Cyrus I or Cyrus I of Anshan or Cyrus I of Persia, was King of Anshan in Persia from to 580 BC or, according to others, from to 600 BC. Cyrus I of Anshan is the grandfather of Cyrus the Great, also known as Cyrus II. His name in Modern Persian is کوروش, Kurosh, while in Greek he was called Κῦρος, Kȳros. Cyrus was an early member of the Achaemenid dynasty. He was apparently a grandson of its founder Achaemenes and son of Teispes, king of Anshan. Teispes' sons reportedly divided the kingdom between them after his death. Cyrus reigned as king of Anshan while his brother Ariaramnes was king of Parsa. The chronological placement of this event is uncertain. This is due to his suggested, but still debated identification, with the monarch known as "Kuras of Parsumas". Kuras is first mentioned. In that year Shamash-shum-ukin, king of Babylon, revolted against his older brother and overlord Ashurbanipal, king of Assyria. Cyrus is mentioned being in a military alliance with the former. The war between the two brothers ended in 648 BC with the defeat and reported suicide of Shamash-shum-ukin. Cyrus is mentioned again in 639 BC. At that year Ashurbanipal managed to defeat Elam and became overlord to several of its former allies. Kuras was apparently among them. His elder son "Arukku" was reportedly sent to Assyria to pay tribute to its King. Kuras then seems to vanish from the historical record. His suggested identification with Cyrus would help connect the Achaemenid dynasty to the major events of the 7th century BC. Ashurbanipal died in 627 BC. Cyrus presumably continued paying tribute to his sons and successors Ashur-etil-ilani and Sin-shar-ishkun. They were both opposed by an alliance led by Cyaxares of Media and Nabopolassar of Babylon. In 612 BC the two managed to capture the Assyrian capital Nineveh. This was effectively the end of the Neo-Assyrian Empire though remnants of the Assyrian Army under Ashur-uballit II continued to resist from Harran. Media and Babylon soon shared the lands previously controlled by the Assyrians. Anshan apparently fell under the control of the former. Cyrus is considered to have ended his days under the overlordship of either Cyaxares or his son Astyages. Cyrus was succeeded by his son Cambyses I. His grandson would come to be known as Cyrus the Great, founder of the Persian Empire. It has been noted that this account of his life and reign would place his early activities more than a century before those of his grandson. This would place his fathering of Cambyses very late in life and his death at an advanced age. It has been argued that Kuras and Cyrus were separate figures of uncertain relation to each other. The latter would have then reigned in the early 6th century BC and his reign would seem rather uneventful. Due to the current lack of sufficient records for this historical period it remains uncertain which theory is closer to the facts. . It has been suggested by Louis Vandenberg that the Gur-e-Dokhtar is the tomb of Cyrus I. This is because all Achaemenid kings after Darius the Great were buried in rock-cut tombs, and because a similar building has been attributed to Cyrus the Great, it seemed logical to assume that a tomb like this must have been erected prior to the reign of Cyrus. However, other experts have claimed that it is the burial place of Mandane, mother of Cyrus the Great, while other scholars claim that the Gur-e-Dokhtar was the mausoleum of Atossa, the daughter of Cyrus the Great and the wife and queen of Darius the Great. Later, when the iron clamps were studied, it became clear that this building was erected in the 5th century BC, so it may have been for prince Cyrus the Younger.
