Tacitus and Pliny the Younger prosecute Marius Priscus, proconsul of Africa, for extortion; Priscus is exiled

In 100 CE Tacitus and Pliny the Younger were assigned to act for African provincials against Marius Priscus, who had taken bribes and used his office to abuse. Pliny writes that Priscus was found guilty and exiled, and that Tacitus spoke with the majesty of his usual oratory. 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.

In 100 CE Tacitus and Pliny the Younger were assigned to act for African provincials against Marius Priscus, who had taken bribes and used his office to abuse. Pliny writes that Priscus was found guilty and exiled, and that Tacitus spoke with the majesty of his usual oratory. He did not govern Africa.

Context

Repetundae trials were the Senate’s way of hearing provincial extortion. Justice-judicial-independence-erosion is a BAD driver: improving means weakening that erosion by actually convicting a governor. Shared advocacy with Pliny is documented. This is not the Asia proconsulship Tacitus later held.

Confidence is stated on the impact path, not hidden in adjectives. Africa’s provincials, not Tacitus, were the injured parties. Mixed effects of Tacitus and Pliny the Younger prosecute Marius Priscus, proconsul of Africa, for extortion; Priscus is exiled are separate paths.

Why it matters

A named orator helping to exile a predatory proconsul is a justice path with real provincials attached. High confidence on occurrence; medium on how far the penalty repaired African harm. Later uses of the letters as a school of advocacy are reception.

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

What the sources establish

Perseus Pliny letters on the Priscus trial are the contemporary public English. Britannica independently records the 100 prosecution and exile. Dickinson’s life notice aligns. Latin Library Agricola is not this case.

Established: joint prosecution, conviction, exile, Tacitus as speaker. Not established: a unique restitution total or a recovered African petition papyrus. Conventional 100. Not his later Asia post.

Shared responsibility is part of Tacitus and Pliny the Younger prosecute Marius Priscus, proconsul of Africa, for extortion; Priscus is exiled. Naming Tacitus does not delete co-authors, institutions, or later transmitters. The lag from 0100-01-01 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.
