Scope of leadership
One can govern oneself, or one can govern the whole earth. In between, we may find leaders who operate primarily within:
Intertwined with such categories, and overlapping them, we find (for example) religious leaders (potentially with their own internal hierarchies), work-place leaders (executives, officers, senior/upper managers, middle managers, staff-managers, line-managers, team-leaders, supervisors ...) and leaders of voluntary associations.
Some anthropological ideas envisage a widespread (but by no means universal) pattern of progression in the organisation of society in ever-larger groups, with the needs and practices of leadership changing accordingly. Thus simple dispute resolution may become legalistic dispensation of justice before developing into proactive legislative activity. Some leadership careers parallel this sort of progression: today's school-board chairperson may become tomorrow's city councilor, then take in (say) a mayordom before graduating to nation-wide politics. Compare the cursus honorum in ancient Rome.
