On October 17, 1958, the Peasants' Party of Turkey merged with the Republican Nation Party to form the Republican Peasants' Nation Party (Cumhuriyetçi Köylü Millet Partisi - CKMP). On June 12, 1960, following the May 27 coup d’état, the junta, dubbed the "National Unity Committee", dissolved the parliament and on June 13, closed the district organizations of all political parties. In 1961, when the civil parliamentary system was once again in effect, on October 15, general elections were held, at which the Republican Peasants’ Nation Party received 14% of the votes to emerge as the third party and win 54 seats in the parliament and 16 senators. When the Justice Party emerged victorious at the 1963 elections, Osman Bölükbaşı, together with 28 MPs, resigned from CKMP to establish once more the Nation Party and be elected its president.
