Henry VI, Part 1 or The First Part of Henry the Sixth (often written as 1 Henry VI) is a history play by William Shakespeare, believed to have been written in 1591, and set during the lifetime of King Henry VI of England. Whereas 2 Henry VI deals with the King's inability to quell the bickering of his nobles, and the inevitability of armed conflict, and 3 Henry VI deals with the horrors of that conflict, 1 Henry VI deals with the loss of England's French territories and the political machinations leading up to the Wars of the Roses, as the English political system is torn apart by personal squabbles and petty jealousy.
