Julius Caesar came to sole power by defeating Pompey and the senators who endorsed him.
Julius Caesar with Crassus and Pompey established a political alliance in 60 BC. After this, Caesar became victorious in the wars and invades territories. He then achieved an unmatched military power. Pompey, on the other hand went over to the senate after Crassus’ death and the Senate ordered Caesar to surrender his military power and return to Rome. Caesar refused and won the civil war which made him to power.
