The following is a summary of the activities of the Persian kings in secular history:

1. Cyrus was the founder of the Mede-Persian Empire. He conquered the Media, Lydia, and Babylonain Empires. Because he was a gracious liberator, he permitted the conquered nations to worship their own gods. He was benevolent toward various captive people who hadsuffered under the rule of Nebuchadnezzar and his successors. The Jews were allowed toreturn to Jerusalem to rebuild their temple and Cyrus even gave financial help. Also, hebuilt Parargardae, a royal residence 100 miles north of Shiraz.

However, on theway home from his conquest he heard that a pretender has taken the throne pretending to beanother son of Cyrus called Smerdis. Cambysses died on his return trip.
3. Pseudo Smerdis, the imposter, ruled for several months. He gained a large followingby remitting taxes for three years throughout the empire. However, Darius kept theloyalty of the Persian army and eventually captured and killed Pseudo Smerdis.

• Cyrus Charter of Human Rights

  Cyrus the Great (580-529 BC) (known as Kourosh in Persian; Kouros in Greek; Kores in Hebrew) was the first Achaemenian Emperor and founder of Iran, who issued a decree on his aims and policies, later hailed as his charter of the rights of nations. Inscribed on a clay cylinder, this is known to be the first declaration of Human Rights, and is now kept at the British Museum. A replica of this is also at the United Nations in New York. Part of his charter states: "I am Cyrus. King of the world. When I entered Babylon... I did not allow anyone to terrorize the land... I kept in view the needs of people and all its sanctuaries to promote their well-being... I put an end to their misfortune. The Great God has delivered all the lands into my hand; the lands that I have made to dwell in a peaceful habitation.... . .When my soldiers in great numbers peacefully entered Babylon... I did not allow anyone to terrorize the people... I kept in view the needs of people and all its sanctuaries to promote their well-being... Freed all the slaves... I put an end to their misfortune and slavery (referring to the Jews and other religious minorities). The Great God has delivered all the lands into my hand; the lands that I have made to dwell in a peaceful habitation... "
