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 |
|---|---|---|---|---|
| Gabriele Maria Visconti | 1402 – 1406 | 4 years | ending not on record |
1 rulers, 1 with terms dated as terms, covering 1402 – 1406. Only 4 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”.
