Marcus Ulpius Nerva Traianus, commonly known as Trajan (September 18, 53 – August 9, 117), was a Roman Emperor who reigned from 98 until his death in 117.
As a civilian administrator, Trajan is best known for his extensive public building programme, which reshaped the city of Rome and left multiple enduring landmarks such as Trajan’s Forum, Trajan’s Market and Trajan’s Column.
It was as a military commander however that Trajan celebrated his greatest triumphs. In 101, he launched a punitive expedition into the kingdom of Dacia against king Decebalus, defeating the Dacian army near Tapae in 102, and finally conquering Dacia completely in 106. In 107, Trajan pushed further east and annexed the Nabataean kingdom, establishing the province of Arabia Petraea. After a period of relative peace within the Empire, he launched his final campaign in 113 against Parthia, advancing as far as the city of Susa in 116, and expanding the Roman Empire to its greatest extent. During this campaign Trajan was struck by illness, and late in 117, while sailing back to Rome, he died of stroke on August 9, in the city of Selinus.
