Given the question: Found the following article online, use it to answer the question: What kingdom had a flourishing culture because of an economy dominated by agriculture and trade? The High Middle Ages of Scotland encompass Scotland in the era between the death of Domnall II in 900 AD and the death of King Alexander III in 1286, which was an indirect cause of the Scottish Wars of Independence. At the close of the ninth century, various competing kingdoms occupied the territory of modern Scotland. Scandinavian influence was dominant in the northern and western islands, Brythonic culture in the southwest, the Anglo-Saxon or English Kingdom of Northumbria in the southeast and the Pictish and Gaelic Kingdom of Alba in the east, north of the River Forth. By the tenth and eleventh centuries, northern Great Britain was increasingly dominated by Gaelic culture, and by the Gaelic regal lordship of Alba, known in Latin as either Albania or Scotia, and in English as "Scotland". From its base in the east, this kingdom acquired control of the lands lying to the south and ultimately the west and much of the north.

National cohesion was fostered with the creation of various unique religious and cultural practices. By the end of the period, Scotland experienced a "Gaelic revival", which created an integrated Scottish national identity. By 1286, these economic, institutional, cultural, religious and legal developments had brought Scotland closer to its neighbours in England and the Continent, although outsiders continued to view Scotland as...
