Hanukkah is a celebration of the Jews' victory over the Greeks and their freedom to practice their religion. After recapturing Jerusalem, the Jews rededicated their temple and lit a lamp that miraculously stayed alight for eight days. This is why the Hanukkah festival lasts for eight days and why light is important in the celebration.
