In some monarchies, such as Saudi Arabia, succession to the throne usually first passes to the monarch's next eldest brother and so on through his other brothers, and only after them to the monarch's children (agnatic seniority). In some other monarchies (e.g., Jordan), the monarch chooses who will be his successor within the royal family, who need not necessarily be his eldest son.
