Task: Question Answering
Input (English): After the assassination of Domitian in AD96, and amid the predictable turmoil of the regime change, Tacitus used his new-found freedom to publish this, his first historical work. During the reign of Domitian, Agricola, a faithful imperial general, had been the most important general involved in the conquest of a great part of Britain. The proud tone of the Agricola recalls the style of the laudationes funebres (funeral speeches). A quick résumé of the career of Agricola prior to his mission in Britain is followed by a narration of the conquest of the island. There is a geographical and ethnological digression, taken not only from notes and memories of Agricola but also from the De Bello Gallico of Julius Caesar. The content is so varied as to go beyond the limits of a simple biography, but the narration, whatever its form, serves to exalt the subject of the biography. Tacitus exalts the character of his father-in-law, by showing how — as governor of Roman Britain and commander of the army — he attends to matters of state with fidelity, honesty, and competence, even under the government of the hated Emperor Domitian. Critiques of Domitian and of his regime of spying and repression come to the fore at the work's conclusion. Agricola remained uncorrupted; in disgrace under Domitian, he died without seeking the glory of an ostentatious martyrdom. Tacitus condemns the suicide of the Stoics as of no benefit to the state. Tacitus makes no clear statement as to whether the death of Agricola was from natural causes or ordered by Domitian, although he does say that rumors were voiced in Rome that Agricola was poisoned on the Emperor's orders.
