As King Ahasuerus was raiding Greece, he brought back every fair maiden to Persia. He let them have what ever they wanted to beautify themselves for one year. Hadassah was sone of the fair maidens. Hadassah was Jewish and was raised by her uncle, Mordecai. Hadassah changed her name to Esther, for Hadassah was Jewish, and her name had to be Persian. Mordecai also told Esther not to reveal that she was a Jew. As the end of the year came, Esther was presented to the King and the King was pleased, Henceforth King Ahasuerus married Esther.
About this time, Mordecai discovered an assassination plot against King Ahasuerus. Esther revealed the plot to Ahasuerus and the plot was stopped. At that time Mordecai was not rewarded.
Haman was a descendant of King Agag, who had fought against Saul. Haman hated the Jews, he hated them so much that he wanted to kill all of them. Because he thought Mordecai was not giving him enough respect, he petitioned the King that he might wipe out a certain wicked nation, and the King agreed. The King trusted Haman, and did not look into this matter.
Haman posted a decree that all Persians, on a certain day, would attack the Jews. Mordecai noticed this decree and put on sack clothes and ashes. Mordecai told Esther about the evil plan, and asked that Esther might go to the King. Esther agreed, and she asked that the Jews would wear sack clothes and ashes for her.
Esther was not supposed to go to the ing without permission, she was only allowed to go to the king if the king called for her. Esther had appeared in front of the king, and the king had accepted her. Esther asked that King Ahasuerus and Haman go to a banquet prepared by her. After this banquet was over, Esther asked that they might come to a banquet a second time the next week. At that next banquet, Esther revealed Haman's evil plan and all of Haman's family were hanged.
The King issued a decree that the Jews could fight back on that certain day, and guess what, and that day the Jews won! The day was proclaimed as Purim, and is a festival that Jews now celebrate. Mordecai was then promoted to Haman's former position in the King's court.
