David Stewart, Duke of Rothesay

David Stewart was the son of king Robert III of Scotland and of his wife, Annabella Drummond. Due to his father's sickness, David became "Lieutenant" of the kingdom in 1399, a time of civil unrest and conflict with the neighboring England. His major domestic enemy, his uncle, the experienced Robert Stewart, 1st Duke of Albany, had served as protector of the kingdom until then. Albany arrested David and put him in prison. He died in 1402, in uncertain circumstances, probably by order of Albany himself. Legend says that he starved to death.

David married Marjorie Douglas, daughter of Archibald the Grim, Earl of Douglas, but had no children. In 1406 David's younger brother James Stewart succeeded Robert III on the throne.
