History of Mongolia
Although the Xiongnu finally had been split into two parts in AD 48, the Xianbei (or Hsien-pei in Wade–Giles) had moved (apparently from the east) into the region vacated by the Xiongnu. The Xianbei were the northern branch of the Donghu (or Tung Hu, the Eastern Hu), a proto-Mongol group mentioned in Chinese histories as existing as early as the 4th century BC. The language of the Donghu is believed to be proto-Mongolic to modern scholars. The Donghu were among the first peoples conquered by the Xiongnu. Once the Xiongnu state weakened, however, the Donghu rebelled. By the 1st century AD, two major subdivisions of the Donghu had developed: the proto-Mongolic Xianbei in the north and the Wuhuan in the south.
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.
