This work contains a short description of the incidence of the Croatian border police in the context of the European administrative territory, that is the work that the border police and the border police officers do in order to protect the state border and its integrity, also the work that the border police do inside the country's territory in order to maintain a peaceful status for the safety of assets and citizens of the Republic of Croatia.The Ministry of internal affairs' structure is shown in which, according to the Act of internal structure of the Ministry of internal affairs, as an administrative organisation, there are constituted the Independent sector for the Schengen coordination and EU projects and the Police Directorate. The Border office is organised inside the Police Directorate which is responsible for the incidence of the border police. The police officials and the jurisdiction of the police are stated in the work to show the role of the police in society.Maintaining internal safety today is not only a national duty, it has become a European or even a global problem. By describing the duties of the border police, the importance of the border police measures on the state border have been highlighted such as stopping criminal acts in the territory of the Republic of Croatia and the illegal entrance of foreigners which have a major role in the total measures that effect keeping the safety.The measures conducted by the police on the state border can be more efficient if they are coordinated with the neighbouring and other countries' police and connected and supplemented with measures that other bodies of supervision and control conduct in controlling the migration and residence of foreigners in the country. By joining the EU, many regulations have changed in the Republic of Croatia which directly influences the work of the border police, therefore the execution of the Integrated border management needs to specialise the border police with the cooperation of Frontex.
