In 1922, the SNS demanded cultural and administrative autonomy in the "Memorandum of the SNS". In the 1925 general elections, the party received 35 432 votes and no mandates in the National Assembly. In another election year, 1929, the party participated in the elections as a member of a multi-ethnic coalition of parties (Czechoslovak National Democracy, SNS and an ethnic Russian block), which received 359 547 votes and 15 mandates. Only one mandate belonged to the SNS. On 16 October 1932, leaders of the SNS and the Hlinka's Slovak People's Party Martin Rázus and Andrej Hlinka accepted the "Zvolen manifesto", in which they rejected Czechoslovakism. Here they formed an alliance of their parties called the Autonomy Block. A group of SNS members (e.g. M. Daxner, Ján Paulíny-Tóth) didn't agree with this coalition. Until the election in 1935, other political parties also joined the Block. The Autonomy Block succeeded in the parliamentary election: receiving 30.12% of the Slovak votes, it became the winner of the elections in Slovakia.
