Just as the overall development of the Republic of Croatia was marked by discontinuity and numerous interruptions also developed local government. In the tradition of local government involved historical reminiscences from the medieval period, Germanic - Austrian and Hungarian traditions from the period of Austro-Hungarian Empire until the oneparty experience with a comprehensive system of self-management socialist Yugoslavia. Croatian independence came to the reaffirmation of local government where there was a strengthening of the central institutions, which resulted in the centralization contributed by Patriotic War. It was not until year 2000 constitutional change followed significant progress in decentralization and only then created opportunities for stabilization of local institutions such as local government units, local executive bodies, administrative organizations and etc... Local units are the most important local institutions and therefore distinguish the city, municipality and county. The task of the city as the local unit is its effect on the principle of the rule of law and protection of citizens' rights. It is also required to build its capacity to act. Necessary were rational solutions in terms of personal staff, structures managers etc. Without them we wouldn’t be able to create more economical, more efficient and effective development of the city and other forms of local self-government for the benefit of citizens. And at the end of each unit of local government must be as largely focus on social values. This would stabilize the country, solved the public problems and would allow the development of the country in the system of the European Union.
