Horrible Histories is a British children's sketch comedy television series, part of the children's history franchise of the same name based on the books written by Terry Deary.
It maintains the franchise's overall irreverent but accurate focus on the dark, gruesome or scatological aspects of British and other Western world history, spanning from the Stone Age to the post-WWII era. Individual historical eras or civilisations are defined and named as in the books, with sketches from several different time periods combined within a single episode. Live-action sketches—which often parody other UK media or celebrities—and music videos are intercut with animations and quizzes.
