The 2 parts had first appeared separately (and anonymously) in 1594 and 1595, under titles "The First part of the Contention betwixt the two famous Houses of Yorke and Lancaster", and "The true Tragedie of Richard Duke of Yorke ..." They form the basis of Shakespeare's Henry VI, pt. 2 and 3. The authorship and their relation to his version are much disputed.
