4 States and Political Institutions

The state, government, and sovereignty

A state is a durable political order that claims authority over a population and territory and organizes public law and administration. In its classic sense, sovereignty means supreme authority within a territory.

A government is the group of officeholders and bodies directing public affairs at a given time. It is not the same as the state: a state’s institutions and legal order can continue through changes in government and leadership.

Modern states typically rely on coordinated legislatures, courts, executive bodies, and administrative agencies to make, interpret, and enforce rules. The state’s reach varies: its formal authority does not necessarily match its practical ability to implement policy consistently across its territory.

Political institutions and public decision-making

Political institutions organize collective decision-making and shape how public power is gained, exercised, and constrained. They include formal and informal rules, practices, and regular patterns that guide and limit political action.

It is useful to distinguish institutions as rules of the game from the organizations that operate within those rules. A constitution, election law, or convention sets expectations and procedures; a legislature, court, political party, or civil service is an organization that interprets or operates under them. In everyday usage, institution can also mean an organization, so context matters.

Common state institutions include:

• Legislatures, which debate and enact laws and often oversee the executive.

• Executives, which lead government and direct public administration.

• Courts, which resolve disputes and interpret legal rules.

• Bureaucracies, which turn laws and policy decisions into routine administration.

• Electoral systems and political parties, which organize political competition and connect citizens to government.

Constitutions and laws distribute authority among these bodies. For example, a constitution may authorize a legislature to pass a law, require an executive agency to administer it, and empower a court to decide whether officials acted within their legal authority. Institutions therefore shape who can make decisions, which procedures apply, and how decisions can be challenged.

Formal and informal institutions

Formal institutions are officially recognized rules and procedures created or enforced through recognized public channels. Examples include constitutions, statutes, regulations, and election rules. Informal institutions are socially shared expectations and practices, usually unwritten, that are upheld outside official procedures. Examples include norms of political compromise, expectations that officials explain decisions, patronage practices, and conventions about how a legal power is used.

Informal institutions are more than habits: they shape behavior because people expect them to be followed or anticipate consequences when they are not. They interact with formal rules in several ways:

• Support: A norm of accepting lawful election results can help make an election procedure effective.

• Fill gaps: Conventions can guide how officials consult one another when written rules leave room for judgment.

• Undermine or circumvent: If officials routinely allocate public jobs through personal loyalty rather than open procedures, actual access to power may depend on networks even when written rules promise impartial administration.

Consider a hypothetical law requiring public hearings before a local government approves a major project. The formal rule specifies when a hearing must occur and who may speak. Informal practices affect whether residents receive meaningful notice, whether officials take criticism seriously, and whether influential groups receive greater access. Understanding how power works therefore requires comparing rules on paper with the practices that shape their application.

Power, authority, and legitimacy

Power is the ability to shape decisions or outcomes. It may operate through formal offices and legal powers, but also through control of information, resources, political organization, or access to decision-makers. Authority is power understood as a recognized standing to issue directives or make decisions.

Legitimacy concerns whether the exercise of authority is justified or accepted as rightful. It is not the same as simply having the ability to command or enforce. The distinction also separates a descriptive question—whether a government’s commands are generally obeyed—from the normative question of whether it has a justified right to rule.

Institutions connect leadership to these questions by specifying how leaders are selected, what they may do, and how they can be held accountable. A leader may have formal authority yet depend on cooperation from legislators, administrators, courts, local officials, and the public to carry out decisions. Informal networks may also give people influence that their official positions do not reveal. Understanding political organization therefore involves examining both the distribution of formal powers and the practical relationships through which those powers are exercised.

State capacity and institutions in practice

State capacity is the ability to carry out public decisions, including collecting revenue, administering services, enforcing laws, and maintaining public order. A state may possess extensive formal authority while having limited practical capacity to implement policy consistently across its territory.

The state’s capacity and the operation of its institutions depend not only on formal rules, but also on how people and organizations apply them. Formal rules establish official powers and procedures; informal norms and routines affect how those rules work in practice. Together, institutions distribute power, shape leadership, and influence both state capacity and the legitimacy of decisions.
