Joshua lists the king of Megiddo among the Canaanite rulers defeated during Israel's conquest, although Judges indicates that the tribe of Manasseh initially failed to drive out the inhabitants of Megiddo.
Megiddo later became an important administrative city during the Israelite monarchy. First Kings associates Megiddo with Solomon's building activities.
King Ahaziah of Judah died following the revolt of Jehu after fleeing toward Megiddo. More famously, King Josiah confronted Pharaoh Neco near Megiddo and was mortally wounded, an event remembered as a national tragedy.
Revelation 16 uses the name Harmagedon or Armageddon, traditionally understood as "Mount of Megiddo," for the place associated symbolically with the final gathering of kings for battle.
