The Hebrew word Akkad (אַכַּד, also spelled Accad) refers to an ancient city in the land of Shinar (Babylonia), one of the cities founded by the mighty hunter Nimrod. It became the capital of the Akkadian Empire — one of history's earliest empires — and gave its name to the Akkadian language, the lingua franca of the ancient Near East for over a millennium.
Akkad appears in Genesis 10:10 in the table of nations as part of the kingdom of Nimrod, the first great post-Flood empire builder. The Akkadian Empire (c. 2334–2154 BC) under Sargon of Akkad was the world's first true empire. Theologically, Nimrod's kingdom at Babel/Akkad represents humanity's first organized rebellion against God's scattering command after the Flood — the concentration of power apart from God's design. The tower of Babel narrative (Genesis 11) immediately follows, placing Akkad at the center of humanity's ancient revolt against God.
