At the end of the 18th century, France witnessed the downfall of the Bourbon dynasty. King Louis XVI was executed, and his wife and son were imprisoned. Louis XVII, a mere child of seven or eight, struggled to survive amidst the storm of revolution. He was raised by a staunch Jacobin who aimed to mold him into a future citizen of the republic. However, the exiled royalists declared him the new king, a move fraught with political intrigue.

After the Thermidorian Reaction, Louis XVII's fate took a turn for the worse. The Thermidorian government feared he would be captured by royalists, leading to his imprisonment in the Temple prison. According to prison records, Louis XVII died in captivity on June 8, 1795, at the tender age of 10. Yet, the question of whether he truly died has long been shrouded in controversy and speculation.

The Bourbon dynasty attempted to unravel this mystery upon its restoration, but numerous individuals claimed to be the real Louis XVII. Among the most notable was Karl Wilhelm Naundorff, who asserted that he survived the Temple prison and even gained recognition from the King of Prussia. However, as evidence mounted, his identity became increasingly dubious.

Historians have conducted extensive research on this enigma, striving to uncover the truth. However, due to political influences, this mystery remains unresolved.
