 Because of events during the 20th century—including the Greek genocide, the 1923 population exchange between Greece and Turkey, a 1942 wealth tax, and the 1955 Istanbul riots—the Greek population, originally centered in Fener and Samatya, has decreased substantially.At the start of the 21st century, Istanbul's Greek population numbered 3,000 (down from 260,000 out of 850,000 according to the Ottoman Census of 1910, and a peak of 350,000 in 1919).There is a Greek newspaper, "Apoyevmatini".
