Henry Vi Part Three

"Henry VI, Part 3 is dominated by a struggle between two military forces, neither of which can achieve victory for long. Until the end, the Yorkists and Lancastrians strive for the English crown. The conflict between these two families began under Richard II. Half a century later, during the reign of Henry VI, it moved toward civil war. Now, in Henry VI, Part 3, Henry’s long reign becomes intermittent as his cousin Richard, Duke of York, seeks the crown and York’s son Edward sporadically succeeds in seizing it." --
