Dynastic spans at a glance

How long did each dynasty actually last?

Iranian history is often telescoped in popular accounts as a sequence of named empires, but the duration of each is wildly uneven — the Parthian state lasted almost five centuries, while the Afsharid empire of Nader Shah fell apart within a generation of his assassination. The chart below ranks every major Iranian dynasty by years on the throne; the dominance of Parthian and Sasanian Iran is striking, and the Pahlavi dynasty's 54 years stands out as one of the shortest royal lines on the list.

Turning points

Ten dates that changed the country

Most Iranian historians, asked to nominate the moments at which the country's trajectory measurably bent, converge on a short list. They cluster, suggestively, around three eras: the founding of the imperial idea in the 6th century BCE, the Arab and Mongol shocks of the 7th and 13th centuries, and the long modern crisis that begins with Russian pressure in 1813 and runs through to the present.

  1. 539 BCE — Cyrus enters Babylon. The first multi-ethnic empire encoded in law a doctrine of religious tolerance; sets the template every later Iranian state will measure itself against.
  2. 651 CE — Death of Yazdgerd III near Merv. End of the Sasanian state; the beginning of a four-century process by which Iran becomes Muslim without becoming Arab.
  3. 1010 — Ferdowsi completes the Shahnameh. Codifies the New Persian language as a literary instrument; ensures that the Arab conquest does not erase the Iranian cultural archive.
  4. 1219–1221 — Mongol invasion. The Khorasani cities never recover their pre-Mongol population; demographic centre of gravity shifts west to the central plateau and Fars.
  5. 1501 — Shah Ismail's Shi'i decree. Reshapes the religious geography of the Middle East and creates the Shi'a Iran of every subsequent era.
  6. 1813 & 1828 — Treaties of Gulistan and Turkmenchay. Iran loses the entire Caucasus to Russia; the modern Iranian sense of foreign encirclement is born here, not in 1953.
  7. 1906 — Constitutional Revolution. The first written constitution adopted in Asia, anchored on a parliamentary Majles — a continuing reference point for Iranian political imagination.
  8. 1908 — Oil discovered at Masjed Soleyman. The first commercial strike in the Middle East; for the next century Iran's economy and politics are inseparable from the world oil market.
  9. 1953 — Anglo-American coup against Mosaddegh. Destroys Iran's brief liberal-nationalist experiment and underwrites the radicalisation that produces 1979.
  10. 1979 — Islamic Revolution. Ends 2,500 years of monarchy in Iran and produces the first modern theocracy in any major state.
