1.Before the Communist Party of Vietnam was born, there were activities to propagate proletarian ideology, associated with the great contributions of leader Nguyen Ai Quoc.^[1], including the role of patriot Nguyen An Ninh^[2]When the Vietnam Revolutionary Youth Association was established in 1925, the content of ideological and propaganda work was promoted a step further (although that concept did not yet exist). The Association's Charter clearly stated that the Party's work included committees such as: Secretariat, Communications Committee, Propaganda Committee, Organization Committee, Finance Committee, Agriculture Committee, Industry Committee, Military Committee, Education Committee, and Women's Committee.^[3]. Thus, it can be consideredPropaganda DepartmentandBoard of EducationThe Association is the predecessor of the propaganda department of our Party.

Before becoming the ruling party, in the process of leading the revolution, the basic and urgent task at that time was to propagate, educate, and mobilize cadres, party members and people to know, understand, believe and actively act according to the Party's political platform and revolutionary line; constantly propagate to make the proletarian ideology increasingly ingrained and rooted in Vietnamese social life. Therefore, when our Party was first established in February 1930, it established the Agitation and Propaganda Committee, later changed to the Ministry of Propaganda (October 1930), the Ministry of Propaganda and Agitation (1934)... From 1930 to 1945, although the names were different, they were all advisory bodies, assisting the Party Central Committee in ideological work (propaganda).

When becoming the ruling Party, it requires comprehensive leadership in all fields, accordingly, it is necessary to carry out many Party tasks, such as: Ideological work, cultural and artistic work, science and education work, foreign affairs work, economic work, mass mobilization work... To ensure comprehensiveness and depth, our Party has established a staff and support apparatus, with each field of work often having a corresponding organizational apparatus, often called Party committees. However, to ensure a streamlined apparatus, many tasks are assigned to a responsible agency.

2.In the history of our Party, up to now, the term propaganda has been used twice as the name of a Party staff agency, and accordingly, the term propaganda work was born, existing to this day.

The first timeIn 1959, according to Decision No. 91-QD/TW dated December 1, 1959 of the Secretariat on merging the Central Propaganda and Education Committee and the Central Cultural Education Committee into the Central Propaganda and Education Committee, abbreviated asCentral Propaganda Department.By 1968, according to Decision No. 1584-QD/TW dated January 30, 1968 of the Politburo on dividing the Central Propaganda Department into two departments:Propaganda DepartmentyesCentralandCentral Committee for Science and Education. The conceptual content of propaganda work during this period does not completely coincide with the conceptual content of propaganda work today.

Second timeis from 2007 to present, according to Decision No. 80-QD/TW dated August 28, 2007 of the Politburo on the functions, tasks, and organization of the Central Propaganda Department, on the basis of merging the Central Ideology - Culture Department and the Central Science and Education Department. However, the propaganda work in this period has new content, with broader connotations than the previous period.

Propaganda work today includes many fields and activities. In terms of propaganda work, people often mention the following contents: Consulting on the issuance of leadership and direction documents; guiding and organizing the implementation of guidelines, policies and strategies; urging, inspecting and supervising the implementation; summarizing, concluding and evaluating the implementation. In terms of propaganda activities, people often pay attention to areas of activity such as: Researching and educating political theory; protecting the Party's ideological foundation; orienting propaganda and education on Party History; studying and following Ho Chi Minh's ideology, morality and style; activities of reporters, oral propaganda, visual agitation; orienting and directing press - publishing, culture - arts; researching, investigating and orienting public opinion; scientific work (science, technology, environment, education, training, vocational training, healthcare, physical education, sports, population, family, children...); foreign information, international cooperation...

The scope of propaganda work currently includes vertical sectors in the sense of leadership work of Party committees at all levels (Central Propaganda Department, Provincial/City Party Committee Propaganda Department; District/County, City Party Committee Propaganda Department; Commune, Ward, and Town Party Committee Propaganda Department), propaganda work in the Fatherland Front, socio-political organizations, in the armed forces, schools, agencies, units...

3.In February 1930, the Communist Party of Vietnam was born, establishing the Agitation and Propaganda Committee.^[4]. A few months later, the Propaganda and Education Committee issued a document“General propaganda of International Red Day August 1st"^[5],condemning imperialist war, calling for anti-imperialism, anti-oppression, anti-exploitation, anti-aggressive war, protecting peace, protecting the Soviet Union; raising high the slogan: Indochina is completely independent! Establish a workers' and peasants' government! Confiscate all land of local and foreign landlords and distribute it to the peasants! Long live the Communist Party! Long live the Indochina revolution!...^[6]. At the end of that document it says: "Published by the Communist Party's Propaganda and Agitation Department in 1930"^[7]. This is the only, earliest document that remains to this day that clearly states: Published by the Propaganda and Agitation Department of the Communist Party of Vietnam.

The publication of that document caused a great deal of public opinion in contemporary society and had a great encouragement for the masses of workers and peasants in our country to rise up to fight against imperialist war, protect the Soviet Union, and support the national liberation movement in the world. From August 1 to October 1930, hundreds of rallies and demonstrations of our people against imperialist war broke out throughout the country. Since then, August 1 has become a major milestone in the history of our people's revolutionary struggle under the leadership of the Party, associated with the birth of an extremely valuable historical document, marking a very meaningful activity in the history of the Party's propaganda sector.

Based on these documents and historical events of special significance, in 2000, the Politburo (VIII tenure) decided to take August 1 every year as the Party's Traditional Day of Ideological and Cultural Work. On August 28, 2007, the Politburo issued Decision No. 80-QD/TW to merge the Central Ideological and Cultural Committee and the Central Science and Education Committee, establishingCentral Propaganda DepartmentIn the same year 2007, the Central Party Secretariat (10th tenure) decided to take August 1st of each year as the traditional day of the Party's Propaganda sector.

The traditional day of the Propaganda sector has profound political, ideological and cultural significance, representing a historical milestone marking the birth and maturity of the Party's propaganda work - the field with the earliest history in the Party's leadership activities, affirming the primary importance of ideological work. This is a very important component in the Party's leadership activities, a key field of Party building work in terms of politics and ideology, "the soul of all Party work".^[8], has a great influence on the leadership of the government and organizations and unions in the political system. Propaganda work contributes significantly to the formation of the Party's platform and political line; disseminates and educates the Party's ideology, line, policies and laws of the State; encourages and motivates the masses to actively participate in movements and practical revolutionary actions, build and defend the Fatherland, making important contributions to the great victories of the Vietnamese revolution over the past 94 years.
