In 1820, Gregor MacGregor returned to London from South America claiming to have been named Cazique, or Prince, of Poyais, a lush, mineral-rich nation along the Black River in modern-day Honduras. Armed with charm, forged documents, and a meticulously detailed 352-page guidebook written under a pseudonym, MacGregor described a bustling capital city called St. Joseph, fertile soil yielding three harvests a year, rivers filled with gold nuggets, and friendly native tribes eager for British trade.
London was captivated. MacGregor opened a Poyaisian legation, issued land certificates, floated a massive 200,000-pound bond on the London Stock Exchange, and sold currency for his non-existent domain. In late 1822 and early 1823, seven ships carrying over 250 hopeful emigrants set sail for Poyais, carrying Poyaisian bank notes and titles to land.
When they arrived, instead of paved streets, grand government buildings, and tropical paradise, they found untouched, dense jungle, disease-ridden swamps, and hostile terrain. Over half of the settlers perished from yellow fever and malaria before being rescued by a passing vessel. Despite the horrific disaster and public outrage, MacGregor fled to France, where he attempted to run the exact same scheme again.
Amazingly, he managed to avoid significant legal consequences and eventually retired in Venezuela on a military pension.
