Henry Frederick, Prince of Wales KG (19 February 1594 – 6 November 1612), was the eldest son and heir apparent of James VI and I, King of England and Scotland; and his wife Anne of Denmark. His name derives from his grandfathers: Henry Stuart, Lord Darnley; and Frederick II of Denmark. Prince Henry was widely seen as a bright and promising heir to his father's thrones. However, at the age of 18, he predeceased his father when he died of typhoid fever. His younger brother Charles succeeded him as heir apparent to the English, Irish, and Scottish thrones.
