This tragedy was first printed in its present form, in the folio of 1623. It is an enlarged and improved version by Shakespeare, of “The True Tragedie of Richard, Duke of Yorke,” &c. before adverted to, as that, we conceive, was an alteration and improvement by him of an earlier drama, the work of one or more of his contemporaries.

From the circumstance of Robert Greene's paraphrasing a line of “The True Tragedy :”—

when reflecting on Shakespeare, in his “Groatsworth of Wit,” 1592, and of some resemblances between passages in his acknowledged dramas and passages in “The True Tragedy,” it may be inferred that he had some share in the production of the piece or pieces, on which were based “The First Part of the Contention,” and “The True Tragedie of Richard, Duke of Yorke.” This deduction is strengthened by a passage in “Greene's Funeralls, By R. B. Gent.” 4to. Lond. 1594, a small tract of twelve leaves preserved in the Bodleian Library :—
