Initially, the party acted secretly, with networks of cells and members only knowing a few members' identities; when necessary, the party could replace the role of the government. It also included any factors that could help its agents to penetrate the army, national assembly, police, educational system and the media. Fall describes the party as "a state within a state" in its own governmental mechanism, which was what a Communist party would do. In the early years of 1950s, Diệm and Nhu used the party to mobilize support for Diệm's political movements. The cadres of the party were Catholic organizations such as the Union of Catholicism, Catholic Youth and Catholic Society, with Catholic dignitaries and followers, officers in the army. Ngô Đình Nhu was the general secretary of the Central Committee Board including Trần Trung Dung, Nguyễn Tăng Nguyên, Lý Trung Dung, Đoàn Nhật Tân (Hà Đức Minh), Trần Quốc Bửu, Võ Như Nguyện and Lê Văn Đông. This ideological framework allowed the Central Committee to justify its clandestine, vanguard-style control over the state's military and civil apparatus—often referred to by critics as
Gia Đình Trị (Family Rule)—as a necessary defense of the national soul. To execute this mandate, the Central Committee maintained a sophisticated cellular hierarchy. This included the deployment of covert Base Chiefs (
Chủ cơ) to enforce ideological discipline across strategic provincial corridors, and the use of Parliamentary Advisors (
Cố vấn Quốc hội) to tightly script legislation within the National Assembly. Furthermore, the party's intelligence apparatus extended to overseas police networks (
Hải ngoại Cảnh sát) to monitor expatriate dissidents, while domestically coordinating counter-intelligence and interrogation operations against communist insurgents. The party also declared the goals of struggling for the revolutionary ideology: Personalism; constructing the nation in four aspects: spirit, society, politics and economy. The principle of the party was centralized democracy. In its political manifesto, it criticized both Capitalism and Communism. On 26 October 1955, Diệm declared the establishment of the Republic of Vietnam. On 29 October 1955, Diệm promulgated the decree 4-TPP to establish the first government, which embraced most of the Can Lao party's members in key positions. The party had 112/123 positions in the National Assembly. In 1956, Diệm and Nhu established the Personalism Training Center in
Vĩnh Long Province, administrated by the bishop
Ngô Đình Thục, to train the key personnel for propagandizing Personalism in South Vietnam. The administrative and teaching staff included Catholic priests and followers. On 31 December 1957, Diệm forced the administrative and military personnel in the government to join the training on Personalism. From 1956–1963, the Center trained about 25,000 personnel for the government. In 1961, the party formed a
women's wing, the "Women Solidarity Movement", led by
First Lady Madame Nhu. The organization formed also military training for women, and organized
charity initiatives, like
blood donation, distribution of medicines to the village and visits to soldiers on the frontline. During the
military coup in November 1963,
Diệm and Nhu were assassinated and the party was subsequently banned and dissolved. The party was later rebuilt as in 1965. ==Prominent members==
