In practice, the division did not always took place. Based on the competence of the central bureaucracy of the GDL, the state performed a minimal set of functions, which was typical for traditional societies. During the reign of Ladislas Vasa, some former posts were restored and some new ones were set up, which led to an increase in the number of government officials who served the state itself. The aristocratic model of political elites recruiting determined the order of the appointment to the positions. Central and local posts were distributed by the monarch among dozens gentry families, the wealthiest and most authoritative of them monopolized the access to the highest posts in the GDL.
