In the first as well as in the second Yugoslavia, politics had a decisive influence on Slovenia's economic position in Yugoslavia. This was a consequence, firstly, of the economic area which merged only partly compatible economies. Secondly, it was because the economic model, or better, economic models were created on the basis of ideological and political patterns which allowed politics to govern economy. Thirdly, it was a consequence of the confrontation of national economies (three informal economies in the first Yugoslavia and six formal economies in the second), which fought for the most favourable and predominant position. In 1918, Yugoslavia was established for political reasons and it also disintegrated for political reasons and inter-national relations. The economies failed to reach the degree of autonomy which would allow the economic reasons to justify the political sense of existence of the Yugoslav state.
