Who was the twelve-year-old emperor deposed in 476 A.D.?

The twelve-year-old emperor deposed in 476 A.D. was Romulus Augustulus. His reign marked the end of the Western Roman Empire, making him a significant historical figure. Romulus Augustulus was a puppet emperor installed by his father, the military general Orestes, at a time when the power of Rome was declining. His deposition by the Germanic chieftain Odoacer is often seen as a symbolic end to the ancient Roman Empire, as it represented the final fall of the Western Roman authority. The events surrounding his short rule and subsequent ousting are pivotal in understanding the transition from the ancient world to the medieval period. Other figures mentioned, such as Augustus, Julian, and Commodus, relate to different periods and contexts within Roman history and do not correspond to the events surrounding the fall of the Western Roman Empire in 476 A.D.
