The article examines the beginnings of people’s assemblies in the territory of present-day Slovakia. It consists of two parts. While the first one is concerned with the period of the Mojmírid dynasty (the 9th century), the second one deals with the period of the Arpadian dynasty until the 12th century. For both periods, it is typical that assemblies were termed variously, for example as “all the Moravians”, congregatio, consilium, etc. They were mostly juridical bodies for solving conflicts between individuals, but they also functioned as electoral or consultative bodies. In the Mojmírid period, assemblies used to gather mostly once a month (in connection to the central fairs of the Moravians), while their periodicity was lower in the Arpadian times.
