Where it sits in time

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

How it ended, as its article says

Dissolved. Read from the article's section “lead” by its grammar; the claim is only that the article says so.

As a duchy, it broke up after the conquest of the independent Aquitanian duchy of Waiofar, going on to become a sub-kingdom within the Carolingian Empire.

10 rulers, 10 with terms dated as terms, covering 845 – 1453. Median reign 15 years. 1 of 9 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 happened within it, by century

What led to it, and what came of it

The investigation's own picture: 3 causes 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.
