Padmé Amidala, also known as Padmé Naberrie, was a prominent character in the Star Wars prequel trilogy, serving as the Queen of Naboo and later as a Senator in the Galactic Republic. Her character was portrayed by Natalie Portman in the films.

Padmé’s age at the time of her death has been a topic of debate among Star Wars fans, as it is never explicitly stated in the films. However, based on various clues and hints provided in the films and other sources, we can make an educated guess as to her age at the time of her death.
In Star Wars Episode II: Attack of the Clones, which takes place 10 years before the events of Star Wars Episode III: Revenge of the Sith, Padmé states that she is 24 years old. This means that she would be 34 years old at the time of the events of Revenge of the Sith, which is when she dies.
Additionally, in the novelization of Revenge of the Sith, Padmé is described as being “in her mid-thirties.” This further supports the idea that she was around 34 years old at the time of her death.
It’s worth noting that some fans have suggested that Padmé may have been older than 24 in Attack of the Clones, as her portrayal in the film seems more mature and experienced than a 24-year-old would typically be. However, this could be explained by the fact that Padmé had been a queen and a senator for many years by that point, which would have required her to be mature and knowledgeable beyond her years.
In Revenge of the Sith, Padmé dies shortly after giving birth to her twin children, Luke and Leia Skywalker. The cause of her death is never explicitly stated in the film, but it is strongly implied that she died of a broken heart, brought on by the emotional trauma of losing her husband, Anakin Skywalker, to the dark side of the Force and seeing him become the evil Sith Lord, Darth Vader.
Some fans have criticized this explanation for Padmé’s death, arguing that it seems unlikely that a strong and resilient character like Padmé would simply give up and die due to emotional trauma. However, it’s worth noting that the Star Wars universe is one where the power of the Force can have a strong influence on people’s emotions and actions, so it’s not entirely implausible that Padmé could have been so overwhelmed by grief and despair that she died as a result.
In conclusion, Padmé Amidala was around 34 years old at the time of her death in Star Wars Episode III: Revenge of the Sith. While the cause of her death is not explicitly stated in the film, it is strongly implied that she died of a broken heart brought on by the emotional trauma of losing her husband and seeing him become the evil Darth Vader.
