the territory of present-day Croatia (including the Military Frointaire and Dalmatia). To accomplish this, the ground had to be prepared, so that diplomacy and the military would have a stronger base for taking action. The bases for this was the Serbian state law, and where it wasn't possible to appropriate the land with it, the argument of nationality, and when that argument couldn't be applied, then it was necessary to "create" the Serbs among the target population, if not among all, then among the majority. The main target were Orthodox Christians in the neighboring, non-Serb countries. In 1848/50, Serbian government organized a secret network of agents who propagated the Serbian ideas. Those agents were concealed as cultural workers. The famous agents were Georgije Nikolajević and Stjepan Mitrov Ljubiša. The 'creation' of new Serbs was carried out by identification of Orthodox Christianity in Croatia and Bosnia and Herzegovina only with Serbs. Another argument used in the areas with no Orthodox Christians was identifying people who spoke Shtokavian with the Serbs. The idea "all Shtokavians are Serbs" was created by German Slavists in the 1850s, and was promoted by the Austrian government who wanted to equalize Croats and Serbs so that it could more easily rule the Croatian lands and in the next stage conquer Serbia and penetrate across Macedonia to Thessaloniki. The idea was that it was easier to "govern Belgrade and Zagreb if the same language was spoken in them". Geostrategic position of Belgrade in relation to Zagreb further contributed to favoring the Serbs whom Austrians did not perceive as a danger, unlike Croats who had own language, politicians, national consciousness, laws, military tradition and prepared army, as well as international treaties which have affirmed their rights, so Austrians needed someone (Serbs) to discipline the Croats. The same was done by Hungary which became a strong political factor after 1848 and that wished to expand into the Southeast Europe, which was particularly strong during the reign of Károly Khuen-Héderváry over Croatia. The revolutionary 1848 and the process of building a modern Croatian nation resulted in closer co-operation between Croats and Serbs and recognition of their equality in the sense of Illyrian Movement (also known as the Croatian National Revival) and Yugoslavian ideas. In the 1830s, ideas of the Illyrian Movement spread to Dalmatia. In 1835, Božidar Petranović began publishing the Serbo-Dalmatian Magazine. In the following thirty years, Croats and Serbs
