In the article below the author reflects on the event of December 1, 1918 - The Great Union, which wrote a separate page in the history of Romanians. According to the study, the greatness of the event lies in the fact that although led by the political leaders, who wrote, explained, fought, it represents a historical fact of the entire Romanian nation, willed, lived and made aware. An important role played by the crystallization of national consciousness over time, which allowed the identification of all Romanians as a people, distinct through language, traditions, conscience, destiny, authentic national values, territory, faith and ideology. The study emphasizes that the national education system must be considered one of the priority areas, which, in fact, is and should be the main promoter of national identity and unity, culture and social welfare.
