585 Bc: Peace treaty among Iran & Lydia
Iran under Media Empire In the second half of the 7th century BC,
the Medes gained their independence and were united by a dynasty. The
kings who established the Mede Empire are generally recognized to be Phraortes and his son Cyaxares. They were probably chieftains of a nomadic Mede tribe in the desert and on the south shore of the Caspian, the Manda, mentioned by Sargon, and they likely founded the capital at Ecbatana. The later Babylonian king Nabonidus also designated the Medes and their kings always as Manda.
According to Herodotus, the conquests of Cyaxares the Mede were
preceded by a Scythian invasion and domination lasting twenty-eight
years (under Madius the Scythian, 653-625 BC). The Mede tribes seem to
have come into immediate conflict with a settled state to the West
known as Mannae,
allied with Assyria. Assyrian inscriptions state that the early Mede
rulers, who had attempted rebellions against the Assyrians in the time
of Esarhaddon and Assur-bani-pal, were allied with chieftains of the Ashguza (Scythians) and other tribes - who had come from the northern shore of the Black Sea and invaded Armenia and Asia Minor; and Jeremiah and Zephaniah in the Old Testament agree with Herodotus that a massive invasion of Syria and Philistia by northern barbarians took place in 626 BC. The state of Mannae was finally conquered and assimilated by the Medes in the year 616 BC.
In 612, Cyaxares conquered Urartu, and with the help of Nabopolassar the Chaldean, succeeded in destroying the Assyrian capital, Nineveh;
and by 606, the remaining vestiges of Assyrian control. From then on,
the Mede king ruled over much of Iran, Assyria and northern
Mesopotamia, Armenia and Cappadocia. His power was very dangerous to his neighbors, and the exiled Jews expected the destruction of Babylonia by the Medes (Isaiah 13, 14m 21; Jerem. 1, 51.).
When Cyaxares attacked Lydia, the kings of Cilicia and Babylon intervened and negotiated a peace in 585 BC, whereby the Halys was established as the Medes' frontier with Lydia. Nebuchadrezzar
of Babylon married a daughter of Cyaxares, and an equilibrium of the
great powers was maintained until the rise of the Persians under Cyrus.
About the internal organization of the Mede Empire, we know that the
Greeks adopted many ceremonial elements of the Persian court, the
costume of the king, etc., through Media.
