A dragoman was an interpreter, translator, and official guide between Turkish-, Arabic-, and Persian-speaking countries and polities of the Middle East and European embassies, consulates, vice-consulates and trading posts. A dragoman had to have a knowledge of Arabic, Persian, Turkish, and European languages. In the Ottoman Empire, Dragomans were mainly members of the Ottoman Greek community, who possessed considerable multilingual skills, because Greek trading communities did substantial business in the markets of the Mediterranean Sea, the Black Sea, the Atlantic Ocean and the Indian Ocean. To a lesser extent, other communities with international commercial links, notably the Armenians, were recruited. Source: Wikipedia (en)
