Where it sits in time
Five thousand years, 3000 BCE to 2026; the state in gold.
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 |
|---|---|---|---|---|
| Ranuccio II Farnese | 1646 – 1649 | 3 years | ending not on record |
1 rulers, 1 with terms dated as terms, covering 1646 – 1649. Only 3 years of the line are dated - too short for a median. A blank in the last column means no kin on record, which is coverage, never “unrelated”.
Flags and arms, in order
Each symbol with the years its own statement gives; the timeline flies the one of the year on screen.

Applies by its own logic: the condition it names held here, and this is the kind of outcome it predicts — adverse regime change or the state's ending.
