Reptilians

Reptilians (also called archons, reptoids, reptiloids, saurians, draconians, or lizard people) are reptilian humanoids, which play a prominent role in fantasy, science fiction, ufology, and conspiracy theories. The idea of reptilians was popularised by David Icke, a conspiracy theorist who claims shapeshifting reptilian aliens control Earth by taking on human form and gaining political power to manipulate human societies. Icke has stated on multiple occasions that many world leaders were, or are possessed by, so-called reptilians.

Origins
Michael Barkun, professor of political science at Syracuse University, posits that the idea of a reptilian conspiracy originated in the fiction of Conan the Barbarian creator Robert E. Howard, in his story "The Shadow Kingdom" (1929). This story drew on theosophical ideas of the "lost worlds" of Atlantis and Lemuria, particularly Helena Blavatsky's The Secret Doctrine (1888), with its reference to "'dragon-men' who once had a mighty civilization on a Lemurian continent".
Howard's "serpent men" were described as humanoids (with human bodies and snake heads) who were able to imitate humans at will, and who lived in underground passages and used their shapechanging and mind-control abilities to infiltrate humanity. Clark Ashton Smith used Howard's "serpent men" in his stories, as well as themes from H. P. Lovecraft, and he, Howard and Lovecraft together laid the basis for the Cthulhu Mythos.
In the 1940s, American occultist Maurice Doreal (also known as Claude Doggins) wrote a pamphlet entitled "Mysteries of the Gobi" that described a "serpent race" with "bodies like man but...heads...like a great snake" and an ability to take human form. These creatures also appeared in Doreal's poem "The Emerald Tablets", in which he referred to Emerald Tablets written by "Thoth, an Atlantean Priest king". Barkun asserts that "in all likelihood", Doreal's ideas came from "The Shadow Kingdom", and that in turn, "The Emerald Tablets" formed the basis for David Icke's book, Children of the Matrix (2001).
Historian Edward Guimont has argued that the reptilian conspiracy theory, particularly as expounded by Icke, drew from earlier pseudohistorical legends developed during the colonisation of Africa, particularly surrounding Great Zimbabwe and the mokele-mbembe.…
