THE FIRST TEST Rome could easily defend its borders if attacks came from one direction at a time

From either the Germans or the Parthians But it attacks occurred simultaneously, Rome was trouble

Roman policy had always made sure that this would not happen Parthian Empire kept weak by Roman encouragement of corruption and well-

time pre-emptive attacks But in 226 AD, the Parthian monarchy was overthrown by the Sassanians and

suddenly Rome was faced with a vigorous and aggressive enemy of its eastern frontier

GERMANS Along the German frontier,

Roman policy aimed at keeping the various tribes on the other side continually fighting among themselves so they would never be able to unite and threaten the border Movement of new tribes

into central Europe around 200 AD forced more established ones to unite into nations and push hard on the Roman frontier

Ostrogoths, Visigoths, Franks, Alamanni

BORDER DEFENSES

Problems made worse by the fact that legion were concentrated only on the frontier and units were fairly isolated from each other Therefore when barbarians

did break through border defenses, there were no troops further inside the empire to check their progress

German tribes broke through Rhine defenses four times between 254-280 AD and advanced as far as Spain and North Africa before they were finally stopped

Ostrogoths broke through Danube defenses and plundered Greece

ROMAN RESPONSE

Romans strengthened their defenses Towns and cities now surrounded by fortified walls Forts constructed away from border Cavalry units enlarged and consolidated into mobile legions to

quickly catch and defeat tribes who had broken through border defense

In short, Rome divided army into internal, mobile forces and static frontier garrisons

All this was a good idea but very expensive

CUTTING PARTS

Rome let go of some of its hardest to defend territories In order to concentrate its military

strength on more important areas Let go of part of Rhine frontier,

Dacia, and Mesopotamia Borders restabilized by 384 AD

Army morale was lower, occasional mutinies and desertions were more frequent and an increasing number of soldiers were of German barbarian origin

But the army still held the advantage against the barbarians

ROMAN GOVERNMENT Roman government had become a mess

Fragile system of imperial succession established by Augustus had completely broken down

The basis reason is that the successors to Septimius Severus were so incompetent and inadequate that they managed to totally destroy the image of imperial rule that had been so painstakingly built up over the previous 200 years

Result was ambitious generals and chiefs of the Praetorian Guard felt freer to gamble and seize power

Pressure on the frontier also played a role

SOCIAL AND ECONOMIC RESULTS OF TURMOIL

Steady decline in population Due to invasions, civil war, and

plague Decrease in manufacturing and

agricultural production Severe drop-off in trade Overall rise in pessimism and gloom

in provinces But at the same time the

demands of the state on the resources of the provinces increased

In short, the economic and manpower base of the empire was shrinking but the demands on that base were expanding Result was impoverishment of

the people of the empire

SOCIAL TRANSFORMATION

City residents were easiest to squeeze with increased and new taxes People left cities as a result

Wealthy bought villas out in countryside to be safe from tax collectors

Smaller landowners turned to larger ones for protection and aid from tax collectors

In exchange for this they gave up their land to the large landowners

SUMMARY A process of massive transformation began in the

provinces of the Roman Empire The result of pressure from the state, declining

production and population, and the general insecurity caused by civil war and barbarian invasion

Cities shrank to shadows of their former selves Mainly populated by criminals and people too poor to

get away Both groups kept in line by harsh laws, harsher

punishments, and huge garrisons of soldiers The countryside, at the same time, was developing into a

pattern of isolated, self-sufficient, and semi-independent units in which tenants, sharecroppers, and peasants tied themselves to a powerful local landowner and his villa

DIOCLETIAN AND CONSTANTINE

PRAGMATIST

40 year old pragmatist who would halt the chaos of previous decades and buttress the empire with a series of reforms that gave it a new lease on life Consolidated the trend towards authoritarianism that had

begun in the days of the Antonines and placed all elements of society in a state of continual mobilization

