Final answer:
Julius Caesar was an army commander and a dictator during the late Roman Republic, who played a significant role in its transformation into the Roman Empire. His permanent dictatorship and military successes made him a central figure in Roman history.
Step-by-step explanation:
The descriptions true about Julius Caesar are that he was both an army commander and a dictator. As a statesman and commander, he played a pivotal role in the events leading to the end of the Roman Republic and the rise of the Roman Empire. Caesar indeed waged civil war against the Roman Senate, defeated the patrician conservatives, and declared himself dictator, an appointment that eventually became permanent until his assassination in 44 BCE. Despite some opposition considering him a tyrant, Caesar's various titles and roles, including praetor, consul, and augur, indicate his central involvement in Roman military, political, and religious leadership.
