National holidays are important symbols of social unity. On April 23, 1921, the Turkish Grand National Assembly adopted the ’National Day, as the first day of the new Turkish State. The first day of April 23 started to be called with the children thanks to Himayei Etfal Society with the opportunity to collect aid activities on the ground of the National Day. Before April 1927; the first comprehensive Children's Day celebration began on April 23, 1927, although children's day was referred to by concepts such as ‘Children’s Day’ or ‘Children’s Holiday’. The celebrations developed in parallel with the desire to raise children who came to the republic. After the Second World War, the Democrat Party was founded thanks to Turkey's democratization efforts and the transition to a multiparty political life. In a single-party period, this unprecedented political movement resulted in the DP taking power in 1950. The political and social tensions in the country and the foreign policy events during the ten-year rule were shaped by the DP administration and these developments were reflected in the national festivals. The aim of this study is to discuss the celebrations of 23 April National Sovereignty and Children's Day held in the period of DP in comparison with the ceremonies held before in the case of İstanbul-Ankara and with the developing incidents of the period.
