8 rulers, 8 with terms dated as terms, covering 1975 – 2021. Only 46 years of the line are dated - too short for a median. 5 of 10 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 0.77, limit 0.6). A blank in the last column means no kin on record, which is coverage, never “unrelated”.
Heads of government
The line of Prime Minister of São Tomé and Príncipe, drawn and never measured: a cabinet is not a reign.
