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 |
|---|---|---|---|---|
| Hywel Dda | 904 – 920 | 16 years | ending not on record |
1 rulers, 1 with terms dated as terms, covering 904 – 920. Only 16 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.

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.
