If someone had sighed at the beginning of the 19th century that a unified German state would be formed in some time and Italy would able to unite itself, that one would certainly concerned to be a fool. Yet these ideas were realized in full around the year 1870. Few, however, realized that the 19th century by the accomplishing those political goals Europe came to a state that reminds the dearest dreams of the ideologists of the year 1000, who put forward a concept of European political arrangement built as an imaginary Tetrarchy consisting of 4 equal provinces Galia, Germania, Roma and Sclavinia. As it is clear, Sclavinia of these provinces, is still missing. The presented article attempts to give an overview of the implementation of the „Sclavinia project” with the assignment of its other names, such as Intermarium, throughout history. Martin Homza demonstrates this on mutual Slovak-Polish relations, which considers the basic axis of this possible construction. Methodologically, these relations divids into 4 subcategories according to the strength and weakness of their bearers: Relation: Strong: Strong; Weak: weak; Weak: Strong and Strong: Weak.
