The SNS merged with Hlinka's Slovak People's Party – Party of the Slovak National Unity on 15 December 1938 and received no autonomous position in this party. This step was forced by the People's Party and supported only by a group of members around Miloš Vančo. Other members showed their disapproval during the meeting of the Executive Committee on 23 November 1938. However, after further talks with the People's Party, as well as the official stopping of the SNS's activities (by a government body), made the further existence of the party impossible.
