Annals 1–6 narrate Tiberius’s maiestas prosecutions and Sejanus’s rise and fall as an informing machine

In the Tiberian Annals Tacitus writes a system of maiestas charges, rewards for accusers, the rise of Aelius Sejanus, the destruction of Agrippina’s branch, and the 31 fall. In the causal graph this event strengthens Judicial independence erosion (court capture), a driver that strengthens Rule of Law Gap from the Highest Governance Score — a worsening welfare path.

Read the full account

In the Tiberian Annals Tacitus writes a system of maiestas charges, rewards for accusers, the rise of Aelius Sejanus, the destruction of Agrippina’s branch, and the 31 fall. He did not prosecute under Tiberius. The colour is famously hostile; that is a source limit, not a reason to drop the machine he describes.

Context

Capri withdrawal and the Senate’s fear are part of the same file. Levick-style modern cautions against villa-gossip are stored as not-unique-proof, not as a delete key.

Confidence is stated on the impact path, not hidden in adjectives. Mixed effects of Annals 1–6 narrate Tiberius’s maiestas prosecutions and Sejanus’s rise and fall as an informing machine are separate paths.

Why it matters

A school history of treason-informing is a justice path. High confidence on the existence of trials; medium on motives he ascribes. Later ‘Tiberian tyranny’ posters are mixed reception.

That reading is an impact-path choice, not a property stored on the Fact itself.

    He wrote the Tiberian books. Delatores, the Senate, and the emperor acted. Complex; he was not in that Senate.

What the sources establish

Perseus Annals English of books 1–6 and Latin Library Annals 1 are public. Britannica’s Tacitus and Tiberius articles independently treat maiestas and Sejanus as his great Tiberian themes. LacusCurtius faces the English. No 31 CE gazette is recovered here.

Established: the Tiberian maiestas-Sejanus narrative as his. Not established: a unique indictment list complete from his pages, or that every innuendo is proven. Conventional Annals date. Not a 17th-century Tacitist pamphlet.

Shared responsibility is part of Annals 1–6 narrate Tiberius’s maiestas prosecutions and Sejanus’s rise and fall as an informing machine. Naming Tacitus does not delete co-authors, institutions, or later transmitters. The lag from 0116-01-01 to any measured indicator is not treated as zero. Alternative explanations — weather, other armies, later statutes, or independent cultural change — remain live where the sources do not close them.

If a number is not in the two records named above, it is not supplied here.

Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.
