In 55, Nero added the cities of Tiberias and Taricheae in Galilee, and Julias, with fourteen villages near it, in Peraea. Agrippa expended large sums in beautifying Jerusalem and other cities, especially Berytus. His partiality for the latter rendered him unpopular amongst his own subjects, and the capricious manner in which he appointed and deposed the high priests made him an object of dislike to the Jews. Agrippa attempted in vain to dissuade his subjects from rebelling, and to tolerate the behavior of the Roman procurator Gessius Florus, but in 66 the Jews expelled him and Berenice from the city. During the First Jewish-Roman War of 66–73, he sent 2,000 men, archers and cavalry, to support Vespasian, by which it appears that, although a Jew in religion, he was yet entirely devoted to the Romans. He accompanied Titus on some campaigns, and was wounded at the siege of Gamala. After the capture of Jerusalem, he went with his sister Berenice to Rome, where he was invested with the dignity of praetor and rewarded with additional territory.
According to Photius, Agrippa died, childless, at the age of seventy, in the third year of the reign of Trajan, that is, 100, but statements of Josephus in addition to the contemporary epigraphy from his kingdom cast this date into serious doubt. The modern scholarly consensus holds that he died before 93/94. He was the last prince of the house of the Herods.
It was before him and his sister Berenice that, according to the New Testament, Paul the Apostle pleaded his cause at Caesarea Maritima, in 59.
He lived on terms of intimacy with the historian Josephus, having supplied him with information for his history, Antiquities of the Jews. Josephus preserved two of the letters he received from him.
