International Relations (IR) are the interactions among sovereign states. The scientific study of those interactions is called international studies, international politics, or international affairs. In a broader sense, it concerns all activities among states—such as war, diplomacy, trade, and foreign policy—as well as relations with and among other international actors, such as intergovernmental organizations (IGOs), international nongovernmental organizations (INGOs), international legal bodies, and multinational corporations (MNCs). There are several schools of thought within IR, of which the most prominent are realism, liberalism, and constructivism.
International relations theory is the study of international relations (IR) from a theoretical perspective. It seeks to explain behaviors and outcomes in international politics. The four most prominent schools of thought are realism, liberalism, constructivism, and rational choice. Whereas realism and liberalism make broad and specific predictions about international relations, constructivism and rational choice are methodological approaches that focus on certain types of social explanation for phenomena.

International security is a term which refers to the measures taken by states and international organizations, such as the United Nations, European Union, and others, to ensure mutual survival and safety. These measures include military action and diplomatic agreements such as treaties and conventions. International and national security are invariably linked. International security is national security or state security in the global arena.
In international relations theory, realism is one of the dominant schools of thought, theoretically formalizing the statesmanship of Realpolitik of early modern Europe. Although a highly diverse body of thought, realism is unified by the belief that world politics is always and necessarily a field of conflict among actors pursuing wealth and power. The theories of realism contrast with the cooperative ideals of liberalism in international relations.
Critical international relations theory is a diverse set of schools of thought in international relations (IR) that have criticized the theoretical, meta-theoretical and/or political status quo, both in IR theory and in international politics more broadly – from positivist as well as postpositivist positions. Positivist critiques include Marxist and neo-Marxist approaches and certain ("conventional") strands of social constructivism. Postpositivist critiques include poststructuralist, postcolonial, "critical" constructivist, critical theory, neo-Gramscian, most feminist, and some English School approaches, as well as non-Weberian historical sociology, "international political sociology", "critical geopolitics", and the so-called "new materialism". All of these latter approaches differ from both realism and liberalism in their epistemological and ontological premises.
In international relations (IR), constructivism is a social theory that asserts that significant aspects of international relations are shaped by ideational factors. The most important ideational factors are those that are collectively held; these collectively held beliefs construct the interests and identities of actors.
In international relations theory, the concept of anarchy is the idea that the world lacks any supreme authority or sovereignty. In an anarchic state, there is no hierarchically superior, coercive power that can resolve disputes, enforce law, or order the system of international politics. In international relations, anarchy is widely accepted as the starting point for international relations theory.

Neoclassical realism is a theory of international relations and an approach to foreign policy analysis. Initially coined by Gideon Rose in a 1998 World Politics review article, it is a combination of classical realist and neorealist – particularly defensive realist – theories.
International ethics is an area of international relations theory which in one way or another concerns the extent and scope of ethical obligations between states in an era of globalization. Schools of thought include cosmopolitanism and anti-cosmopolitanism. Realism, Liberalism, and Marxism are ethical traditions that conceptually address moral issues in international relations.
In international relations theory, the Great Debates refer to a series of disagreements between international relations scholars. Ashworth describes how the discipline of international relations has been heavily influenced by historical narratives and that "no single idea has been more influential" than the notion that there was a debate between utopian and realist thinking.
Green theory is a theory of International Relations (IR). In contrast to mainstream theories of IR, it posits environmental issues as central to the study of international relations. According to green theory, mainstream theories like neorealism and neoliberalism fail to understand environmental problems through their rationalist and state-centric frameworks of analysis. Green theory focuses on the study of global justice, international development, modernization, and security. Green perspectives in IR emerged in the 1970s as a response to the increase of transnational issues related to the environment. By the end of the 20th century, green theory had established itself within the discipline. Green theory aligns itself with postpositivism that emerged from the so-called third debate of IR. The theory can be divided into an International political economy (IPE) oriented wing and a cosmopolitan wing. Initially, the IPE wing, mainly interested in environmental regimes, was stronger, but subsequently many cosmopolitan theorists, like David Held, Andrew Linklater, Henry Shue, and Thomas Pogge, have made contributions related to environmental issues.
The Orthodox Development view equates economic growth with 'development'. The gross national product of a country has continually been used by intergovernmental organisations such as the UN, to equate their economical stance to their level of 'development'. This approach to human progress has been critiqued consistently throughout its history, especially by economists such as Dambisa Moyo, with the main criticisms being that the approach is ethnocentric and one-dimensional.
Classical realism is an international relations theory from the realist school of thought. Realism makes the following assumptions: states are the main actors in the international relations system, there is no supranational international authority, states act in their own self-interest, and states want power for self-preservation. Classical realism differs from other forms of realism in that it places specific emphasis on human nature and domestic politics as the key factor in explaining state behavior and the causes of inter-state conflict. Classical realist theory adopts a pessimistic view of human nature and argues that humans are not inherently benevolent but instead they are self-interested and act out of fear or aggression. Furthermore, it emphasizes that this human nature is reflected by states in international politics due to international anarchy.
