Trajan (Latin: Imperator Caesar Nerva Traianus Divi Nervae filius Augustus; 18 September 53 – 8 August 117) was Roman Emperor from 98 to his death.

Under Trajan's rule, the Roman Empire reached its largest territorial size. He was also in charge of many construction projects in Rome, for which he often employed his favorite architect, Apollodorus of Damascus. One of his construction projects was the Baths of Trajan, which was built atop a section of Nero's ruined Golden Palace, and was poetically intended for use by the commoners. Other projects included a market which, when fully operational, housed no less than 150 shops and offices and a column which commemorated Trajan's victory in the Dacian Wars.
