43 BC

Year 43 BC was either a common year starting on Sunday, Monday or Tuesday or a leap year starting on Sunday or Monday of the Julian calendar (the sources differ, see leap year error for further information) and a common year starting on Monday of the Proleptic Julian calendar. At the time, it was known as the Year of the Consulship of Pansa and Hirtius (or, less frequently, year 711 Ab urbe condita). The denomination 43 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Roman Republic

Hirtius and Octavian mobilize troops for the march to Mutina, while Pansa continues the levy. Embassy dispatched to treat with Antony.
• January 7 – Octavian is given imperium, marking the start of his public career.
• Marcus Junius Brutus proceeds to secure his position in Thrace and Macedonia. Gaius Cassius Longinus campaigns in Syria and defeats the army of Publius Cornelius Dolabella at Laodicea.
• March – Vibius Pansa set out to link up with Hirtius and Octavian, bringing four legions of recruits, having left one, the legio urbana, to defend Rome.
• April 14 – Battle of Forum Gallorum: Mark Antony, besieging Caesar's assassin Decimus Brutus Albinus in Mutina, defeats the forces of the consul Pansa, but is then immediately defeated by the army of the other consul, Hirtius. Both consuls are killed (Hirtius does not die until after the Battle of Mutina).

He then crosses the Ligurian Alps to Vada Sabatia, Template:Convert south-west of Genoa, and joins with Aemilius Lepidus, soon after Decimus Brutus is killed by brigands. The Senate declares Antony a hostis, an enemy of the state. Sextus Pompey becomes supreme commander of the Roman navy and Gaius Cassius proconsul of Syria.
