Article focuses on the short rule of Sigismund of Luxembourg, king of the Romans and of Hungary, in the eastern Veneto (esp. in Belluno, Feltre and Serravalle) between 1411 and 1420. Based mostly on inedited sources from the Belluno archive, it attempts to reconstruct the historical developments of this area with a special emphasis being put on the ‘political personnel’ of King Sigismund (vicars and captains). The author shows that most of these officials as well as their garrisons came from the Czech lands. Finally, the structures of Sigismund’s administration and the often difficult coexistence with the local town communities are analysed
