 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.
