North and West European
The population of Northern and Western Europe mainly includes German, French, and Dutch people.
Britain – specifically the eastern region of the British Isles – has been populated continuously for at least the past 15,000 years, with recent ethnic stock (from before the 11th century) including pre-Celts, Celts, Romans, Anglo-Saxons, Norse, and Normans. More recently – that is, since the Middle Ages – other ethnicities migrated to Britain, whether by invitation (European Jews in 1070, by William the Conqueror, though they were expelled about 200 years later), by virtue of the African slave trade (dating back to the 1730s CE), or trade (including the oldest Chinese community in Europe, dating back to the 19th century).
People of Eastern European descent trace their roots to Russia, Ukraine, Poland, and Hungary. The early Common Era saw the region largely populated by Slavic and Baltic tribes with later Roman, Mongol, and Ottoman invasions. Bridging Europe to Asia, the region has been the epicenter of rich cultural diffusion; arts and sciences have flourished there despite the often inhospitable climate and political upheavals over the last couple of centuries.
Nigeria has the largest population in Africa and its people belong to over 250 sub-ethnic groups, the largest of which are the Esan and the Yoruba. Nigeria was ruled by various kingdoms and tribal rulers and became a colony of England in the 19th century.
