Who was Octavain?

Answer 1

The man we know as Octavian was Julius Caesar's adopted son and heir. He was a master politician, a military victor, and became the sole ruler of Rome, changing the government from republic to principate. He was voted the title "Augustus" by the senate and from that time on he was known as Caesar Augustus or simply Augustus. He is sometimes referred to as the first Roman emperor by historians, although the Romans never used the word "emperor".

Octavian was the successor of Julius Caesar, and the first emperor of Rome.
