One of the most important challenges every country faces is the ability to respond to the changing political environment. History provides enormous material in this regard, which is eagerly used by scholars, for example, in the discourse on conflicts and wars. In this respect, the course of the Byzantine-Arab conflict in the tenth century is particularly worth mentioning. In this text, the author attempts to identify the mechanisms of reforms in the administrative and military spheres that allowed the Empire to avert a crisis on its eastern borders and, over time, go on the offensive. Due to the specificity of the field of knowledge, the dominant research method was source confrontation and discussion with the literature on the subject. This text is divided into several parts, including the introduction, the part devoted to administrative reforms, the part relating to reforms in the functioning of the army (general remarks, discipline, battle preparation, aftermath instructions, preferences regarding the selection of commanders) and the summary. It appears that the reforms implemented by the Byzantine Empire were deliberate and resulted in averting the Arab threat in the tenth century.
