As we have already said, the materials for the internal history of the Highlands during the Roman occupation are of the scantiest, nearly all that can be recorded being the struggles of the northern tribes with the Roman invaders, and the incursions of the former and their allies into the territories of the Romanized Britons. Doubtless many events as worthy of record as these, an account of which has been preserved, were during this period being transacted in the northern part of Scotland, and we have seen that many additions, from various quarters, must have been made to the population. However, there are no records extant which enable us to form any distinct notion of the nature of these events, and history cannot be manufactured.

After the departure of the Romans, the provincial Britons of the south of Scotland were completely at the mercy of the Picts as well as the Saxons, who had been invited over by the South Britons to assist them against the northern barbarians. These Saxons, we know, very soon entered into alliance with those whom they came to repel, and between them the Britons south of the friths were eventually driven into the West, where for centuries they appear to have maintained an independent kingdom under the name of Strathclyde, until ultimately they were incorporated with the Scots.[79]

Although both the external and internal history of the Highlands during this period is much better known than in the case of the Roman period, still the materials are exceedingly scanty. Scottish historians, from Fordun and Boece downwards, made it their business to fill up from their own imaginations what is wanting, so that, until the simple-minded but acute Innes put it in its true light, the early history of Scotland was a mass of fable.

Undoubtedly the two most momentous events of this period are the firm settlement in Argyle of a colony of Scots from Ireland and some of the neighbouring isles in 503,[80] and the conversion of the Northern Picts to Christianity by Columba about 563.

At the time of the Roman abandonment of Britain the Picts were under the sway of a king or chieftain named Drust, son of Erp, concerning whom the only record remaining is, that he lived a hundred years and fought a hundred battles. In fact, little is known with certainty of the Pictish history for upwards of one hundred years after the departure of the Romans, although some ancient chronicles afford us lists of Pictish kings or princes, a chronological table of whom, from Drust downwards, will be found at the end of this chapter. The Pictish chronicle contains the names of thirty-six others who are said to have reigned before Drust, but these are generally regarded as almost entirely spurious.

Before proceeding farther with the Pictish history, it may be proper to give a brief account of the settlement of the Irish Scots or Dalriads, as they are frequently called, in the Pictish territory.

The time of the settlement of the Scots in present Scotland was for long a subject of disputation, the early Scottish historians, from a false and unscrupulous patriotism, having pushed it back for many centuries before its actual occurrence. This dispute is now, however, fairly set at rest, there being no foundation for believing that the Scots found their way from Ireland to Scotland earlier than a century or two before the birth of Christ. As we have already seen, we find the first mention of the Scots in Ammianus Marcellinus about the year 360 A.D.; and their name occurs in the same connection frequently afterwards, during the Roman occupation of Scotland. Burton[81] is of opinion that the migration did not take place at any particular time or under any particular leader, but that it was gradual, that the Scots “oozed” out of Ireland upon the western coast of Scotland.

It belongs to the history of Ireland to trace the origin and fix the race of the Scots, to settle the time of their coming into Ireland, and discover whence they came. Some suppose that they migrated originally from Britain to Ireland, while Innes and others bring them either from Scandinavia or Spain, and connect them with the Scyths, asserting that Scot is a mere corruption of Scyth, and dating the settlement at about the commencement of the Christian era. The Irish traditions connect them with a certain Scota, daughter of Pharaoh, and date their coming to Ireland upwards of 1,000 years B.C. E. W. Robertson[82] and others consider them to have been Irish Picts or Cruithne.

Wherever the Scots came from and to whatever race they belong, whether Teutonic or Celtic, they certainly appear not to have been the first settlers in Ireland, and at the time at which they first appear in authentic history occupied a district in Ireland corresponding to Connaught, Leinster, and part of Munster. They were also one of the most powerful of the Irish tribes, seeing that for many centuries Ireland was, after them, called Scotia or Scotland. It is usually said that a particular corner in the north-east of Ireland, about 30 miles in extent, corresponding to the modern county of Antrim, was the kingdom of the particular band of Scots who migrated to Scotland; and that it received its name, Dal-Riada (‘the portion of Riada’), from Carbre-Riada, a leader of the Scots who conquered this particular part, previously inhabited by Cruithne or Irish Picts. Robertson,[83] however, considers all this fable and the kingdom of Dalriada as mythical, Tighernach and the early Irish annalists never applying the name to any other locality than British Dalriada. At all events, this particular district was spoken of by the later chroniclers under the name of Dalriada, there being thus a Dalriada both in Scotland and Ireland.[84] At the time of the migration of the Scots from Ireland to Scotland, they were to all intents and purposes a Celtic race, speaking Trish Gaelic, and had already been converted to Christianity.
