Answer:
As the first Roman emperor (though he never claimed the title for himself), Augustus led Rome’s transformation from republic to empire during the tumultuous years following the assassination of his great-uncle and adoptive father Julius Caesar. He shrewdly combined military might, institution-building and lawmaking to become Rome’s sole ruler, laying the foundations of the 200-year Pax Romana (Roman Peace) and an empire that lasted, in various forms, for nearly 1,500 years.
