Although in his youth Titus Labienus was considered unimportant, as an adult he garnered fame for his works as an historian and orator and has come to be regarded as one of the most instrumental and important historians of all time. At the time, Rome was a new monarchy, Augustus had assumed power, and there was a lot of animosity in the air between the people who were for and those who were against the monarchy that had taken over the Roman Empire. Continuously, people would go throughout the city of Rome and either publicly state or publish pamphlets with negative comments and accusations about the new emperor and monarchy. Titus Labienus eagerly joined the cause against the new monarchy, "flailing Augustan order" and vigorously supported Pompey the Great (106 BC to 46 BC), a statesman and general of the late Roman Republic and opponent of Julius Caesar for forming the monarchy.
