History's Greatest Mysteries is an American documentary television series that aired on the History Channel.

Overview

The 154 episodes of the series were produced from 1998 to 2011. Each season consisted of 12 to 14 one-hour episodes that focused on historical events or subjects considered to be mysterious by the general public. Episodes typically begin with Kent giving a broad overview of the subject followed by what is commonly accepted as explanation. During the main segments, experts on both sides of the issue present their evidence and opinions. Before commercial breaks, Kent would give the audience bits of trivia relating to the subject; episodes also included a timeline which would give important events occurring around the time of the events discussed in the show. Subjects covered on the show ranged from the beginning of human history to modern subjects such as Carlos the Jackal, The Amityville Horror, and Area 51, as well as political conspiracies and conspiracy theories such as MK ULTRA and the JFK Assassination. Common aspects of history covered on the show include religion, crime, the supernatural, archaeology, mythology, and folklore. Some episodes of the show were repackaged as part of a series called "Incredible but True?", which aired episodes of History's Mysteries as well as other shows (including In Search of History and UFO Files, also narrated by Ackroyd). The show's last episodes were an anthology of clips from previous episodes (such as Mysteries of the High Seas). Although new episodes are no longer being produced, re-runs of History's Mysteries are regularly shown on the History Channel. Additionally, they are available on DVD.
