Edward III (play)

The Raigne of King Edward the Third, often shortened to Edward III, is an Elizabethan play printed anonymously in 1596, believed to have been partly written by William Shakespeare, its inclusion in publications of the complete works of Shakespeare dating only to the late 1990s. Scholars supporting this attribution include Jonathan Bate, Edward Capell, Eliot Slater, Eric Sams, Giorgio Melchiori and Brian Vickers. The play's co-author remains the subject of debate and speculation; suggestions have included Thomas Kyd, Christopher Marlowe, Michael Drayton, Thomas Nashe and George Peele.

The play contains several gibes at Scotland and the Scottish people, which has led some critics to suggest that it incited George Nicholson, Queen Elizabeth's agent in Edinburgh, to protest against its 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, published after the Scottish King James had succeeded to the English throne in 1603.

The play also contains an explicit reference to its having been produced not only for the stage, but also for the page. In the final sequence, the Black Prince states: "So that hereafter ages, when they read / The painful traffic of my tender youth, / Might thereby be inflamed" (scene 18).
