FAQ
Frequently Asked Questions
Yes, in meaning, but 'law of nations' is the older, more formal, and historically/philosophically loaded term. 'International law' is the standard modern term for current practice and positive law.
Historically, it governed states. However, modern developments, particularly in international criminal law (e.g., crimes against humanity), have extended its reach to individuals in certain contexts.
Key figures include Hugo Grotius (Dutch), often called the father, along with Alberico Gentili (Italian) and Emer de Vattel (Swiss). Their works systematized the customs and principles between states.
The term 'international law', coined by Jeremy Bentham in the 18th century, gradually replaced 'law of nations' as it was seen as more precise for the modern state-centric system, moving away from natural law connotations.
