History of Hanukkah
In 175 B.C. the Seleucid king Antiochus IV Epiphanes came into power and tried to force Judeans to assimilate. The Seleucids captured the holy Temple of Jerusalem and defiled it by erecting an altar to the Greek god Zeus inside. Writing in the first century A.D., Jewish historian Josephus recorded the brutal plundering of Jerusalem and treatment of Jewish dissidents who were “whipped with rods, and their bodies torn to pieces, and were crucified, while they were still alive, and breathed. . . . And if there were any sacred book, or the law found, it was destroyed: and those with whom they were found miserably perished also.”
A priest named Mattathias and his sons rose up in rebellion. His son Judah the Maccabee (the “Hammer”) took his father’s place in the fight and led the Jewish people in many victories over the Seleucids. In 164, Judah won back Jerusalem and restored the Temple, cleansing and rededicating it.
Hanukkah, which means “dedication,” commemorates the miracle of light that occurred when Judah rededicated the Temple to the Hebrew god. Here's how Hannuakh is celebrated.
