In the First Folio, the plays of William Shakespeare were grouped into three categories: comedies, histories, and tragedies; and modern scholars recognise a fourth category, romance, to describe the specific types of comedy that appear in Shakespeare's later works.
In the First Folio (1623), the plays of William Shakespeare were in three categories: (i) comedies, (ii) histories, and (iii) tragedies. Alongside the history plays of his Renaissance playwright contemporaries, the histories of Shakespeare define the theatrical genre of history plays. The historical plays also are biographies of the English kings of the previous four centuries, and include the plays King John, Edward III, and Henry VIII, and a continual sequence of eight plays known as the Henriad, for the protagonist Prince Hal, the future King Henry V of England.
The chronology of Shakespeare's plays indicates that the first tetralogy was written in the early 1590s, and discusses the politics of the Wars of the Roses; the four plays are Henry VI, parts I, II, and III, and The Tragedy of Richard the Third. The second tetralogy was completed in 1599, and comprises the history plays Richard II, Henry IV, parts I and II, and Henry V.
Shakespearean tragedy is the designation given to most tragedies written by William Shakespeare. Many of his history plays share the qualifiers of a Shakespearean tragedy, but because they are based on real figures throughout the history of England, they were classified as "histories" in the First Folio. The Roman tragedies—Julius Caesar, Antony and Cleopatra and Coriolanus—are also based on historical figures, but because their sources were foreign and ancient, they are almost always classified as tragedies rather than histories. Shakespeare's romances (tragicomic plays) were written late in his career and published originally as either tragedy or comedy. They share some elements of tragedy, insofar as they feature a high-status central character, but they end happily like Shakespearean comedies. Almost three centuries after Shakespeare's death, English scholar Frederick S. Boas also coined a fifth category, the "problem play," for plays that do not fit neatly into a single classification because of their subject matter, setting, or ending. Scholars continue to disagree on how to categorize some Shakespearean plays.
