The Agiad Dynasty was an ancient Mesopotamian dynasty that ruled over the region of Akkad around 2334 to 2154 BCE. Founded by Sargon of Akkad, it is known for unifying various city-states in Sumer and establishing one of the world's first empires. The dynasty is notable for its advancements in administration, trade, and military organization. The Agiad Dynasty is also recognized for its contributions to art and literature, including the famous Epic of Gilgamesh. The dynasty eventually declined due to internal strife and external pressures, leading to its fall and the rise of the Ur III Dynasty.
