"A generation later (520 B.C.), however, the Babylonian overlords had been replaced by a victorious Persian kingdom and these victors decided to allow some of the Jews to return to Jerusalem and rebuild the temple, a task which they completed in about 516 B.C.
Jerusalem remained in a ruinous state for a long time, however, until Nehemiah, a representative of the rich Jewish community that had grown up in Babylon, returned to Jerusalem (445 B.C.). By 433 B.C., he and his followers had succeeded in rebuilding the city's walls, restoring traditional religious observances with the city precinct, and refocusing the Jewish religion on the Temple of Jerusalem.
The Book of Zechariah is a product of that period between the rebuilding of the Temple and the restoration of Jerusalem and is an illustration of how fervently the Jews awaited that restoration."
