Final answer:
Caesar's conquest of Gaul, wealth accumulation, victories in civil wars, and reputation as a great military general helped him rise to power and earn plebeian support.
Step-by-step explanation:
Julius Caesar's military successes were instrumental in his rise to power. Firstly, he won the civil wars, which not only gave him an upper hand against the patricians but also established his military prowess. Secondly, his conquest of Gaul brought great wealth and resources under Roman control, which he used to garner influence and support. His actions during the civil wars endeared him to the plebeians, who saw him as a champion of their cause against the aristocratic senate. Moreover, Caesar's victories and the sheer number of battles he won earned him a reputation as one of the greatest military generals of his time, which increased his authority and popularity, aiding his ascent to power.
