Despite his military success, or probably because of it, fear spread of Caesar, now the primary figure of the Roman state, becoming an autocratic ruler and ending the Roman Republic. This fear drove a group of senators naming themselves The Liberators to assassinate him in 44 BC. Further civil war followed between those loyal to Caesar and those who supported the actions of the Liberators. Caesar's supporter Mark Antony condemned Caesar's assassins and war broke out between the two factions. Antony was denounced as a public enemy, and Octavian was entrusted with the command of the war against him. In the Battle of Forum Gallorum Antony, besieging Caesar's assassin Decimus Brutus in Mutina, defeated the forces of the consul Pansa, who was killed, but Antony was then immediately defeated by the army of the other consul, Hirtius. At the Battle of Mutina Antony was again defeated in battle by Hirtius, who was killed. Although Antony failed to capture Mutina, Decimus Brutus was murdered shortly thereafter.
