Police organizational structures are one of the most important factors of organization and management within the Croatian police. The organization is based on the achievement of set goals, but at the same time, it takes into consideration proper management and pays close attention to the staff. By doing so, it achieves a social benefit for the citizens. This shows how well the police organizational structure in the Republic of Croatia is arranged. The police is definitely one of the main and one of the oldest social institutions whose main tasks are to maintain public peace and order and to protect the citizens, their freedoms and their constitutional rights. The police organizational structure is set up in such a way that the Ministry of the Interior and the Police Directorate represent the two most important governing structures within the Croatian police. They issue the main provisions and regulations, which give the competent police administrations i.e. police stations the authority to enforce all the prescribed tasks within their jurisdiction. One of the most important tasks is that they cover and protect the entire territorial scope of the Republic of Croatia and its maritime and land borders, but also, even more importantly, they protect the citizens and all those within its borders. The Croatian police have a great history. It all began in the early 1990s when they were among the first ones to defend the homeland and the territories of the Republic of Croatia. Today, after a complete construction and systematic upgrading of the organizational system, the Croatian police has become one of the best organizational police systems in Europe.
