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 |
|---|---|---|---|---|
| John, King of England | 1177 – 1216 | 39 years | ending not on record |
1 rulers, 1 with terms dated as terms, covering 1177 – 1216. Only 39 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”.
