What steps did sargon and his descendants take to build and maintain the akkadian empire

Sargon didn't really build it, he restored the empire. also, Sargon was not the first ruler to unite the disparate cities and tribes under one rule. The King of Uruk, Lugalzagesi, had already done this. Sargon just made the dynasty larger and stronger. He campaigned beyond the Mesopotamia. This empire stabilized the region of Mesopotamia and made the development of art, literature, science, agricultural advances, and religion. and captured all the trading routes. hope this helped, have an amazing day :)
