The primary concern addressed in this research is the neglect of establishing a unified crisis management system in the Republic of Croatia. Through an analysis of the contemporary crisis management system in the Republic of Croatia, weaknesses in prevention, population protection, and response to harmful events are identified. The proposal suggests the creation of a separate institution in the form of the State Office for Crisis Management (DUKU) as an integral part of the homeland security system, marking a crucial step in upgrading the overall system. DUKU would assume a pivotal role in managing security threats, with a specific focus on responding to harmful events and crises. The implementation of these suggested changes is imperative for further strengthening and enhancing the crisis management system in the Republic of Croatia. This thesis envisions a fully integrated system that connects state institutions, operational forces, local communities, non-governmental organizations, and citizens, laying the groundwork for realizing the vision of developing an integrated crisis management system capable of coordinating and responding effectively during crises. The establishment of a central body like DUKU, equipped with a clear structure, authority, and resources, serves as the foundation for a faster, more efficient, and coordinated reaction involving all possible resources during crises. This approach aims to maximize the protection of lives, properties, and the overall well-being of Croatian citizens.
