In the inner part of the Roman province of Illyricum, which represents today's territory of Bosnia and Herzegovina, it is interesting to track the romanization process through votive inscriptions. Caused by geographical inaccessibility, the conservatism of the local population and poorly populated areas, this process was extremely slow and not as intense as in the coastal areas of the province. Despite that, 153 votive inscriptions were collected for the purpose of this thesis, all containing 18 different names of Roman deities. As most inscriptions found on the territory of the Roman Empire have a reference to the supreme deity of the state, this is also comparable to the votive inscriptions found in Bosnia and Herzegovina in which Jupiter’s name is recorded 75 times, about 49% of the total amount. On the same note, this thesis confirms that the text structure of the votive inscriptions presented in this paper does not deviate from the standard of the Roman votive inscriptions with 92.81% of inscriptions being inscriptions of an altar as the standard for vowing to the Roman deities throughout the Empire.
