Final answer:
Mark Antony was loyal to Julius Caesar and worked with Octavian and Lepidus in the Second Triumvirate to defeat Caesar's assassins. He did not attempt to rescind promises in Caesar's will.
Step-by-step explanation:
Among the followers of Julius Caesar, Mark Antony was known for his loyalty and close association with Caesar. After Caesar was assassinated in 44 BCE, Antony did not try to rescind the promises in Caesar's will. Instead, Antony, together with Octavian and Lepidus, formed the Second Triumvirate to defeat Caesar's assassins and secure control over Rome. This alliance would later break down, leading to conflict between Antony and Octavian, with Octavian eventually emerging as the sole leader and the first Emperor of Rome under the name Augustus.
