What led to it, and what came of it
The investigation's own picture: 10 causes the record names and 2 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.

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.
