Much of the population was carried off into exile in Mesopotamia. ... Babylon in turn, however, fell in 539 BC to Cyrus, the energetic king of Persia, and under his patronage and that of his successor the Jews began to revive their national life in Judah. The temple was gradually rebuilt and the High Priest was eventually recognized by the suzerain as the leader of the nation. This small Persian province was distinctively Jewish. The local representatives of the Persian king are known to have been in some cases Jews who maintained close, if not always friendly, relations with the governor of the neighbouring province of Samaria. Thus by the end of the Persian period Jerusalem was the centre of a small and economically backward but well-established Jewish community, accustomed to considerable autonomy, particularly in religious affairs, and unified around the Temple and the High Priest.
