Answer :
Final answer:
Cyrus the Great, who led the Persians to overthrow the Median dynasty and defeat the Neo-Babylonians, is the Persian ruler who gained the most lands.
Explanation:
The Persian ruler who gained the most land was Cyrus the Great. Leading the Persians, Cyrus overthrew the Median dynasty and by 539 BCE, defeated the Neo-Babylonians. His successor, Cambyses II, further extended Persia's control over Egypt and assembled a vast empire stretching from the edges of India to the Nile River.
Under the rule of Darius I, the empire was reorganized into twenty districts known as satrapies, each governed by a satrap. This resulted in better management and control over the vast lands, adding to the prosperity and stability of the empire.
Despite the achievements of other Persian rulers like Abbas I and Darius, the expansion and establishment of a massive empire under the rule of Cyrus the Great is unparalleled in Persian history.
