Duncan II of Scotland
Duncan II (c. 1060–1094) was the eldest son of Malcolm III. Handed to William the Conqueror as a hostage in 1072, he grew up a knight at the Norman court. After his uncle Donald III seized the throne in 1093, Duncan invaded with troops lent by William II, won and was crowned at Scone in 1094.
Once he dismissed his foreign soldiers he was ambushed and killed by Donald's men on 12 November 1094, after less than seven months as king.
