14 rulers, 14 with terms dated as terms, covering 1973 – 2025. Median reign 2 years. 12 of 17 handovers irregular - a killing, a deposition, a rival claimant, a rising or a coup beside it. The violent-handover count is withheld: power changed hands so often that any rising falls beside one (exposure 0.83, limit 0.6). A blank in the last column means no kin on record, which is coverage, never “unrelated”.
