Step-by-step explanation:
In his will, Julius Caesar left a significant portion of his vast wealth to the people of Rome. While the exact proportion is not detailed in the provided references, it is known that Caesar's bequest had a strong impact on the Roman populace and contributed to his lasting legacy. Caesar's heir and grand-nephew, Octavian, who later became Augustus, the first Roman Emperor, was left with almost all of Caesar's wealth, which came as a surprise to many. Despite the senators' resentment towards Caesar's power, his gestures to support the common people, such as his agrarian laws distributing public land and his venations and stage-plays, had solidified his popularity.
While the texts do not provide a specific figure or percentage, it is known that Caesar used his wealth and resources to provide public games and support the establishment of military colonies, which served as dual-purpose measures that also ensured the loyalty of his troops. His actions as a public figure demonstrated an understanding of the importance of popular favor and provided him with a platform to exercise his influence over the Roman state, ultimately setting the stage for his adopted heir Octavian to continue his legacy.
