The Right of Conquest
Defining the Principle
Historically, the "right of conquest" referred to a principle of international law that granted ownership of territory acquired through military force. This doctrine recognized the immediate possession of land achieved by arms as a legitimate basis for sovereignty. However, its significance has progressively diminished, particularly following World War II, with the advent of concepts like "crimes against peace" and the subsequent codification of international norms.
Erosion in International Law
The United Nations Charter fundamentally altered the landscape by prohibiting the threat or use of force against the territorial integrity or political independence of any state (Article 2, Paragraph 4). Nations resorting to force since the Charter's inception have typically invoked justifications such as self-defense or collective defense, rather than conquest.[1] This shift reflects a global move away from territorial acquisition through military means.
Historical Trajectory
Proponents' Rationale
Advocates of the right of conquest argued that it acknowledged the prevailing status quo. They posited that denying this right was futile unless one possessed the military capability and willingness to enforce such a denial. Furthermore, it was traditionally accepted that a conquering force, by definition stronger than the previous governance, was better positioned to establish peace and stability. Thus, the right of conquest served to legitimize the conqueror's rule towards this end.[citation needed][not verified in body]
Decline and Disestablishment
Several key developments contributed to the decline of the right of conquest. The extensive colonial annexations, such as the Scramble for Africa, the immense destruction of World War I and World War II, and the alignment of major powers like the United States and the Soviet Union with the principle of self-determination, all played significant roles. Formal international law progressively dismantled this principle through instruments like the Kellogg-Briand Pact (1928), the post-war Nuremberg and Tokyo Trials, the UN Charter, and the UN's role in decolonization.[citation needed]
Arguments & Justifications
The Logic of Power
The core argument for the right of conquest rested on the premise that military success demonstrated superior strength, which was seen as a practical determinant of political reality. Proponents believed that acknowledging this reality facilitated stability by establishing a clear, albeit forceful, transfer of authority. The implication was that a successful conqueror was better equipped to govern and maintain order than the preceding regime, thereby serving the interests of the populace.
Legal Frameworks
The UN Charter's prohibition on the use of force remains a cornerstone of modern international law. While nations may invoke self-defense, the acquisition of territory through aggression is widely condemned. Despite these legal prohibitions, contemporary geopolitical events continue to fuel debate regarding the potential re-emergence or reinterpretation of conquest-related principles due to enforcement challenges.[2][3]
Conquest & Occupation
Pre-1945 Legalities
Prior to 1945, the transfer of territory acquired through conquest was governed by the laws of war. This process typically involved military occupation followed by a peace settlement. While a formal peace treaty was not always strictly necessary to validate a title acquired by conquest, it served to solidify any defects in the title. Crucially, the consent of the dispossessed state was not a prerequisite for the acquisition of rights by the conqueror.[4][5] However, conquest undertaken outside of declared warfare was considered illegal.
Post-War Realities
In the post-World War II era, the nature of territorial acquisition shifted. Many conflicts concluded with armistices rather than peace treaties, leaving territorial statuses in a state of legal ambiguity. The Korean War, for instance, concluded with an armistice, meaning the involved parties remain technically at war. This departure from traditional peace settlements highlights the evolving, and often contentious, application of international law concerning territorial control.[6]
