The Akkadians were the culture that began the tradition of loyalty to an individual leader instead of a state

Explanation:

The Akkadians were the ones that started the tradition of an individual leader instead of a state. Evidence of this is how Sargon founded the Akkadian empire by conquering the city of Uruk from the Sumerian empire to govern and to pass his empire to his sons. Even though there were revolts and attempts to take them out of power. The tradition was successful and the Sargon dynasty lasted almost 200 years. Much earlier than the rest of the cultures in the options because they only adopted it after they were conquered by the Akkadians and threw them off the power to sit their kings in their thrones. Eventhough they had kings before, they were not loyal to them as akkadians did, they were loyal to the state.
