The territory of this new European state is crossed by strategically important passes, the lowest in the entire Alps, leading from the Danubian basin to the Mediterranean (Italy). Thus, the Slovenes had been under cultural, civilizational and political domination of centers from these two parts of Europe until 1918. Because the mountainous land forms, dissected also by valleys and basins, were prone to processes of diffusion rather than fusion, the Slovenes became a national and political subject of their own as late as the nineteenth century. From 1918 to 1990 they were joined to Yugoslavia, a South-East European state, and learnt, to their cost, all the differences between the cultures of West and Central Europe on the one hand, and South-East and Eastern Europe and the Near East on the other. Hence the plebiscite decision by the nation for an independent state.
