The occupation in the mainland lasted until Germany and its ally Bulgaria were forced to withdraw under Allied pressure in early October 1944. However, German garrisons remained in control of Crete and some other Aegean islands until after the end of World War II in Europe, surrendering these islands in May and June 1945.

The Romaniote Jews or Romaniotes are an ethnic Jewish community native to the Eastern Mediterranean. They are one of the oldest Jewish communities in existence and the oldest Jewish community in Europe. Their distinct language was Judaeo-Greek or 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. They derived their name from the internal name, Rhomania (Ῥωμανία), of the Byzantine Empire. Large communities were located in Thessaloniki, Ioannina, Arta, Preveza, Volos, Chalcis, Thebes, Corinth, Patras, and on the islands of Corfu, Zakynthos, Lesbos, Chios, Samos, Rhodes, and Cyprus, among others. The Romaniotes are historically distinct and still remain distinct from the Sephardim, some of whom settled in Ottoman Greece after the 1492 expulsion of the Jews from Spain.
