As in all other societies in the world, Turks have held events such as commemorations, celebrations and holidays depending on the political phases, traditions, lifestyles, beliefs and geographical factors throughout their history, and they have continued to transfer a large part of them to future generations. They enriched their cultural life, which they founded in their first homeland, Central Asia, with new cultural values with migration to Anatolia and conversion to Islam. During the period of the Ottoman Empire, they started to practice many ceremonies and rituals required by the empire Parallel to the developments in the West, the symbols and ceremonial activities required by the Nationalism, which started to be effective in the world after the French Revolution, were built on Ottomanism in the first place However, II. From the Second Constitutional Era, with the bankruptcy of Ottomanism and the disintegration of the empire, Turkism came to the fore. The rulers of the period took as an example the announcement of the "National Holiday" day, which has become widespread in the West for a while and strengthened nationalism, within some practices aimed at the development of Turkish nationalism. The rulers of the period took as an example the announcement of the "National Holiday" day, which has become widespread in the West for a while and strengthened nationalism, within some practices aimed at the development of Turkish nationalism. In this context, the day when the Constitutional Monarchy was proclaimed began to be celebrated as the first national holiday in our history, and other than today, celebrations such as the founding day of the Ottoman Empire and the training, workers and children's holidays were held. In the Republican period, this practice, which started with the declaration of the day of the opening of the Grand National Assembly of Turkey as a holiday while the National Struggle was still going on, continued with the proclamation of the Republic being celebrated as an international "national holiday" through the consulates. Celebrating Atatürk's departure to Samsun, the day when the Great Offensive was won, and the day when the Turkish Grand National Assembly was opened, which are known as important days during the National Struggle period, were also determined as the Children's Day and have been continued until today. The Republic Day celebrations, which are the subject of the study, started officially in 1925, and the 10th, 50th and 75th Anniversary celebrations were more elaborate and detailed than the others. Especially the 10th Anniversary celebrations are the most permanent. While the celebrations generally continue with similar ceremonies starting from the first, it is seen that the characteristics of each period, the political events of the period, the issues and discussions in domestic and foreign politics have a significant impact on the feast celebrations. Especially in the process that started with the transition to multi-party-political life, it is seen that Turkey's national holiday was overshadowed by the conflicts between the government and the opposition. In addition, factors such as terrorist incidents and economic troubles were also important reasons that negatively affected the enthusiasm and participation of the National Holiday.
