Source-derived summary

Trajan ( TRAY-jən; born Marcus Ulpius Traianus, 18 September 53 – c. 9 August 117) was a Roman emperor from AD 98 to 117, remembered as the second of the Five Good Emperors of the Nerva–Antonine dynasty. He was a philanthropic ruler and a successful soldier-emperor who presided over one of the greatest military expansions in Roman history, during which, by the time of his death, the Roman Empire reached its maximum territorial extent. He was given the title of optimus princeps ('the best ruler') by the Roman Senate.

Trajan was born in the municipium of Italica in the present-day Andalusian province of Seville in southern Spain, an Italic settlement in Hispania Baetica; his gens Ulpia came from the town of Tuder in the Umbria region of central Italy. His namesake father, Marcus Ulpius Traianus, was a general and distinguished senator. Trajan rose to prominence during the reign of Domitian; in AD 89, serving as a legatus legionis in Hispania Tarraconensis, he supported the emperor against a revolt on the Rhine led by Antonius Saturninus. He then served as governor of Germania and Pannonia. In September 96, Domitian was succeeded by the elderly and childless Nerva, who proved to be unpopular with the army. After a revolt by members of the Praetorian Guard, Nerva decided to adopt as his heir and successor the more popular Trajan, who had distinguished himself in military campaigns against Germanic tribes.

As emperor of Rome, Trajan oversaw the construction of building projects such as the forum named after him, the expansion of social welfare policies such as the alimenta, and new military conquests.

Editorial summary

Begin with the source’s own compact description: “Trajan” is 13th Roman Emperor (98–117). The dossier treats that line as a proposition to test through Trajan, 13th and Roman, not as a finished interpretation.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current 268-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The authority record carries competing date values—0053, 0053-09, 0053-09-15, 0053-09-18—which should remain separate until their references and qualifiers are resolved. For this dossier, Trajan, 13th and Roman is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “13th Roman Emperor (98–117)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 18, 2026. The linked authority identifier is Q1425. VIAF identifies the subject as 88067472. The Library of Congress control number is n79055990. 7 of 9 selected statements include explicit references; 5 carry qualifiers and 1 use preferred rank.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
