Chariot racing (Greek: ἁρματοδρομία harmatodromia, Latin: ludi circenses) was one of the most popular ancient Greek, Roman, and Byzantine sports. Chariot racing was often dangerous to both driver and horse as they frequently suffered serious injury and even death, but generated strong spectator enthusiasm. In the ancient Olympic Games, as well as the other Panhellenic Games, the sport was one of the most important equestrian events.Each chariot was pulled by 4 horses.
In the Roman form of chariot racing, teams represented different groups of financial backers and sometimes competed for the services of particularly skilled drivers. These teams became the focus of intense support among spectators, and occasional disturbances broke out between followers of different factions. The conflicts sometimes became politicized, as the sport began to transcend the races themselves and started to affect society overall. This helps explain why Roman and later Byzantine emperors took control of the teams and appointed many officials to oversee them.
The sport faded in importance after the fall of Rome in the West, surviving only for a time in the Byzantine Empire, where the traditional Roman factions continued to play a prominent role for some time, gaining influence in political matters. Their rivalry culminated in the Nika riots, which marked the gradual decline of the sport.
Ancient Greece 
Early chariot racing 
It is unknown exactly when chariot racing began, but it may have been as old as chariots themselves. It is known from artistic evidence on pottery that the sport existed in the Mycenaean world, but the first literary reference to a chariot race is the one described by Homer, at the funeral games of Patroclus. The participants in this race were Diomedes, Eumelus, Antilochus, Menelaus, and Meriones. The race, which was one lap around the stump of a tree, was won by Diomedes, who received a slave woman and a cauldron as his prize. A chariot race was also said to be the event that founded the Olympic Games; according to one legend, mentioned by Pindar, King Oenomaus challenged his daughter Hippodamia's suitors to a race, but was defeated by Pelops, who founded the Games in honour of his victory.
Olympic Games 
In the ancient Olympic Games, as well as the other Panhellenic Games, there were both four-horse (tethrippon, Greek: τέθριππον) and two-horse (synoris, Greek: ξυνωρὶς) chariot races, which were essentially the same aside from the number of horses. The chariot racing event was first added to the Olympics in 680 BC with the games expanding from a one-day to a two-day event to accommodate the new event (but was not, in reality, the founding event). The chariot race was not as prestigious as the stadion (the foot race), but it was more important than other equestrian events such as racing on horseback, which were dropped from the Olympic Games very early on.
The races themselves were held in the hippodrome, which held both chariot races and riding races. The single horse race was known as the "keles". The hippodrome was situated at the south-east corner of the sanctuary of Olympia, on the large flat area south of the stadium and ran almost parallel to the latter. Until recently, its exact location was unknown, since it is buried by several meters of sedimentary material from the Alfeios River. In 2008, however, Norbert Muller and staff of the German Archeological Institute used radar to locate a large, rectangular structure similar to Pausanias's description. Pausanias, who visited Olympia in the second century BC, describes the monument as a large, elongated, flat space, approximately 780 meters long and 320 meters wide (four stadia long and one stadefour plethra wide). The elongated racecourse was divided longitudinally into two tracks by a stone or wooden barrier, the embolon. All the horses or chariots ran on one track towards the east, then turned around the embolon and headed back west. Distances varied according to the event. The racecourse was surrounded by natural (to the north) and artificial (to the south and east) banks for the spectators; a special place was reserved for the judges on the west side of the north bank.
The race was begun by a procession into the hippodrome, while a herald announced the names of the drivers and owners. The tethrippon consisted of twelve laps around the hippodrome, with sharp turns around the posts at either end. Various mechanical devices were used, including the starting gates (hyspleges, singular: hysplex, Greek: ὕσπληγξ-ὕσπληγγες) which were lowered to start the race. According to Pausanias, these were invented by the architect Cleoitas, and staggered so that the chariots on the outside began the race earlier than those on the inside. The race did not actually begin properly until the final gate was opened, at which point each chariot would be more or less lined up alongside each other, although the ones that had started on the outside would have been travelling faster than the ones in the middle. Other mechanical devices known as the "eagle" and the "dolphin" were raised to signify that the race had begun, and were lowered as the race went on to signify the number of laps remaining. These were probably bronze carvings of those animals, set up on posts at starting line.
