Answer 2

The first significant Jewish Diaspora was the result of the Babylonian Exile (q.v.) of 586 bc. After the Babylonians conquered the Kingdom of Judah, part of the Jewish population was deported into slavery. Although Cyrus the Great, the Persian conqueror of Babylonia, permitted the Jews to return to their homeland in 538 bc, part of the Jewish community voluntarily remained behind.
