Human society has always had a certain type of organization whose task would be to maintain order in society and protect its core values. In response to these needs, a police service was established. In the Republic of Croatia, a modern police service provides citizens with protection of their constitutional rights and freedoms and protection of the other by the Constitution of the Republic of Croatia protected values. It consists of three main organizational units: police directorates, police administrations and police stations. Police administrations are established for the purpose of performing police and other affairs in the territory of the Republic of Croatia; are divided into four categories, and in the territory of the Republic of Croatia there are 21 police administrations. The boundaries of the county are at the same time the boundaries of the local jurisdiction of the police administration. The organization of the police administration includes the organizing bodies and services: Chief of Police Administration, Chief of Office, Operational Communication Center, Police Service, Criminal Police Service, Border Service, Administrative and Inspection Services, Legal, Financial and Technical Affairs Services. Employees in police administrations are police officers. They, in accordance with the relevant regulations, must perform their work in a conscientious and responsible manner.
