Another office not officially a step in the cursus honorum was the princeps senatus, an extremely prestigious office for a patrician. The princeps senatus served as the leader of the Senate and was chosen to serve a five-year term by each pair of Censors every five years. Censors could, however, confirm a princeps senatus for a period of another five years. The princeps senatus was chosen from all Patricians who had served as a Consul, with former Censors usually holding the office. The office originally granted the holder the ability to speak first at session on the topic presented by the presiding magistrate, but eventually gained the power to open and close the senate sessions, decide the agenda, decide where the session should take place, impose order and other rules of the session, meet in the name of the senate with embassies of foreign countries, and write in the name of the senate letters and dispatches. This office, like the Tribune, did not own imperium, was not escorted by lictors, and could not wear the toga praetexta.