In most cases, the owner and the driver of the chariot were different persons. In 416 BC, the Athenian general Alcibiades had seven chariots in the race, and came in first, second and fourth; obviously, he could not have been racing all seven chariots himself. Philip II of Macedon also won an Olympic chariot race in an attempt to prove he was not a barbarian, though if he had driven the chariot himself he would likely have been considered even lower than a barbarian. However, the poet Pindar did praise the courage of Herodotos of Thebes for driving his own chariot. This rule also meant that women could technically win the race, despite the fact that women were not allowed to participate in or even watch the Games. This happened rarely, but a notable example is the Spartan Cynisca, daughter of Archidamus II, who won the chariot race twice. Chariot racing was a way for Greeks to demonstrate their prosperity at the games. The case of Alcibiades indicates also that chariot racing was an alternative route to public exposure and fame for the wealthy.
The charioteer was usually a family member of the owner of the chariot or, in most cases, a slave or a hired professional (driving a racing chariot required unusual strength, skill, and courage). Yet, we know the names of very few charioteers, and victory songs and statues regularly contrive to leave them out of account. Unlike the other Olympic events, charioteers did not perform in the nude, probably for safety reasons because of the dust kicked up by the horses and chariots, and the likelihood of bloody crashes. Racers wore a sleeved garment called a xystis. It fell to the ankles and was fastened high at the waist with a plain belt. Two straps that crossed high at the upper back prevented the xystis from "ballooning" during the race.
The chariots themselves were modified war chariots, essentially wooden carts with two wheels and an open back, although chariots were by this time no longer used in battle. The charioteer's feet were held in place, but the cart rested on the axle, so the ride was bumpy. The most exciting part of the chariot race, at least for the spectators, was the turns at the ends of the hippodrome. These turns were very dangerous and often deadly. If a chariot had not already been knocked over by an opponent before the turn, it might be overturned or crushed (along with the horses and driver) by the other chariots as they went around the post. Deliberately running into an opponent to cause him to crash was technically illegal, but nothing could be done about it (at Patroclus' funeral games, Antilochus in fact causes Menelaus to crash in this way), and crashes were likely to happen by accident anyway.
Other great festivals 
As a result of the rise of the Greek cities of the classic period, other great festivals emerged in Asia Minor, Magna Graecia, and the mainland providing the opportunity for athletes to gain fame and riches. Apart from the Olympics, the best respected were the Isthmian Games in Corinth, the Nemean Games, the Pythian Games in Delphi, and the Panathenaic Games in Athens, where the winner of the four-horse chariot race was given 140 amphorae of olive oil (much sought after and precious in ancient times). Prizes at other competitions included corn in Eleusis, bronze shields in Argos, and silver vessels in Marathon. Another form of chariot racing at the Panathenaic Games was known as the apobatai, in which the contestant wore armor and periodically leapt off a moving chariot and ran alongside it before leaping back on again. In these races, there was a second charioteer (a "rein-holder") while the apobates jumped out; in the catalogues with the winners both the names of the apobates and of the rein-holder are mentioned. Images of this contest show warriors, armed with helmets and shields, perched on the back of their racing chariots. Some scholars believe that the event preserved traditions of Homeric warfare.
Roman era 
The Romans probably borrowed chariot racing from the Etruscans, who themselves borrowed it from the Greeks, but the Romans were also influenced directly by the Greeks. According to Roman legend, chariot racing was used by Romulus just after he founded Rome in 753 BC as a way of distracting the Sabine men. Romulus sent out invitations to the neighbouring towns to celebrate the festival of the Consualia, which included both horse races and chariot races. Whilst the Sabines were enjoying the spectacle, Romulus and his men seized and carried off the Sabine women, who became wives of the Romans. Chariot races were a part of several Roman religious festivals, and on these occasions were preceded by a parade (pompa circensis) that featured the charioteers, music, costumed dancers, and images of the gods. While the entertainment value of chariot races tended to overshadow any sacred purpose, in late antiquity the Church Fathers still saw them as a traditional "pagan" practice, and advised Christians not to participate.
