• The "Metric" Conspiracy

  This theory claimed that the metric system was not just a new way to measure the world but a French revolutionary plot to strip creation of its sacred proportions by replacing older, divinely sanctioned measures such as the inch and foot with abstract decimal units. It emerged from the openly revolutionary origins of the metric system in late eighteenth-century France and was sustained in later anti-French, anti-secular, and anti-centralizing arguments. In hostile readings, the metric system became an ideological weapon disguised as rationalization.

• The "Lost Dauphin" (Louis XVII)

  This theory holds that Louis XVII, the imprisoned son of Louis XVI and Marie Antoinette, did not die in the Temple prison in 1795 but was secretly removed and hidden by royalist sympathizers. In its strongest versions, the child was smuggled out through a substitution scheme, raised under another identity, and later either concealed by a royalist cabal in Europe or transported to North America for protection. The theory became one of the great political survival legends of post-revolutionary France, producing dozens of pretenders and eventually more than a hundred claimants. Although modern DNA testing on the preserved heart attributed to the child strongly supports the official death in prison, the Lost Dauphin legend remains one of the most persistent royal escape narratives in modern history.
