What it is
The Behistun (Bisitun) Inscription is a monumental relief and trilingual text carved into a limestone cliff above the royal road in western Iran (ancient Media), about a hundred metres above the ground. Commissioned by Darius I around 520 BCE, it combines a relief of the king triumphing over rebel claimants with a long inscription — in Old Persian, Elamite and Babylonian cuneiform — narrating how Darius came to and secured the throne. It is the longest and most important royal inscription of the Achaemenid period.
Historical context
Darius was not the natural heir. He came to power in 522 BCE in disputed circumstances, after the death of Cambyses II and the killing of a figure the inscription calls Gaumata, "the magus," whom Darius accuses of impersonating Cambyses's dead brother Bardiya and usurping the throne. Darius's first regnal years were consumed by a wave of revolts across the empire — Babylon, Media, Persia, Elam, Margiana and more — which the inscription records him crushing in rapid succession. Behistun is the official account of that crisis and of Darius's right to have ended it.
What it argues — or its purpose
The inscription is a sustained act of legitimation. Darius presents himself as the restorer of an order that Gaumata's usurpation and the rebellions had overthrown, ruling by the favour of the god Ahuramazda and by his own truth against the "Lie" (drauga) of the rebels. The platform reads it under kingship and legitimacy: like the Cyrus Cylinder, it is the king's own account of why his rule is rightful, addressed to the peoples he governs. It is also an artefact of imperial communication: Darius records that copies of the text were dispatched throughout the empire, and an Aramaic version has indeed turned up among the Elephantine papyri in Egypt — the same message broadcast across a continent in multiple languages.
Reception and influence
Behistun's modern importance is twofold. As a historical source it is the Achaemenid state's fullest first-person narrative of how power was seized and held. As a scholarly key it is decisive: in the 1830s and 1840s Henry Rawlinson copied the Old Persian text at great personal risk and used it, as a kind of Rosetta Stone for cuneiform, to crack the Old Persian script and then Babylonian — opening the entire written record of ancient Mesopotamia to modern reading.
Source discipline
Behistun is Darius's own version, carved to justify a contested accession; many scholars suspect the "Gaumata the impostor" story masks Darius's own usurpation of a legitimate Bardiya. It must be read as royal apologetic, against Herodotus's parallel account and the administrative record, not as neutral history. Cite by column and paragraph of Schmitt's edition.
