“If, instead of Wainwright's question, we ask 'What were the Picts?', the answer is very simple. They were a nation created by the union of a number of tribes. This union, formed initially as a military alliance against the common enemy, stood the test of time and long outlived the Roman invasion. For the last seventeen centuries the peoples of this union have been known collectively as the Picts, a name first recorded by the Romans. The name itself is a familiar part of the problem: did Picti really mean 'the painted men, or was it simply the Latin form of a long-forgotten native name? Puting this question on one side for the moment, we might refer to the Picts as 'The United Tribes of Caledonia', or UTC for short, a name which tells us just what they really were.”
