A historical drama (also period drama, costume drama, and period piece) is a work set in a past time period, usually used in the context of film and television. Historical drama includes historical fiction and romances, adventure films, and swashbucklers. A period piece may be set in a vague or general era such as the Middle Ages or a specific period such as the Roaring Twenties.
While historical drama is fiction, works may include references to real-life people or events from the relevant time period or contain factually accurate representations of the time period. Works may also include mostly-fictionalized narratives based on actual people or events, such as Schindler's List, Braveheart, and Les Misérables.
Works that focus on accurately portraying specific historical events or persons are instead known as docudrama (such as The Report). Where a person's life is central to the story, such a work is known as biographical drama (examples being Cinderella Man and Lincoln).
Film and television examples of period pieces include Marie Antoinette (1938), The Leopard (1963), Barry Lyndon (1975), Amadeus (1984), The Age of Innocence (1993), Last Man Standing (1996), Shakespeare in Love (1998), Bathory (2008), The Other Boleyn Girl (2008), The Young Victoria (2009), Darkest Hour (2017), The Favourite (2018), and Little Women (2019).
