This doctoral thesis analyses and researches activities of Italian representatives in the Dalmatian parliament (Dieta Provinciale Dalmata) and furthermore presents their parliamentary activity in this highest representative and autonomous body in the Kingdom of Dalmatia. Admittedly, the autonomy of the Provincial Parliament and the Kingdom of Dalmatia itself was to great extent restricted. Parliamentary activity of Italian representatives is the integral part of their political struggle in the Provincial Parliament from 1883 to 1912 (1918) and it is connected with activities of Italian representatives from Dalmatia in the Imperial Council in Vienna from 1883 to 1897. According to Italian nationalistic attitudes the power in Dalmatia belongs solely to pro-Italian inhabitants and this idea is "based" on the allegedly incessant continuity of the superior Latin/Italian culture ever since the Roman Empire through the Venetian Republic to the first decades in the 19th century. Furthermore, from their perspective the Kingdom of Dalmatia is both geographically and nationally the part of Madre patria italiana. They emphasized natural bonds that connect Dalmatia and Italy and on the other hand differences in interests of Dalmatia and Croatia that have nothing to offer one another materially nor morally. Being extremely determined in rejecting unification of Dalmatia to Croatia they advocated strong connections of Dalmatia to Istria, Trieste, Rijeka and other Italian provinces in the Habsburg monarchy which practically revealed that their integration efforts were directed outside of the province within renewed and united Italy. During the 1880s in the process of intensive national integration three national circles can be distinguished in Dalmatia: Croatian, Serbian and Italian. Moreover, certain politicians do not change only political but national sides as well. The period at the end of the 19th century is marked by persistent Croatian-Italian struggle over Zadar as the only Italian stronghold in Dalmatia followed by tensions, riots inside of the Italian community between young radicals and moderates of the older generation. According to analysis of several model cases in family histories national identity will be represented not as something given in advance by origin or language but as a social and political construct. In the case of Dalmatian Italians it was a question of accepting one of the several identity options. Identity and collective bibliography of Italians in Dalmatia will reveal that one identity determinant is always Dalmatia as their home but generally as part of the Italian state. Nationality of parliament members as a collective "feature" does not result from ethnic description only but from political self-understanding of the politicians. In conclusion, this thesis strives to elaborate the hypothesis that the national identity of Dalmatian Italians - Italian members in the Dalmatian parliament is significantly marked by their political engagement. The main object of the analysis is political organizing of Dalmatian Italians which stresses Italo-Dalmatian and Italian nationalism of irredentist characteristics.
