The word international law was used for the first time by the eminent jurist:

Jeremy Bentham coined the expression "international law" in An Introduction to the Principles of Morals and Legislation (printed 1780, published 1789), offering it as a clearer name for what had been called the "law of nations". Austin, writing decades later, is the tempting wrong choice: he discussed the subject but treated it as mere "positive international morality" because it lacked a sovereign's command. Pound and Salmond belong to a much later period.
