5 rulers, 5 with terms dated as terms, covering 581 – 619. Only 38 years of the line are dated - too short for a median. 2 of 4 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 led to it, and what came of it

The investigation's own picture: 4 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; each is applied by its own logic, condition by condition, and whether its authors named this case is a footnote.
