What led to it, and what came of it

The investigation's own picture: 5 causes the record names and 0 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.

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.
