The author studies the 19th-century Slovak National Movement as a manifestation of the ethos of plebeian resistance against the “laws of progress” of the century in question, according to which small ethnic groups and nations were to be assimilated for the sake of the further development of more advanced nations and their cultures. A significant role in the formation of the ethos of plebeian resistance was played by Slovak folk culture, the historical context of Great Moravia, the solidarity and support of other Slavic nations living in the Habsburg monarchy, and, above all, the moral qualities of Slovak patriots. Among the most significant manifestations of this ethos was the codification of Slovak, which contributed to the formation of Slovak national identity and national ideology, the 1848–1849 Slovak Uprising, and the development of the Slovak national movement in the 1860s continuing into the mid-1870s. The aim of the 19th-century Slovak national movement was to achieve an equal position of the Slovak ethnic group among the other nations and ethnic groups living in the Habsburg monarchy, which would give rise to the free development of its creative powers and abilities as well as to the pursuit of ethical, humanistic ideals in the lives of its members.
