The Roman triumph () was a civil ceremony and religious rite of ancient Rome, held to publicly celebrate and sanctify the success of a military commander who had led Roman forces to victory in the service of the state or, originally and traditionally, one who had successfully completed a foreign war.
On the day of his triumph, the general wore a crown of laurel and the all-purple, gold-embroidered triumphal toga picta ("painted" toga), regalia that identified him as near-divine or near-kingly, and even was known to paint his face red. He rode in a four-horse chariot through the streets of Rome in unarmed procession with his army, captives, and the spoils of his war. At Jupiter's temple on the Capitoline Hill, he offered sacrifice and the tokens of his victory to the god. Republican morality required that, despite these extraordinary honours, the general conduct himself with dignified humility, as a mortal citizen who triumphed on behalf of Rome's Senate, people, and gods. Inevitably, the triumph offered extraordinary opportunities for self-publicity, besides its religious and military dimensions. Most Roman festivals were calendar fixtures, while the tradition and law which reserved a triumph to extraordinary victory ensured that its celebration, procession, attendant feasting, and public games promoted the general's status and achievement. By the Late Republican era, triumphs were drawn out and extravagant, motivated by increasing competition among the military-political adventurers who ran Rome's nascent empire, in some cases prolonged by several days of public games and entertainments. From the Principate onwards, the triumph reflected the Imperial order and the pre-eminence of the Imperial family.
The triumph was consciously imitated by medieval and later states in the royal entry and other ceremonial events.
In Republican Rome, truly exceptional military achievement merited the highest possible honours, which connected the vir triumphalis ("man of triumph", later known as a triumphator) to Rome's mythical and semi-mythical past. In effect, the general was close to being "king for a day", and possibly close to divinity. He wore the regalia traditionally associated both with the ancient Roman monarchy and with the statue of Jupiter Capitolinus: the purple and gold "toga picta", laurel crown, red boots and, again possibly, the red-painted face of Rome's supreme deity. He was drawn in procession through the city in a four-horse chariot, under the gaze of his peers and an applauding crowd, to the temple of Capitoline Jupiter. The spoils and captives of his victory led the way; his armies followed behind. Once at the Capitoline temple, he sacrificed two white oxen to Jupiter and laid tokens of his victory at Jupiter's feet, dedicating his victory to the Roman Senate, people, and gods.
