Scotland in the Middle Ages concerns the history of Scotland from the departure of the Romans to the adoption of major aspects of the Renaissance in the early sixteenth century. From the fifth century northern Britain was divided into a series of kingdoms. Of these the four most important to emerge were the Picts, the Gaels of Dál Riata, the Britons of Strathclyde and the Anglo-Saxon kingdom of Bernicia, later taken over by Northumbria. After the arrival of the Vikings in the late eighth century, Scandinavian rulers and colonies were established along parts of the coasts and in the islands. In the ninth century the Scots and Picts combined under the House of Alpin to form a single Kingdom of Alba, with a Pictish base and dominated by Gaelic culture. After the reign of King David I in the twelfth century, the Scottish monarchs are best described as Scoto-Norman, preferring French culture to native Scottish culture. Alexander II and his son Alexander III, were able to regain the remainder of the western seaboard, cumulating the Treaty of Perth with Norway in 1266. After being invaded and briefly occupied, Scotland re-established its independence from England under figures including William Wallace in the late thirteenth century and Robert Bruce in the fourteenth century. In the fifteenth century under the Stewart Dynasty, despite a turbulent political history, the crown gained greater political control at the expense of independent lords and regained most of its lost territory to approximately the modern borders of the country. However, the Auld Alliance with France led to the heavy defeat of a Scottish army at the Battle of Flodden in 1513 and the death of the king James IV, which would be followed by a long minority and a period of political instability. Kingship was the major form of government, growing in sophistication in the late Middle Ages. The scale and nature of war also changed, with larger armies, naval forces and the development of artillery and fortifications. The Church in Scotland always accepted papal authority (contrary to the implications of Celtic Christianity), introduced monasticism, and from the eleventh century embraced monastic reform, developing a flourishing religious culture that asserted its independence from English control. Scotland grew from its base in the eastern Lowlands, to approximately its modern borders. The varied and dramatic geography of the land provided a protection against invasion, but limited central control. It also defined the largely pastoral economy, with the first burghs being created from the twelfth century. The population may have grown to a peak of a million before the arrival of the Black Death in 1350. In the early Middle Ages society was divided between a small aristocracy and larger numbers of freemen and slaves. Serfdom disappeared in the fourteenth century and there was a growth of new social groups. The Pictish and Cumbric languages were replaced by Gaelic, Scots and later Norse, with Gaelic emerging as the major cultural language. From the eleventh century French was adopted in the court and in the late Middle Ages, Scots, derived from Old English, became dominant, with Gaelic largely confined to the Highlands. Christianity brought Latin, written culture and monasteries as centres of learning. From the twelfth century, educational opportunities widened and a growth of lay education cumulated in the Education Act 1496. Until in the fifteenth century, when Scotland gained three universities, Scots pursuing higher education had to travel to England or the continent, where some gained an international reputation. Literature survives in all the major languages present in the early Middle Ages, with Scots emerging as a major literary language from John Barbour's Brus (1375), developing a culture of poetry by court makars, and later major works of prose. Art from the early Middle Ages survives in carving, in metalwork, and elaborate illuminated books, which contributed to the development of the wider insular style. Much of the finest later work has not survived, but there are a few key examples, particularly of work commissioned in the Netherlands. Scotland had a musical tradition, with secular music composed and performed by bards and from the thirteenth century, church music increasingly influenced by continental and English forms.
