n the Middle and Early Modern Period Istria, today part of Croatia, was divided into the Austrian and Venetian part. In the paper the focus was mostly on the Venetian part, while the Austrian one was only sporadically mentioned. The analysis was based on Marriage Parish Registers of Rovinj and Savicenta, Books of marital litigation, Books of marital absolution and wedding licence from the Diocesan Archives in Poreč and Istrian towns’ Statutes. The paper deals with property relations in marriage, especially with three types of marriages in Istria (Istrian, Slavic and Venetian). Special attention is given to marriage gifts (dos, contradote and basadego), age of marriage and choice of the partner. In the paper are also observed usages in the case of marrying widows (mattinata, charivari), wedding witnesses and the privatization of marriage at the end of the modern period which was unlike of the Middle Ages and early modern period when the wedding ceremony was more a public than a private event.
