The political-legal perspective of the development of the republics of the former SFRY can be obtained by a precise analysis of political developments in the former SFRY, viewed from the legal aspect, and under the influence of domestic and international factors that create a political reality in each individual republic. Building and taking care of a healthy, institutionally solid, legally dignified political system of one state is a challenge for every government, and therefore the government is a creator of an image of the political system, but also of innovative, economic, diplomatic, economic activity, which in many ways determines the level of democracy, the standard of living , the degree of political culture, constitutional and legal progress, the development of local self-government, and thus forms the image of a given society viewed through the lens of the political system. After its creation, the SFRY was a supranational state, with a federal political system, formed on the ruins of the outdated monarchist form of government, it had the futuristic contours of a real reality and, per its ideological concept, was significantly ahead of the time in which it existed. It was a symbol of sociological progress, synonymous with concepts that modern authors of political-legal thought today call cosmopolitanism. In this paper a comparative method of research will be applied, and based on it, will be presented the key determinants that define the social situation in the republics of the SFRY today, altogether with the proposals for the implementation of positive experiences, as well as the proposals for overcoming the potential difficulties of certain republics that they are facing today, considering that they have successfully overcome other similar obstacles.
