The exact age of King Arthur at the time of his death is not definitively known, as his story is a blend of historical facts and legendary tales. According to most legends, King Arthur died in the Battle of Camlann, which is said to have taken place around 537 AD. If we consider the traditional accounts that place his birth around the late 5th century, it is estimated that King Arthur was likely in his late 40s or early 50s when he died.
However, it’s important to note that King Arthur’s age at death varies depending on the source. Some stories suggest he was older, while others imply he was younger. The lack of concrete historical records makes it difficult to determine his exact age at the time of his death.
