Trajan, or Marcus Ulpius Traianus, was Roman emperor from 98 to 117 CE. Known as a benevolent ruler, his reign was noted for public projects which benefitted the populace such as improving the dilapidated road system, constructing aqueducts, building public baths and extending the port of Ostia. Trajan was also a highly successful general and won three major conflicts against the Dacians and in the east, resulting in the Roman Empire reaching its greatest size up to that date.
