Maxima auspicia: In ancient Roman religion and law, the auspicia maxima (also "maxima auspicia") were the "greatest auspices," conferred on senior magistrates who held "imperium": ""auspicium" and "imperium" were the twin pillars of the magistrate's power" "(potestas").  Only magistrates who had "auspicia maxima" were entitled to begin a war and, if victorious, to celebrate a triumph.  The "auspicia maxima" were reserved primarily for consuls and censors, but these were two different types of auspices.  Consuls and censors were not colleagues, and the censors lacked military auspices "(auspicia militiae)".  Praetors, however, held a form of "auspicia maxima" and could also lead an army, though their "imperium" was lesser than that of the consuls.

Imperium: Imperium is a Latin word which, in a broad sense, translates roughly as 'power to command'.  In ancient Rome, different kinds of power or authority were distinguished by different terms.  "Imperium" referred to the ability of an individual to command the military.  It is not to be confused with "auctoritas" or "potestas", different and generally inferior types of power in the Roman Republic and Empire.  Primarily used to refer to the power that is wielded, in greater or lesser degree, by an individual to whom it is delegated, the term could also be used with a geographical connotation, designating the territorial limits of that "imperium".  Individuals given such power were referred to as curule magistrates or promagistrates.  These included the curule aedile, the praetor, the consul, the magister equitum, and the dictator.
