Trajan’s Column was built around 100 AD to commemorate the emperor Trajan’s military successes and to instill a sense of trust in him as emperor. Trajan’s column marked the entrance into the massive Trajan’s Forum or Market. This signifies to visitors that Rome’s empire and economy was growing to the point that Rome had a use for such a large market for public commerce, which was made possible by the military conquests of Rome’s emperors. The column was a war trophy that depicted Trajan’s military conquest of Dacis. It was used as political propaganda to assert his claim to power and to gain trust and support from the people of Rome. This column explains in its reliefs why Trajan is important and why he deserves power and responsibility. Although previously topped by a statue of Trajan himself, it is currently topped by a statue of St. Peter to signify a new empire headed by the Catholic Church under the authority of the saints. This new empire is also signified by the grandeur of Vatican City and other Christian monuments throughout the city. Trajan’s column shows the link between military success and political capabilities as assumed by Roman emperors. This idea is also supported by the Marcus Aurelius Column which is also used as political propaganda to draw support for the emperor.
