Primary sources At some time between his coronation and his death, Darius left a tri-lingual monumental relief on Mount Behistun, which was written in Elamite, Old Persian and Babylonian. The inscription begins with a brief autobiography including his ancestry and lineage. To aid the presentation of his ancestry, Darius wrote down the sequence of events that occurred after the death of Cyrus the Great. Darius mentions several times that he is the rightful king by the grace of the supreme deity Ahura Mazda. In addition, further texts and monuments from Persepolis have been found, as well as a clay tablet containing an Old Persian cuneiform of Darius from Gherla, Romania (Harmatta) and a letter from Darius to Gadates, preserved in a Greek text of the Roman period. In the foundation tablets of Apadana Palace, Darius described in Old Persian cuneiform the extent of his Empire in broad geographical terms: Herodotus, a Greek historian and author of The Histories, provided an account of many Persian kings and the Greco-Persian Wars. He wrote extensively on Darius, spanning half of Book 3 along with Books 4, 5 and 6. It begins with the removal of the alleged usurper Gaumata and continues to the end of Darius's reign.

Richard Stoneman likewise refers to Irdabama as the mother of Darius. The Behistun Inscription of Darius states that his father was satrap of Bactria in 522 BCE. According to Herodotus (III.139), Darius, prior to seizing power and "of no consequence at the time", had served as a spearman (doryphoros) in the Egyptian campaign (528–525 BCE) of Cambyses II, then the Persian Great King; this is often interpreted to mean he was the king's personal spear-carrier, an important role. Hystaspes was an officer in Cyrus' army and a noble of his court. Before Cyrus and his army crossed the river Araxes to battle with the Armenians, he installed his son Cambyses II as king in case he should not return from battle. However, once Cyrus had crossed the Aras River, he had
