Richard III is an early history play probably written and performed around 1592-93. It is the culmination of Shakespeare's earlier three plays about Henry VI, and chronicles the bloody career of Richard, Duke of Gloucester. As the play opens, the Wars of the Roses are over, King Edward IV (Richard's brother) is on the throne, and all is ostensibly well. The problem? Richard wants to be king - and he'll stop at nothing to realize his ambition. (Summary by Elizabeth Klett)
