Generally speaking, Richard III carries on the theme of guilt and retribution that in one way or another links eight of Shakespeare’s history plays, and concludes the series with the theme of order restored. Motivated by a totally unconscionable ambition for power, the protagonist intensifies the bloody disorder which has plagued England since the deposition of Richard II until he becomes subject to retribution himself at the hands of Richmond, whose success at Bosworth Field is the prelude to peace and unity in England. The deposition of Richard II had led to a division between the houses of York and Lancaster, and this division was responsible for the moral chaos that afflicted England during the Wars of the Roses. When, in Richard II, Carlyle protests against the deposition and prophesies its effect—

-he is, in effect, partially echoing or anticipating Richmond's choric statement at the end of Richard III that the marriage of himself and Elizabeth, 'the true succeeders of each royal house', would bring an end to the unnatural division of brother and brother, and father and son. 'The fair conjunction' of 'the white rose and the red' would, he asserted, unify all that 'divided York and Lancaster, / Divided in their dire division' (v, v, 19, 20, 27-8).
