Which emperor, born at Italica, fought to conquer Dacia and extended the empire to Parthian territory?

Trajan is recognized for his significant military achievements, particularly the conquest of Dacia, which is present-day Romania. His campaigns, notably the two Dacian Wars (101-102 AD and 105-106 AD), not only expanded the Roman Empire's boundaries but also resulted in substantial economic benefits due to the wealth derived from Dacia's gold mines.

Additionally, Trajan aimed for further expansion into Parthian territory, successfully conducting campaigns that demonstrated his ambition to extend Roman influence beyond the traditional borders of the Empire. His reign marked a high point in the history of Rome, characterized by military success, public building projects, and the expansion of the Empire to its greatest territorial extent.

Each of the other emperors listed had their significant contributions to Roman history but did not match Trajan's specific achievements in terms of military expansion and conquest of Dacia.
