1. Roman Budget 150 AD (1: Duncan-Jones, p.45) The above figures are estimates, and should not be construed
to imply a government deficit, as Understanding the above revenue and expense equation is key to understanding the financial ruin of the Empire over the course of several centuries. Military costs, including discharge costs, consumed over 70% of the government’s revenue once the number of legions reached 33 under Septimus Severus. Vespasian had already increased taxes about as far as they could go without causing unrest, so there was little room to increase funding during periods of extraordinary expenditure due to war or the reigns of extravagant emperors. Meanwhile, there was little room for reducing expenditure significantly, apart from reducing the size of the military. During Republican times, financial ruin was avoided during periods of financial stress by conquering and ravishing some new province. This was no longer possible, since virtually all of the available profitable territories had already been annexed. The barbarian tribes north of the Empire held no wealth worth taking. (Augustus said that further conquest would be like fishing with a golden hook.) Nevertheless, the Empire did have some financial expedients at its disposal when needed, which are discussed by Duncan-Jones and summarized below (1: Duncan-Jones, pp.5-10). 1. Property of the condemned (bona damnatorum). “A recurrent theme is the condemnation of the rich for treason or social dereliction.” (1: p.5) Over time this method of funding destroyed the old Senatorial class, which was replaced by a new landed elite that derived power from, and owed loyalty to, the Emperor. 2. Special Levies and payments. “The most recurrent of the other forms of
payment was aurum coronarium. Originally a perquisite of successful
generals under the Republic…it also celebrated the accession of a new Emperor,
soon becoming a regular event. Augustus
refused 35,000 pounds of aurum coronarium offered by
the towns of 3. Precious metal from temples and statues. “In the Severan
period, statues of Plautianus were melted down after
his fall in 205, and gold lions were melted under Elagabalus. Under Macrinus there
had been a general outcry for all gold and silver statues to be melted down,
from a citizen body whose taxes had just been increased.” (1: p.10) 4. Sales of goods. “The state’s use of sale mechanisms is shown in the sale of conquered populations as slaves…. Less predictable are the sales of palace goods which took place at times of fiscal stress. They are attested under Caligula, Nerva and Marcus Aurelius…. Pertinax sold off palace goods, slaves, carriages and arms belonging to Commodus, after inheriting a virtually empty treasury. Severus Alexander reputedly sold off the palace dwarves.” (1: p.10) We conclude, from the above data, that the Empire had very little flexibility in its budget, either on the revenue side or the expense side. So long as there were no significant external threats to the Empire, the budget was sustainable over the long haul. However, once the barbarian assaults became chronic and widespread, rather than local and sporadic, the Empire found itself in a slow, grinding, relentless decline. Victories over the barbarians could not yield financial gain, while defeats did yield financial loss – in property damage, disrupted trade, and a reduced tax base. The government responded with ever increasing tax rates that slowly choked off the whole economy, and eventually destroyed the state. Debasement, Price Inflation, and Military PayDebasement of bronze and silver coinage started in the reign of Nero. We provided a table showing debasement of the denarius to 235 AD in When Gold is King (p.4) at www.freebuck.com/articles/elliott/00whengoldisking.htm (showing weight and purity of the denarius). A similar table showing the number of denarii per pound of silver is on p.3 of The Roman Economy at www.personal.kent.edu/~bkharvey/roman/economy.htm.
