Megillat Esther and Sefer Zekharya

According to the chronology posited by Seder Olam, Ahashveyrosh was the king immediately after Cyrus but before Darius, and the story of Megillat Esther immediately led to the building of the second Beit HaMikdash and a mass Aliya. However, according to the common historical approach Ahashverosh was the king who succeeded Darius. The Beit HaMikdash was already built and two decades pass before any new Aliya movement. In fact, no major event takes place immediately after the events in Megillat Esther. However, parallels between Megillat Esther and the prophecies of Zekharya imply that the initiators of the holiday of Purim understood that the ultimate success of the Return to Zion and the rebuilding of the Beit HaMikdash depended on the implementation of social Mitzvot.
