Xiongnu
The Xiongnu () were a confederation of nomadic peoples who, according to ancient Chinese sources, inhabited the eastern Asian Steppe from the 3rd century BC to the late 1st century AD. Chinese sources report that Modu Chanyu, the supreme leader after 209 BC, founded the Xiongnu Empire.
Xenu
On December 24, 1994, the Xenu story was published on the Internet for the first time in a posting to the Usenet newsgroup alt.religion.scientology, through an anonymous remailer. This led to an online battle between Church of Scientology lawyers and detractors. Older versions of OT levels I to VII were brought as exhibits attached to a declaration by Steven Fishman on April 9, 1993, as part of "Church of Scientology International v. Fishman and Geertz". The text of this declaration and its exhibits, collectively known as the Fishman Affidavit, were posted to the Internet newsgroup alt.religion.scientology in August 1995 by Arnie Lerma and on the World Wide Web by David S. Touretzky. This was a subject of great controversy and legal battles for several years. There was a copyright raid on Lerma's house (leading to massive mirroring of the documents) and a suit against Dutch writer Karin Spaink—the Church bringing suit on copyright violation grounds for reproducing the source material, and also claiming rewordings would reveal a trade secret.
