Taifa of Arcos

Where it sits in time

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

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.

4,900 km² in 1021, 5,000 km² in 1071; at its largest 5,000 km² in 1031. 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.

• How long it stood134 years

  stood longer than 53% of 3,187 states with a recorded end or still standing.

• The most ground it held5,000 km²

  held more ground at its peak than 10% of 1,465 states with a border in Cliopatria.

• Wars recorded per centurynone

  had more wars on record per century than 44% of 3,187 states, counting the wars the atlas hosts under each.

What led to it, and what came of it

The investigation's own picture: 16 causes 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.

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.
