The Second Part of King Henry the Sixth, or Henry VI, Part 2, is a history play by William Shakespeare believed written in approximately 1590-91. It is the second part of the trilogy on Henry VI, and often grouped together with Richard III as a tetralogy on The Wars of the Roses-the success of which established Shakespeare's reputation as a playwright.
Against the wishes of the nobles, King Henry marries the penniless Margaret who plots against him with her lover. As tensions between York and Lancaster build, the Duke of York gathers supporters for his claim to the throne. York secretly leads a rebellion, his supporters proclaim him king, and Henry is forced to flee.
