On 24 May 1918, the SNS called a meeting of its Executive Committee. Politicians of other Slovak movements were also present. The SNS expressed here that its aim was the self-determination of the Slovak nation. Participants of the meeting agreed on creating a common state of Slovaks and Czechs. On 12 September, the Slovak National Council was created (unofficially). The official creation happened on 30 October 1918 during a meeting, called by the SNS, in the town of Turčiansky Svätý Martin (today Martin). The SNS chairman Matúš Dula became chairman of the Council. This assembly of Slovak politicians also accepted the "Declaration of the Slovak nation" (also called "Martin declaration"), in which their will to politically join the Czech nation was expressed.
