I want to know the answer to the following question:
What did the rota system do?
All the background I'm provided with is that "An unconventional power succession system was established (rota system) whereby power was transferred to the eldest member of the ruling dynasty rather than from father to son, i.e. in most cases to the eldest brother of the ruler, fomenting constant hatred and rivalry within the royal family.[citation needed]". Is that enough to answer the question?
