David V of Scotland (November 18 1803 - June 22 1866) was the third King of Scotland of the Mackintosh line, with a reign lasting from the death of his father David IV in 1842 until his own death in 1866. He ruled over a period of both economic growth in the Lowlands due to the Industrial Revolution and internal battles with belligerent and uncooperative Highlanders, reaching its peak during the Sutherland War at the end of the Second Clan Rebellion.
