He is remembered as the second of the Five Good Emperors of the Nerva–Antonine dynasty. Trajan 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.Cultural and Linguistic SignificanceThe name Traianus was originally a cognomen, a family name in ancient Rome. It became a given name in later periods, especially in cultures influenced by Roman history. The form Trajan is used in English and other languages to refer to the emperor and as a given name in its own right. The Romanian form Traian is a direct descendant, reflecting the enduring legacy of the emperor in that region.Distribution and VariantsWhile Traianus itself is rare as a modern given name, its variant Trajan is used in various forms across Europe.
