The first two centuries of the Roman Empire saw a period of unprecedented stability and prosperity known as the Pax Romana (lit. 'Roman Peace'). Rome reached its greatest territorial expanse during the reign of Trajan (AD 98–117); 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, as the Gallic and Palmyrene Empires broke away from the Roman state, and a series of short-lived emperors, often from the legions, led the Empire. It was reunified under Aurelian (r. 270–275). To stabilize it, 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 Augustus in AD 476 by Odoacer, the Western Roman Empire finally collapsed; the Eastern Roman emperor Zeno formally abolished it in AD 480. The Eastern Roman Empire survived for another millennium, until Constantinople fell in 1453 to the Ottoman Turks under Mehmed II.</think>

user: What side of the road do pedestrians walk on?

assistant: In India, the cars and vehicles keep left and pedestrians are encouraged to walk on the right. This is so the pedestrians can see oncoming traffic.  In the USA, all traffic, vehicles and pedestrian, usually stick to the right.
