When Sargon died, Rimush, his son, inherited the empire, however, he was plagued by constant uprisings – after he died his brother took the throne. He too was plagued by constant rebellion, and was later usurped by Naram-Sin. Naram-Sin quickly destroyed and dispersed the Sumerian rebels and also went on a vast campaign of conquest, taking his armies to Lebanon, Syria and Palestine, and then to Egypt.
