The First Part of King Henry the Sixth is history play by William Shakespeare, believed written in approximately 1588–1590. It is the first in the cycle of four plays often referred to as "The First Tetralogy". 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. Henry the Sixth, Part 3, is a history play by William Shakespeare, believed written in approximately 1590, and set during the lifetime of King Henry VI of England. It prepares the ground for one of his best-known and most controversial plays: the tragedy of King Richard III (Richard III of England). It continues the action from Henry VI, Part 1 and Henry VI, Part 2, though they may not have been written in that order.
