What strategy did Cyrus the Great use as he expanded the Persian Empire? He kept local leaders in place.
He destroyed rebellious cities.
He made tribes become nomadic.
He gained loyalty by giving away gold.

He kept local leaders in place.

Explanation:

Cyrus the Great was the founder and ruler of the Achaemenian empire. He would also expand and conquer lands as far as Western and Central Asia.

But despite successfully conquering these far-off lands, Cyrus did not resort to untoward or unnecessary violence. He would make the local leaders remain in power, to rule for him. And in that act, he made himself popular and a considerate leader, loved by the people.

Thus, the correct answer is the first option.