Virtually every Emperor, starting with Nero, debased the coinage to some extent, but the impact was minimal through the middle of the second century AD. Under Augustus, the denarius had been 98% pure silver, and the purity declined only modestly, to 90%, by the time Hadrian died in 138. Antonius Pius (138-161) reduced purity of the denarius to 86.5%, Marcus Aurelius (161-180 AD) reduced purity to 78%, Commodus (180-192) reduced purity to 73%, Septimus Severus (193-211) reduced purity to 55.5%, and Caracalla (211-217) reduced purity to 51.5%. Silver debasement under Caracalla was greater than it appears from looking at the denarius, because he also introduced the Antinonianus (double denarius) with 50% more silver than the denarius, but valued at twice as much. Antinonianus production represented 50% of the face value of all silver coins produced after the Antinonianus was introduced (1: Duncan-Jones, p.142). Debasement of the currency by some percentage will
eventually cause price increases of the same percent (all else being equal) so
why do it? Under the Republic, Pliny
said that debasement represented partial debt default by the government, but
there was no debt under the Empire to default on. Keith Hopkins provides an answer, saying
that although the army rarely intervened in central politics, Emperors always
feared they might. “The army had to be
placated. What is surprising then is
that, given the army’s potential for disruption, soldiers’ pay in terms of silver
never surpassed the level which it reached in the reign of Augustus. Or put another way, every time that the
nominal pay of soldiers was subsequently raised the silver coinage was soon
debased, so that the cost in precious metal to the treasury was held roughly
constant.” (2:
Table 2: Roman Military Pay (1: Duncan-Jones, p. 34) We observe that Vespasian’s tax increase in the 70s AD (increasing revenues from HS670 million to HS804 million) gave his son Domitian the resources to increase soldier’s pay from HS900 to HS1200. The pay increase of Septimus Severus in 202 AD was followed by massive debasement (from 73% to 55.5% purity), and Caracalla’s pay increase was likewise followed by major debasement. This debasement had significant impact on general price levels, which Duncan-Jones calculates to have risen 177% from 100 AD to 220 AD (1: Duncan-Jones, p.28). The military pay increase from 100 AD (HS1200) to 220 AD (HS2400) was 100%. However, the pay increase from 83 AD (HS900) to 220 AD (HS2400) was 167%, very close to the general price inflation from 100 AD to 220 AD. This price inflation was not due to an increase in monetary gold and silver, as some might assume. Duncan-Jones estimates total Roman money supply in the middle of the second century at HS20,517 million (HS12,012 million in gold, HS6,864 million in silver and HS1,641 million in bronze coinage) (1: Duncan-Jones, p.170). Annual coin production, averaging HS200 million (1% of the money supply), merely offset a wastage rate of 1% per year (coinage wear & other losses), leaving the money supply roughly unchanged (1: Duncan-Jones: p.167 & p.205). Therefore, the price inflation to 220 AD was strictly due to debasement, which was done primarily to fund military pay increases. After Caracalla,
the rate of monetary debasement accelerated, reducing silver content of the
coinage to 40% by 250 AD and virtually to zero by 270 AD (coins were silver
washed bronze). This monetary collapse
caused hyperinflation, with estimates of general price increases ranging from
“at least a factor of 27” from second century prices to the 290s (3:
Duncan-Jones, p.115) to 15,000% in the third century (6: Bartlett, p
8). (Perhaps the
difference can be largely explained by the slight difference in time frames
being considered by Bartlett and Duncan-Jones.)
To control the hyperinflation, Diocletian passed an edict in 301 which
set maximum prices on some 800 items.
Wages were defined in the edict (section VII.1 to VII.76), with daily
unskilled wages (eg. farm labor, mule drivers, and
sewer cleaners) set at 25 denarii, and daily skilled
wages (eg. carpenters, masons, shipwrights, and
blacksmiths) set at 50-60 denarii (10: Frank, pp.
337-40).
These wage rates were fifty times the wage rates at the end of the
Republic. Meanwhile, legionary pay had doubled under Maximinus (235-238) and by the reign of Diocletian (284-305) pay was 1,800 denarii (HS7,200). This was supplemented by extra donations on special occasions (such as the Emperor’s birthday) and by in-kind pay in grain, bringing total compensation to an estimated 12,400 denarii (HS49,600) plus 30 modii (196.5 kg) of wheat (3: Duncan-Jones, p.116). This total compensation was 55 times the legionary wage rate at the end of the Republic. Diocletian’s edict did not halt the spiraling prices, in spite
of the threat of capital punishment.
Diocletian specified that a pound of gold was worth 50,000 denarii, but the market rate deteriorated to 100,000 denarii/pound of gold by 307 AD, 300,000 denarii/pound of gold by 324 AD, and an incredible 2.1 billion
denarii/pound of gold by the middle of the fourth
century (7:
Davies, pp.3-4). “Diocletian’s
other reforms, however, were more successful.
