Licinius is executed after the war, against the received amnesty story
After Chrysopolis, Licinius was spared in a received amnesty then executed, conventionally in 325 at Thessalonica. In the causal graph this event weakens Judicial independence erosion (court capture), a driver that strengthens Rule of Law Gap from the Highest Governance Score — an improving welfare path.
Read the full account
After Chrysopolis, Licinius was spared in a received amnesty then executed, conventionally in 325 at Thessalonica.
Context
Palace killings are normal in the tetrarchic story. They remain extra-judicial. Medium confidence on motive (plot versus dynastic hygiene).
Constantine the Great’s documented role is bounded by other offices and collaborators named in the sources below.
Received 325 killing of Licinius (and later his son) after captivity. Sources disagree on pretext. Not a public independent court.
Why it matters
An execution is not Nicaea’s creed. Keep 325 council separate even if the year overlaps.
