Balthazar Ayala

Natural Law and International Law Founders

Balthazar Ayala (1548 to 1584) was a jurist from the Habsburg Netherlands who specialized in the law of war. Trained at Leuven, he served as auditor general of the Army of Flanders from 1580 and later as master of requests in the Great Council of Mechelen. His 1582 treatise De jure et officiis bellicis et disciplina militari became a foundational text of early international law, republished in 1597 and later translated for the Carnegie Institution Classics of International Law series.

FAQs

What made Balthazar Ayala's treatise on the laws of war distinctive?

It combined the laws of war, the duties of war and military discipline, and focused on legality rather than morality.

A KU Leuven research project calls Ayala's De iure et officiis bellicis et disciplina militari libri tres both unique and radical. Ayala combined three literary traditions, the laws of war, the duties connected with war and military discipline, to lay the foundations for a new perspective on the laws of war and peace. The project also notes that his focus on legality rather than morality was a radical departure from his theological precursors.
