They came, they saw, but did they conquer? That’s the first question on many peoples’ minds when considering Rome’s efforts to subdue Scotland. Pseudo-histories and long-busted myths still endure in the popular imagination, while even Scotland’s foremost historians and archaeologists debate the extent and nature of Rome’s brief but dramatic presence north of Hadrian’s Wall.
Leading on from last month’s summary of the history of Scottish castles, I’m here to put all our legionaries in a row when it comes to the fundamentals. When did they arrive? Why did they leave? Did Scotland truly remain unconquered by them? Read on for a crash course in the Roman invasions of Scotland. The first coordinated incursion into what is now Scotland occurred in 78 or 79AD under the Governor of Britannia, Gnaeus Julius Agricola, though scouting parties no doubt ranged north for several years before then. As far back as Emperor Claudius’ invasion of Britannia in 43AD, Roman navies circumnavigated the British mainland and reached even allegedly received submission from the king of Orkney.
The reach of Rome

Fresh from annihilating local druidic resistance in Wales, Agricola proceeded into southern Scotland to extend the reach of Rome to the limits of the known world. Beyond Britannia was, they believed, ultima thule, the most distant point on earth. If Rome could conquer Britannia, nowhere on earth would be beyond its grasp.
The campaign of the late 70s and early 80sAD saw the only large-scale pitched battle yet known between Romans and Caledonians. According to Tacitus, Agricola’s son-in-law and biographer, it occurred at a place called Mons Graupius, the Graupian Mountain. A transcription error in the 15th century led to the Graupians being spelled to this day as the Grampians. This is the battle that gave us the Caledonian chieftain Calgacus’ epic speech extolling the “last of the free” to defend their homeland against Roman tyranny – though Calgacus was almost certainly invented by Tacitus to give Agricola a worthy, named adversary.
No one knows precisely where this battle was fought, but Tacitus records that some 10,000 Caledonians were slain while fewer than 300 Roman auxiliaries fell. Propaganda aside, the Highland tribes were scattered but not wholly defeated. Their time for revenge would come. Meanwhile, Agricola fought an insurgency and never again managed to lure the locals into a pitched battle. Southern Scotland as far as the Tay had been secured for Rome and the tribes to the north had been cowed, but not for long.
The Antonine Wall

By 90AD all Roman forts north of the Forth-Clyde line were abandoned, as too were some major forts further south. Evidence from several forts show signs of burning, though whether this was done by Romans wishing to deny local tribes any spoiled or by the tribes themselves in anger, no one yet knows for sure. The legions returned within a few years though made no major progress until the late 130s and early 140s AD when the Antonine Wall was built, stretching from Bo’ness on the Forth to Old Kilpatrick on the Clyde.
The Antonine Wall was a major undertaking, comprising 17 forts with a total garrison of some 7,000 legionaries and auxiliaries. Significant remains can still be seen at Rough Castle in Falkirk, Croy Hill, and the bathhouse at Bearsden. It was occupied for only 20 years before the Romans had to withdraw south once more, though not before they dealt some devastating blows to the locals. A massive assault was orchestrated on the native hillfort of Burnswark near Lockerbie, with stone and bolt-throwing siege engines, massed slingers and archers, and thousands of legionaries arrayed against the Selgovae tribe on the hilltop. None were spared, a terrible lesson in the price of defying Rome’s ambitions.

Another campaign was mounted in the 180s under the Emperor Commodus, though by the end of that decade many Roman forts from the Tay to the Tweed were again burnt – this time, almost certainly by native hands hoping to drive the invaders out forever. The final confirmed campaign of any scale came with the Emperor Septimius Severus and his sons, Caracalla and Geta, in 208-211AD. Severus gave Caracalla explicit orders to annihilate men, women, children, and animals alike, and archaeological evidence bears out that these orders were followed with ruthless comprehensiveness. However, Severus’ death in York in 211 halted the campaign, and Hadrian’s Wall once again became Rome’s northernmost frontier in Britannia.
A possible campaign was mounted in the early 4th century, but no conclusive evidence for this has yet been found. So, far from never invading Scotland or making much progress in it, Rome mounted at least five major periods of campaigning which brought imperial troops as far north as the Moray Firth near Inverness. For those who believe that Rome under-invested in its northern invasions, in the late 2nd century AD 1 in 5 Roman soldiers in the entire empire were stationed in northern Britannia.
Military occupation

Their reasons for withdrawing are hotly debated to this day. Rome extracted raw materials from Scotland as well as countless enslaved people, but the area’s riches were nothing like the silver veins of Iberia or the spice and salt roads of the eastern Mediterranean. Some argue that the Caledonians were simply too ferocious for the Romans, or that the Highland topography proved too challenging. Yet, Rome conquered equally warlike peoples in Germania, the Balkans, Cappadocia, and elsewhere, and met with even more challenging terrain in the form of the Pyrenees, North African deserts, and indeed among the Alpine Gauls in northern Italy.
There is simply no single answer or cause for why Rome failed to conquer Scotland, just as there is no single answer for why modern empires such as the United States or Soviet Union failed to conquer Afghanistan. The Roman occupation of Scotland was intended to be permanent, with Roman towns and the locals converted to Roman ways, but in the end it amounted to purely military occupation. There were no civitas (towns), grand villas, or civic infrastructure projects like aqueducts – only forts, marching camps, roads to facilitate the movement of troops, and defensive lines in the proverbial sand such as the Antonine Wall and Gask Ridge system west of Perth. Tribes who revolted against the Romans or who merely got in the way of conquest were subjected to brutal punitive campaigns and massacres.
The military nature of the occupation left little love lost between natives and invaders. Only a handful of dragonesque brooches, hallmarks of Romano-British culture, survive in the southeast at locations like Trimontium, one of the hubs of the invasion effort. In southern Scotland there are only the merest hints of anything resembling the entrenched Romano-British culture which emerged further south.
The blink of an eye

Locals in what is now the Scottish Borders, Lothians, and Dumfries and Galloway certainly traded with the Romans, while some tribes accepted bribes meant to keep them out of the way. The most famous example is the Traprain Treasure, a hoard of Roman silver hacked up and given to the Votadini tribe whose capital was atop the whaleback hill of Traprain Law in East Lothian.
The story of the Roman invasions of Scotland has captured imaginations for centuries despite only occurring for what is, in historical terms, the blink of an eye – around 140 years from first incursion to the final withdrawal. Increasingly, more scholarly and popular light is being shone not on the invaders, but on the native peoples who resisted them and who lived their lives with the shadow of the Empire looming over them.
This is the focus of the work being done by organisations including the Trimontium Trust in the Scottish Borders and the Scottish Crannog Centre in Perthshire. Both have many fantastic online resources where you can continue your journey of understanding the legacy of the Roman invasions of Scotland, and how – albeit for a brief time – they contributed to the Scotland we know today.
