Prior to World War I, there were some 2,000–3,000 Armenians in Palestine, mostly in Jerusalem, which was captured by the British in 1917. From 1915 and onward, thousands of Armenian genocide survivors from Cilicia (Adana Vilayet) found refuge, and settled in the quarter, increasing its population. In 1925, around 15,000 Armenians are believed to have lived in all of Palestine, with the majority in Jerusalem. During the British Mandate period, the number of Armenians is estimated to have reached up to 20,000. However, the 1931 British census showed only 3,524 Armenians in all of Palestine.
