Without agreed rules and principles, international relations would be marked by constant uncertainty and conflict. This Series introduces you to the foundations and objectives of international law, helping you to appreciate why it is considered essential for regulating behaviour among nations and for promoting order in the international system. The aim of this Series is to equip you with the knowledge needed to define international law, explain its nature, and analyse its objectives and functions within the international system. By the end of the Series, you should be able to connect these foundations to the broader study of international organisations and politics. We shall commence this Series by examining the meaning and nature of international law, focusing on its definition, scope, and sources. Next, we will explore the objectives and functions of international law, highlighting its regulatory role and its contribution to peace and cooperation. Subsequently, we will consider the historical development of international law,
LA-NET | ONLINE LEARNING VIDEO PLATFORM FOR POST-SECONDARY & HIGHER INSTITUTION STUDENTS tracing its early foundations and modern evolution. Finally, we will wrap up by discussing the relationship between international law and international relations, paying attention to its limitations and challenges in practice. Series Learning Outcomes Upon completing this Series, you should be able to: SLO 1.1 define international law and explain its scope, SLO 1.2 analyse the characteristics and sources of international law, SLO 1.3 explain the objectives and functions of international law in regulating the international system, SLO 1.4 evaluate the historical development of international law from its early foundations to its modern evolution, and SLO 1.5 assess the relationship between international law and international relations, highlighting its limitations and challenges in practice. 1.1 Meaning And Nature Of International Law 1.1.1 Definition and scope International law refers to the body of rules and principles that govern the relations between states and other actors in the international system. It is distinct from domestic law because it operates across national boundaries and is created through agreements, customs, and practices recognised by the global community. The scope of international law extends to areas such as diplomacy, trade, human rights, environmental protection, and the regulation of armed conflict. To put it simply, international law provides a framework for cooperation and coexistence among nations. Without it, states would rely solely on power and unilateral decisions, which could lead to instability. Fill in the blank: International law is the body of rules and principles that govern the relations between ______ and other actors in the international system.

Figure 1.1: Comparison of domestic and international law 1.1.2 Characteristics and sources The characteristics of international law include its reliance on consent, its decentralised nature, and its dependence on enforcement through collective mechanisms rather than a single global authority. Unlike domestic law, international law does not have a central legislature or police force. Instead, compliance is encouraged through treaties, diplomatic pressure, and international institutions. The sources of international law are generally recognised as: Treaties: Formal agreements between states that are legally binding. Customary international law: Practices consistently followed by states out of a sense of legal obligation. General principles of law: Principles common to major legal systems, applied when treaties or customs are silent. Judicial decisions and scholarly writings: Subsidiary means for interpreting and clarifying the law. Fill in the blank: The two primary sources of international law are ______ and ______.

Which source of international law arises from consistent state practice accompanied by a sense of legal obligation? a) Treaties b) Customary international law c) Judicial decisions d) General principles of law 1.2 Objectives And Functions Of International Law 1.2.1 Regulatory role in the international system One of the primary objectives of international law is to regulate the conduct of states and other actors in the international system. Regulation here means establishing rules that guide behaviour, prevent conflict, and promote cooperation. For example, treaties on trade ensure that states follow agreed standards, while conventions on the environment set limits on harmful practices.

It provides predictability, which is essential for diplomacy, commerce, and peaceful coexistence. Fill in the blank: International law provides ______ in international relations by establishing rules that guide behaviour.

Figure 1.2: Regulatory role of international law 1.2.2 Promotion of peace, security, and cooperation Another major function of international law is the promotion of peace and security. Agreements such as the United Nations Charter prohibit the use of force except in self-defence or with Security Council authorisation. This helps to limit armed conflict and encourages peaceful dispute resolution. International law also fosters cooperation in areas such as human rights, health, and environmental protection. By creating shared standards, it enables states to work together on global challenges that no single country can solve alone. Fill in the blank: The United Nations Charter prohibits the use of ______ except in self-defence or with Security Council authorisation.

For example, treaties
LA-NET | ONLINE LEARNING VIDEO PLATFORM FOR POST-SECONDARY & HIGHER INSTITUTION STUDENTS between Mesopotamian city-states and codes of conduct in ancient Greece and Rome reflected early attempts to regulate relations beyond domestic boundaries. Later, classical thinkers such as Hugo Grotius, often referred to as the “father of international law”, laid down systematic principles in the seventeenth century. Grotius emphasised the importance of natural law and argued that states were bound by rules derived from reason and justice. His work provided a foundation for modern international legal thought. Fill in the blank: Hugo Grotius is often referred to as the “father of ______ law”. Image of Hugo Grotius or depiction of early treaties between states.
