The following study deals with the activities of Christian Social Workers' organizations and Christian trade union movements operating in Slovakia in the first half of the 20th century. The Social Democratic Party of Hungary had gained a dominant position in the trade union movement in Hungary. Discrepancies between the Slovak Social Democrats and Catholic priests were weakened by their common interest in improving the social status of the Slovaks. The Social Democrats also became the strongest political group in the First Czechoslovak Republic.
