Other writers are vaguer, whereas Dio Cassius divides non-Roman Britain between the Caledonii and Maeatae.

Agricola defeated the Caledonii at Mons Graupius (Bennachie?) in AD 84, but without conquering them decisively. After the construction of Hadrian's Wall (Tyne-Solway) and Antonine Wall (Forth-Clyde, later abandoned), Septimius Severus renewed the attack on them (209–11), but again without lasting results, though tenuously dependent client kingdoms were later established in Dumbarton and Lothian. The Picts, a people, apparently, of mixed Celtic and non-Celtic race (though the Romans used the name inexactly), are first heard of c 297, and became a serious threat in the fourth century, when, based on Strathmore, they began to control much of central and eastern Scotland; while at the same time immigrants from Ireland not only occupied the maritime regions of Britain from south Wales to the Solway Firth, but planted colonies on the coasts of Argyllshire which developed c 500–50 into principalities, later unified to form Dalriada (the name of their homeland Ulster), in which St. Columba founded his monastery at Iona c 563. These settlers were known as Scotti, and became so numerous and powerful that they gave their name to the whole country.
