By the 5th century, the Gaelic or "Scottish" kingdom of Dál Riata had emerged in the area of modern Scotland that is now Argyll. Although this kingdom was destroyed and subjugated by the Pictish kingdom of the 8th century under Angus I, the convergence of Pictish and Gaelic languages over several centuries resulted in the English labelling Pictland under Constantine II as "Scottish" in the early 10th century, first attested in AD 920, viewing the Picts as speaking a Gaelic tongue. The growing influence of English language and Scots from the 12th century with the introduction of Anglo-French knights and southerly expansion of Scotland's borders by David I, saw the terms "Scot", "Scottish" and "Scotland" also begin to be used commonly by natives of that country.