In ancient Rome, chariot races commonly took place in a circus. The main centre of chariot racing was the Circus Maximus in the valley between Palatine Hill and Aventine Hill, which could seat 250,000 people. It was the earliest circus in the city of Rome. The Circus was supposed to date to the city's earliest times, but it was rebuilt by Julius Caesar around 50 BC so that it had a length of about 650 metres (2,130 ft) and a width of about 125 metres (410 ft). One end of the track was more open than the other, as this was where the chariots lined up to begin the race. The Romans used a series of gates known as carceres, an equivalent to the Greek hysplex. These were staggered in the same way as the hysplex, but they were slightly different because Roman racing tracks also had a median (the spina) in the centre of the track. The carceres took up the angled end of the track, and the chariots were loaded into spring-loaded gates. When the chariots were ready, the emperor (or whoever was hosting the races, if they were not in Rome) dropped a cloth known as a mappa, signalling the beginning of the race. The gates would spring open, creating a perfectly fair beginning for all participants.
Once the race had begun, the chariots could move in front of each other in an attempt to cause their opponents to crash into the spinae (singular spina). On the top of the spinae stood small tables or frames supported on pillars, and also small pieces of marble in the shape of eggs or dolphins. The spina eventually became very elaborate, with statues and obelisks and other forms of art, but the multiplication of the adornments of the spina had one unfortunate result: They became so numerous that they obstructed the view of spectators on lower seats. At either end of the spina was a meta, or turning point, in the form of large gilded columns. Spectacular crashes took place there, as in the Greek races, in which the chariot was destroyed and the charioteer and horses incapacitated were known as naufragia, also the Latin word for shipwrecks.
The race itself was much like its Greek counterpart, although there were usually 24 races every day that, during the fourth century, took place on 66 days each year. However, a race consisted of only 7 laps (and later 5 laps, so that there could be even more races per day), instead of the 12 laps of the Greek race. The Roman style was also more money-oriented; racers were professionals and there was widespread betting among spectators. There were four-horse chariots (quadrigae) and two-horse chariots (bigae), but the four-horse races were more important. In rare cases, if a driver wanted to show off his skill, he could use up to 10 horses, although this was extremely impractical.
The technique and clothing of Roman charioteers differed significantly from those used by the Greeks. Roman drivers wrapped the reins round their waist, while the Greeks held the reins in their hands. Because of this, the Romans could not let go of the reins in a crash, so they would be dragged around the circus until they were killed or they freed themselves. In order to cut the reins and keep from being dragged in case of accident, they carried a falx, a curved knife. They also wore helmets and other protective gear. In any given race, there might be a number of teams put up by each faction, who would cooperate to maximize their chances of victory by ganging up on opponents, forcing them out of the preferred inside track or making them lose concentration and expose themselves to accident and injury. Spectators could also play a part as there is evidence they threw lead "curse" amulets studded with nails at teams opposing their favourite.
Another important difference was that the charioteers themselves, the aurigae, were considered to be the winners, although they were usually also slaves (as in the Greek world). They received a wreath of laurel leaves, and probably some money; if they won enough races they could buy their freedom. Drivers could become celebrities throughout the Empire simply by surviving, as the life expectancy of a charioteer was not very high. One such celebrity driver was Scorpus, who won over 2000 races before being killed in a collision at the meta when he was about 27 years old. The most famous of all was Gaius Appuleius Diocles who won 1,462 out of 4,257 races. When Diocles retired at the age of 42 after a 24 year career his winnings reportedly totalled 35,863,120 sesterces ($US 15 billion), making him the highest paid sports star in history. The horses, too, could become celebrities, but their life expectancy was also low. The Romans kept detailed statistics of the names, breeds, and pedigrees of famous horses.
Seats in the Circus were free for the poor, who by the time of the Empire had little else to do, as they were no longer involved in political or military affairs as they had been in the Republic. The wealthy could pay for shaded seats where they had a better view, and they probably also spent much of their times betting on the races. The circus was the only place where the emperor showed himself before a populace assembled in vast numbers, and where the latter could manifest their affection or anger. The imperial box, called the pulvinar in the Circus Maximus, was directly connected to the imperial palace.
The driver's clothing was color-coded in accordance with his faction, which would help distant spectators to keep track of the race's progress. According to the disapproving Tertullian, there were originally just two factions, White and Red, sacred to winter and summer respectively. As fully developed, there were four factions, the Red, White, Green, and Blue. Each team could have up to three chariots each in a race. Members of the same team often collaborated with each other against the other teams, for example to force them to crash into the spina (a legal and encouraged tactic). Drivers could switch teams, much like athletes can be traded to different teams today.
