such as Australia, Canada, New Zealand, and the United States, as well as in countries like Argentina and India. The diaspora has shaped global demographics, culture, and politics through centuries of migration, from early medieval exoduses to large-scale emigration during the British Empire's expansion.

Lore & Background
The first documented exodus of Britons occurred during the Anglo-Saxon invasion of post-Roman Britannia, when Brythonic-speaking Celts migrated to Brittany. After the Norman Conquest of England in 1066, displaced English nobility settled in Ireland, Scandinavia, and as far as Crimea and Anatolia. Englishmen eventually replaced Scandinavians as the main recruits for the Byzantine Emperor's Varangian Guard. During the Age of Discovery and the British Empire's expansion, especially in the first half of the 19th century, British people became among the earliest and largest groups of European emigrants, with concentrations in Australasia and North America.
Reader's Guide
The British diaspora permanently affected population structures in three continents. In Australia, Canada, and New Zealand, people of British origin became the majority, contributing to these countries' integration into the Anglosphere. In colonies such as India, Southern Rhodesia, Hong Kong, Singapore, Jamaica, Barbados, Malaya, and the Cape Colony, British communities, though numerical minorities, exercised dominant cultural and political influence. The diaspora also spread British sports globally, with sailors and soldiers helping association football become the world's most popular sport. In the United States and Japan, Britons helped establish cricket before it was replaced by baseball. Today, the diaspora includes over 100,000 British expatriates each in the Republic of Ireland, Spain, France, Germany, and the United Arab Emirates.
