Stuart or Stewart, David, duke of Rothesay (rŏthˈsē) [key], 1378?–1402, Scottish prince; son and heir apparent of Robert III. On his father's accession (1390) to the throne, David became earl of Carrick and in 1398 duke of Rothesay. In 1399 he was made lieutenant of the kingdom by his invalid father and given sovereign powers for a three-year term, thus displacing the regency of his uncle Robert Stuart, 1st duke of Albany. In 1402, at the end of Rothesay's tenure of office, Albany and Archibald Douglas, 4th earl of Douglas, had him arrested and imprisoned. He died, under questionable circumstances, in their custody.
