Alice is a fictional character and the main protagonist of Lewis Carroll's children's novel Alice's Adventures in Wonderland (1865) and its sequel, Through the Looking-Glass (1871). A child in the mid-Victorian era, Alice unintentionally goes on an underground adventure after accidentally falling down a rabbit hole into Wonderland; in the sequel, she steps through a mirror into an alternative world. The character originated in stories told by Carroll to entertain the Liddell sisters while rowing on the Isis with his friend Robinson Duckworth, and on subsequent rowing trips. Although she shares her given name with Alice Liddell, scholars disagree about the extent to which she was based upon Liddell. Characterized by Carroll as "loving and gentle", "courteous to all", "trustful", and "wildly curious",[1] Alice has been variously seen as clever, well-mannered, and sceptical of authority, although some commentators find more negative aspects of her personality. Her appearance changed from Alice's Adventures Under Ground, the first draft of Alice's Adventures in Wonderland, to political cartoonist John Tenniel's illustrations of her in the two Alice books. Alice has been identified as a cultural icon. She has been described as a departure from the usual nineteenth-century child protagonist, and the success of the two Alice books inspired numerous sequels, parodies, and imitations, with protagonists similar to Alice in temperament. She has been interpreted through various critical approaches, and has appeared and been re-imagined in numerous adaptations, including Walt Disney's film (1951). Her continuing appeal has been ascribed to her ability to be continuously re-imagined.
