 As he had in 411 BC, Theramenes soon came into conflict with the more extreme members of that government; his protests against the reign of terror the Thirty implemented led the leading oligarchs to plot his demise; he was denounced before the oligarchic assembly, and then, when that body appeared reluctant to punish him, struck him from the roster of citizens and executed him without trial.Theramenes remained a controversial figure after his death; Lysias vigorously denounced him while prosecuting several of his former political allies, but others defended his actions.Modern historical assessments have shifted over time; in the 19th century, Theramenes's part in the coup of 411 BC and his use of Arginusae were widely condemned, but newly discovered ancient texts and 20th-century scholarship supported more positive assessments.
