He died on the 10th of March 1792 and was buried at Rothesay in Bute.
The Scottish seaboard is divided for administrative purposes into twenty-seven fishery districts, namely, on the east coast, Eyemouth, Leith, Anstruther, Montrose, Stonehaven, Aberdeen, Peterhead, Fraserburgh, Banff, Buckie, Findhorn, Cromarty, Helmsdale, Lybster, Wick (15); on the north, Orkney, Shetland (2); on the west, Stornoway, Barra, Loch Broom, Loch Carron and Skye, Fort William, Campbeltown, Inverary, Rothesay, Greenock, Ballantrae (10).
The reign of a weakling was full of anarchy, complicated by the feud between his eldest son, the wayward duke of Rothesay, and his ambitious brother, now duke of Albany.
By this parliament, David, prince of Scotland and duke of Rothesay, was made regent for three years; with his uncle, duke of Albany, as his coadjutor.
Peace between Albany and the wayward Rothesay was impossible, and Rothesay, by breaking troth with the daughter of the earl of March, and marrying a daughter of the third earl of Douglas, added a fresh feud to the general confusion.
Rothesay held it in his contempt, and, as Albany declined a battle in the open, Henry returned with nothing gained.

On his eldest son David, who was made duke of Rothesay, and on his brother, who became duke of Albany.
Robert doubtless decided upon this course owing to the fact that in 1402 his elder son, David, duke of Rothesay, had met his death in a mysterious fashion, being probably murdered by his uncle, Robert, duke of Albany, who, as the king was an invalid, was virtually the ruler of Scotland.
