War, as one of the most devastating human acts, immensely impacts society, particularly its most vulnerable members - children. This paper explores the complex challenges faced by children in war circumstances and conveys the experiences and consequences war has on their development. Children in war are exposed to numerous harmful factors that can permanently affect their mental and physical health. The loss of home, and family, as well as limited access to education and health care, forces them to prematurely confront harsh living conditions. This work analyzes these conditions, focusing on psychological, social, and educational aspects, and investigates the transgenerational effect of war traumas. One of the key segments of the paper relates to providing tailored support and interventions, aimed at mitigating the negative effects of war on children. The importance of a multidisciplinary approach is emphasized, involving collaboration between educational institutions, healthcare facilities, government and nongovernment organizations, and the international community. Considering the comprehensiveness and complexity of this topic, the paper aims to raise awareness of the importance of mental health and emotional well-being of children in war-torn areas and to develop strategies and support programs that can help overcome trauma and build resilience.
