Kenneth II, d. 995, Scottish king (971–995). The son of Malcolm I (reigned 943–54), he became king of the united Picts and Scots in 971 and immediately led a savage raid on the British in Northumbria. He is later listed, however, as submitting to the Anglo-Saxon king Edgar c.973 and being granted by him the land between the Tweed and Forth rivers. This is the earliest mention of the Tweed as the border between England and Scotland. Kenneth's reign also saw consolidation of his kingdom in the central area north of the Tay River. He was murdered as a result of a conflict with the mormaor (high steward) of Argyll.
