He expressed confidence in the Russian Empire however, as it was the only country of Slavs that was not dominated by anybody else, yet it was one of the most powerful nations in the world. He often symbolized Slavs as being a tree, with "minor" Slavic nations being branches while the trunk of the tree was Russian. His Pan-Slavic views were unleashed in this book, where he stated that the land of Slovaks should be annexed by the Tsar's empire and that eventually, the population could be not only Russified, but also converted into the rite of Orthodoxy, religion originally spread by Cyril and Methodius during the times of Great Moravia, which served as an opposition to the Catholic missionaries from the Franks. After the Hungarian invasion of Pannonia, Hungarians converted into Catholicism, which effectively influenced the Slavs living in Pannonia and in the land south of the Lechs.
