While the Senate as a body was thus stripped of its power, the senatorial order remained a powerful class. Originally embracing the chief landholders of Italy, it came to include those of the whole empire. Collectively the senators lost in influence, but individually they gained. By the end of the second century the senatorial order had acquired an hereditary title, that of _clarissimus_ (most noble), indicative of their rank. II. THE GROWTH OF THE CIVIL SERVICE *The first steps.* The necessary counterpart to the assumption of administrative duties by the princeps was the development of an imperial civil service, the officials of which were nominated by the princeps, and promoted or removed at his pleasure. In this Augustus had taken the first steps by the establishment of equestrian procuratorships and prefectures, and the opening up of an equestrian career, but the number of these posts greatly increased with the extension of the administrative sphere of the princeps at the expense of the Senate. The idea of conducting the government through various departments manned by permanent salaried officials was absolutely foreign to the Roman republic, which only employed such servants for clerical positions of minor importance in Rome. However, the chaotic conditions which had resulted from the republican system showed the need of a change, and the concentration of a large share of the administration in the hands of the princeps both required and gave the opportunity for the development of an organized civil service. This development was unquestionably stimulated and influenced by the incorporation in the Roman empire of the kingdom of Egypt, which possessed a highly organized bureaucratic system that continued to function unchanged in its essential characteristics.
