Cause → Event → Consequence
Caesar's Civil War erupted from the political rivalry between Julius Caesar and Pompey, backed by a majority of the Roman Senate. Pompey commanded a substantially larger army and held the legitimacy of the Republic's institutions, yet his officers pressured him into offering battle despite his reluctance to engage Caesar's seasoned legions.
On 9 August 48 BC, Caesar's veteran legions met Pompey's numerically superior Republican army near Pharsalus in Central Greece. Caesar's forces outmaneuvered and routed Pompey's troops, inflicting an overwhelming defeat. Pompey abandoned his camp disguised as an ordinary citizen and fled the battlefield.
Following his defeat, Pompey sailed to Egypt seeking refuge, but was assassinated upon arrival at the order of Ptolemy XIII. His death effectively dissolved organized senatorial resistance to Caesar, leaving Caesar the dominant power in the Roman world and accelerating the transformation of the Republic toward autocratic rule.
