As unit (Gastaldia) of the Aquileia's patriarchate the Tolmin region was all through the Middle Ages treated as a special land. The Bovec and Kobarid regions on the right bank of the river Soča, however, belanged to another landlord — the monastery in Rožac (Rosazzo). The Tolmin region was under the ecclesiestical authority of the patriarch, directly under him was the Čedad (Cividale) Capitol, which was very unpopular because of its tithe forcing up. The author gives some data on the uprisal of the population of the Kobarid region in 1331, when the Capitol tried to break its resistence with the crusading army. The population, however, was supported by the monastery in Rožac.
