The beginning of the year in archaic Rome
In the earliest Rome, March 1st traditionally marked the start of the civil year.
This primitive calendar, predating the Julian reform, placed the restart of the annual cycle under the protection of Mars, god of war and symbol of collective renewal.
March was not just a symbolic marker: it indicated the reopening of military activity after the winter and the resumption of administrative and political tasks.
The month's celebrations reflected this practical function.
During the Equirria, horse races linked to military training were held.
The Salii priests would traverse the city with ritual weapons, staging the activation of the military year.
These ceremonies show that the Roman calendar was a state tool that coordinated religion, war, and government. Understanding this framework helps explain why March was a period particularly charged with public decisions.

The Ides of March in the Roman calendar
Within the Roman calendar, the Ides marked a monthly reference point related to administrative adjustments and religious rituals.
In March, the Ides fell on the 15th, at a time when political activity had already fully resumed after the month's initial celebrations.
Senate meetings on these dates were not exceptional.
The calendar organized public time in such a way that politics and religion were intertwined. Therefore, March 15th, 44 BC, was not a casual date: it was an institutionally appropriate day for the presence of magistrates and senators, which allowed a political act of great magnitude to take place within an official setting.
Political context prior to the assassination
Julius Caesar had accumulated unprecedented power after decades of civil wars. His appointment as dictator in perpetuity altered the traditional balance between republican magistracies.
He reformed the Senate, reorganized provinces, and concentrated military and administrative authority.
For part of the senatorial aristocracy, these measures threatened the republican system.
The fear was not just ideological: it implied a loss of political influence and social prestige.
Rome was going through an institutional transition marked by tensions between tradition and the centralization of power.
Ancient sources describe an atmosphere of suspicion and rivalry that facilitated the conspiracy.

The assassination of Julius Caesar: how the attack unfolded
On March 15th, 44 BC, during a session of the Senate held at the Theater of Pompey, a group of conspirators led by Marcus Junius Brutus and Gaius Cassius surrounded Caesar.
According to the accounts of Plutarch and Suetonius, the attack was coordinated to be carried out quickly within a symbolic political space.
Caesar was stabbed repeatedly in front of the senators present.
The choice of location reinforced the message that the act was presented as an intervention in defense of the Republic. However, far from restoring stability, the assassination opened a new phase of political violence.
Immediate consequences and institutional transformation
After Caesar's death, Rome entered another civil war.
The Caesarean supporters, led by Mark Antony and Octavian, clashed with the republican conspirators.
The prolonged conflict definitively weakened the traditional structures.
In 27 BC, Octavian assumed the title of Augustus, establishing the Principate.
This process was not immediate, but the result of years of political reorganization.
The assassination in March acted as the trigger for the transformation that led to the formal end of the Republic.
