The Springer Hoax was a scam starting in the mid 19th century, often using a phony genealogy in various ways to collect money based on the supposed estate of prominent colonialist Charles (Carl Christopher) Springer and debts said to be owed to him by various government agencies of Wilmington, Delaware and Stockholm, Sweden. The alleged estate was said to include 1,900 acres of land, 228 acres of which ran though the center of Wilmington, worth up to $150,000,000. Other claims included $100,000,000 deposited in a Stockholm bank. It is notable today primarily as the result of mistaken reliance on the various fraudulent and/or erroneous Springer genealogies going back to Adam and Eve via Emperor Charlemagne.
Wilmington's supposed debt was related to land purportedly owned by Springer. The land actually had belonged to Old Swedes' Church. Springer was merely a life trustee for the land. The tie to Sweden was based on a phony genealogy used to claim that Springer was part of the Swedish Aristocracy.
Good King Dagobert (French title: Le Bon Roi Dagobert; in Italian: Dagobert) is a 1984 French-Italian film directed by Dino Risi.
The film is inspired by a popular song against the French monarchy, created during the French Revolution.
During the 7th century, the lazy and messy King Dagobert I goes to Rome to ask Pope Honorius I for forgiveness of his sins of revelry and fornication. But Dagobert does not know that the pope, while he is still traveling, was replaced in a conspiracy by a perfect double. The replacement is a crude and rude man, even more stupid than Dagobert.
