Hanukkah celebrates the victory of the Maccabees and the miracle of light burning in the Holy Temple. When the Maccabees conquered the Greek oppressors and took back the Temple, they cleaned and repaired the damage, and went to fetch the oil needed for the ner tamid (eternal light) menorah in the Temple. It took eight days to come back with clean oil. During that time, the oil they thought would only last for one day, lasted for 8 days and nights. The Hanukkah holds nine candles: one for each of the 8 nights of Hanukkah, plus a shammus (servant) which usually sits higher and does the job of lighting the other candles.
