The Roman Empire (Latin: Imperium Rōmānum, Classical Latin: [ɪmˈpɛrɪ.ũː roːˈmaːnũː]; Koinē Greek: Βασιλεία τῶν Ῥωμαίων, romanized: Basileía tōn Rhōmaíōn) was the post-Republican period of ancient Rome. As a polity it included large territorial holdings around the Mediterranean Sea in Europe, North Africa and West Asia ruled by emperors. From the accession of Caesar Augustus to the military anarchy of the third century, it was a principate with Italy as metropole of the provinces and its city of Rome as sole capital (27 BC – 286 AD). Although fragmented briefly during the military crisis, the empire was forcibly reassembled, then ruled by multiple emperors who shared rule over the Western Roman Empire (based in Milan and later in Ravenna) and over the Eastern Roman Empire (based in Nicomedia and later in Constantinople). Rome remained the nominal capital of both parts until 476 AD, when it sent the imperial insignia to Constantinople (Byzantium - Ancient Greek: Βυζάντιον, Byzántion) following the capture of Ravenna by the barbarians of Odoacer and the subsequent deposition of Romulus Augustus. The fall of the Western Roman Empire to Germanic kings, along with the hellenization of the Eastern Roman Empire into the Byzantine Empire, conventionally marks the end of Ancient Rome and the beginning of the Middle Ages.
The predecessor state of the Roman Empire, the Roman Republic (which had replaced Rome's monarchy in the 6th century BC) became severely destabilized in a series of civil wars and political conflicts. In the mid-1st century BC Julius Caesar was appointed as perpetual dictator and then assassinated in 44 BC. Civil wars and proscriptions continued, culminating in the victory of Octavian, Caesar's adopted son, over Mark Antony and Cleopatra at the Battle of Actium in 31 BC. The following year Octavian conquered Ptolemaic Egypt, ending the Hellenistic period that had begun with the conquests of Alexander the Great of Macedon in the 4th century BC. Octavian's power then became unassailable, and in 27 BC the Roman Senate formally granted him overarching power and the new title Augustus, effectively making him the first Roman emperor.
The first two centuries of the Empire saw a period of unprecedented stability and prosperity known as the Pax Romana ("Roman Peace"). Rome reached its greatest territorial expanse during the reign of Trajan (98–117 AD). A period of increasing trouble and decline began with the reign of Commodus (177-192). In the 3rd century the Empire underwent a crisis that threatened its existence, but was reunified under Aurelian (r. 270–275). In an effort to stabilize the Empire, Diocletian set up two different imperial courts in the Greek East and Latin West in 286. Christians rose to positions of power in the 4th century following the Edict of Milan of 313. Shortly after, the Migration Period, involving large invasions by Germanic peoples and by the Huns of Attila, led to the decline of the Western Roman Empire. With the fall of Ravenna to the Germanic Herulians and the deposition of Romulus Augustulus in 476 AD by Odoacer, the Western Roman Empire finally collapsed - the (Eastern Roman) Emperor Zeno formally abolished it in 480 AD. The Eastern Roman Empire, identified by modern historians under the name of the Byzantine Empire, survived for another millennium until the Empire's last remains collapsed when Constantinople fell to the Ottoman Turks of Sultan Mehmed II in 1453. (The Ottomans sometimes called their state the "Empire of Rûm" (Ottoman Turkish: دولت علنإه روم, lit. 'Exalted State of Rome'). In this sense, a "Roman" Empire survived until the early-20th century
