Final answer:
In Arthurian Legend, the new king is determined by pulling Excalibur from the stone, feats of bravery and skill, and the support of the people.
Step-by-step explanation:
After Uther's death, the new king in the context of Arthurian Legend is determined through a series of tests and challenges. The most famous of these is the pulling of Excalibur from the stone, which only the rightful king can accomplish. The person who successfully pulls out the sword is recognized as the true king.
Another way to determine the new king is through feats of bravery and skill, such as winning battles or tournaments. A king who demonstrates leadership and earns the respect of the knights and nobles is more likely to be accepted as the new ruler.
In some versions of the legend, an announcement is made and the people are asked to accept or reject the new king. Their support and loyalty play an important role in determining the legitimacy of the new ruler.
