The Kingdom of Scotland also known as the Kingdom of Alba was a kingdom that lasted from 843 CE to 1707 CE.
Origins: 400–943[]
From the 5th century on, north Britain was divided into a series of petty kingdoms. Of these, the four most important were those of the Picts in the north-east, the Scots of Dál Riata in the west, the Britons of Strathclyde in the south-west and the Anglian kingdom of Bernicia (which united with Deira to form Northumbria in 653) in the south-east, stretching into modern northern England. In 793, ferocious Viking raids began on monasteries such as those at Iona and Lindisfarne, creating fear and confusion across the kingdoms of north Britain. Orkney, Shetland and the Western Isles eventually fell to the Norsemen. These threats may have sped up 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 kingdoms, although historians debate whether it was a Pictish takeover of Dál Riata, or vice-versa. This culminated in the rise of Cínaed mac Ailpín (Kenneth MacAlpin) as "king of the Picts" in the 840s (traditionally dated to 843), which brought to power the House of Alpin. When he died as king of the combined kingdom in 900, one of his successors, Domnall II (Donald II), was the first man to be called rí Alban (King of Alba). The term Scotia would increasingly be used to describe the heartland of these kings, north of the River Forth, and eventually the entire area controlled by its kings would be referred to as Scotland. The long reign (900–942/3) of Donald's successor Causantín (Constantine II) is often regarded as the key to formation of the Kingdom of Alba/Scotland, and he was later credited with bringing Scottish Christianity into conformity with the Catholic Church.
Expansion: 943–1513[]
Máel Coluim I (Malcolm I) (r. c. 943–954) is believed to have annexed the Kingdom of Strathclyde, over which the kings of Alba had probably exercised some authority since the later 9th century. His successor, Indulf the Aggressor, was described as the King of Strathclyde before inheriting the throne of Alba; he is credited with later annexing parts of Lothian, including Edinburgh, from the Kingdom of Northumbria. The reign of David I has been characterised as a "Davidian Revolution", in which he introduced a system of feudal land tenure, established the first royal burghs in Scotland and the first recorded Scottish coinage, and continued a process of religious and legal reforms. Until the 13th century, the border with England was very fluid, with Northumbria being annexed to Scotland by David I, but lost under his grandson and successor Malcolm IV in 1157. The Treaty of York (1237) fixed the boundaries with England close to the modern border. By the reign of Alexander III, the Scots had annexed the remainder of the, Norwegian held, western seaboard after the stalemate of the Battle of Largs and the Treaty of Perth in 1266. The Isle of Man fell under English control, from Norwegian, in the 14th century, despite several attempts to seize it for Scotland. The English briefly occupied most of Scotland, under Edward I. Under Edward III, the English backed Edward Balliol, son of King John Balliol, in an attempt to gain his father's throne and restore the lands of the Scottish lords dispossessed by Robert I and his successors in the 14th century in the Wars of Independence (1296–1357). The king of France attempted to thwart the exercise, under the terms of what became known as the Auld Alliance, which provided for mutual aid against the English. In the 15th and early 16th centuries, 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 around the modern borders of the country. The dowry of the Orkney and Shetland Islands, by the Norwegian crown, in 1468 was the last great land acquisition for the kingdom. In 1482 the border fortress of Berwick—the largest port in medieval Scotland—fell to the English once again; this was the last time it changed hands. The Auld Alliance with France led to the heavy defeat of a Scottish army at the Battle of Flodden Field in 1513 and the death of the King James IV. A long period of political instability followed.
