=== History ===

Christ myth theory – A fringe theory that proposes that the historical Jesus did not exist in any capacity whatsoever. While the divinity of Jesus is a matter of religious and philosophical rather than historical debate, Christian and non-Christian scholars of antiquity universally agree that Jesus of Nazareth was a Galilean Jew who lived in the first century, was baptized, and later crucified by Roman authorities. This is based on sources written by historians, scholars, and politicians who lived during the time of Christ.
Holocaust denial – Historical revisionist movements associated with Holocaust denial have employed pseudoscientific evidence and conspiracy theories published in intradiegetic pseudo-academic journals and presented at fringe conferences (e.g. misconstruing cyanide residue studies, claiming despite all evidence to the contrary that gas chambers were built after the war).
Khazar hypothesis of Ashkenazi ancestry –  A fringe theory that postulates that Ashkenazi Jews were primarily, or to a large extent, descended from Khazars, a multi-ethnic conglomerate of mostly Turkic peoples who formed a semi-nomadic khanate in and around the northern and central Caucasus and the Pontic–Caspian steppe. Genetic studies on Jews have found no substantive evidence of a Khazar origin among Ashkenazi Jews, with evidence suggesting the Ashkenazi have mixed Near Eastern and Southern European/Mediterranean origins.
New chronology (Fomenko) – pseudohistorical conspiracy theory which argues that events of antiquity generally attributed to the civilizations of the Roman Empire, Ancient Greece and Ancient Egypt, actually occurred during the Middle Ages, more than a thousand years later.

=== Linguistics ===
Japhetic theory – claim that the Afroasiatic, Basque, and Kartvelian language families share a common origin.
