L. Oppenheim’s International Law. A Treatise. Volume 2 (of 2), part of a groundbreaking two-volume work, explores the legal structures regulating warfare, neutrality, and state relations during conflict. Published in the early 20th century, it addresses topics such as the behavior of belligerents, the control of blockades, the standing of neutral territories, and the handling of contraband and enemy property.
Oppenheim examines the dangers inherent in war, the legitimacy of the use of force, and the developing standards of humanity in combat, while tackling disputes such as the seizure of merchant ships and the legal limits of territorial control. The treatise highlights the conflict between state sovereignty and international legal limits, portraying war as both a requirement and an ethical challenge. Its thorough examination of the Hague Regulations and the relationship between politics and legal theory cements its status as a foundational work in the study of conflict law.
