Kamakura shogunate

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.

How it ended, as its article says

Conquered, 1333. Read from the article's section “lead” by its grammar; the claim is only that the article says so.

The Kamakura shogunate was overthrown in the Kenmu Restoration under Emperor Go-Daigo in 1333, re-establishing Imperial rule until Ashikaga Takauji and his offspring overthrew the imperial government and founded the Ashikaga shogunate in 1336 (Nanboku-chō period).

Rulers

The line of Shikken.

16 rulers, 16 with terms dated as terms, covering 1203 – 1333. Median reign 7.5 years. 0 of 15 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.

320,500 km² in 1200, 320,500 km² in 1330; at its largest 320,500 km² in 1200. Cliopatria, CC BY 4.0.

Flag or arms

Each symbol with the years its own statement gives; the timeline flies the one of the year on screen.

What happened within it, by century

Every row the atlas hosts under this state, by the century it began in: wars and battles in red, risings, regime changes and massacres beside them, everything else in grey. A tall bar is a century the record is full for, which is partly a fact about Wikipedia.

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 stood133 years

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

• The most ground it held320,500 km²

  held more ground at its peak than 67% of 1,465 states with a border in Cliopatria.

• Wars recorded per century2.3

  had more wars on record per century than 98% of 3,187 states, counting the wars the atlas hosts under each.

• How long a reign lasted, at the median8 years

  had longer reigns, at the median, than 29% of 967 states whose dated line can carry a median.

• Rulers on record16

  has more rulers on record than 89% of 1,968 states with a line of rulers.

What led to it, and what came of it

The investigation's own picture: 1 cause 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, 2 have every condition present at this ending and 1 some of them; each is applied by its own logic, condition by condition, and whether its authors named this case is a footnote.

• Demographic-structural breakdown

  Goldstone 1991 · Turchin & Nefedov 2009

  Applies by its own logic: 2 of its 3 conditions held here (it needs 2), and this is the kind of outcome it predicts — unrest, adverse regime change or the state's ending.

  • overlapping reigns — rival claimants — within 20 y, or 3 or more changes of ruler within 20 y, or 2 or more reigns of two years or less within 20 y, or a monarch deposed or killed within 20 y — handovers 4; shortReigns 2
  • a war the state is fighting, still under way, or a war the state fought, ended within 10 y — warOngoing

• Dynastic cycle and the decay of group feeling

  Ibn Khaldun 1377 · Turchin & Nefedov 2009

  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.
