Carchemish (now Karkamis) was an important ancient city of the northern Hittite empire, located on the border between Turkey and Syria. It was also the location of one of the decisive battles in world history. It was here that the armies of Babylon and Egypt met in battle (Jer. 46:2; 2 Chr. 35:20-24). The prophet Isaiah lists Carchemish as one of the kingdoms overthrown by Sargon II of Assyria in 717 BC (Isa. 10:9). Carchemish is also mentioned in Egyptian and Assyrian texts.
