The question of what constitutes a ‘state’ is fundamental to the study of political science and international relations. States are the primary actors on the world stage, and the process by which an entity achieves statehood is governed by principles of international law and shaped by political reality. Two principal theories have emerged to explain this process: the declarative and the constitutive theory. This essay will examine the declarative theory of statehood, outlining its core criteria and discussing its application and limitations in the context of international politics.
The declarative theory posits that the existence of a state is a matter of objective fact, independent of recognition by other states. According to this view, an entity becomes a state as soon as it meets a set of predetermined legal criteria. The most widely accepted articulation of these criteria is found in Article 1 of the Montevideo Convention on the Rights and Duties of States (1933). This convention, though originally a regional American treaty, is widely regarded as reflecting customary international law on the matter (Shaw, 2017). Article 1 stipulates that for an entity to be considered a state, it must possess four qualifications: (a) a permanent population; (b) a defined territory; (c) a government; and (d) the capacity to enter into relations with other states. The presence of a permanent population and a defined territory are relatively straightforward factual requirements, although border disputes do not necessarily negate a state's existence. The requirement of a government implies the existence of an effective political authority capable of exercising control over the territory and population. Finally, the capacity to enter into relations with other states refers to legal and political independence from external control (Crawford, 2006). The core idea is that if these conditions are met, the entity is a state in law, whether or not other states have formally acknowledged it.
This approach stands in direct contrast to the constitutive theory of statehood. The constitutive theory argues that an entity only becomes a state through the act of recognition by other, pre-existing states. In this view, recognition is a precondition for statehood, not merely an acknowledgement of an existing fact. While the declarative theory emphasises objective criteria, the constitutive theory highlights the subjective and political nature of state creation, where membership of the international community is granted by its current members (Grant, 1999). This makes statehood contingent on the political will of powerful nations, rather than on the empirical reality of the entity seeking state status.
However, the application of the declarative theory is not as straightforward as it might appear. While it is the prevailing theory in legal doctrine, international practice often demonstrates the crucial importance of political recognition. There are several entities that appear to satisfy the Montevideo criteria but are not universally accepted as states because they lack widespread recognition. A prominent example is Taiwan (Republic of China), which has a permanent population, a defined territory, a stable and effective government, and conducts foreign relations, yet its status as a sovereign state is contested by the People's Republic of China and, consequently, it is not recognised by the majority of states or the United Nations. Similarly, the case of Palestine demonstrates that even with significant international support and the satisfaction of many declarative criteria, full statehood remains contested due to political opposition. These examples suggest that in the real world of international politics, the legal objectivity of the declarative theory is often overshadowed by the political realities central to the constitutive theory.
In conclusion, the declarative theory provides a clear and objective framework for defining a state based on the four criteria laid out in the Montevideo Convention. It asserts that statehood is a question of fact, not of political consent. However, while this theory is legally dominant, its practical application reveals significant limitations. The political act of recognition by other states remains a powerful, and often decisive, factor in determining an entity's ability to function as a state on the international stage. Therefore, while the declarative theory explains the formal requirements for statehood, it does not fully capture the complex interplay of law and power that governs the creation and acceptance of new states in the international system.
