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.

William Shakespeare was an English playwright, poet, and actor. He is widely regarded as the greatest writer in the English language and the world's pre-eminent dramatist. He is often called England's national poet and the "Bard of Avon". His extant works, including collaborations, consist of some 39 plays, 154 sonnets, three long narrative poems, and a few other verses, some of uncertain authorship. His plays have been translated into every major living language and are performed more often than those of any other playwright. Shakespeare remains arguably the most influential writer in the English language, and his works continue to be studied and reinterpreted.
