The term ‘national law’ is an umbrella term for laws recognized by a nation’s government. This type of law is a product of the law-making institutions of that nation, which may be the United States Congress, the French Parliament, or other bodies. Some states have a civil law tradition, whereas others have a common law tradition.

The idea that national law cannot be modified or overruled by another country’s laws is a wishful notion. Some have argued that national laws are incompatible with international law. This view has its critics, who argue that there is no such thing as a universal a-national law. The concept of natural rights has remained important for centuries, and they have gained more salience in the 20th century.

In a nutshell, the relationship between national law and international law is complex. Both systems help maintain international relations and the sovereignty of nation-states. In most cases, the relationship between national law and international law is harmonious, and the two systems work in synergy. However, it is important to note that the two systems should only be argued over if they conflict.

The concept of a nation state was established by the Peace of Westphalia, which established sovereign entities of equal size. Since 1648, the concept of a nation-state has grown in complexity. Originally, nation states were confined to the boundaries of a particular nation and were not subject to international regulation. However, today, nations and individuals can be subject to international law, requiring them to follow these laws.
