Who was Cyrus the Great? Why was he so important?

Cyrus the Great destroys the nation soon after and he incorporates it into “one of the largest empires of the ancient world, the Persian Empire....” From the sixth century B.C. until the twentieth century A.D., the name of this empire is Persia. The Persian Empire is often attacked by foreign invaders because of its wealth, but the culture of Persia remains intact.
