Augustus was the founder of the Roman Empire and it's first Emperor. He defeated Antony and Cleopatra at the Battle of Actium and became the ruler of Rome. He founded the Principate, which was a system of Monarchy where the Emperor rules for life. He then introduced a program of Reconstruction and Social Reform. Overall, his reign began an era of Pax Romana, or Roman peace. Hope this helps! :)
