What this dot point is asking
The SQA wants you to define power, authority and legitimacy precisely, distinguish them from one another, explain the different forms power can take, set out Max Weber's three types of authority, and explain why legitimacy underpins stable government. These concepts are the foundation of the whole Political Theory section and recur in questions on democracy and ideologies, so getting the definitions exact is essential.
The answer
Power
Power can be exercised in several ways. Force and coercion compel obedience through violence or the threat of it, such as a police crackdown or military rule. Persuasion and influence win people over through argument, reputation or the media. Incentives and rewards secure compliance by offering benefits. A government uses a mix of these, but power exercised purely through force tends to be resented and unstable.
Authority
The crucial distinction is that power and authority can come apart. An armed gang can hold power over a neighbourhood through fear but has no authority. A respected institution can hold authority that people accept even when it cannot physically compel them. Stable politics depends on power and authority going together.
Weber's three types of authority
Weber argued that modern democracies rest mainly on legal-rational authority, which is why a Prime Minister's authority comes from holding the office under accepted rules, not from personal charisma or inheritance.
Legitimacy
Legitimacy is gained in different ways: through free elections that give a mandate, through tradition and continuity, through legal and constitutional process, and through performance (delivering security and prosperity). A government that loses legitimacy faces protest, civil disobedience and ultimately collapse, even if it still holds the instruments of power.
Examples in context
A military junta that seizes control in a coup may hold power through the army but lack legitimacy, so it faces strikes and protest until it either wins acceptance or is overthrown. A long-standing constitutional monarchy combines traditional authority (the Crown) with legal-rational authority (an elected parliament under accepted rules), which gives it deep legitimacy. A charismatic protest leader can mobilise a movement through personal authority, but that movement often struggles to institutionalise once the leader is gone, illustrating Weber's point that charismatic authority is powerful but unstable. These examples let a Higher answer evaluate why legitimacy, not raw power, is the foundation of durable government.

- Cue. Power is the ability to make others act; it can rest on force or coercion, persuasion, or incentives and rewards.
Q2. Describe Weber's three types of authority. [6 marks]
- Cue. Traditional (custom and inheritance), charismatic (personal qualities of a leader), and legal-rational (accepted rules and offices, the basis of modern democracies).

A -mark analysis question, roughly half knowledge and understanding and half analysis. Markers reward a clear conceptual distinction developed with examples.
KU should define power as the ability to make others do something they would not otherwise do, and authority as the right to exercise power that others accept as rightful. Naming the means of power (force, coercion, persuasion, incentives) and Weber's three types of authority strengthens KU.
Analysis marks come from explaining why the distinction matters: a regime can hold power through force but lack authority, which makes it unstable, whereas authority lets a government rule by consent. A developed judgement that authority is more durable than naked power lifts the answer.

A -mark essay: up to marks for knowledge and understanding and up to for analysis, evaluation and a sustained conclusion.
KU comes from defining legitimacy as the rightful and accepted use of power, explaining how it is gained (elections, tradition, legal process, performance) and linking it to consent and obedience. Weber's legal-rational authority and the idea of consent give precise KU.
Evaluation marks come from weighing how far legitimacy is essential against cases where states survive on coercion alone, and judging that while force can sustain a regime briefly, lasting stability depends on legitimacy. A sustained conclusion directly answering "essential" is the discriminator.
