Introduction to the Just War Tradition

The Just War Tradition is a key framework for ethical reflection on war and conflict. With roots in classical and theological thought, it continues to inform modern international law, military doctrine, and public discourse. But how do we decide when it is morally acceptable to go to war — and how wars should be fought?

In this self-paced course from King’s College London, you will explore the core principles of the Just War Tradition and how they are applied in contemporary conflicts. Led by Professor David Whetham, a renowned expert in military ethics, the course draws on historical, philosophical, and real-world examples, examining:

• The origins and philosophical foundations of Just War thinking

• The criteria for assessing the justice of going to war (jus ad bellum)

• Ethical considerations in the conduct of war (jus in bello)

• The emerging debates around justice after war (jus post bellum)

• How the Just War Tradition applies to real-world case studies and modern warfare

Through guided reflection and applied ethical reasoning, you’ll gain the tools to critically evaluate the legitimacy of military actions and the responsibilities of those who wage war.
