Claims that someone other than William Shakespeare of Stratford-upon-Avon wrote the works traditionally attributed to him were first explicitly made in the 19th century, though supporters of the theory often argue that coded assertions of alternative authorship exist in texts dating back to Shakespeare's lifetime. Typically, they say that the historical Shakespeare was merely a front to shield the identity of the real author or authors, who, for reasons such as social rank, state security, or gender, could not safely take public credit. Although these claims have attracted much public interest, all but a few Shakespeare scholars and literary historians consider them to be fringe theories with no hard evidence, and for the most part disregard them except to rebut or disparage the claims.
