Final answer:
Octavian's political and military success owed much to Julius Caesar's legacy, such as his name and alliances, yet Octavian's own political skill and military victories were critical in establishing his autocratic rule. Augustus leveraged cultural programs to maintain public favor.
Step-by-step explanation:
The question seems to pertain to the historical figure Octavian, also known as Augustus, who was the adopted son and successor of Julius Caesar. As such, the answer to the question about the extent to which Octavian's political and military successes were due to Julius Caesar's achievements can be quite complex. Octavian inherited a powerful name and a network of allies and veterans from Caesar, which laid a strong foundation for his future successes. However, Octavian, through his own savvy political maneuvers, strategic marriages, and military victories, including his triumph in the final war of the Roman Republic, solidified his power and established the Roman Empire. Augustus' rule is also marked by his shrewd use of culture and public spectacle to appease and distract the populace, including lavish expenditures on public festivals, as cited from Cassius Dio's account.