Also added elements of his own personality Humble origins, the son of a freedman Immense practicality Risen in the army through his own merits and

worshipped order and efficiency Realism was diluted by military background

Believed in government by decree and assumed orders would always be obeyed without question

TETRARCHY

Used precedent from Marcus Aurelius to create Tetrarchy Two co-emperors (each with title of

Augustus) Each had an assistant and

designated heir (with title of Caesar)

Diocletian was one of the co-emperors But he also retained the position of

“chairman of the board” within this system

After 20 years, both Diocletian and his co-emperor retired and elevated their Caesars to their former positions Hoped that this new system would

provide for an orderly succession in the future and free the empire from the recurring nightmare of civil war

PROTOCOL AND PAGEANTRY

Protected himself behind an host of secretaries and courtiers Size of imperial court

rapidly expanded Also portrayed himself as

the earthly representation of a god Often portrayed with a

halo Wore gorgeous

costumes Golden crown,

robes of golden cloth, jewel-studded shoes

Turned position of emperor into a remote, semi-divine figure, protected by a wall of protocol and pageantry

PROBLEMS AT THE PALACE

Successors would become distracted by the pomp of the court Also isolated by the court

Strong rulers dominated their courtiers but weak ones became the puppets of their own servants

Emperor and family served by eunuchs From Armenia or Persia Had more access to ruler than

senators or generals Dependent solely on the emperor

No past or future, no local ties, and no family

Still notorious for the greed and continually involved in plots

Deprived of normal pleasures, they sought money and power

CONSERVATIVE MOTIVATIONS

Creation of Tetrarchy was in large part a response to military crisis When Diocletian became

emperor, Gaul was being ravaged by Franks and Alemanni and peasants were in revolt

Diocletian’s friend Maximian restored order

Diocletian made him co-emperor as a reward

Positions of Caesar were created to deal with other military threats

Young general named Galerius became Diocletian’s Caesar and Constantius became Maximian’s Caesar

Diocletian and Maximian

Diocletian resided in Nicomedia and

guarded eastern border

Galerius guarded the Danube River from a fortress in

the Balkans

Maximian made Milan

his headquarters

Constantius centered his

operations in Trier in Gaul

None of them made Rome their

headquarters

MOVE TOWARDS ABSOLUTISM

Diocletian erected a pyramid of absolutism and oppression in piecemeal fashion Required his people to

support a never-ending military effort, an expanding bureaucracy, and four imperial courts

Relied mostly on equestrians for government officials Because of their

experience and their gratitude for advancement

Created 100 new mini-provinces,

governed by equestrians, and grouped into 12 large

administrative districts known

as dioceses

Chief administrator for each diocese were called vicars and were drawn from the

equestrian class

Separated civilian and

military authority in the frontier provinces

where most of the army was

stationed

Despite his best efforts, the system still swarmed

with parasites and required a network of

spies and secret police

BIG ARMY/HIGH TAXES Local officials required to

furnish a certain number of recruits to the army each year or else pay money to hire soldiers in their place

Diocletian decreased size of legions but increased their number Army probably numbered

500,000 men To pay for all this,

Diocletian stabilized currency and reformed the tax structure

Many taxes now paid in kind

Cash head tax on farm laborers and tenant farmers

UNFAIR SITUATION Heavy taxes provoked

tenants to abandon farms and run away When a community

could not meet its projected tax obligations because of this, local officials had to make up the difference out of their own pockets

They were also responsible for putting down rural discontent and capturing runaway tenants

Great landowners managed to avoid paying their fair share of taxes by bribing state officials and secret agents

INFLATION Rampant inflation had been a serious problem for the 50 years

before the advent of Diocletian Prompted by war and swollen government expenditure

Diocletian’s monetary reforms prompted speculation in coins among his officials Who knew in advance that their value would change

To get a handle on the situation Diocletian specified maximum prices, wages, and freight charges Ordered death penalty for violators Motivation was to stop inflation and protect his subjects from

overcharging profiteers But edict was indifferently enforced and greedy merchants

risked death penalty to hoard products and sell them for high prices on black market

