Founding of the Roman Republic and Consulship Established
In 509 BCE, Romans expelled their kings and replaced a single crown with two annually elected consuls. The change was more than a swap of rulers; it recast power as a public trust—timed, shared, and answerable in the Forum. Bronze axes gleamed on the lictors’ fasces, but the sharpest edge was the calendar: twelve months and you were out.
What Happened
Livy’s first sentence says it in hard Latin: kings once held Rome; liberty and the consulship were the work of Lucius Brutus. That memory—of a city breathing again after monarchy—lived in the stones of the Forum Romanum, in the Curia Hostilia on the north side, and along the Sacred Way to the Capitoline Hill. In the winter of 509 BCE, a single voice was deliberately split into two.
Two consuls, elected for one year, took the highest imperium. Not one man, two. Not for life, for twelve months. Each kept 12 lictors, their fasces bound with scarlet bands, the axes glinting bronze outside the pomerium. And each could stop the other with a word—intercessio—so that ambition met its mirror before it met the people [16,18].
The change reorganized sound as much as law. Instead of a king’s command echoing through the Comitium, you heard ballots rattle and the crier’s voice carry across the Tiber River. The Comitia Centuriata—massed by centuries of wealth and age—chose the consuls in painstaking order, century by century [18]. On election day, the field outside the city, the Campus Martius, buzzed with shouts and the clack of lots.
Magistrates now moved in a harness. Collegiality bound each officeholder to a peer; annual tenure bound him to time; post‑magistracy trials bound him to the people. The senate—an aristocratic council of former magistrates—advised in the Curia, steered foreign affairs, and guarded the treasury on the Capitoline [16]. The whole system performed a simple trick: it made power noisy and visible.
Even custom—mos maiorum—became a brake. The consuls alternated days of precedence; they wore the purple‑bordered toga praetexta but stepped down from their curule chairs to face litigants and allies. When they marched, the clatter of shields on the Via Latina reminded everyone that imperium meant both court and camp. But when their term ended, they returned to the Forum as private men, answerable for what they had done.
A republic needs rituals. The consulship took shape in them: New Year vows at the Temple of Jupiter Optimus Maximus, the census cycle under later censors, the right of citizens to appeal (provocatio) against coercion. Rome made liberty routine. By design, no one man’s voice dominated the city’s stones for long [16,18].
Why This Matters
The decision to split and limit executive power recalibrated the entire political physics of Rome. Two consuls, one year, mutual veto: these rules made individual dominance difficult and forced negotiation in public. The senate gained a stage to advise; the assemblies retained the power to choose and to judge. Power became a performance under law instead of a possession.
This new arrangement embodies the theme of a mixed constitution. Consuls provided monarchical energy when armies marched, the senate offered aristocratic continuity in policy, and assemblies announced the democratic will in elections and trials. Annuality, collegiality, and accountability formed a triad of checks that later magistracies—praetors, aediles, quaestors, and tribunes—would replicate [16,18].
The consulship also set up later crises. Because imperium included military command, success in the field could translate into political muscle back in Rome. As the Republic expanded, commanders carried legions farther from the Forum, and the question crept in: would soldiers listen to ballots they could not hear? That tension surfaces from the Gracchi to Sulla to Caesar.
Historians linger on 509 BCE because it frames Roman libertas as institutional habit, not just sentiment. The consulship’s design—shared, brief, and reversible—became a model for later republican thought. And when Augustus took power in 27 BCE, he borrowed the consul’s symbols while emptying their competition of real bite, reminding us that forms can survive while functions shift [16,18].
