the ethnic Greek population increased after Thessaloniki was incorporated into the Kingdom of Greece in 1913. By the 1680s, about 300 families of Sephardic Jews, followers of Sabbatai Zevi, had converted to Islam, becoming a sect known as the Dönmeh (convert), and migrated to Salonika, whose population was majority Jewish. They established an active community that thrived for about 250 years. Many of their descendants later became prominent in trade. Many Jewish inhabitants of Thessaloniki spoke Judeo-Spanish, the Romance language of the Sephardic Jews. From the second half of the 19th century with the Ottoman reforms, the Jewish community had a new revival. Many French and especially Italian Jews (from Livorno and other cities), influential in introducing new methods of education and developing new schools and intellectual environment for the Jewish population, were established in Thessaloniki. Such modernists introduced also new techniques and ideas from the industrialised Western Europe and from the 1880s the city began to industrialize. The Italian Jews Allatini brothers led Jewish entrepreneurship, establishing milling and other food industries, brickmaking and processing plants for tobacco. Several traders supported the introduction of a large textile-production industry, superseding the weaving of cloth in a system of artisanal production. Notable names of the era include among others the Italo-Jewish Modiano family and the Allatini. Benrubis founded also in 1880 one of the first retail companies in the Balkans. After the Balkan Wars, Thessaloniki was incorporated into the Kingdom of Greece in 1913. At first the community feared that the annexation would lead to difficulties and during the first years its political stance was, in general, anti-Venizelist and pro-royalist/conservative. The Great Thessaloniki Fire of 1917 during World War I burned much of the centre of the city and left 50,000 Jews homeless of the total of 72,000 residents who were burned out. Having lost homes and their businesses, many Jews emigrated: to the United States, Palestine, and Paris. They could not wait for the government to create a new urban plan for rebuilding, which was eventually done. After the Greco-Turkish War in 1922 and the bilateral population exchange between Greece and Turkey, many refugees came to Greece. Nearly 100,000 ethnic Greeks resettled in Thessaloniki, reducing the proportion of Jews in the total community. After this, Jews made up about 20% of the city's population. During the interwar period, Greece granted Jewish citizens the same civil rights as other Greek citizens. In