Edict was no longer in effect by the time of Constantine

PERSECUTION OF CHRISTIANS

Diocletian ordered that all palace officials worship the state gods of Rome in 299 AD Galerius pushed to extend order

to the army and to purge Christian officers

Produced oracle who predicted destruction of the empire unless this was done

Diocletian bans Christian rites and confiscating books and churches

Two fires broke out in palace and Galerius convinced Diocletian that Christians had started them Diocletian then launches full-

scale attack on Christians

CHANGING OF THE GUARD

Diocletian visits Rome in 304 and orders baths to be built to commemorate visit. Now 60 years old and seriously

ill Galerius convinces him to

retire later that same year Maximian retired at the same

time New Augusti, Galerius and

Constantius, appoint new Caesars

Galerius: nephew Maxentius Daia

Constantius: drinking buddy Serverus

Diocletian retires to his villa and spends his last days gardening

RISE OF CONSTANTINE

New power struggles erupted between new Tetrarchs

Ultimately resulted in all their deaths and the victory of Constantine

Son of Contantius Born in Balkans and

poorly educate Won final battle at

Mulvian Bridge Between him and

Maxentius Daia Had vision the night

before the battle that he would win if his soldiers had Greek symbol of Christ on their shields

Later elaborated and exaggerated the dream

POWER After victory, Constantine entered Rome,

disbanded Praetorian Guard, and left Never to return again

Repaid debt to Christian god by endorsing a policy of toleration Became patron and protector of

Christians Originally had a co-emperor and both had a

Caesar But he ultimately eliminated them all Was sole Augustus by 324 AD and

named his two sons as his Caesars Believed in dynastic succession

DEVELOPMENTS Constantine favored senators over equestrians and placed members of

the aristocracy in high positions Roman society became stratified along class lines

Began to resemble caste system Many occupations deemed necessary to national defense

were made hereditary Municipal officials known as decurions were locked into

their jobs Tenant farmers were reduced to virtual serfdom

Prohibited from leaving their land and completely under the control of local landlords

Senatorial class avoided its obligations through bribery Corruption of judges and administrators remained a big

problem Created elite mobile military force made up of cavalry and mercenary

specialists Issued stable gold coinage but most taxes still collected in kind

CONSTANTINOPLE Converted old city of Byzantium into

a “New Rome” New capital renamed

Constantinople Not far from Diocletian’s old

headquarters in Nicomedia Reflected shift of

empire’s center of gravity to the east

Filled with massive public buildings

Immigrants lured to new city with cash gifts and promises of free food and public entertainment

FIRST CHRISTIAN EMPEROR? Did not want to anger pagan majority and

thus went through motions of supporting pagan rites But support for Christianity became

official policy in 312 Mulvian Bridge emblem put on

all his banners and crucifixion abolished

Not interested in theology but impressed by organizational strength of the Church

Became more religious as he became older Built a number of churches and

increased the influence of bishops at his court

But postponed baptism until he was on his deathbed

SAINT OR SINNER? Lauded by Christian apologists and

detested by pagans, Constantine’s reputation has not been high among modern skeptics

He was a worldly, blood-splattered emperor who was impatient with the fine points of theology But he was in awe of Christian magic

and willing to turn his back on 1000 years of pagan tradition

He was a revolutionary in a religious sense and put the Roman state under the protection of a new god and into the hands of a new religious sect

REVITALIZATION As reconstituted by Diocletian and

Constantine, the empire survived its first test and enjoyed new burst of prosperity, stability, and intellectual vitality Witnessed by amazing construction

boom Constantinople grew virtually

overnight from nothing to a huge, beautiful metropolis

In the West, Trier, Milan, Ravenna, and Rome experienced major facelifts and expansion

Capital in West moved from Rome to Milan and then to Ravenna for defensive purposes

But Christian bishops in Rome built huge basilicas
