History of the Roman Empire

Roman Empire, political system established by Rome that lasted for nearly five centuries. Historians usually date the beginning of the Roman Empire from 27 bc when the Roman Senate gave Gaius Octavius the name Augustus and he became the undisputed emperor after years of bitter civil war. At its peak the empire included lands throughout the Mediterranean world. Rome had first expanded into other parts of Italy and neighboring territories during the Roman Republic (509-27 bc), but made wider conquests and solidified political control of these lands during the empire. The empire lasted until Germanic invasions, economic decline, and internal unrest in the 4th and 5th centuries ad ended Rome’s ability to dominate such a huge territory. The Romans and their empire gave cultural and political shape to the subsequent history of Europe from the Middle Ages and the Renaissance to the present day. In 44 bc Gaius Julius Caesar, the Roman leader who ruled the Roman Republic as a dictator, was assassinated . Rome descended into more than ten years of civil war and political upheaval. After Caesar’s heir Gaius Octavius (also known as Octavian) defeated his last rivals, the Senate in 27 bc proclaimed him Augustus, meaning the exalted or holy one. In this way Augustus established the monarchy that became known as the Roman Empire. The Roman Republic, which had lasted nearly 500 years, was dead, never to be revived. The empire would endure for another 500 years until ad 476 (See Ancient Rome). The emperor Augustus reigned from 27 bc to ad 14 and ruled with absolute power. He reestablished political and social stability and launched two centuries of prosperity called the Roman Peace (Pax Romana). Under his rule the Roman state began its transformation into the greatest and most influential political institution in European history. During the first two centuries ad the empire flourished and added new territories, notably ancient Britain, Arabia, and Dacia (present-day Romania). People from the Roman provinces streamed to Rome, where they became soldiers, bureaucrats, senators, and even emperors. Rome developed into the social, economic, and cultural capital of the Mediterranean world. Despite the attention given to tyrannical and often vicious leaders like the emperors Caligula and Nero, most emperors ruled sensibly and competently until military and economic disasters brought on the political instability of the 3rd century ad. The Roman Empire encompassed a huge amount of territory, but also allowed people of many different cultures to retain their heritage into modern times.
