36 rulers, 30 with terms dated as terms, covering 270 – 806. Median reign 10.5 years. 2 of 29 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”.

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.
