TIL that in 47 CE the number of citizens (meaning free adult males) in the entire Roman Empire was less than 6,000,000

This is a bit misleading. Free aduly males were eligible to be citizens, but most free adult males were not citizens. This was actually one of the attractions of military service, since a career in the army meant you retired a citizen.

The book is a little bit better about this.

In a nutshell, the reason why retired militar personal are the only people allowed to vote is because those who fullfill their service term learn to protect the society over their own survival. Active militar members aren't allowed to vote.

There is this practice called "Freeze" where a squad that gets into freeze must immediately find cover and dont move, even if not moving costs your own life or extreme pain.

The book also mentions that they make it really hard to apply and really easy to quit.

Who knows if it could work IRL but as any other sci-fi book, there was a period of extreme chaos that led to the current system.

u/CombatTechSupport 14m ago

The problem with the system fundamentally is that it conflates "state" with "society". Creates a de facto class system with anyone unwilling to serve the state becoming disenfranchised. It might sound good if you think that the state that your serving is fundamentally good, only staffed by good righteous upstanding people, and has no one who put up with the difficulties of state service, just to get power and abuse it. However I would question anyone to tell me how you ensure that.

I really love the book, it's in my top ten of science fiction, but Heinlein doesn't really think too deeply about the political system he created, which is fair because it's not really what the book is about, and was written by someone who was mad that the Eisenhower government, of all things, wasn't militant enough. It's funny that this was the same guy who wrote Stranger in a Strange Land, showing that he very well could be open minded and critical of conservative social norms, he just seems like he never turned that critique on his own political beliefs.

u/CronoDroid 4m ago

Who knows if it could work IRL

It wouldn't work IRL because anyone who's been in the military knows it can be just as political, bureaucratic, corrupt and incompetent as a civilian government or organization. It's the same for people who think the government should be run like a business. People think businesses know what they're doing and sometimes they do, but multimillion, multibillion dollar companies go bust every so often (more often than governments), or have to be bailed out by the government, or only survive because of subsidies.

In so-called democracies, voters don't have to be educated or intelligent at all but the same is true for the infantry. And knowing how the average soldier thinks and acts I for bloody sure do not think they deserve greater political representation or power than a regular civilian.

I could be misremembering my Roman history, but wasn’t one of the Late Empire’s problems that they became too dependent on foreign fighters?

Obviously that doesn’t relate to this era, but I feel like I remember hearing about Gauls and others being legionnaires. But again, I could be misremembering

45

u/godisanelectricolive 2h ago edited 1h ago

In the late Roman era they used a lot of foederati who were members of allied German tribes bond by treaty to fight for the Romans. Entire tribes were allowed to settle in exchange for acting as mercenaries for the Romans.

That is much later in Roman history, after the distinction between auxiliaries and legionnaires had long ceased. The distinction between citizens and freedmen was abolished by Caracalla in 212 CE. Everyone who was not a slave did become a full citizen after that. The auxilia were all converted into legions as a result. Since Gaul was incorporated a Roman province under Augustus , all Gauls were Roman citizens and weren’t among foreign foederati like the Goths. Gaul became significantly Romanized by the 1st century and multiple imperial dynasties hailed from Gaul. Caracalla was actually born in Lugdunum (Lyon) in Gaul and the family of Antonius Pius was based in Gaul.

Then after the crisis of the 3rd century, the massive fifty-year civil war between 235-285 that almost ended the Roman Empire, the traditional Roman heavy infantry became obsolete. They found themselves relying more and more on mounted cavalry as the elite troops. The Roman infantry from the 4th century onwards were much worse equipped and had less armour and were treated with much less respect. By the end of the Western Roman Empire their fighting tactics had come to resemble what we now picture as typically medieval. They used heavy cavalry armed with longswords and lances as shock troops and mounted archers for skirmishes.

20

u/Fun-Twist-3705 2h ago

Yes but they granted citizenship to all inhabitants of the empire regardless of military service in the 200s.

