The history of the Jews in Bulgaria goes back almost 2,000 years. Jews have had a continuous presence in historic Bulgarian lands since before the 2nd century CE, and have often played an important part in the history of Bulgaria.
Today, the majority of Bulgarian Jews live in Israel, while modern-day Bulgaria continues to host a modest Jewish population.
The Romaniote Jews or the Romaniotes (Greek: Ῥωμανιῶτες, Rhōmaniôtes; Hebrew: רומניוטים, romanized: Romanyotim) are a Greek-speaking ethnic Jewish community. They are one of the oldest Jewish communities in existence and the oldest Jewish community in Europe. The Romaniotes have been, and even remain historically distinct from the Sephardim that have settled in Ottoman Greece after the expulsion of Jews from Spain and Portugal after 1492.
Their distinct language was Yevanic, a Greek dialect that contained Hebrew along with some Aramaic and Turkish words, but today's Romaniotes speak Modern Greek or the languages of their new home countries. Their name is derived from the endonym Rhōmanía (Ῥωμανία), which refers to the Eastern Roman Empire ("Empire of the Romans", Βασιλεία Ρωμαίων). Large Romaniote communities were located in Thessaloniki, Ioannina, Arta, Preveza, Volos, Chalcis, Thebes, Corinth, Patras, and on the islands of Corfu, Crete, Zakynthos, Lesbos, Chios, Samos, Rhodes, and Cyprus, among others. Additionally, the historically large community of Jews in Bulgaria was Romaniote until the arrival of Sephardim and Ashkenazim fleeing persecution in other parts of Europe.
