I want to know the answer to the following question:
In what year was Octavian first allowed to use the names Augustus and Princeps?
All the background I'm provided with is that "In 27 BC Octavian was granted the use of the names "Augustus" and "Princeps", indicating his primary status above all other Romans, and he adopted the title "Imperator Caesar" making him the first Roman Emperor.". Is that enough to answer the question?
Answer: yes
