Territorial disputes entail the serious risk of destabilising an international legal order. Given that many territorial disputes remain unsettled, a clarification of the rules governing the acquisition of territory should be crucial in international law. An essential issue of the international law of the acquisition of territory concerns the question of how one can strike a balance between the requirement of territorial stability and the need for taking account of changing situations involving territory. The concept of the historical consolidation of title, which will be examined in this article, provides a normative device to take account of temporal elements, that is, changing situations over time, in the process of the acquisition of territory. Thus the issue of the fundamental antithesis between stability and change vividly arises with regard to the concept of the historical consolidation of title. Thus, focusing on this antithesis, this study seeks to examine the concept of historical consolidation of title in the acquisition of territory. In particular, three issues must be examined: (1) features and criticisms of the concept of historical consolidation, (2) the relationship between the concept of historical consolidation and the Island of Palmas paradigm, and (3) the relationship between the concept of historical consolidation and the Burkina Faso/Mali paradigm. This article will reveal that the concept of the historical consolidation of title can be regarded as a corollary of the Island of Palmas paradigm. Given that the influence of temporal elements is unavoidable in the process of the acquisition of territory, the concept of the historical consolidation of title is in need of reassessment.

领土争端带来了破坏国际法律秩序稳定的严重风险。鉴于许多领土争端仍未解决，澄清有关获得领土的规则在国际法中应该是至关重要的。获得领土的国际法的一个基本问题涉及如何在领土稳定的要求和考虑涉及领土不断变化的情况的需要之间取得平衡的问题。本文将探讨的历史所有权合并概念提供了一种规范手段来考虑时间因素，即在获得领土的过程中随时间变化的情况。因此，关于所有权历史巩固的概念，稳定与变化之间的根本对立问题就生动地出现了。因此，本研究着眼于这个对立面，试图检验在领土获得过程中所有权的历史巩固概念。尤其需要考察三个问题：（1）历史整合概念的特征与批判；（2）历史整合概念与帕尔马斯岛范式的关系；（3）历史整合概念与帕尔马斯岛范式的关系。历史巩固和布基纳法索/马里范式。本文将揭示，所有权历史巩固的概念可以被视为帕尔马斯岛范式的推论。
