Where it sits in time

Five thousand years, 3000 BCE to 2026; the state in gold, what it replaced or followed and what replaced or followed it in grey.

Before and after

The states the record files it as replacing or following, and those that replaced or followed it - Wikidata's own statements, each read from this state's side.

Rulers

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

6 rulers, 6 with terms dated as terms, covering 1299 – 1439. Median reign 12.5 years. 0 of 5 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”.

Ground held, by year

km² inside its borders as the borders dataset draws them, measured on an equal-area grid; a step series, held between the years the dataset maps.

600 km² in 1314, 2,100 km² in 1424; at its largest 2,100 km² in 1424. Cliopatria, CC BY 4.0.

Among all states

Each measure against the states that carry it, never against all of them: a bar is the share of those states below this one.

What led to it, and what came of it

The investigation's own picture: 0 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.

Open the investigation: every row with its evidence, the conditions at the time, the theories condition by condition, and the succession analysed.

Theories that apply to its ending

Of 3 theories of why states fall, 1 has every condition present at this ending; each is applied by its own logic, condition by condition, and whether its authors named this case is a footnote.

• Dynastic cycle and the decay of group feeling

  Applies by its own logic: the condition it names held here, and this is the kind of outcome it predicts — adverse regime change or the state's ending.
