History of the Jews in Sri Lanka (formerly Ceylon). Jews have had a presence on the island nation since at least the 9th century or even earlier. Sri Lanka was already known to Jews living in Kerala as early as the 3rd century BC. Yemeni Jewish traders used to visit Sri Lanka for trade. In the 10th century, Abu Zeid al Hasan, an Arab Muslim traveller from Siraf, Persia, stated that there were ‘a great number of Jews’ in Serendib, as Sri Lanka was known to the Arabs.
