Henry VI, Part 2 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 Henry VI, Part 1 deals primarily with the loss of England's French territories and the political machinations leading up to the Wars of the Roses, and Henry VI, Part 3 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).

In the First Folio, the plays of William Shakespeare were grouped into three categories: comedies, histories, and tragedies. The histories—along with those of contemporary Renaissance playwrights—help define the genre of history plays. The Shakespearean histories are biographies of English kings of the previous four centuries and include the standalones King John, Edward III and Henry VIII as well as a continuous sequence of eight plays. These last are considered to have been composed in two cycles. The so-called first tetralogy, apparently written in the early 1590s, covers the Wars of the Roses saga and includes Henry VI, Parts I, II & III and Richard III. The second tetralogy, finished in 1599 and including Richard II, Henry IV, Parts I & II and Henry V, is frequently called the Henriad after its protagonist Prince Hal, the future Henry V.
