Political science is a field that focuses on the theory and practice of government and politics at various levels, including local, state, national, and international contexts. It involves studying institutions, practices, and relationships that shape public life and citizenship. One key aspect of political science is understanding different political systems, such as constitutional democracies, federal systems, and confederations. The United States Constitution, for instance, outlines the American political system and serves as a foundation for exploring political theories and practices. Aristotle, in his works, used the term constitution to describe the arrangement of offices in a state, regardless of the quality of governance. Political science also encompasses subfields like political theory, international relations, and comparative politics, offering insights into the complex dynamics of power, nationalism, and the evolution of political institutions worldwide.

Political theory and the foundations of political community
Political theory is a key aspect of political science, focusing on the foundations of political communities and institutions. It involves the analysis of concepts such as peace, conflict, and violence in relation to political opinions and public life. Political theory also involves understanding the impact of historical contexts and new technologies on political thought and predicting potential challenges and outcomes. Classical political theory, for instance, focused on analysing the sources of conflict and establishing principles of justice to guide political organisations.
Political theory draws on enduring political writings from ancient Greece to the present, including works by moral philosophers. Plato, for instance, introduced the concept of a government composed of individuals representing the interests of the people and ruling on their behalf. The United States, founded long after Plato, is considered a republic based on his definition. Aristotle, a student of Plato, also contributed to the formulation of political science. He favoured a "polity" where all economic classes respect one another and capable individuals govern with the approval of the people. Notably, Aristotle viewed democracy as equivalent to anarchy.
Political theory also examines the writings and values that underpin political communities and institutions. It explores the moral purposes of political association and the functioning of political institutions in practice. Political theory provides a framework for understanding and addressing political issues, behaviours, and actions. For example, the theory may discuss the means by which individuals and groups come together, such as by addressing shared problems or critiquing liberal peace.
Political science, as a broader field, encompasses the study of government at all levels, laws, and political thought. It includes various subfields such as international relations, comparative politics, and political methodology. International relations, for instance, focuses on understanding the interactions between states and non-state actors, with international conflict being a significant area of study. Political methodology explores philosophical issues, such as the possibility of a science of politics and its similarities with other social sciences.

Federal systems and their distribution of power
Federalism is a system of government that divides power between a central authority and regional governments. It is often characterised by a structure of checks and balances and power-sharing, which proponents argue reduces threats and mitigates the risk of a central government becoming tyrannical. Federal systems can be differentiated by the degree of power distributed to regional governments, with some systems being almost completely unitary, and others being federations in name only.
In a federation, the division of power between federal and regional governments is typically outlined in a constitution. For example, the constitutions of Germany and the United States stipulate that powers not specifically granted to the federal government are retained by the states. Conversely, the constitutions of Canada and India state that powers not explicitly granted to provincial or state governments are retained by the federal government.
The distribution of powers in a federal system can vary, with certain powers being reserved for the federal government, shared between federal and regional governments, or left to the discretion of regional governments. For example, in the United States, the Tenth Amendment reserves certain powers for the states, including the creation of school systems, oversight of state courts, public safety, management of intrastate business and trade, and management of local governments. Concurrent powers, or powers shared by both federal and state governments, include taxation, road construction, and the creation of lower courts.
The distribution of fiscal powers, such as spending, taxation, and borrowing, is another important consideration in federal systems. One issue is whether to distribute these powers in a way that suppresses or allows competition among constituent governments. Federal systems can also vary in the number of regional governments or subunits they encompass, ranging from minimalistic federations with only two subunits to multi-regional federations with three or more.
Federalism can take on different forms, such as anarchist federalism, which rejects the statism and nationalism present in modern federations and instead emphasises stateless individuality and autonomy. Additionally, federal systems can be national or supranational, with the European Union serving as an example of the latter.

Nationalism and its role in international politics
Nationalism is a set of beliefs about the nation, including its origins, nature, and value. It presupposes the existence of a particular nation and promotes its interests, especially with the aim of gaining and maintaining its sovereignty and self-governance over its perceived homeland. It holds that each nation should govern itself, free from outside interference, and that a nation is the only rightful source of political power.
Nationalism has played a significant role in the constitution and configuration of the current international system, which is primarily composed of nation-states. It has influenced the formation of new nation-states, such as in central and eastern Europe after World War I, and continues to shape interactions between actors on the international plane.
Nationalism is often portrayed as a fundamental characteristic of international politics, and it informs the way state elites formulate and implement foreign policy. It can be a powerful force for change, challenging traditional and colonial structures and promoting national unity or solidarity.
However, nationalism can also be a divisive force, leading to political militancy, racial separatism, and even war. It has been associated with movements that seek to exclude minorities and promote racial purity. In international relations theory, nationalism is often treated as an independent variable that drives foreign policy decision-making, but it is also influenced by international factors and a country's foreign policy goals.
Nationalism continues to be a prevalent force in global politics, with the rise of nationalist parties and the impact of nationalist policies being observed in various countries. It remains an important ideology that shapes social and political experiences, influencing individuals' choices and actions.

