In this MA thesis, a fascicule with Šibenik export licenses from 1642 and 1643, which is kept in the State Archives in Zadar, is analyzed. At the beginning of the paper, the problem of insufficiently researched Dalmatian history of the first half of the 17th century, especially topics related to the economy, is articulated. Paper explains the role that export licenses had in the implementation of Venetian trade policy and customs control, as well as their importance in terms of a historical source that allows the creation of a reliable study of maritime trade in Dalmatian cities. The main political and economic features of Dalmatia in the first half of the 17th century are outlined, with special emphasis on trade, both with the Ottoman hinterland and with the western Adriatic coast, especially Venice. Before analyzing Šibenik's export, an overview of the political, economic and social conditions in the city during the first half of the 17th century is given. Most of the paper is occupied by the analysis of export licenses from 1642 and 1643, divided into eight subchapters. The obtained data indicate a large number of issued licences, especially in May and October as the most important months for Šibenik's export. Traders who belonged to the Šibenik citizenry played a prominent role in export, as well as local patrons (sea captains) who were mentioned in over 75% of issued licences. By far the most important export item in Šibenik, listed in more than 50% of all licences, is rassa or rassia (coarse woolen cloth). What makes the analyzed licences stand out is the uniformity of export destinations and the role of the guarantor as an integral part of each licence. A comparison with Šibenik's export licenses from the 15th and 16th centuries showed significant differences, not only in quantity, but also in the importance of individual export items. Future research of the Šibenik maritime trade in the first half of the 17th century will require the expansion of these data with those from notarial records.
