The topic of this research was suicide in Dubrovnik and its surroundings from the mid-seventeenth to the early twentieth century. The time span of two and half centuries allowed the investigation of the dynamics and changing features of the object under study. The main archive source for the research regarding the period 1667-1808 are the Criminal Court records (Lamenta Criminalia series). During the existence of the Republic of Dubrovnik criminal proceedings were quite different than in many other European areas in the premodern times, where the practice to bring the dead body to respond in court for the committed suicide was common. In Dubrovnik the sole aim of the trial was to exclude homicide and injuries as a cause of dead, and when this objective was reached, the procedure was brought to an end. For the research of the nineteenth and early twentieth century the principal source were Death registers for the Catholic parishes Grad, Pile, Gruž and Mihajlo-Lapad, Death registers of the Dubrovnik hospital, as well as some minor sources (the coroner's reports, etc.). For the turn of the nineteenth century and the period until the end of the World War I important information was provided by the local newspapers (Crvena Hrvatska, Dubrovnik, Prava Crvena Hrvatska). One of the main effects of suicide was a stigmatization of the family and the social environment of the suicide, and that caused the practice of concealing the self-violence as cause of death. Therefore the quantitative data know many lacunae (dark number), and that is a major methodological hinderance, playing a part in the research on suicide elsewhere, too. On the ground of the known cases of suicide only general trends can be discerned, and a more precise picture on increase and decline can be delineated only for shorter periods of time. The research includes cases of attempted suicide and the practice of leaving death notes. Local newspapers from the late nineteenth and early twentieth century reflect rising public interest for suicide, as shown by articles on ‟famous” suicides committed abroad, provided with spicy details. A long-term data on suicide disclosed aetiology that is generally present in human communities (psychical disorders as a main cause), or specific aspects present in many societies (e. g. arms as a dominant method of suicide in male population). Therefore, the conclusions are partly expected, as they follow the same pattern discovered in other European countries in the same period. However, there is also a number of features specific for Dubrovnik, e.g. the equal proportion of male and female suicide in the period of Dubrovnik Republic; seasonality, especially by female suicides in the same time span; suicides of women in the public space in the late nineteenth and early twentieth century). The longitudinal research spanning two and half centuries revealed the existence of a couple of milestones, that are interpreted from the point of view of social changes (economic parameters, demographic factors, acute crisis, immigration, presence of military troops, etc.), expanding our knowledge on the history of Dubrovnik.
