Wikipedia:Articles for deletion/List of Nigerian traditional rulers
if I understand this rightly, these individuals pass  by dint of their office.  If I understand rightly, these individuals are "politicians who have held international, national or sub-national office"; surely a monarch within a larger country holds sub-national office.  If we grant my point, there's no real difference between this list and List of current United States governors, because both are lists of sub-national head executives
