People of Scotland.

Ethnic groups.

For many centuries continual strife characterized relations between the Celtic Scots of the Highlands and the western islands and the Anglo-Saxons of the Lowlands. Only since the 20th century has the mixture been widely seen as a basis for a rich unified Scottish culture; the people of Shetland and Orkney have tended to remain apart from both of these elements and to look to Scandinavia as the mirror of their Norse heritage. Important immigrant groups have arrived, most notably Irish labourers; there have also been significant groups of Jews, Lithuanians, Italians, and, after World War II, Poles and others, as well as a more recent influx of Asians, especially from Pakistan. The enlargement of the European Union in 2004 led to a dramatic increase in immigration from the countries of eastern Europe.