The cornerstone of Diocletian’s economic policy was to turn the ad hoc
policy of requisitions to obtain resources for the state into a regular
system. Since money was worthless, the
new system was based on collecting taxes in the form of actual goods and
services, but regularized into a budget so that the state
know exactly what it needed and the taxpayers knew exactly how much they
had to pay.” (6: Revenue Losses and Non-military Expenditures Due to the Barbarian InvasionsWe provided a summary of the barbarian assaults in Rise and Fall of Civilizations Part II (p.8) at www.freebuck.com/articles/elliott/00riseandfall2.htm. Widespread barbarian invasions began in the middle of the third century, and the tempo of assault increased with the appearance of the Huns in 376. These assaults caused the Empire numerous financial drains, in addition to the direct military costs already discussed. Aurelian spent several years
(271-276) rebuilding the walls of This looting and physical damage to Roman property reduced
taxes derived from provinces that were recovered after barbarians overran
them. For example, “in 445 AD state
revenue was 9,600 solidi for Meanwhile, In additional to all of these financial impacts, after the Battle of Adrianople in 378, the Empire also began bribing barbarian tribes not to raid the Empire. Growing Welfare and Bureaucracy CostsThe HS44 million budget for cash handouts in 150 AD (Table 1) was composed of HS22 million in public handouts (congiaria) typically paid to citizens in gold aurii, and an equal figure for cash donatives to the military. By 212 AD the cost of cash handouts had grown dramatically to HS140 million (HS70 million in congiaria and HS70 million in military donatives) (1: Duncan-Jones, pp.40-41 & p.249). By 300 AD the military donatives had grown to the point where they constituted the bulk of legionary remuneration, as we already discussed. We do not have figures for congiaria in the last centuries of the Empire. The cost of civilian employees in 150 AD was HS75 million. The pay of 35 provincial governors, earning HS500,000 to HS1 million each, was the largest single component, costing HS24.5 million, or one
third of the total. By 212 AD civilian
pay was unchanged at HS75
million (1:
Duncan-Jones, pp.37-39). Numerous
sources attest to a growing and bloated state bureaucracy in the final
centuries of the Empire, but we have no figures to quantify the cost. Gibbon provides anecdotal evidence at the
beginning of the reign of Julian (361-363) that describes the situation: “Soon after (Julian’s) entrance into the Collapse of the Empire: 337 to 476
A description of historical events subsequent to 337 AD can be found at: www.roman-empire.net/collapse/collapse-index.html. The shrinking revenue and increased spending from all the
above causes led the state to increase taxes wherever it could, doubling tax rates during the middle of the fourth
century. “Small landowners, crushed into
bankruptcy by the heavy burden of taxation, threw themselves on the mercy of
large landowners, signing on as tenants or even slaves. The latter phenomenon was so widespread and
so injurious to state revenues, in fact, that in 368 AD Emperor Valens declared it illegal to renounce one’s liberty.” (6: Fourth century legions deteriorated to the point where they
were composed of only tenant farmers and barbarian mercenaries. Diocletian had increased the number of
legions to 60, but these legions, at the end of the fourth century, existed
only on paper and were never up to strength.
By 406 the situation was so desperate that Honorius
enlisted slaves in the army. In the
Battle of Chalons in 451, one of the greatest
strategic battles of Roman history, the Roman army was composed almost entirely
of barbarians, with virtually no Romans present at all. Aurelio Bernardi
says: “The negative consequences of the shrinking fiscal revenue on the
efficiency of the army existed also in regard to other fundamental services of
the state – provisioning of the great cities, gratuitous distributions to the
urban plebs, transportation, maintenance of roads, public games, etc.” (5: Bernardi, p.76) As for the private sector, banking was abandoned in We provided extensive commentary on the fall of the www.freebuck.com/articles/elliott/00riseandfall3.htm The Dark AgesThe savvy reader with a knowledge
of history realizes that the fall of Note on Wheat PricesDuncan-Jones says the price of wheat in the early Empire was about HS4 per modius (11: Duncan-Jones, p.42). In calculating the value of the dole based on HS9 per modius, Hopkins says the price of wheat in the city of Rome was 4 times higher than in Egypt, and 2-3 times higher than in Sicily and the rest of Italy (2: Hopkins, p.8). Diocletian’s price edict (section I.1) in 301 AD set the maximum price of wheat at 100 denarii (HS400) (10: Frank, p.318). Sources1. Duncan-Jones, Richard. Money and
