In the Queen Esther short story, first, Esther was chosen as queen. After that, Haman, full of hatred for the Jews, managed to get the king to issue a decree for their destruction. Esther, upon learning this, decided to take a huge risk. She prepared herself through fasting and prayer and then went to the king unbidden. This led to a series of events where she ultimately revealed Haman's evil plot and the Jews were saved from the planned massacre.
The key events start with Esther's rise to queenship. Next, Haman's jealousy and his devising of a plan to eliminate the Jews is a major part. Esther's discovery of this plan and her decision to act are crucial. She then uses her relationship with the king to set up a situation where she can expose Haman. Her banquet invitations to the king and Haman are part of her strategy. Finally, the king's realization of Haman's true nature and the reversal of the decree against the Jews are the main events that shape the story of Queen Esther.
