Was Malcolm the first king of Scotland?

First King of Scots (not Scotland) was Kenneth MacAlpine. He is traditionally considered first "King of Scots", or of "Picts and Scots", allegedly having conquered the Picts as a Gael, which is turning history back to front, as most modern scholars point out, he was actually 'King of Picts', and the terms 'King of Alba' and the even later 'King of Scots' were not used until several generations after him.
