Richard III

Richard III is William Shakespeare's unflattering depiction of the short reign of Richard III of England, believed to have been written in approximately 1591. The play is sometimes classified as a tragedy (as in the earliest quarto); but it more correctly belongs to the histories, as classified in the First Folio. It picks up the story from Henry VI, Part III and concludes the historical series that stretches back to Richard II. After Hamlet it is Shakespeare's second longest play and is the longest of the First Folio, whose version of Hamlet is shorter than the Quarto version. The length is generally seen as a drawback, for which reason it is rarely performed unabridged. It is often shortened by cutting peripheral characters. Another reason for editing is that Shakespeare assumed that his audiences would be familiar with the Henry VI plays, and frequently made indirect references to events in them, such as Richard's murder of Henry VI or the defeat of Henry's queen Margaret.... full article at wikipedia
