Duchy of Urbino

Where it sits in time

Five thousand years, 3000 BCE to 2026; the state in gold.

Rulers

Read from the state’s own English article and its rulers’ articles, where Wikidata names no ruler.

2 rulers, 2 with terms dated as terms, covering 1443 – 1631. Median reign 4.5 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”.

What led to it, and what came of it

The investigation's own picture: 1 cause the record names and 0 results, 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.
