Other forms: proconsuls
In ancient Rome, the governor of a province was called a proconsul. During wartime, proconsuls had their terms extended beyond the usual year.
Each Roman province had its own proconsul, who was appointed by an elected consul. The word comes from the Latin pro, "in place of," and consul, "magistrate." In ancient Rome, most of these positions were filled by experienced officials who had previously served as consuls. In modern times, proconsul is still used for some officials whose authority is delegated to them by another government official; modern proconsuls often serve as diplomats in foreign countries.
