David Stewart, Duke of Rothesay, heir to the throne of Scotland (born 1378)

David Stewart was the eldest son of Robert III of Scotland and his wife, Annabella Drummond. The heir apparent to the Scottish throne from 1390 until his death, David held the titles of Prince of Scotland, Duke of Rothesay, and Earl of Carrick. David was named by a general council to rule Scotland as regent, on behalf of his infirm and politically ineffective father, in 1399. He was responsible for the defense of Scotland during the English invasion in 1400. After coming into conflict with his uncle, Robert Stewart, Duke of Albany, David was arrested and removed from power in late 1401. He died in mysterious circumstances at Falkland Palace shortly afterwards. David's younger brother, James, eventually succeeded their father as King of Scots.
