The first one is the answer.
Answer:
Julius Caesar began to reshape the Roman Republic by beginning to give himself authority over certain aspects other officials would get. For example, Caesar gained control of the consul (which were supposed to be two that held the "most" authority), the praetor (which were the replacements of the consuls), and other positions slowly without outright saying he was overruling their authority. He frequently ignored the suggestions of the Senate when it came to war and other affairs, and he basically did as much as he could to gain absolute power without everyone suspecting so. He even declared a civil war against Rome because his enemy, General Pompey, was rivalling his power. I hope this helps, Julius Caesar is a very interesting character!
