Authority refers to the legitimate power to make decisions and enforce compliance, recognized and accepted by those subject to it. Max Weber identified three ideal types of authority:

• Traditional Authority: Based on long-standing customs, traditions, and established beliefs (e.g., monarchies, tribal elders). Legitimacy stems from 'it has always been this way.'
• Charismatic Authority: Derived from the exceptional qualities, heroism, or supernatural powers attributed to an individual leader (e.g., prophets, revolutionary figures). It is often unstable and dependent on the leader's personal appeal.
• Rational-Legal Authority: Based on a system of rules, laws, and procedures, typically found in modern bureaucracies and states. Legitimacy comes from the legality of rules and the right of those in authority to issue commands under these rules.

Forms of Political Organization (Elman Service's Typology): Societies organize politically in various ways, often correlating with their subsistence strategies and population size:

• Bands: Small, egalitarian, nomadic hunter-gatherer groups. Leadership is informal, based on skill and charisma, with decisions made by consensus. No formal authority.
• Tribes: Larger, settled groups (horticulturalists/pastoralists). Kinship-based organization. Leadership by headmen or 'big men' (achieved status) with limited formal authority. Decisions often by consensus or councils.
• Chiefdoms: Hierarchical societies with a centralized political authority (chief), often hereditary. Chiefs control resources and labor, and social stratification emerges.
• States: Highly centralized, stratified societies with formal governmental institutions, laws, and a monopoly on the legitimate use of force. Characterized by bureaucracy, taxation, and specialized roles.

Understanding authority and political organization is crucial for analyzing how societies maintain order, allocate resources, and evolve complex social structures.
