Hungarian-American investor George Soros has been the subject of conspiracy theories since the 1990s.

Incidents such as the 1955 bombing of the Kashmir Princess, the 1985 Arrow Air Flight 1285 crash, the 1986 Mozambican Tupolev Tu-134 crash, the 1987 Helderberg Disaster, the 1988 bombing of Pan Am Flight 103, and the 1994 Mull of Kintyre helicopter crash, as well as various aircraft technologies and alleged sightings, have all spawned theories of foul play which deviate from official verdicts. The destruction of Korean Air Lines Flight 007 by Soviet jets in 1983 has long drawn the interest of conspiracy theorists.
The theories range from allegations of a planned espionage mission, to a US government cover-up, to the consumption of the passengers' remains by giant crabs.
These variously include allegations that it was secretly Flight MH370, that it was part of a conspiracy to conceal the 'truth' about HIV (seven disease specialists were on board), or that the Ukrainian army, the Illuminati or Israel was responsible.

Conspiracy theories concerning the Illuminati, a short-lived eighteenth-century Enlightenment society, appear to have originated in the late nineteenth century, when some conservatives in Europe came to believe that the group had been responsible for the French Revolution of 1789-1799.
Hoaxes about the Illuminati were later spread in the 1960s by a group of American practical jokers known as the Discordians, who, for example, wrote a series of fake letters about the Illuminati to Playboy magazine.
