Rulers
Read from the state’s own English article and its rulers’ articles, where Wikidata names no ruler.
| Ruler | Reign | Length | How it ended · source | To the ruler before |
|---|---|---|---|---|
| Cambyses II | 525 BCE – 522 BCE | 3 years | ending not on record | |
| Darius II | 423 BCE – 404 BCE | 19 years | ending not on record |
2 rulers, 2 with terms dated as terms, covering 525 BCE – 404 BCE. Median reign 11 years. 0 of 1 handovers irregular - a killing, a deposition, a rival claimant, a rising or a coup beside it. A blank in the last column means no kin on record, which is coverage, never “unrelated”.

What led to it, and what came of it
The investigation's own picture: 1 cause the record names and 1 result, the strongest six of each at their own years, joined to the state by the kind of claim - a recorded statement solid, the article's sentence dashed, a theory dash-dot.
Open the investigation: every row with its evidence, the conditions at the time, the theories condition by condition, and the succession analysed.
Theories that apply to its ending
