Where it sits in time
Five thousand years, 3000 BCE to 2026; the state in gold.
How it ended, as its article says
Conquered by Aragon, 1442. Read from the article's section “lead” by its grammar; the claim is only that the article says so.
The two resulting kingdoms were separated until 1442, when King Alfonso V of Aragon conquered the Kingdom of Naples and unified both Kingdoms.

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 |
|---|---|---|---|---|
| Peter III of Aragon | 1282 – 1285 | 3 years | ending not on record | |
| Alfonso V of Aragon | 1416 – 1458 | 42 years | ending not on record |
2 rulers, 2 with terms dated as terms, covering 1282 – 1458. Median reign 22.5 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”.

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.
