Secretariat
In the early years of his reign, Claudius organized imperial secretariat, which established four panel, headed by set of loyal freedmen. This was due to the relations between the emperor and nobility, including the Senate. Claudius simply could not trust people from the higher of the Roman world.
College was led by: Tiberius Claudius Narcissus, was promoted to Secretary-General (responsible for correspondence), Mark Anthony Pallas took the post of treasurer, Julius Callistus was headed by a panel of science and justice, but for everything else replied Gaius Julius Polybius. As shown by name, Narcissus was a freedman of Claudius himself, Callistus and Polybius their freedom during the reign of Caligula, and Pallas belonged to Antonia Minor and was released during the time of Tiberius.
This decision allowed her out in a short time enough to consolidate its power, despite the opposition of Senators who are dissatisfied with this state of affairs. In the hands of people were loyal to the emperor money, law, legislation, army. They advised her out of some people as the legates of the legions, they are also obliged to Claudius the idea of the victorious British campaign, greatly increased his popularity and strengthened his position.
Naturally, having such authority, all four have used it not only for the benefit of the state, but also for personal enrichment. According to Pliny, some of them were richer than most of Crassus, the richest of the Romans, who lived at the time of Julius Caesar.
