Romulus Augustulus is often given as the last Roman emperor in the West, and 476 as the date of the extinction of the empire, but Romulus was a puppet installed by his father Orestes, and was never recognized by Constantinople, which continued to support Julius Nepos. When the Germanic ruler Odoacer deposed Romulus he allowed Julius to remain as nominal emperor in Dalmatia.
