The history of Scotland in the High Middle Ages covers Scotland in the era between the death of Domnall II in 900 AD and the death of king Alexander III in 1286, which led indirectly to the Scottish Wars of Independence.
In the tenth and eleventh centuries, northern Great Britain was increasingly dominated by Gaelic culture, and by a Gaelic regal lordship known in Gaelic as "Alba", in Latin as either "Albania" or "Scotia", and in English as "Scotland". From a base in eastern Scotland north of the River Forth, the kingdom acquired control of the lands lying to the south. It had a flourishing culture, comprising part of the larger Gaelic-speaking world.
After the twelfth-century reign of King David I, the Scottish monarchs are better described as Scoto-Norman than Gaelic, preferring French culture to native Scottish culture. They fostered and attached themselves to a kind of Scottish "Norman Conquest". The consequence was the spread of French institutions and social values. Moreover, the first towns, called burghs, began in the same era, and as these burghs spread, so did the Middle English language. To a certain degree these developments were offset by the acquisition of the Norse-Gaelic west, and the Gaelicization of many of the great families of French and Anglo-French origin, so that the period closes with what has been called a "Gaelic revival", and an integrated Scottish national identity. Although there remained a great deal of continuity with the past, by 1286 these economic, institutional, cultural, religious and legal developments had brought Scotland closer to its neighbours in England and the Continent. By 1286 the Kingdom of Scotland had political boundaries that closely resemble those of modern Scotland.
