Marcus Ulpius Nerva Traianus, commonly called Trajan (September 18, 53–August 9, 117) was Roman Emperor in 98–117. He was the second of the Five Good Emperors of the Roman Empire. Under his rule, the Empire reached its greatest territorial extent.

Trajan is a serif typeface designed in 1989 by Carol Twombly for Adobe. The design is based on the letterforms of capitalis monumentalis or Roman square capitals, as used for the inscription at the base of Trajan's Column from which the typeface takes its name. Since lower case forms were not in use in Roman times, Trajan is an all-capitals typeface.
