Early life

Cyrus was born to Cambyses I, King of Anshan, and Mandane, daughter of Astyages, King of Media, during the period of 600–599 BC.

By his own account, generally believed now to be accurate, Cyrus was preceded as king by his father Cambyses I, grandfather Cyrus I, and great-grandfather Teispes. Cyrus married Cassandane who was an Achaemenian and the daughter of Pharnaspes who bore him two sons, Cambyses II and Bardiya along with three daughters, Atossa, Artystone, and Roxane. Cyrus and Cassandane were known to love each other very much – Cassandane said that she found it more bitter to leave Cyrus than to depart her life. After her death, Cyrus insisted on public mourning throughout the kingdom. The Nabonidus Chronicle states that Babylonia mourned Cassandane for six days (identified as 21–26 March 538 BC). After his father's death, Cyrus inherited the Persian throne at Pasargadae, which was a vassal of Astyages. The Greek historian Strabo has said that Cyrus was originally named Agradates by his step-parents. It is possible that, when reuniting with his original family, following the naming customs, Cyrus's father, Cambyses I, named him Cyrus after his grandfather, who was Cyrus I. There is also an account by Strabo that claimed Agradates adopted the name Cyrus after the Cyrus river near Pasargadae.
