Final answer:
The inheritance of the role of a king or leader in Thelol society may be based on various historical practices, ranging from the eldest son inheriting the throne to the most capable or chosen individual being appointed.
Step-by-step explanation:
In traditional societies, rules of succession to leadership or the throne varied significantly, influenced by local customs, power structures, and familial arrangements. Examining the historical examples provided, we can deduce that the most likely way for someone to inherit the role of king or leader in Thelol society could depend on various factors. These could include the preference for elder sons in patrilineal societies, as seen with the Zhou aristocracy, where the eldest son inherits the leadership role. Alternatively, if Thelol society values merit or military prowess, a model similar to the Tang dynasty's practice of 'tanistry' might be in place, where the most capable individual, even if not the eldest, can claim the throne. Additionally, the Mongol Empire's approach of choosing one son to inherit the overarching leadership while dividing territory among siblings suggests another method of succession where the designated heir is chosen for his specific traits or abilities.
