Aspect of Scottish history
Scotland during the Roman Empire refers to the protohistorical period during which the Roman Empire interacted within the area of modern Scotland. Despite sporadic attempts at conquest and government between the first and fourth centuries AD, most of modern Scotland, inhabited by the Caledonians and the Maeatae, was not incorporated into the Roman Empire with Roman control over the area fluctuating.
In the Roman imperial period, the area of Caledonia lay north of the River Forth, while the area now called England was known as "Britannia", the name also given to the Roman province roughly consisting of modern England and Wales and which replaced the earlier Ancient Greek designation as "Albion". Roman legions arrived in the territory of modern Scotland around AD 71, having conquered the Celtic Britons of southern Britannia over the preceding three decades. Aiming to complete the Roman conquest of Britannia, the Roman armies under Quintus Petillius Cerialis and Gnaeus Julius Agricola campaigned against the Caledonians in the 70s and 80s. The "Agricola", a biography of the Roman governor of Britannia by his son-in-law Tacitus mentions a Roman victory at "Mons Graupius" which became the namesake of the Grampian Mountains but whose identity has been questioned by modern scholarship. In 2023 a lost Roman road built by Julius Agricola was rediscovered in Drip close to Stirling: it has been described as "the most important road in Scottish history".
Agricola then seems to have repeated an earlier Greek circumnavigation of the island by Pytheas and received submission from local tribes, establishing the Roman "limes" of actual control first along the Gask Ridge, and then withdrawing south of a line from the Solway Firth to the River Tyne, i.e. along the Stanegate. This border was later fortified as Hadrian's Wall. Several Roman commanders attempted to fully conquer lands north of this line, including a second-century expansion that was fortified as the Antonine Wall.
The history of the period is complex and not well-documented. The province of Valentia, for instance, may have been the lands between the two Roman walls, or the territory around and south of Hadrian's Wall, or Roman Wales. Romans held most of their Caledonian territory only a little over 40 years; they probably only held land in present-day Scotland for about 80 years. Some Scottish historians such as Alistair Moffat maintain Roman influence was inconsequential. Despite grandiose claims made by an eighteenth-century forged manuscript, it is now believed that the Romans at no point controlled even half of present-day Scotland and that Roman legions ceased to affect the area after around 211.
"Scots" and "Scotland" proper would not emerge as unified ideas until the eighth century. In fact, the Roman Empire influenced every part of Scotland during the period: by the time of the End of Roman rule in Britannia around 410, the various Iron Age tribes native to the area had united as, or fallen under the control of, the Picts, while the southern half of the country was overrun by tribes of Romanized Britons. The Scoti (Gaelic Irish raiders who would give Scotland its Anglicised name) had begun to settle along the west coast. All three groups may have been involved in the Great Conspiracy that overran Roman Britannia in 367. The era saw the emergence of the earliest historical accounts of the natives. The most enduring legacies of Rome, however, were Christianity and literacy, both of which arrived indirectly via Irish missionaries. 
Iron Age culture in Scotland.
Ptolemy's tribes located north of the Forth-Clyde isthmus include the Cornovii in Caithness, the Caereni, Smertae, Carnonacae, Decantae, Lugi, and Creones also north of the Great Glen, the Taexali in the north-east, the Epidii in Argyll, the Venicones in Fife, the Caledonians in the central Highlands and the Vacomagi centred near Strathmore. It is likely that all of these cultures spoke a form of Celtic language known as Common Brittonic. The occupants of southern Scotland were the Damnonii in the Clyde valley, the Novantae in Galloway, the Selgovae on the south coast and the Votadini to the east. These peoples may have spoken a form of Brittonic language although no one really knows for sure as there are no written records.
Little is known about this alliance of Iron Age tribes. The exact location of "Caledonia" is unknown, and the boundaries are unlikely to have been fixed. The name itself is a Roman one, as used by Tacitus, Ptolemy, Pliny the Elder and Lucan, but the name by which the Caledonians referred to themselves is unknown. It is likely that prior to the Roman invasions, political control in the region was highly decentralised and no evidence has emerged of any specific Caledonian military or political leadership.
Despite the discovery of many hundreds of Iron Age sites in Scotland, there is still a great deal that remains to be explained about the nature of the Celtic life in the early Christian era. Radiocarbon dating for this period is problematic and chronological sequences are poorly understood. For a variety of reasons, much of the archaeological work to date in Scotland has concentrated on the islands of the west and north and both excavations and analysis of societal structures on the mainland are more limited in scope.
The peoples of early Iron Age Scotland, particularly in the north and west, lived in substantial stone buildings called Atlantic roundhouses. The remains of hundreds of these houses exist throughout the country, some merely piles of rubble, others with impressive towers and outbuildings. They date from about 800 BC to AD 300, with the most imposing structures having been created around the second century BC. The most massive constructions that date from this time are the circular brochs. On average, the ruins only survive up to a few metres above ground level, but there are five extant examples of towers whose walls still exceed in height. There are at least 100 broch sites in Scotland. Despite extensive research, their purpose and the nature of the societies that created them are still a matter of debate.
