4 rulers, 4 with terms dated as terms, covering 1919 – 1922. Only 3 years of the line are dated - too short for a median. 0 of 3 handovers irregular - a killing, a deposition, a rival claimant, a rising or a coup beside it. The violent-handover count is withheld: power changed hands so often that any rising falls beside one (exposure 1.00, limit 0.6). A blank in the last column means no kin on record, which is coverage, never “unrelated”.
Flags and arms, in order
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.
3 rows, over a span too long to list by century.
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.

- Rulers on record4
has more rulers on record than 58% 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, 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.
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 3
- a war the state is fighting, still under way, or a war the state fought, ended within 10 y — warEnded
