Haman being an advisor to King Xeres I, king of Persia from 518–465 BC.
He's central to the Jewish holiday of Purim: according to the Hebrew Bible's Book of Esther, Haman intended to kill all the Jews in the Persian empire.
Purim celebrates the saving of the Jewish people from Haman and, across the world, is symbolized by hamantash, or "Haman's ears" - a triangular pastry often filled with poppy seeds.
In 2018 Purim will be celebrated on the evening of February 28, through to the following evening. Expect food, drink and lots of dressing up.
Purim celebrations in Israel
Of course, there's plenty of Purim celebrations across Israel. There's an official event in Jerusalem's Safra Square; in Tel Aviv there's an annual street party, with musical performances, and there's even a Purim zombie walk in the city too.
The zombie walk will take place on March 3, so get your zombie costumes ready.
Purim around the world
In synagogues across the globe, rabbis will read the Book of Esther aloud. The reading is accompanied by blessings, before and after.
It's also common to give to charity during Purim and, on the day itself, to make a feast. That's where the hamantash comes in. It's also customary to drink lots (we mean lots) of wine.
