# After Agricola’s consulship, Tacitus marries his daughter, binding the historian to the British commander’s house

Date: 77

## The fact

Agricola 9 states that the consul Agricola betrothed his daughter of excellent promise to [Tacitus](/people/tacitus) as a young man and married her after the consulship, then went to Britain. Conventional date is 77 CE. He did not command Britain by marrying. Archival locator: The Latin Library — Tacitus, Agricola at https://www.thelatinlibrary.com/tacitus/tac.agri.shtml (The Latin Library). Independent locator: Britannica — Tacitus at https://www.britannica.com/biography/Tacitus-Roman-historian (Encyclopaedia Britannica).

## Context

Senatorial careers ran on affinity. The match explains access to Agricola’s memory and the pietas claim of the 98 book. Cohesion here is household-political belonging, not a wedding-census. Domitian’s later treatment of Agricola is another row. Julia Agricola as a named wife is poorly documented beyond this sentence.

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

## Evidence and sources

Latin Library Agricola 9 is the public Latin of the betrothal and marriage. Britannica independently states the marriage to Agricola’s daughter. Perseus English of the Agricola carries the same. No dowry tablet is cited. Loeb is a later bilingual book. Archival locator: The Latin Library — Tacitus, Agricola at https://www.thelatinlibrary.com/tacitus/tac.agri.shtml (The Latin Library). Independent locator: Britannica — Tacitus at https://www.britannica.com/biography/Tacitus-Roman-historian (Encyclopaedia Britannica).

Official or archival record: The Latin Library — Tacitus, Agricola (https://www.thelatinlibrary.com/tacitus/tac.agri.shtml; The Latin Library).

## Significance

Without the marriage there is no Agricola as a son-in-law’s book. That is a cohesion-and-memory path of modest size. High confidence on the claim in Agricola 9; the wife’s inner life is not recovered.

Independent locator: Britannica — Tacitus at https://www.britannica.com/biography/Tacitus-Roman-historian (Encyclopaedia Britannica).

Confidence is stated on the impact path, not hidden in adjectives. The Agricola monograph is a later, separate Fact. Mixed effects of After Agricola’s consulship, Tacitus marries his daughter, binding the historian to the British commander’s house are separate paths.

## What is established and what is not

Established: marriage after Agricola’s consulship as the Agricola states. Not established: a civil-registry day, children besides the implication of a household, or a portrait. Conventional 77. Not the 98 publication. Archival locator: The Latin Library — Tacitus, Agricola at https://www.thelatinlibrary.com/tacitus/tac.agri.shtml (The Latin Library). Independent locator: Britannica — Tacitus at https://www.britannica.com/biography/Tacitus-Roman-historian (Encyclopaedia Britannica).

Shared responsibility is part of After Agricola’s consulship, Tacitus marries his daughter, binding the historian to the British commander’s house. Naming Tacitus does not delete co-authors, institutions, or later transmitters. The lag from 0077-01-01 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.

The attached driver is [social-cohesion](/drivers/social-cohesion). The welfare reading used in this dossier is improving. That reading is an impact-path choice, not a property stored on the Fact itself.
