"For want of a national soil, Jews in the Diaspora could not build national structures. So they built out of the substance of time. They took a specific day of the year, and kneaded and molded it until they fashioned it into an edifice. Thus each Jewish holiday is a whole construction."
– Bialik. q Karu. HaBoker, May 21, 1950
Hanukkah is called the Festival of Lights. It celebrates a miracle: In 165 BCE, the Maccabees led a band of Jews in battle against invading pagans who had desecrated the Temple.