In some parts of Iron Age Scotland, quite unlike almost all of recorded history right up to the present day, there does not seem to have been a hierarchical elite. Studies have shown that these stone roundhouses, with massively thick walls, must have contained virtually the entire population of islands such as Barra and North Uist. Iron Age settlement patterns in Scotland are not homogeneous, but, in these places, there is no sign of a privileged class living in large castles or forts, nor of an elite priestly caste or of peasants with no access to the kind of accommodation enjoyed by the middle classes.
Over 400 souterrains have been discovered in Scotland, many of them in the south-east, and, although few have been dated, those that have suggest a construction date in the second or third centuries. The purpose of these small underground structures is also obscure. They are usually found close to settlements (whose timber frames are much less well-preserved) and may have been for storing perishable agricultural products.
Scotland also has numerous vitrified forts but an accurate chronology has again proven to be evasive. Extensive studies of such a fort at Finavon Hill near Forfar in Angus, using a variety of techniques, suggest dates for the destruction of the site in either the last two centuries BC or the mid-first millennium. The lack of Roman artefacts (common in local souterrain sites) suggests that many sites were abandoned before the arrival of the legions.
Unlike the earlier Neolithic and Bronze Ages, which have provided massive monuments to the dead, Iron Age burial sites in Scotland are rare, and a 2008 find at Dunbar may provide further insight into the culture of this period. A similar site of a warrior's grave at Alloa has been provisionally dated to AD 90–130.
Settlements and southern brochs.
Ptolemy's "Geography" identifies 19 "towns" from intelligence gathered during the Agricolan campaigns of the first century. No archaeological evidence of any truly urban places has been found from this time and the names may have indicated hill forts or temporary market and meeting places. Most of the names are obscure: "Devana" may be the modern Banchory; "Alauna" ("the rock") in the west is probably Dumbarton Rock and the place of the same name in the east Lowlands may be the site of Edinburgh Castle. "Lindon" may be Balloch on Loch Lomond side.
There are remains of fifteen broch towers in southern Scotland that appear to date from the period immediately prior to or following Agricola's invasion. They are found in four locations: the Forth valley, close to the Firth of Tay, the far south-west and the eastern Borders. Their existence so far from the main centres of broch-building is something of a mystery. The Leckie broch may have been destroyed by the Roman invaders, yet, like the nearby site of Fairy Knowe at Buchlyvie, a substantial amount of both Roman and native artefacts has been recovered there. Both structures were built in the late first century and were evidently high-status buildings. The inhabitants raised sheep, cattle and pigs, and benefited from a range of wild game, including red deer and wild boar.
Edin's Hall Broch in Berwickshire is the best-preserved southern broch and, although the ruins are superficially similar to some of the larger Orcadian broch villages, it is unlikely that the tower was ever more than a single-storey high. There is an absence of Roman artefacts at this site. Various theories for the existence of these structures have been proposed, including their construction by northern invaders following the withdrawal of Roman troops after the Agricolan advance, or by allies of Rome encouraged to emulate the impressive northern style in order to suppress native resistance, perhaps even the Orcadian chiefs whose positive relationship with Rome may have continued from the beginnings of Romano-British relations. It is also possible that their construction had little to do with Roman frontier policy and was simply the importation of a new style by southern elites, or it may have been a response by such elites to the growing threat of Rome prior to the invasion and an attempt to ally themselves, actually or symbolically, with the north that was largely free of Roman hegemony.
Roman geography.
Scotland had been inhabited for thousands of years before the Romans arrived. However, it is only during the Greco-Roman period that Scotland is recorded in writing.
The work "On the Cosmos" by Aristotle or Pseudo-Aristotle mentions two "very large" islands called Albion (Great Britain) and Ierne (Ireland). The Greek explorer and geographer Pytheas visited Britain sometime between 322 and 285 BC and may have circumnavigated the mainland, which he describes as being triangular in shape. In his work "On the Ocean", he refers to the most northerly point as "" (Orkney).
Originals of "On the Ocean" do not survive, but copies are known to have existed in the first century so at the least a rudimentary knowledge of the geography of north Britain would have been available to Roman military intelligence. Pomponius Mela, the Roman geographer, recorded in his "De Chorographia", written around AD 43, that there were 30 Orkney islands and seven "Haemodae" (possibly Shetland). There is certainly evidence of an Orcadian connection with Rome prior to AD 60 from pottery found at the Broch of Gurness. By the time of Pliny the Elder (d. AD 79), Roman knowledge of the geography of Scotland had extended to the "Hebudes" (The Hebrides), "Dumna" (probably the Outer Hebrides), the Caledonian Forest, and the Caledonians. A traveller called Demetrius of Tarsus related to Plutarch the tale of an expedition to the west coast in or shortly before AD 83. He stated that it was "a gloomy journey amongst uninhabited islands" but that he had visited one which was the retreat of holy men. He mentioned neither the druids nor the name of the island. Ptolemy, possibly drawing on earlier sources of information as well as more contemporary accounts from the Agricolan invasion, identified 18 tribes in Scotland in his "Geography", but many of the names are obscure. His information becomes much less reliable in the north and west, suggesting early Roman knowledge of these areas were confined to observations from the sea. Famously, his co-ordinates place most of Scotland north of Hadrian's Wall bent at a right angle, stretching due eastward from the rest of Britain.
Ptolemy's catalogue of tribes living north of the Forth-Clyde isthmus include the Caereni, Smertae,
