The early Sephardi Jews establishment in the archipelago came from Portugal and Spain in the 17th century. In the 1850s, about 20 Jewish families of Dutch and German origins lived in Batavia. Some lived in Semarang and Surabaya. Several Baghdadi Jews also settled. Before 1945, there were about 2.000 Dutch Jews in Indonesia. Some Jews even converted to Christianity or Islam during the Japanese occupation when Jews were sent to internment camps, and the Indonesian National Revolution when Eurasians were targeted. In 1957, it was reported that around 450 Jews remained, mainly Ashkenazim in Jakarta and Sephardim in Surabaya. The community decreased to 50 in 1963 and to 20 in 1997.
