The latter part of Marcius’ life was marked by significant achievements. He incorporated several communities into Rome and established Latins in the Janiculum region. This strategic move resulted in an increased Roman population and developed communication between areas on both sides of the river Tiber. He was also recognized for his contribution to Rome’s infrastructure by developing Rome’s first bridge, the Sublician Bridge, which stood as a marvel of innovation.
During his reign, Marcius focused on preserving and strengthening Rome’s military might. He propagated the traditions laid by his predecessor, Numa Pompilius, one being the establishment of religious and legal institutions which cemented Rome’s statehood status. His commitment to consolidating the city’s strength laid foundations for the Roman Empire.
Marcius’ reign ended in unfortunate circumstances around 617 BC, though the specifics surrounding the event remain unclear. According to some accounts, he died in natural circumstances but alternate sources suggest a more tragic demise. Attributed as one of the first noble rulers of Rome, his contributions shaped the course of Roman history and civilization.
