Here's what we know:
* No credible evidence: There is no historical record or evidence to support the claim of a poisoned dress. No contemporary accounts mention such a thing.
* Elizabeth I's death: The official cause of Elizabeth I's death in 1603 was reported as "old age and debility," which aligns with the common health problems of the time.
* The myth: The myth likely stems from the fact that Elizabeth I was very cautious about her health and security, as she was a powerful queen in a turbulent time. It's possible that this fear of assassination led to the spread of rumors, including the story of the poisoned dress.
While it's possible that Elizabeth I may have been the target of an assassination attempt, there is no evidence to suggest that she was poisoned by a dress. The claim remains a popular myth that has been passed down through the years but lacks any real historical basis.
