In school you're always taught that the Romans never settled there and built Hadrians wall, but recently i've discovered that this is untrue with settlements North of Dundee and Perth. So my question's are:
What were the settlements like?
Were these Pre- or Post- wall?
To what extent were the indigenous population of Scotland controlled by Rome?
many thanks
The book you want to look into is Agricola by Tacitus about Roman Governor of Brittania Gnaeus Julius Agricola (though take this with a grain of salt because Tacitus was his son-in-law). He invaded Caledonia (Scotland) looking to conquer the whole territory. He invaded basically all the way north to the edge of Scotland. He was doing quite well until he was recalled by Domitian. There is archaeological evidence of Roman forts near Inverness in the Highlands of Scotland.
These settlements were before the walls were made. There are three main Scottish walls: Hadrian's Wall, the Antonine Wall, and the Severan Wall. All were built after Agricola's invasion and his base encampments.
The Romans did a generally good job at defeating the native Caledonians. Roman incursions usually forced the Caledonians to retreat into the Highlands, where the Roman invasions stopped for various reasons (e.g. Agricola being recalled, Caracalla giving up Severus's invasion).
