How might Hanukkah have been connected to the festival of Sukkot?

Evidence from II Maccabees suggests that Hanukkah may have originated as a belated celebration of Sukkot, one of the three Pilgrim Festivals in the Hebrew Bible.21

Because the rituals of Sukkot were traditionally performed in the Temple of Jerusalem during the month of Tishri, the Maccabees were unable to observe the festival while the Temple was under the control of Antiochus IV Epiphanes. After Judas Maccabeus reclaimed and rededicated the Temple, the eight-day duration of the new holiday—which includes the seven days of Sukkot and its eighth day, Shemini Atzeret—may have been intended to compensate for the missed observance of this significant religious period.213
