War was officially made illegal on August 27, 1928, with the signing of the Kellogg-Briand Pact. This landmark agreement marked a significant attempt by world powers to renounce war as an instrument of national policy.
The Kellogg-Briand Pact: A Landmark Attempt to Outlaw War
The Kellogg-Briand Pact, formally known as the General Treaty for Renunciation of War as an Instrument of National Policy, was a multilateral agreement signed in Paris, France. It was primarily sponsored by Frank B. Kellogg, the U.S. Secretary of State, and Aristide Briand, the French Foreign Minister. The pact committed signatory nations to abstain from using war as a tool for resolving disputes between countries.
Key Provisions and Global Impact
The core principles of the Kellogg-Briand Pact were designed to foster a new era of international peace:
- Renunciation of War: The primary aim was the outlawry of war, with nations agreeing to "renounce war as an instrument of national policy in their relations with one another."
- Peaceful Dispute Resolution: Signatories pledged that the settlement or solution of all disputes or conflicts, no matter their nature or origin, should "never be sought except by pacific means."
- Widespread Adoption: Initially signed by 15 nations, including major powers like the United States, France, the United Kingdom, Germany, Italy, and Japan, the pact was eventually ratified by 62 nations. This broad acceptance underscored a global desire to prevent future conflicts after the devastating experience of World War I.

Historical Context and Subsequent Challenges
The Kellogg-Briand Pact emerged from a period of intense internationalism and a strong yearning for peace following the immense destruction of the Great War. It represented an idealistic effort to create a legal framework that would make armed conflict obsolete.
However, the pact faced significant limitations:
- Lack of Enforcement Mechanisms: A critical flaw was the absence of clear enforcement provisions or penalties for nations that violated its terms. It did not define what constituted "war" and made no explicit provisions for self-defense, which was implicitly understood.
- Failure to Prevent Major Conflicts: Despite its noble intentions, the Kellogg-Briand Pact ultimately failed to prevent major subsequent conflicts, notably World War II. Aggressive nations largely ignored its principles, demonstrating that a legal declaration alone was insufficient without robust enforcement.
Legacy and Influence on Modern International Law
Although the Kellogg-Briand Pact did not immediately achieve its goal of ending all wars, its influence on the development of modern international law is undeniable and profound.
- Foundational Principle: It established the crucial principle that aggressive war is illegal under international law. This concept became a fundamental building block for future international legal frameworks concerning peace and security.
- Nuremberg Trials: The principles embedded in the Kellogg-Briand Pact were referenced during the Nuremberg Trials after World War II, where aggressive war was prosecuted as a "crime against peace," marking a significant step in holding individuals accountable for initiating such conflicts.
- United Nations Charter: The United Nations Charter, adopted in 1945, built upon the foundation laid by the Kellogg-Briand Pact, but with significantly stronger enforcement mechanisms. Article 2(4) of the UN Charter explicitly prohibits the threat or use of force against the territorial integrity or political independence of any state, with specific exceptions for self-defense (Article 51) and actions authorized by the UN Security Council.
Comparison: Kellogg-Briand Pact vs. UN Charter
The evolution from the Kellogg-Briand Pact to the UN Charter highlights the international community's ongoing efforts to legally constrain and prevent armed conflict.
| Feature | Kellogg-Briand Pact (1928) | UN Charter (1945) |
|---|---|---|
| Core Principle | Outlawry of war as an instrument of national policy | Prohibition of the threat or use of force (broader than just "war") |
| Enforcement | No explicit enforcement mechanisms or penalties | Comprehensive collective security system via the UN Security Council, including sanctions and authorized use of force |
| Exceptions | Implied right to self-defense | Explicit right to individual and collective self-defense (Article 51) |
| Scope of Prohibition | Renounces "war" | Prohibits "threat or use of force" (more comprehensive, covering various forms of aggression) |
| Impact on Law | Established the illegality of aggressive war | Created a robust legal and institutional framework for maintaining international peace and security |

In conclusion, while the aspiration of the Kellogg-Briand Pact to eliminate war was not fully realized, its signing on August 27, 1928, marked a pivotal moment in establishing the legal illegality of war and paved the way for more comprehensive international legal frameworks aimed at preventing conflict.