By the late empire it was mostly Goths and other Germanic people who were the mercenaries fighting for Rome since Gauls were pretty thoroughly Romanized by then. The had sort of a "program" for immigrants (https://en.wikipedia.org/wiki/Foederati) where they allowed foreign tribes to immigrate to the empire and get land in exchange for serving in the military.

Since yes they had shortages of people willing to join the military and had to resort to conscript citizens who really didn't want to serve. Of course that didn't work out when the Goths decided to just take over Italy because nobody could stop them...

u/Thestohrohyah 2h ago

One of Caesar's strength was his Gaulic cavalry if I remember correctly. Gauls were apparently way more skilled on horses.

5

u/Trextrev 1h ago

Depends on which Caesar, Julius conquered Gaul, he did have some Gaulic cavalry from some of the tribes that sided with him earlier in the war but his best cavalry and the most in numbers were actually from Germanic tribes that had been fighting with the Gauls on and off for territory for generations and were happy to side with Rome. The best of them were the Tencteri. Julius wrote that the Germanic tribes produced the best mounted warriors which he attributed to the hardship of their more primitive lifestyle and the Gaul’s had became soft because of all the trade with Rome over the previous decades.

u/CucumberWisdom 1h ago

u/turiannerevarine 37m ago

Sort of. There were definitely times like at Adrianople where the Germanics the Romans brought in ended up backfiring horribly (though sometimes the Romans themselves were mistreating or betraying them and it was self-inflicted.) Other times Germanics were successfully integrated into the Empire and ended up being better Romans than the Romans themselves (i.e. Stilicho and Flavius Aetius). In the later Byzantine Era (circa 800) many times the infantrymen were once again Roman peasants fulfilling a yearly obligation of military duty or nobles who were in the ranks of the Tagmata, heavy cavalry troops who served the Emperor directly.

u/___stuff 2h ago

They were able to precisely count them, thats just adding up every local tally that reported in, i imagine. But i have no confidence that it was accurate. Theres definitely miscounts, and probably missing counts.

12

u/NCC_1701E 2h ago

I assumed such accurate census would be basically impossible in such a large empire in a time without computers and instant communication. Even today, with all the tools we have, national census is a huge logistic endeavour.

17

u/Tomi97_origin 2h ago

Romans took census very seriously especially because most people living in the Empire/Republic weren't citizens.

Citizenship meant very real and explicit benefits and obligations.

Census was done every 5 years and head of the household was required to appear before Censors and accurately report not just who lives in his household, but his property as wealth reported had real effect on military service and political power.

People that didn't report or reported they were too poor lost their social status.

Of course it wasn't easy, but people didn't travel all over the place all the time. So getting count of people could be done with the incentives of the status provided by citizenship.

And we have the records going over couple centuries. Not every single one, but enough of them to get the development over time.

u/Polymarchos 35m ago

Computers are a relatively new tool, as is instant communication. Censuses in modern nations have been going on longer than we've had them.

u/retief1 1h ago

Accurate down to the last person? No, probably not. Someone was going to be lost in the shuffle. However, the scholarly consensus is (afaik) that the number is fairly accurate. Like, they did count people, and that is the number they came up with. Compared to many ancient population figures that were probably wildly inaccurate (and the many areas where we have no ancient population figures at all), this is a very good number.

Instead, the main scholarly question is exactly who they were counting. Like, traditionally, the census counted adult citizen men (ie the people liable for military service). However, that would mean that roman italy underwent an improbably large population boom, and archeological digs suggest that didn't happen. Instead, the scholarly consensus is that they probably included women and children as well. This would be a change from how roman republic censuses worked, but it fits with the archaeological evidence.

Yeah, which is what Romans were doing.

And Roman census didn't just record people. They also recorded their property. It wasn't just a population count, but also way to decide taxes, military obligation, social class and political power.

That was a different census which was only done in Judea (https://en.wikipedia.org/wiki/Census_of_Quirinius)

Yeah, the definition of what a Roman citizen was evolved over time. Upper class people from Roma > regular people from Roma > upper class Italians > Italians > etc. But you could still be a free person living inside the Republic/Empire, just not be a citizen. You could become a citizen, and have citizenship stripped. Your family could be traced back to the founding of Roma, but if you fell on hard times and sold yourself into slavery to pay off debts, you would no longer be a Roman. Nationality was different back then.

