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 |
|---|---|---|---|---|
| Afonso III of Portugal | 1249 – 1279 | 30 years | ending not on record | |
| Maria II of Portugal | 1826 – 1835 | 9 years | ending not on record |
2 rulers, 2 with terms dated as terms, covering 1249 – 1835. Median reign 19.5 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”.
Flags and arms, in order
