The legendary King Arthur from Arthurian legends is typically not portrayed as having biological children in the traditional tales. The legends mostly focus on King Arthur’s role as a king, his knights of the Round Table, and his relationship with Queen Guinevere and the wizard Merlin. The stories of King Arthur vary across different versions and adaptations, and the portrayal of his family and children can differ as well.
In some modern adaptations and retellings of the Arthurian legends, there may be variations that include King Arthur having children or descendants, but these are not part of the original Arthurian lore. The stories of King Arthur are a blend of historical, mythological, and literary elements, and they have evolved over time through various retellings and interpretations.
