There were many political leaders including:
-Augustus (First Roman Emperor and founder of the Roman Principate)
-Constantine the Great (First Christian Roman Emperor)
-Trajan (Emperor from 98-117 AD, successful soldier-emperor)
-Nero (the General of the Empire from 38-9 B.C.)
-Gaius Julius Caesar (Dictator of the Roman Republic)
