The article addresses the issue of the resilience of Ukrainian society functioning under conditions of a prolonged armed conflict. The aim of the study was to identify and analyze the factors influencing the level of social resilience in Ukraine during wartime, with particular emphasis on social, organizational, and psychosocial aspects. The research process employed theoretical methods, including analysis, synthesis, and inference, based on domestic and international scientific literature as well as reports concerning social security and the functioning of societies under conditions of armed conflict. The results of the study indicate that despite numerous military threats and extensive infrastructure destruction, Ukrainian society demonstrates a high level of adaptive capacity, social solidarity, and self-organization. An important role in strengthening social resilience is played by the efficiency of state institutions, the development of civil society, effective crisis communication, and the informational resilience of society. The obtained results allow the conclusion that social resilience constitutes one of the key elements of state security in the context of contemporary threats and armed conflicts. Ukraine’s experiences may provide an important source of knowledge for other countries in the field of building social resilience, crisis preparedness, and counteracting the effects of contemporary security threats.
