States, nations, governments, regimes, and sovereignty are often mixed together, but they do different jobs. You learn to tell them apart using maps, constitutions, borders, and real-world examples.

Political science grew from philosophy, law, history, economics, sociology, and statistics into a field with its own questions and tools. This chapter connects major political eras, institutions, and research methods to the way the discipline works today.

Political writing often mixes facts, values, assumptions, and claims about cause and effect. You practice reading speeches, opinion pieces, court opinions, and research summaries without losing the argument.

Race, gender, religion, class, ethnicity, language, and national identity shape power and belonging. You study representation, exclusion, identity formation, backlash, civil rights, and recognition politics.

Many political outcomes come from strategic choices where each actor reacts to others. You use simple game theory and public choice ideas to analyze bargaining, coordination, free riding, vetoes, and credible commitments.

Comparative politics asks why countries differ in institutions, conflict, prosperity, rights, and stability. You practice comparing countries without cherry-picking examples or ignoring history and context.

Governments need capacity to tax, deliver services, enforce rules, keep records, and respond to crises. This chapter covers state building, bureaucracy, public goods, clientelism, corruption, accountability, and trust.

Politics and markets constantly shape each other through taxes, regulation, spending, labor rules, property rights, and welfare policy. You connect economic interests to political coalitions and policy choices.

Development politics deals with growth, poverty, inequality, institutions, aid, extraction, and public services. You compare explanations for why some states become richer, more stable, or more inclusive than others.

Policy work turns public problems into choices among imperfect options. This chapter covers agenda setting, policy design, cost and benefit thinking, stakeholders, implementation risks, and evaluation.

Public administration is where laws become permits, inspections, benefits, schools, roads, health services, and enforcement. You cover agency routines, discretion, street-level workers, performance measures, procurement, and service quality.

You follow a practical policy workflow from problem definition to evidence, options, tradeoffs, recommendation, and final memo. The chapter helps you produce a clear brief for a decision-maker.

International politics begins with a world of sovereign states that lack a single world government. You cover anarchy, sovereignty, power, security, order, norms, and the difference between domestic and international authority.

International relations theories are tools for explaining war, cooperation, trade, institutions, and diplomacy. You use realism, liberalism, constructivism, feminism, Marxist approaches, and postcolonial views on the same cases.

States cooperate through embassies, treaties, summits, alliances, and international organizations. This chapter covers diplomacy, negotiation, the United Nations, regional organizations, NATO, and the politics of multilateral action.

International law affects war, trade, human rights, migration, oceans, climate, and courts, even when enforcement is uneven. You study treaties, customary law, compliance, war crimes, and human rights institutions.
