Caesar's Civil War was a conflict that occurred on Earth-1 in 49 BC due to Julius Caesar's defiance of the Senate's orders.


Prior to 49 BC, Pompey threatened Caesar to have his head cut off if he ever went against the Senate's orders to not march on the Rubicon.

In 49 BC, Caesar and his legion marched on the Rubicon, and the civil war was ignited.[1]

Behind the scenes

  • The Great Roman Civil War (49–45 BC), also known as Caesar's Civil War, was one of the last politico-military conflicts in the Roman Republic before the establishment of the Roman Empire. It began as a series of political and military confrontations, between Julius Caesar (100–44 BC), his political supporters (broadly known as Populares), and his legions, against the Optimates (or Boni), the politically conservative and socially traditionalist faction of the Roman Senate, who were supported by Pompey (106–48 BC) and his legions.
