The Raigne of King Edward the Third, commonly shortened to Edward III, is an Elizabethan play printed anonymously in 1596. It has frequently been claimed that it was at least partly written by William Shakespeare, a view that Shakespeare scholars have increasingly endorsed. The rest of the play was probably written by someone else: Thomas Kyd, Christopher Marlowe, Michael Drayton, and George Peele among the top contenders, with recent scholars introducing Thomas Nashe to the fold.
The play contains several gibes at Scotland and the Scottish people, which has led some critics to think that it is the work that incited George Nicolson, Queen Elizabeth's agent in Edinburgh, to protest against the portrayal of Scots on the London stage in a 1598 letter to William Cecil, Lord Burghley. This could explain why the play was not included in the First Folio of Shakespeare's works, which was published after the Scottish King James had succeeded to the English throne in 1603.
