Scottish national identity is a term referring to the sense of national identity, as embodied in the shared and characteristic culture, languages and traditions, of the Scottish people. Although the various dialects of Gaelic, the Scots language and Scottish English are distinctive, people associate them all together as Scottish with a shared identity, as well as a regional or local identity. Parts of Scotland, like Glasgow, the Outer Hebrides, Orkney, Shetland, the north east of Scotland and the Scottish Borders retain a strong sense of regional identity, alongside the idea of a Scottish national identity. History Pre-Union Early Middle Ages In the early Middle Ages, what is now Scotland was divided between four major ethnic groups and kingdoms. In the east were the Picts, who fell under the leadership of the kings of Fortriu. In the west were the Gaelic (Goidelic)-speaking people of Dál Riata with close links with the island of Ireland, from which they brought with them the name Scots. In the south-west was the British (Brythonic) Kingdom of Strathclyde, often named Alt Clut. Finally there were the 'English', the Angles, a Germanic people who had established a number of kingdoms in Great Britain, including the Kingdom of Bernicia, part of which was in the south-east of modern Scotland. In the late eighth century this situation was transformed by the beginning of ferocious attacks by the Vikings, who eventually settled in Galloway, Orkney, Shetland and the Hebrides. These threats may have speeded a long-term process of gaelicisation of the Pictish kingdoms, which adopted Gaelic language and customs. There was also a merger of the Gaelic and Pictish crowns. When he died as king of the combined kingdom in 900, Domnall II (Donald II) was the first man to be called rí Alban (i.e. King of Alba). High Middle Ages In the High Middle Ages the word "Scot" was only used by Scots to describe themselves to foreigners, amongst whom it was the most common word. They called themselves Albanach or simply Gaidel. Both "Scot" and Gaidel were ethnic terms that connected them to the majority of the inhabitants of Ireland. At the beginning of the thirteenth century, the author of De Situ Albanie noted: "The name Arregathel [Argyll] means margin of the Scots or Irish, because all Scots and Irish are generally called 'Gattheli'." Scotland came to possess a unity which transcended Gaelic, French and Germanic ethnic differences
