According to the Diodorus Siculus' Historical Library, Artaxerxes III spent a year campaigning in Egypt and fought there for seven years. Egypt finally fell to the Persians. Nekht-har-hebi retreated to Ethiopia and claimed to rule from there. The Greeks and Persians fought over to him.

In 338 BC, Philip II of Macedonia defeated the Athenians at Charoneia, Persian king was Assassinated by Bagoas. And all the princes were murdered. Persians found a remained Persian prince called Darius III.

Persian-Greek Wars

In 500 BC, the Ionia revolted. They burned Sardis and war went on until the Persians defeated the Greek fleets off the Miletus in 494 BC.

The Ionian cities that had been allowed to have local autonomous, were now brought under imperial administration. Private wars between cities were no longer allowed but were arbitrated. According to Herodotus, Darius appointed his son-in-law Mardonius, eject irresponsible despots from Ionian cities and set up democracies.

The name Iran derives from the word "Airyana". This word is used in the Avesta- the holy book of Zoroastrians- dating 3000 years ago (maybe more) and changed to "Aryan-Shatr" and "Iran-Shatr" in the first centuries A.D. and finely ended in "Iran" in Firdowsi's shahname.

In the first millennium BC, some tribes of the Iranians moved gradually into the mountains area of Zagros, neighboring the Elamites in south, Assyrian empire in west and some other prior Aryans and non-Aryans in north.

The Scholars divides them to three parts. The Medes settled in north western, west and center of Iran, the Persians in south western and the Parthians in north eastern of Iran.

The reason is that these three major groups constructed 3 -Fourth, fifth and Sixth- "great eastern monarchies" (As English historian, Henry Rawlinson named) From 8^th Century BC, to 3^th Century A.D and after that the national-religious Empire of Iran was built by Ardeshir Babakan, called the Sassanid Empire, longing for 430 years. It ended in 650 A.D. the year that Yazdgerd III- the last Zoroastrian king of Iran- was murdered. And Muslim Arabs' conquer was completed in Iran.
