What Is International Law?

Defining international law is a task involving many important factors. These include the international community’s willingness to abide by rules that are generally accepted as the rule of international law.

International law has expanded over the years to include a broad range of rules and procedures. The legal responsibilities of individuals within states are defined, along with the legal obligations of other international actors. International law regulates international trade, international communications, the environment, and more.

Until the 19th century, international law was largely confined to treaties between states. Various international agreements were negotiated by polities across the world, from eastern Mediterranean to East Asia. These treaties were generally non-binding, except as matters of honor.

During the 18th century, the concept of natural rights gained prominence in international politics. The emergence of centralized states like Spain and France brought wealth and more trade, and these states were able to establish more sophisticated rules of conduct.

During the 19th century, international organizations gained in prominence, leading to the creation of the League of Nations in 1919. The United Nations was established in 1945. The growth of international organizations has fueled the development of international law. These organizations have negotiated various agreements on environmental issues, including the Convention on Biological Diversity.

In addition to its role as a means of international interaction, international law also provides a set of procedures for resolving disputes. International disputes are usually concerned with territorial sovereignty, nationality, rights of passage, and non-use of force.
