Edward of Middleham, also known as Edward Plantagenet (1473 - April 9 1484) was the only son of King Richard III of England and his wife Anne Neville.
In 1478, following the execution of George, Duke of Clarence for treason the title Earl of Salisbury was granted to Edward until his death when the title became extinct. He was also invested as Prince of Wales following his father's succession as king of England in 1483.
Edward's death left his father without an heir, leaving the way open for Henry Tudor to take the throne at the Battle of Bosworth Field in 1485.
