What does the Hebrew name Hanukkah refer to in the story of Judas Maccabeus?

In the context of the story of Judas Maccabeus, the Hebrew name Hanukkah means "dedication".12

This term refers specifically to the rededication of the Temple of Jerusalem in 164 BCE. After reclaiming the Temple from the Seleucid forces of Antiochus IV Epiphanes, who had desecrated the site, Judas Maccabeus ordered its cleansing and the installation of a new altar. Upon the completion of these efforts on the 25th of Kislev, Judas proclaimed that the dedication of the restored Temple should be observed annually for eight days.324

While the holiday is often associated with the miracle of the oil in later tradition, its historical origin is rooted in this act of religious restoration and the Maccabees' successful defense of Jewish practice against forced Hellenization.32
