Origin and evolution of International Law

The origin of International Law comes hand in hand with the rise of states. Among the oldest sources of International Law we can find a treaty between Mesopotamia and Umma around 3100 BC. This treaty regulated borders and their inviolability. But this is not the only example, in ancient times we can find several international treaties between two or more states that usually focused on border issues, peace agreements and treatment of foreigners. However, at that time there was no orderly legal system of these treaties or conventions.

Background of the modern international law system

One of the antecedents of the system of modern International Law was the treaty of Westphalia of 1648, signed by the majority of the European powers in the war of the 30s. This treaty established some of the fundamental pillars of the current legal framework.

Other relevant treaties such as the 1853 Paris Declaration on war at sea should also be mentioned; the Geneva Convention of 1864 on the treatment of military wounded in times of war and the Hague declarations of 1899 and 1907 to ensure the resolution of conflicts through peaceful means.

The first and second world wars imposed a terrible pause on the development of International Law. At the beginning of 1945 and after the end of the war, the States returned to the work of creating a legal framework that would help preserve peace, security and promote international cooperation.

The United Nations focused on the work of coding, ordering and developing a system that could maintain respect for the obligations emanating from international treaties. Among the UN agencies that have been created to enforce the international legal system are: the International Court of Justice, the Security Council and the General Assembly.
