appointed by his father as the governor of the northern part of Babylonia, including its city Babylon, whilst the central and southern part continued to be directly supervised by Cyrus and his bureaucrats. Before his appointment, Cambyses had taken part in a ritual at the regular New Year festival on 27 March 538 BC, where he received the royal sceptre in Esagila, a temple dedicated to the god Marduk. His governorship, however, lasted only nine months; Cyrus dismissed him from the post in December 538 BC for unknown reasons. After his dismissal, Cambyses continued to mostly reside in the Babylonian cities of Babylon and Sippar. According to Babylonian records, both Cambyses and Cyrus carried the title of "King of Babylon, King of the Lands" in 538/7 BC, which indicates that Cyrus had appointed him as co-ruler some years before his campaign against the Massagetae. Cyrus' younger son, Bardiya, was given his own realm in Central Asia, which was exempted from paying tribute. Cambyses reportedly took part in the expedition against the Massagetae, but, due to his being the heir to the throne, he was sent back to Persia, before Cyrus fell to the Massagetae. Cambyses had his father's body carried to Pasargadae in Persis, where he was buried in a tomb that had been prepared for him earlier. Military campaigns Preparations against Egypt and the conquest of Cyprus Cambyses' accession to the Achaemenid throne was relatively smooth. Ruling over a vast but young empire, Cambyses preserved his authority over the subjugated lands, but also expanded his dominion over Egypt, the last prominent power in the Near East. According to the French Iranologist Pierre Briant, "this must not be seen as a more or less irrational and uncontrollable desire to take over the entire inhabited world". On the contrary, Cambyses' action had already been planned by his father, who wanted to unify Babylonia with the lands of the Trans-Euphrates (an area that stretched from Posideium to Egypt). This would eventually require conquering the lands situated between the Euphrates and Nile rivers, and therefore necessitated conflict with Egypt, which had previously and more recently shown interest in the area. The incumbent pharaoh of Egypt was Amasis II, who had been ruling since 570. His ally, Polycrates, a Greek ruler of Samos, posed a considerable threat to the Achaemenids, launching several raids that jeopardised Achaemenid authority. However, Polycrates eventually forsook his Egyptian allies,
