The body of laws, principles, and guidelines that are commonly accepted as obligatory between states is referred to as international law, also known as public international law and the law of nations. In a wide range of areas, including conflict, diplomacy, economic ties, and human rights, it creates normative norms and a shared conceptual framework for states.

International Law Types

Public international law and private international law are two significant divisions of international law.

      Public International Law

   International institutions and certain governments are subject to laws and regulations known as public international law. Additionally, it creates rules for everything that has an impact on people, such as the environment, international trade, the ocean, and human rights.

States and international organisations like the United Nations, the World Trade Organization, the Bank for International Settlements (BIS), etc. are subject to public international law.

Public international law has a number of facets, including:

  • Customs
  • Accepted global standards of conduct
  • Agreements, agreements, etc.

For instance, the Kyoto Protocol, Geneva Convention, Paris Treaty, etc.

     Private International Law 

    Also known as conflict of laws, private international law establishes and deals with the relationship between citizens and private entities of various nations. People come from various parts of the countries, and frequently they interact with one another to forge legal relations.

For instance, an Indian man and a Japanese woman were wed in India. If they ever decide they want a divorce, they will be compelled to go to either a Japanese court or an Indian court, depending on the requirements of private international law.

International Law Development:

We should study the history of international law if we wish to learn about how it has evolved. The earliest treaties and agreements are where the history of international law began. The 19th and 20th century accords alone did not create international law. Its practise dates back to antiquity. Lagash and Uma's peace treaties are regarded as the earliest examples of international law. Greeks laid the groundwork for the international legal system by creating the concepts of government and international relations.

Modern international law was established in European nations over a period of fifteen centuries. The European Renaissance was essential to the development of international law.

"This treaty recognised as the oldest and earliest boundary water treaty of the globe," states the pact between LAGASH and UMMA. Two Sumerian cities in Mesopotamia, Lagash and Umma, both possessed lush land that was irrigated by the Tigris water channel, also known as the Lum water canal. The maintenance of the canal was split between the two regions and the two cities.

On the condition that he would maintain the canal, Umma also used some of Lagash's fertile land for cultivation. However, after this agreement, Umma failed to maintain the canal and refused to maintain to pay Lagash's debt. Umma was diverting water upstream unilaterally. As a result, the canal was partially ruined.

As a result, Lagash and Umma engage in combat; Lagash, led by Enantive 2470 BC and Enmetena, ultimately triumphs over Umma. Following Umma's acceptance of Lagash's promises, the canal was repaired and water diverting was stopped.

The Treaty of Hudaybiyyah is regarded as the first treaty in Islam. The Treaty of Hudaybiyyah was signed when Muhammad, the founder of Islam, was a resident of Mecca. When the Prophet Muhammad and his 1400 hawkers left Mecca, the Quraishi tribe resisted them, but the Prophet did not use any force despite having 1400 hawkers.

He could have used their force, but Muhammad decided to sign a peace agreement, which lasted for 9 years, 9 months, and 9 days. This was the first peace treaty ever signed and is often referred to as the "Sulah Hudaybiyyah Treaty."

Purpose of the Agreement

The purpose of this agreement was threefold:

1. The Messenger of Allah would return to Medina that year rather than go to Mecca. In the coming year, Muslims will perform their yearly pilgrimage, and they will live in peace in Mecca for three days, extending into subsequent years, using only sheathed swords as their only weapons.

2. Both those who want to cooperate with the Quraish and those who want to form a commitment with the Prophet (Muhammad) would be able to do so. Any person who enters one of the parties is deemed a member of that party, and any aggression they are the target of is aggression against them.

3. Those who leave Mecca without the consent of their guardians and run to Muhammad will be returned to the Quraysh, but those who approach the Muslims will not.

Peace Treaty of Westphalia,1968

The Peace of Westphalia, 1968 is a group of treaties. The 30 years of conflict in Europe between 1618 and 1648 are related to the Westphalian Peace Treaty. After the peace treaty of Augsburg, religious strife spread over the entire Roman Empire, sparking the beginning of a 30-year conflict.

The Protestant union and the Catholic league engaged in a 30-year conflict. Habsburg Spain, France, and the protestant union included Norway and Denmark in the catholic league. The war began as a small-scale fight between Bohemia and the Holy Empire, but as time went on, other nations—including the Swedish and French—became involved, and eventually it enveloped all of Europe.

At the time, concepts like non-interference or peaceful coexistence were irrelevant. The purpose of war increasingly evolved as time went on to become political power and the balance of power in Europe. Catholic France received funding from protestant Sweden during the previous war, transforming the conflict that began for religion into one of political control. 18 lakh people had died in this war by the time the kingdoms understood that it was not in anyone's best interest to continue the conflict and that diplomacy and negotiation were viable alternatives.

And historians, lawyers, and political scientists began to consider better systems and relationships between nations and their sovereign powers. The Westphalia Congress's negotiations, which began in 1642 and lasted for 4 years, culminated in the signing of the treaty of Westphalia in 1648.
