• The London Monster

  This theory centers on the late eighteenth-century panic over a mysterious attacker who used a sharp or glittering instrument to slash or prick women in the streets of London. While the historical core concerns a real public scare between 1788 and 1790, later explanations broadened the threat into something more organized: a gang, a moral plague, or even a covert medical experiment involving “shining needles.” The documented record clearly shows that the London Monster panic was real and that thousands of women feared random assault. What remains unresolved is whether the phenomenon centered on one attacker, multiple imitators, mass panic, or a more speculative experimental explanation.

• The Great Chicago Fire (1871)

  This theory held that the Great Chicago Fire was not an accident but the work of a coordinated radical conspiracy—often described in later retellings as the “Communist International,” though contemporaries more commonly blamed “communists” or “the International.” In the fire’s aftermath, rumors spread that organized incendiaries had deliberately set multiple blazes in order to destroy the city, destabilize social order, or launch class war. The historical record clearly shows that such rumors circulated and that Chicago newspapers used explicitly anti-communist language about alleged “North Side incendiaries.” What remains unproven is the conspiratorial claim itself. The fire’s true origin was never established with certainty, and no evidence demonstrated a coordinated revolutionary arson campaign.
