This very important urban center of the Roman province Prevalitane, which in its zenith counted over 70,000 inhabitants in its necropolises, reveals the grave places that archaeologists have established that they belonged to the Jews, which is not at all odd if one takes into account the size and importance of Duklja as military, commercial and administrative center until its destruction in a devastating earthquake. In the Middle Ages, Jews within the boundaries of today's Montenegro were in those parts that were under Ottoman rule, especially in the area of the Novi Pazar sanjak in today's Pljevlja, Plav, Gusinje, Bijelo Polje and Berane, as well as in the area of the Montenegrin coast, especially in Ulcinj . Most of this Jewish life belonged to the Sephardim who came from Spain and Portugal across Bosnia or directly from Constantinople to the early 16th century. In the 17th century, Sabbatai Zevi a famous false "Messiah", lived and is presumed to be buried in Ulcinj, after being banished from Constantinople by the grand vizier there to Dulcigno (modern-day Ulcinj). Famous Czech medieval Lenka Blehova Čelebič recently published a pioneering work entitled "Traces of the Jews in Bay of Kotor", in which she emphasized the influence of the Jews for the development of trade in these areas, stating that in many trading deals, they were at the same level as the merchants from Dubrovnik. Especially in the organization of international trade. After the wars with Napoleon and the occupation of the Boka and part of today's Montenegrin coast that was under Austrian territory, and later Austro-Hungarian, later on again, representatives of the Jewish nation appeared again. They were mostly concentrated in Kotor, as an administrative center. In Herceg Novi, a well-known Portuguese doctor and poet of Jewish origin Isaija Koen, better known for his poetic name Flavio Eborenze Didako Piro, was buried in the immersed Jewish cemetery, who wrote a book about his exile in this city. The importance, influence and respect that the Jews in Boka deserved in the image are illustrative of the fact that, according to the order of the Kotor bishop, a part of the cemetery was separated for the burial of the Jews. A part of the cemetery near the main entrance to the cemetery and in the immediate vicinity of the main chapel was set aside for the plot.
