"Two clusters of settlements developed, one in the north, spreading out from Khurasan, and one on the westcoast, mainly Malabar, which was important in the maritime network. It seems certain that in both areas the Jews were relatively thin on the ground before the rise of Islam, although in Malabar a considerable community did exist. The earliest and most significant settlement of Jews in India was the one on the Malabar coast and these Jews had probably come by sea after the destruction of the second temple. According to legend the presence of Jews in Khurasan and on the north-western frontier of India also dates from pre-Islamic times."
