Henry VI, Part 1, often referred to as 1 Henry VI, is a history play by William Shakespeare--possibly in collaboration with Christopher Marlowe and Thomas Nashe--believed to have been written in 1591. It is set during the lifetime of King Henry VI of England.

Whereas Henry VI, Part 2 deals with the King's inability to quell the bickering of his nobles and the inevitability of armed conflict and Henry VI, Part 3 deals with the horrors of that conflict, Henry VI, Part 1 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.

Although the Henry VI trilogy may not have been written in chronological order, the three plays are often grouped together with Richard III to form a tetralogy covering the entire Wars of the Roses saga, from the death of Henry V in 1422 to the rise to power of Henry VII in 1485. It was the success of this sequence of plays that firmly established Shakespeare's reputation as a playwright.

Some regard Henry VI, Part 1 as the weakest of Shakespeare's plays. Along with Titus Andronicus, it is generally considered one of the strongest candidates for evidence that Shakespeare collaborated with other dramatists early in his career.

Henry VI, Part 2 (often written as 2 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 1 Henry VI deals primarily with the loss of England's French territories and the political machinations leading up to the Wars of the Roses, and 3 Henry VI deals with the horrors of that conflict, 2 Henry VI focuses on the King's inability to quell the bickering of his nobles, the death of his trusted adviser Humphrey, Duke of Gloucester, the rise of the Duke of York and the inevitability of armed conflict. As such, the play culminates with the opening battle of the War, the First Battle of St Albans (1455).

Henry VI, Part 2 has the largest cast of all Shakespeare's plays and is seen by many critics as the best of the Henry VI trilogy.

Henry VI, Part 3 (often written as 3 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 1 Henry VI deals with the loss of England's French territories and the political machinations leading up to the Wars of the Roses and 2 Henry VI focuses on the King's inability to quell the bickering of his nobles, and the inevitability of armed conflict, 3 Henry VI deals primarily with the horrors of that conflict, with the once stable nation thrown into chaos and barbarism as families break down and moral codes are subverted in the pursuit of revenge and power.

Henry VI, Part 3 features the longest soliloquy in all of Shakespeare (3.2.124-195) and has more battle scenes (four on stage, one reported) than any other of Shakespeare's plays.
