In the contribution, the author discusses the activities of the Association of Maids/Slomšek Family in Belgrade in the 1930s. In the first part, the political image of Kingdom of Yugoslavia is presented upon the establishment of King’s dictatorship in 1929 along with the role of the biggest Slovene political party (Slovene People’s Party, i.e. SPP) which in the sphere of politics represented the interest of the Catholic Church. In the early 1930s, Catholic-oriented domestic servants deepened, strengthened and widened the activities of their organization, which during the dictatorship, in the period of dissolution of political parties and along with Korošec’s contacts with the organization, points to the impact of the (dissolved) SPP in terms of finances and personnel. In the late 1930s, this powerful rank organization fit into the idea of rank parliamentarism. Anton Korošec, an advocate of the idea, expressed his public support for the activity of the organization Slomšek’s Family, which is discussed in the second part of the contribution.
