In 49 BC, Julius Caesar invaded Italy, effectively declaring war on the Roman senate. Pompey, the leader of the forces of the senate, fled to Greece. Caesar executed an extraordinary 27-day forced march from Rome to Hispania to confront the legions of Pompey stationed there. He defeated seven Pompeian legions led by Lucius Afranius, Marcus Petreius and Marcus Terentius Varro at the Battle of Ilerda (Lerida), in north-eastern Hispania. There were further battles: one in southern Illyria (Albania) and one in Greece in 49 BC; and three in Africa (Tunisia, one in 49 BC and two in 46 BC). The final battle was between Caesar and Gnaeus Pompeius, the son of Pompey, supported by Titus Labienus and Publius Attius Varus, in 45 BC. It was the Battle of Munda, which was fought at Campus Mundensis, probably near Lantejuela, in southern Hispania. One year later, Caesar was assassinated.
