tetrarchy

A form of federal government in which power is divided between four individuals. In ancient Rome, a mechanism of government instituted through Diocletian that separation power in between two rulers in the east, and two rulers in the west.

Diocletian

Roman emperor native 284 come 305 CE. Created the tetrarchy and also instituted economic and also tax revolutionary to stabilize the roman inn Empire.


Diocletian and the Stabilization that the roman Empire

Diocletian was roman inn emperor indigenous 284 come 305 CE. Born come a family of low status in the Roman district of Dalmatia, Diocletian rose through the ranking of the army to come to be cavalry commander to the Emperor Carus. ~ the deaths of Carus and also his kid Numerian on project in Persia, Diocletian to be proclaimed emperor. Diocletian’s power stabilized the empire, and significant the end of the crisis of the 3rd Century. The appointed other officer, Maximian, together Augustus, co-emperor, in 286. Diocletian delegated further in 293, appointing Galerius and also Constantius as caesars, junior co-emperors. Under this “tetrarchy,” or “rule the four,” each emperor would preeminence over a quarter-division that the empire. Diocletian additional secured the empire’s borders and also purged the of all threats to his power.

He separated and also enlarged the empire’s civil and military services and reorganized the empire’s provincial divisions, creating the largest and also most administrative government in the background of the empire. The established new administrative centers in Nicomedia, Mediolanum, Antioch, and also Trier, closer come the empire’s frontiers than the traditional resources at Rome had actually been. Building on third-century trends towards absolutism, that styled self an autocrat, elevating himself above the empire’s masses with imposing creates of court ceremonies and also architecture. Bureaucratic and military growth, constant campaigning, and construction projects increased the state’s expenditures and also necessitated a comprehensive tax reform. Indigenous at least 297 on, imperial taxation was standardized, made much more equitable, and levied in ~ generally greater rates.

The Tetrarchy

The first phase of Diocletian’s federal government restructuring, periodically referred to as the diarchy (“rule that two”), affiliated the designation that the basic Maximian as co-emperor—first together Caesar (junior emperor) in 285, climate Augustus in 286. This reorganization permitted Diocletian come take care of problem in the eastern areas of the empire, when Maximian similarly took fee of the west regions, thereby halving the bureaucratic work compelled to oversee realm as big as Rome’s. In 293, feeling more focus was needed on both civic and also military problems, Diocletian, with Maximian’s consent, expanded the royal college through appointing 2 Caesars (one responsible to each Augustus)—Galerius and Constantius Chlorus.

In 305, the an elderly emperors together abdicated and also retired, permitting Constantius and Galerius to be elevated in location to Augusti. They subsequently appointed two brand-new Caesars—Severus II in the west under Constantius, and Maximinus in the eastern under Galerius—thereby developing the second tetrarchy.

The 4 tetrarchs based themselves no at Rome yet in other cities closer come the frontiers, mainly intended together headquarters for the defense of the empire against bordering rivals. Although Rome ceased to it is in an operational capital, it continued to it is in the nominal funding of the entire Roman Empire, not lessened to the status of a province, but under that is own, unique Prefect the the City (praefectus urbis).

In terms of regional jurisdiction, there to be no precise division between the four tetrarchs, and also this period did not view the roman inn state actually break-up up into four distinctive sub-empires. Every emperor had his region of influence within the roman Empire, yet this influence mainly used to the theatre of war. The tetrarch to be himself frequently in the field, when delegating many of the management to the hierarchic bureaucracy headed by his respective Praetorian Prefect. The Praetorian Prefect to be the title of a high office in the roman Empire, originating as the commander of the Praetorian Guard, the office slowly acquired considerable legal and administrative functions, v its holders becoming the emperor’s chef aides.

Demise that the Tetrarchy

When, in 305, the 20-year hatchet of Diocletian and also Maximian ended, both abdicated. Their Caesares, Galerius and Constantius Chlorus, to be both elevated to the rank of Augustus, and also two brand-new Caesares were appointed: Maximinus (Caesar come Galerius) and also Flavius Valerius Severus (Caesar to Constantius). These four formed the second tetrarchy.

However, the system damaged down really quickly thereafter. Once Constantius died in 306, Galerius advocated Severus to Augustus while Constantine, Constantius’ son, was proclaimed Augustus through his father’s troops. At the very same time, Maxentius, the boy of Maximian, who additionally resented gift left out of the new arrangements, beat Severus prior to forcing him come abdicate and also then arranging his murder in 307. Maxentius and Maximian both then asserted themselves Augusti. By 308, there were therefore no under than 4 claimants come the location of Augustus (Galerius, Constantine, Maximian and also Maxentius), and also only one to that of Caesar (Maximinus).

In 308, Galerius, in addition to the retirement emperor Diocletian and the supposedly retirement Maximian, called an imperial “conference” in ~ Carnuntum on the river Danube. The board of directors agreed that Licinius would become Augustus in the West, v Constantine together his Caesar. In the East, Galerius stayed Augustus, and also Maximinus continued to be his Caesar. Maximian to be to retire, and Maxentius was declared an usurper. This agreement proved disastrous: by 308 Maxentius had become de facto ruler of Italy and Africa also without any type of imperial rank, and neither Constantine nor Maximinus—who had actually both to be Caesares since 306 and also 305, respectively—were all set to pardon the promotion of the Augustus Licinius as their superior.

After an abortive effort to placate both Constantine and also Maximinus through the meaningless title filius Augusti (“son of the Augustus,” basically an alternative title for Caesar), they both had to be well-known as Augusti in 309. However, 4 full Augusti all at odds v each other did no bode well because that the tetrarchic system.

Between 309 and 313, most of the claimants come the imperial office died or were eliminated in various civil wars. Constantine forced Maximian’s self-destruction in 310. Galerius passed away naturally in 311. Maxentius was beat by Constantine in ~ the fight of the Milvian leg in 312, and also subsequently killed. Maximinus committed suicide at Tarsus in 313, ~ being defeated in fight by Licinius.

By 313, therefore, over there remained only two emperors: Constantine in the west and also Licinius in the east. The tetrarchic mechanism was at an end, although the took until 324 because that Constantine to lastly defeat Licinius, reunite the 2 halves of the roman inn Empire, and declare himself sole Augustus.
