The concept of precursor refers to the factors that emerge before a situation, event or development and lead to its occurrence or prepare the ground for it. In this context, this concept indicates how important past developments in international relations play a critical role in understanding current and future events. Examples of where the concept of precursor is used include wars, analytical use, diplomatic agreements and political and economic contexts.
