This plan was kept secret until 1906 and has been interpreted by some as a blueprint for Serbian national unification, with the primary concern of strengthening Serbia's position by inculcating Serbian and pro-Serbian national ideology in all surrounding peoples that are considered to be devoid of national consciousness. Because "Načertanije" was a secret document until 1906, it could not have affected national consciousness at the popular level. However, some scholars suggest that from the second half of the nineteenth century to the outbreak of World War I, “leading political groups and social strata in Serbia were thoroughly imbued with the ideas in the Nacertanije and differed only in intensity of feeling and political conceptualization”. Political insecurity, more so than Yugoslavism or Serbian nationalism, appeared to be the prevailing reasoning behind the idea of expanding Serbian borders. The document is one of the most contested of nineteenth-century Serbian history, with rival interpretations. Some scholars argue that Garašanin was an inclusive Yugoslavist, while others maintain that he was an exclusive Serbian nationalist seeking a Greater Serbia.
