MADOSZ was formally established on August 20, 1934 at Târgu Mureş. The party programme called for defending the peasantry from higher taxes, an end to abuses against grape-growers and loggers, a joint struggle with ethnic Romanian workers for the granting of specific demands, and respect for democratic rights and freedoms. Sándor Szepesi was its president from 1934 to 1937, while Gyárfás Kurkó held the post from 1937 to 1938. Other notable members included Imre Gál, Lajos Mezei, Ion Vincze and László Bányai. From April to November 1934, its official publication was "Székelyföldi Néplap" ("Gazeta populară din Ținutul Secuiesc" or "Popular Gazette of Székely Land").
