Judah and his Jewish fighters defeated the Greeks one more time, then came to Jerusalem, where they cleansed the Temple of the statues of the Greek gods and dedicated it once more to the worship of the Lord. That's where the Feast of Chanukkah- or Dedication- comes from.

The Hasidim, the Pious Jews, started the rebellion against the Seleucids when Mattathias, the old priest, killed people in Modein who tried to offer sacrifices to the Greek gods. Mattathias died soon after, but his son Judah raised up a rebel army that hammered the Greeks time and time again.
