The volume offers an idea of the confluence between the Western and Eastern worlds, reflected by genealogy and heraldry, the main auxiliary sciences of history, but also by others, such as prosopography, onomastics, sphragistics, philately or numismatics. The selected articles guarantee a reference volume that aims to promote a multitude of research tracks characteristic for the Romanian space, and in a broad sense the Central-European one. Encompassing facts and people from the fifteenth century onwards, this corpus of texts ensure a better connection of the regional research with the European historiography. One may also consider that the approached subjects have been increasingly sought after by historians from other areas because of the general lack of updated information on the genealogy and heraldry of the regional elites. Most texts included in this volume were presented during the 19th National Congress of Genealogy and Heraldry. Held in Iasi between 11 and 13 May 2023, the event marked the 25th anniversary of the "Sever Zotta" Institute. In parallel, the same event also marked 300 years since the death of the scholar Dimitrie Cantemir, 175 years since the Romanian Revolution of 1848, 150 years since the death of Alexandru Ioan Cuza, the first ruler of the United Principalities, and 80 years since the establishment of the Circle of Romanian Genealogists. This volume continues the series of collections of studies revolving around heraldry and genealogy, containing nineteen texts arranged chronologically in two substantial sections, by established authors - historians, art historians, archivists, etc.
