Introduction
Political science is a broad field that studies how societies are governed and how power operates within them. To understand politics more effectively, the discipline is divided into various branches or sub-disciplines, each focusing on specific aspects of political life. The major sub-disciplines include Political Theory, Political Philosophy, Political Economy, Comparative Politics, Public Administration, and International Relations.
- Political Theory
Political theory is a branch of political science that deals with the critical and systematic analysis of political ideas, values, and practices. It examines concepts such as justice, freedom, authority, and equality, and seeks to understand the underlying principles of political systems and behavior. Although closely related to political philosophy, political theory focuses more on analyzing and interpreting existing political ideas and institutions, drawing from the works of philosophers to explain and evaluate political practice.
- Examples: The theories of John Locke on natural rights, Karl Marx’s theory of class struggle, and John Rawls’ theory of justice.
- Political Philosophy
Political philosophy is a branch of political science concerned with the normative and ethical foundations of political life. It explores questions such as what constitutes justice, what makes political authority legitimate, and what rights and duties citizens possess. Political philosophy seeks to prescribe how political life should be organized and what moral values should guide governance and human interaction. Political philosophy focuses on what ought to be in political life.
- Examples: Plato’s Republic (ideal state), Aristotle’s Politics, and Thomas Hobbes’ Leviathan.

- Political Economy
Political economy originally referred to the systematic study of how states organize and manage economic activity, as seen in classical works like Adam Smith’s The Wealth of Nations. In modern terms, political economy examines the relationship between politics and economics. How political institutions, decisions, and power structures affect economic policies, wealth distribution, and national development.
- Examples: The link between Dangote Group and the Nigerian government shows Nigeria’s political economy. Government policies and incentives influence Dangote’s business growth. The Dangote Refinery impacts national development and job creation. This reflects how politics and economics work together in shaping Nigeria’s economy.
- Comparative Politics
Comparative politics, originally known as comparative government, is the sub-discipline of political science that studies and compares political systems, institutions, and processes across different countries. It seeks to identify patterns, causes, and effects in political behavior and governance to understand how different political systems function and influence social outcomes.
- Examples: Comparing the presidential system of the United States with the parliamentary system of the United Kingdom, or studying democratic vs. authoritarian regimes.
- Public Administration
Public administration deals with the organization and management of government affairs. It focuses on how public policies are implemented and how government institutions deliver services to citizens efficiently.
- Examples: The civil service system, policy formulation, and bureaucratic reforms in governance.
- International Relations
International relations studies the interaction among states and global actors. It explores issues like diplomacy, war, peace, international organizations, and global governance.
- Examples: The role of the United Nations, foreign policy of major powers, and international trade relations.
Conclusion
In summary, political science is divided into several interrelated sub-disciplines that collectively help us understand political life — from ideas and ideologies to institutions and international relations. Each branch provides a unique lens through which we can analyze how power operates, how societies are governed, and how nations interact in a complex global system.