By 77 BC, the rivalry between the Red and the Whites was already developed, when a funeral for a Red driver involved a Red supporter throwing himself on the funeral pyre. No writer of the time, however, refers to these as factions such as came into existence later, with the factions being official organizations. Writing near the beginning of the third century, he wrote that the Reds were dedicated to Mars, the Whites to the Zephyrs, the Greens to Mother Earth or spring, and the Blues to the sky and sea or autumn. Domitian created two new factions, the Purples and Golds, which disappeared soon after he died. The Blues and the Greens gradually became the most prestigious factions, supported by emperor and populace alike. Numerous occasions occurred when a Blue vs. Green clash would break out during a race. Indeed, Reds and Whites are only rarely mentioned in the surviving literature, although their continued activity is documented in inscriptions and in curse-tablets.
Byzantine era 
Like many other aspects of the Roman world, chariot racing continued in the Byzantine Empire, although the Byzantines did not keep as many records and statistics as the Romans did. In place of the detailed inscriptions of Roman racing statistics, several short epigrams in verse were composed celebrating some of the more famous Byzantine Charioteers. The six charioteers about whom these laudatory verses were written were Anastasius, Julianus of Tyre, Faustinus, his son, Constantinus, Uranius, and Porphyrius. Although Anastasius's single epigram reveals almost nothing about him, Porphyrius is much better known, having thirty-four known poems dedicated to him.
Constantine I (r. 306–337) preferred chariot racing to gladiatorial combat, which he considered a vestige of paganism. However, the end of gladiatorial games in the Empire may have been more the result of the difficulty and expense that came with procuring gladiators to fight in the games, than the influence of Christianity in Byzantium. The Olympic Games were eventually ended by Emperor Theodosius I (r. 379–395) in 393, perhaps in a move to suppress paganism and promote Christianity, but chariot racing remained popular. The fact that chariot racing became linked to the imperial majesty meant that the Church did not prevent it, although gradually prominent Christian writers, such as Tertullian, began attacking the sport. Despite the influence of Christianity in the Byzantine Empire, venationes, bloody wild-beast hunts, continued as a form of popular entertainment during the early days of the Empire as part of the extra entertainment that went along with chariot racing. Eventually, Emperor Leo (r. 457–474) banned public entertainments on Sundays in 469, showing that the hunts did not have imperial support, and the venationes were banned completely by Emperor Anastasius (r. 491–518) in 498. Anastasius was praised for this action by some sources, but their concern seems to be more for the danger the hunts could put humans in rather than for objections to the brutality or moral objections. There continued to be burnings and mutilations of humans who committed crimes or were enemies of the state in the hippodrome throughout the Byzantine Empire, as well as victory celebrations and imperial coronations.
The chariot races were important in the Byzantine Empire, as in the Roman Empire, as a way to reinforce social class and political power, including the might of the Byzantine emperor, and were often put on for political or religious reasons. In addition, chariot races were sometimes held in celebration of an emperor's birthday. An explicit parallel was drawn between the victorious charioteers and the victorious emperor. The factions addressed their victors by chanting "Rejoice...your Lords have conquered" while the charioteer took a victory lap, further indicating the parallel between the charioteer's victory and the emperor's victory. Indeed, reliefs of Porphyrius, the famous Byzantine charioteer, show him in a victor's pose being acclaimed by partisans, which is clearly modeled on the images on the base of Emperor Theodosius's obelisk. The races could also be used to symbolically make religious statements, such as when a charioteer, whose mother was named Mary, fell off his chariot and got back on and the crowd described it as "The son of Mary has fallen and risen again and is victorious."
The Hippodrome of Constantinople (really a Roman circus, not the open space that the original Greek hippodromes were) was connected to the emperor's palace and the Church of Hagia Sophia, allowing spectators to view the emperor as they had in Rome. Citizens used their proximity to the emperor in the circuses and theatres to express public opinion, like their dissatisfaction with the Emperor's arrant policy. It has been argued that the people became so powerful that the emperors had no choice but to grant them more legal rights. However, contrary to this traditional view, it appears, based on more recent historical research, that the Byzantine emperors treated the protests and petitions of their citizens in the circuses with greater contempt and were more dismissive of them than their Roman predecessors. Justinian I (r. 527–565), for instance, seems to have been dismissive of the Greens' petitions and to have never negotiated with them at all.
There is not much evidence that the chariot races were subject to bribes or other forms of cheating in the Roman Empire. In the Byzantine Empire, there seems to have been more cheating; Justinian I's reformed legal code prohibits drivers from placing curses on their opponents, but otherwise there does not seem to have been any mechanical tampering or bribery. Wearing the colours of one's team became an important aspect of Byzantine dress.
