The Party also operated intermittently, as the need arose, political courses and study groups for its activists and propagandists. In 1969, for example, more than 20,000 study centers were organized throughout the country for the study of the official, newly published _History of the Workers' Party of Albania_. The teaching program of all the Party schools and study centers included such topics as the importance of Communist education; the origins and development of Communist morality; socialist attitudes toward work and property; the importance of patriotic education; the history, theories, and tactics of the international Communist movement; and the history and statutes of the Party. Mass Organizations In its exercise of power and control over every phase of the people's lives, the Party also utilizes several mass, or social, organizations, the most important of which are the Democratic Front, the Union of Albanian Working Youth, the Union of Albanian Women, and the United Trade Unions of Albania. In a speech at the Fourth Congress of the Democratic Front held in September 1967, Enver Hoxha said that the mass organizations, as components of the system of the dictatorship of the proletariat were "levers of the Party for its ties with the masses" and that they carried out their political, executive, and organizational work in such a way as to enable the Party directives to be correctly understood and implemented by all segments of the population. Party Secretary Hysni Kapo, in a speech delivered at a Party seminar in January 1970, declared that the Party carried out its mission through its own organizations and through the activities of its "levers, the mass organizations, such as the trade unions, youth, Democratic Front, women's, and the people's councils," thus revealing that even the people's councils were mere Party levers. By relying on these powerful levers, Kapo added, the Party guaranteed its links with the masses and obtained their support for its policies. He remarked further that, although there were not Communists in every family in the country, everyone in the family belonged to some kind of organization. The Party has set the implementation of its line as a general primary goal for all mass organizations. Considered as powerful Party levers, they are required to convey the Party line to the people and to bring to the Party the people's attitudes and grievances. As Party instruments they must mobilize, organize, and orient the people during the process of the building of socialism. The mass organizations also assist the Party in its control over the administration and management of state enterprises and initiate new actions and new movements in all work centers.
