A hierarchical organization or hierarchical organisation is an organizational structure where every entity in the organization, except one, is subordinate to a single other entity. This arrangement is a form of hierarchy. In an organization, this hierarchy usually consists of a singular/group of power at the top with subsequent levels of power beneath them. This is the dominant mode of organization among large organizations; most corporations, governments, criminal enterprises, and organized religions are hierarchical organizations with different levels of management power or authority. For example, the broad, top-level overview of the hierarchy of the Catholic Church consists of the Pope, then the Cardinals, then the Archbishops, and so on. Another example is the hierarchy between the four castes in the Hindu caste system, which arises from the religious belief "that each is derived from a different part of the creator God’s (Brahma) body, descending from the head downwards."
