The Bene Israeli Jewish community of Bombay, who migrated from the Konkan villages, south of Bombay, are believed to be the descendants of the Jews of Israel who were shipwrecked off the Konkan coast, probably in the year 175 BCE, during the reign of the Greek ruler, Antiochus IV Epiphanes.[49] Mumbai is also home to the largest population of Parsi Zoroastrians in the world,[citation needed] numbering about 60,000, however their population is declining rapidly.[50] Parsis migrated to India from Greater Iran following the Muslim conquest of Persia in the seventh century.[51] The oldest Muslim communities in Mumbai include the Dawoodi Bohras, Ismaili Khojas, and Konkani Muslims.[52]
