Cyrus the Great
the founder of the Achaemenid Empire.
Under his rule, the empire embraced all the previous civilized states of the ancient Near East, expanded vastly and eventually conquered most of Southwest Asia and much of Central Asia and the Caucasus. From the Mediterranean Sea and Hellespont in the west to the Indus River in the east, Cyrus the Great created the largest empire the world had yet seen. Under his successors, the empire eventually stretched from parts of the Balkans and Thrace-Macedonia in the west, to the Indus Valley in the east. His regal titles in full were The Great King, King of Persia, King of Anshan, King of Media, King of Babylon, King of Sumer and Akkad, and King of the Four Corners of the World. He also proclaimed what has been identified by scholars and archaeologists to be the oldest known declaration of human rights, which was transcribed onto the Cyrus Cylinder sometime between 539 and 530 This view has been criticized by some as a misunderstanding of what they claim to be the Cylinder's generic nature as a traditional statement of the sort that new monarchs may make at the beginning of their reign