Chariot racing in the Byzantine Empire also included the Roman racing clubs, which continued to play a prominent role in these public exhibitions. By this time, the Blues (Vénetoi) and the Greens (Prásinoi) had come to overshadow the other two factions of the Whites (Leukoí) and Reds (Roúsioi), while still maintaining the paired alliances, although these were now fixed as Blue and White vs. Green and Red. These circus factions were no longer the private businesses they were during the Roman Empire. Instead, the races began to be given regular, public funding, putting them under imperial control. Running the chariot races at public expense was probably a cost-cutting and labor-reducing measure, making it easier to channel the proper funds into the racing organizations. The Emperor himself belonged to one of the four factions, and supported the interests of either the Blues or the Greens.
Adopting the color of their favorite charioteers was a way fans showed their loyalty to that particular racer or faction. Many of the young men in the fan clubs, or factions, adopted extravagant clothing and hairstyles, such as billowing sleeves, "Hunnic" hair-styles, and "Persian" facial hair. There is evidence that these young men were the faction members most prone to violence and extreme factional rivalry. Some scholars have tried to argue that the factional rivalry and violence was a result of opposing religious or political views, but more likely the young men simply identified strongly with their faction for group solidarity. The factional violence was probably engaged in similarly to the violence of modern football or soccer fans. The games themselves were the usual focus of the factional violence, even when it was taken to the streets. Although fans who went to the hippodrome cheered on their favorite charioteers, their loyalty appears to be to the color for which the charioteer drove more than for the individual driver. Charioteers could change faction allegiance and race for different colors during their careers, but the fans didn't change their allegiance to their color.
The Blues and the Greens were now more than simply sports teams. They gained influence in military, political, and theological matters, although the hypothesis that the Greens tended towards Monophysitism and the Blues represented Orthodoxy is disputed. It is now widely believed that neither of the factions had any consistent religious bias or allegiance, in spite of the fact that they operated in an environment fraught with religious controversy. According to some scholars, the Blue-Green rivalry contributed to the conditions that underlay the rise of Islam, while factional enmities were exploited by the Sassanid Empire in its conflicts with the Byzantines during the century preceding Islam's advent.
The Blue-Green rivalry often erupted into gang warfare, and street violence had been on the rise in the reign of Justin I (r. 518–527), who took measures to restore order, when the gangs murdered a citizen in the Hagia Sophia. Riots culminated in the Nika riots of 532 AD during the reign of Justinian, which began when the two main factions united and attempted unsuccessfully to overthrow the emperor.
Chariot racing seems to have declined in the course of the seventh century, with the losses the Empire suffered at the hands of the Arabs and the decline of the population and economy. The Blues and Greens, deprived of any political power, were relegated to a purely ceremonial role. After the Nika riots, the factions grew less violent as their importance in imperial ceremony increased. In particular, the iconoclast emperor Constantine V (r. 741–775) courted the factions for their support in his campaigns against the monks. They aided the emperor in executing his prisoners and by putting on shows in which monks and nuns held hands while the crowd hissed at them. Constantine V seems to have given the factions a political role in addition to their traditionally ceremonial role. The two factions continued their activity until the imperial court was moved to Blachernae during the 12th century.
The Hippodrome in Constantinople remained in use for races, games, and public ceremonies up to the sack of Constantinople by the Fourth Crusade in 1204. In the 12th century, Emperor Manuel I Komnenos (r. 1143–1180) even staged Western-style jousting matches in the Hippodrome. During the sack of 1204, the Crusaders looted the city and, among other things, removed the copper quadriga that stood above the carceres; it is now displayed at St. Mark's Cathedral in Venice. Thereafter, the Hippodrome was neglected, although still occasionally used for spectacles. A print of the Hippodrome from the fifteenth century shows a derelict site, a few walls still standing, and the spina, the central reservation, robbed of its splendor. Today, only the obelisks and the Serpent Column stand where for centuries the spectators gathered. In the West, the games had ended much sooner; by the end of the fourth century public entertainments in Italy had come to an end in all but a few towns. The last recorded chariot race in Rome itself took place in the Circus Maximus in 549 AD.
- A number of fragments of pottery from show two or more chariots, obviously in the middle of a race. According to Bennett, this is a clear indication that chariot racing existed as a sport from as early as the thirteenth century BC.
