5 rulers, 5 with terms dated as terms, covering 1805 – 1837. Only 32 years of the line are dated - too short for a median. 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”.

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.

1800 – 18992 rows · 2 wars and battles

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.

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.

    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 3
    • a war the state is fighting, still under way, or a war the state fought, ended within 10 y — warEnded
