32 rulers, 32 with terms dated as terms, covering 1353 – 1707. Median reign 4 years. 12 of 32 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: 0 causes the record names and 4 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.
