History of the World, Part I is a 1981 comedy film written, produced, and directed by Mel Brooks.

As he does in many of his other films, Brooks gives himself a great deal of time in front of the camera, this time playing five roles: Moses, Comicus the stand-up philosopher, Tomás de Torquemada, King Louis XVI, and Jacques, le garçon de pisse. The large ensemble cast also features Sid Caesar, Shecky Greene, Gregory Hines (in his film debut), Charlie Callas; and Brooks regulars Dom DeLuise, Madeline Kahn, Harvey Korman, Cloris Leachman, Andreas Voutsinas, and influential Irish comedy writer/actor and former Goon Show star Spike Milligan.

The film also has cameo appearances by Royce D. Applegate, Bea Arthur, Hugh Hefner, John Hurt (as Jesus Christ), Barry Levinson, Jackie Mason, Paul Mazursky, Andrew Sachs and Henny Youngman, among others. Orson Welles narrates each story.

Despite carrying the title Part 1, there was no sequel; the title is a play on The Historie of the World, Volume 1 by Sir Walter Raleigh, as detailed below.
