The author examines Ľudovít Štúr (1815–1856), the main representative of the Slovak national movement in the 1840s, and his personal ethos in the struggle for the rights and freedom of the Slovak ethnic group. Štúr paid great attention to the development of the ethnic, social, and political awareness of Slovaks. In this effort, the Slovenskje národňje novini (Slovak National Newspaper) played an important role, through which Štúr and the representatives of the Slovak national movement shaped and spread its social and political program, the aim of which was both the fight against the national oppression of the Slovaks, but also the achievement of equal rights for the Slovak ethnic group in Hungary and the Habsburg Monarchy.