Political methodology and the science of politics
Political science is the scientific study of politics, focusing on the theory and practice of government and politics at various levels, from local to international. It involves the analysis of political activities, institutions, thought, and behaviour, as well as the study of systems of governance and power. As a social science, political science faces the challenge of observing human actors who possess the capacity for conscious choice.
Political methodology, as a subfield of political science, explores philosophical issues surrounding the possibility of a science of politics and its relationship with other social sciences. It examines alternative modes of explanation and the validity of knowledge claims. Courses in this field provide training in research design, including experimental and non-experimental methods, and the use of statistics, mathematics, and computational tools for data analysis.
Political methodology also involves the study of political processes and behaviour, employing various empirical methods such as field experiments, surveys, case studies, process tracing, historical analysis, ethnography, participant observation, and interview research. Political scientists may also utilise theoretical frameworks like game theory and agent-based models to understand complex political dynamics.
The study of political methodology equips students with the skills to address broad questions in the field, such as evaluating American political institutions, ideas, and practices, and exploring ways to improve them. It encourages the development of critical thinking, analytical skills, and an understanding of the complexities inherent in the scientific study of politics.
In summary, political methodology plays a crucial role in advancing the science of politics by providing a toolkit for rigorous research and analysis, enabling scholars to gain insights into political phenomena and contributing to our understanding of political systems and behaviours.

Political systems and their historical development
One of the earliest known analyses of politics emerged in ancient China through the works of Confucius (551–479 BCE). Similarly, Kautilya (around 300 BCE) in India offered significant contributions to political thought. In the Western tradition, Plato (428/427–348/347 BCE) and Aristotle (384–322 BCE) are often regarded as foundational figures in political science. Aristotle, notably, introduced empirical observation into the study of politics and formulated a sixfold typology of political systems based on the number of persons ruling and the legitimacy of their rule. He distinguished between legitimate forms, such as monarchy, aristocracy, and polity, and their corrupt counterparts, tyranny, oligarchy, and democracy.
The conquest of the Mediterranean world by Alexander the Great, a pupil of Aristotle, brought about new political forms. Hellenistic thinkers, particularly the Stoics, promoted the concept of natural law, which laid the groundwork for Roman legalism and Christian notions of equality. The fall of the Roman Empire and the emergence of feudalism marked another significant shift in political systems. During this period, political entities transitioned from vague frontier-type boundaries to the more defined national boundaries that characterise modern nation-states.
The Napoleonic Wars, which spread the ideals of the French Revolution, played a pivotal role in fostering nationalism across Europe. Subsequently, the two world wars of the 20th century further advanced the principles of national self-determination and liberal democracy, leading to the emergence of new sovereign states in Eastern Europe, Asia, and Africa. The collapse of the Soviet Union marked the culmination of this process, reinforcing the primacy of the nation-state in international politics.
In the modern era, political systems have become increasingly complex, ranging from democratic to totalitarian regimes. Hybrid regimes, combining autocratic and democratic features, have also emerged, particularly in developing countries. Capitalism and the theories of Karl Marx have significantly influenced the understanding of political systems, highlighting the class dynamics inherent in political power structures.
In summary, the historical development of political systems has been a dynamic process, shaped by various philosophical, social, and economic forces. The study of this evolution is integral to political science, providing a deeper understanding of the interplay between political thought and its practical manifestations in society.

Frequently asked questions
Political science is a field of study that focuses on the theory and practice of government and politics at various levels, including local, state, national, and international. It involves understanding institutions, practices, and relations that shape public life and citizenship.
The constitution is a foundational document that outlines the structure and principles of a political system. It defines the distribution of power, the roles of different institutions, and the rights and responsibilities of citizens. Political scientists study various constitutional models, such as federal systems, to understand their impact on governance and political processes.
The constitution shapes the political system by establishing the rules and framework within which the government operates. For example, the U.S. Constitution describes the American political system, including the roles of the presidency, Congress, and the courts. It also influences policy formation and the interactions between different levels of government, such as the relationship between national and state governments.
There are several types of constitutional models, including presidential systems, parliamentary systems, and hybrid systems. A presidential system, like in the United States, features a directly elected president with significant executive powers. Parliamentary systems, on the other hand, are based on a legislature that selects a prime minister to lead the government. Some countries, like France, have a hybrid presidential-parliamentary system with both an elected president and a prime minister responsible for day-to-day governance.
