Esther 3:1, 5-6

After these things King Ahasuerus promoted Haman, the son of Hammedatha the Agagite, and advanced him and set his seat above all the princes who were with him.

When Haman saw that Mordecai did not bow or pay him homage, Haman was filled with wrath. But he disdained to lay hands on Mordecai alone, for they had told him of the people of Mordecai. Instead, Haman sought to destroy all the Jews who were throughout the whole kingdom of Ahasuerus—the people of Mordecai.
