Catherine de Medici, a prominent figure in French history, has been the subject of many rumors and legends, including the claim that she poisoned her son, King Francis II. However, there is no credible historical evidence to support this accusation. King Francis II died in 1560 at the age of 16, and his death was attributed to natural causes, specifically an ear infection that led to an abscess in his brain. Catherine de Medici was known for her political acumen and her efforts to maintain power, but there is no substantial proof that she was involved in her son’s death. The rumors likely stem from her controversial reputation and the many conspiracies that surrounded her during her lifetime. In conclusion, while Catherine de Medici’s life was filled with intrigue, the claim that she poisoned her son King Francis II remains unsubstantiated.
