Map: Rattanakosin Kingdom in 1885, its borders in gold among its neighbours
Rattanakosin Kingdom in 1885, when it held the most ground the borders dataset draws for it: 674,800 km². Its neighbours wear their tints, as on the atlas's own map. Borders from Cliopatria (CC BY 4.0), coast and rivers from Natural Earth, cities from Reba, Reitsma & Seto 2016 (CC BY 4.0), each city under the name it bore that year.

8 rulers, 8 with terms dated as terms, covering 1782 – 1932. Median reign 18.5 years. 1 of 7 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

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 stood150 years

  • The most ground it held674,800 km²

    held more ground at its peak than 79% 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.

  • How long a reign lasted, at the median20 years

    had longer reigns, at the median, than 62% of 967 states whose dated line can carry a median.

  • Rulers on record8

    has more rulers on record than 76% of 1,968 states with a line of rulers.

What led to it, and what came of it

The investigation's own picture: 2 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.

Theories that apply to its ending

Of 3 theories of why states fall, 1 has 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.

  • 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.
