Mattathias ben Johanan was a Kohen who helped spark the Maccabean Revolt against the Hellenistic Seleucid Empire. Mattathias's story is related in the deuterocanonical book of 1 Maccabees and in the writings of Josephus. Mattathias is accorded a central role in the story of Hanukkah and, as a result, is named in the Al HaNissim prayer Jews add to the Birkat Hamazon and the Amidah during the festival's eight days.

Hanukkah is a Jewish festival commemorating the recovery of Jerusalem and subsequent rededication of the Second Temple at the beginning of the Maccabean Revolt against the Seleucid Empire in the 2nd century BCE.
