Why did the picts vanish?
the reason they.(VANISHED.)is quite simple the picts handed down power through the female side of the family and kenneth mac alpins mother was princess of picts and his father was king of dalriada scots so in time kenneth became king of both peoples so that in effect they amalgamated and the scots today are a mixture of both these people .
The Picts are the original inhabitants of what became Scotland. The Romans called them the 'Caledonia' or 'Painted Ones'. The Scots were a Celtic tribe from what is now Northern Ireland, the 'Scotti'. The Scotti moved to the Argyle region of Scotland and slowly 'bred out' the Picts. The country eventually became known as Scotland.
You must be inquiring about the Picts. Unfortunately the Picts were very poor record keepers so little is actually known about them except what the Romans and Gaels recorded about them. The Picts eventually merged with the Gaelic Dal Riata kingdom from North Ireland as the latter settled in what is modern day Scotland in the 10th century.