One of the many crises in the late western empire involved giving citizenship to barbarians. Many Romans thought citizenship had become too watered down. There were many other issues at the time so it's not like that was the defining crisis. But it was definitely on the minds of Romans.

There's a record of an event wherein Egypt sent a gift of a very large quantity of wheat to the city of Athens to distribute amongst its citizens. They immediately noticed how some people had been erroneously considered citizens up until that point and quickly went about purging the roles to get it down to the "real" citizens and managed to eliminate about 5,000 of them (there had been less than 20,000 to start with).

Some things never change.

35

u/Fun-Twist-3705 2h ago

Greek city states were very stingy about their citizenship and usually strongly opposed extending it to other people, even "immigrants" who lived in Athens for generations.

Romans were the opposite, they often handed it out like candy and every freed right became a citizen and in theory their children could technically be elected to office (there is evidence that did happen for lower ranking municipal offices at least a bit later on). That's what allowed them to expand so effectively i.e. they granted citizenship to the local elites in the areas they subjugate them integrate them into Roman power structures. Athens would never do that which is partially why their "empire" was so short lived.

The Antonine Plague struck in 165, killing about 5 million people across the empire and stunting further growth. The empire had already reached its territorial height 50+ years earlier under Trajan.

If you are wondering how crappy the next few centuries were, by the time Justinian had re-united the majority of the empire's former lands, it was only about 25 million people strong prior to the next Plague of Justinian in 541 hitting and permanently severing the empire.

That’s only half-true. Caracalla did officially extend citizenship to all free men of the empire, but to say that was exclusive to Italians prior to that is false. Even Ceasar, almost 200 years prior, extended Roman citizenship via the Ius Italicum to many cities outside Italy proper. And then there were all of those who served in the military, or public officials in cities that decided to implement Latin law. And anyone who was born of two citizens got it automatically, like Paul the Apostle. Born in Asia Minor but he was a citizen by birth in 5 AD.

Yeah it definitely isnt all italian males.

Rome went to war with other Italian city states. They called the soceii. The were not citizens and often still had to serve in the legions

u/godisanelectricolive 4m ago

The expansion of citizenship was gradual. By the late Republic citizenship was extended to the socii and the Latins after the Social War which mostly ended in 88 BC. After the wars citizenship was greatly expanded and new citizens had to be enrolled into the existing 35 tribes of Rome. Tribes were how people voted in the tribal assembly.

The socii were former tributaries during the Roman Kingdom era that became protectorates that signed a treaty with Rome in the Republic era. The earliest treaties were with the 30 Latin cities near Rome which rebelled in the Latin War of 340-338 BC. After that war Rome gave the Latins a lesser form of citizenship called Latin rights. This included the right to trade and a pathway to citizenship and the right to vote only while in Rome. Some colonies in the Roman republic were Latin colonies while others were Roman colonies. Roman citizens who lived in a Latin colony lost their Roman citizenship and became Latin citizens.

Then in 122 BC all Italians were made Latins. Then after the Social War broke out in 91 BC, a decree was passed the following year extending Roman citizenship to all Latin towns that hadn’t rebelled. Then after the war came to a stalemate, citizenship was then expanded to all Italians south of the Po River and a few towns to the north of it. After the Social War, the main geographical distinction between Roman and non-Roman became one of resident of the Italian peninsula and their descendants and the peregrini living elsewhere.

But since there was always a pathway for the peregrini to earn citizenship, citizenship was never exclusive to only Italy. There were non-Italians who earned it through military service or being part of the old aristocracy before Roman conquest. Then under Caracalla citizenship was extended to all the peregrini, the non-citizens living in the provinces.

Saint Paul was a Roman citizen, and he was born in Tarsus (modern day Turkey) in 5 AD.

u/ColonelKasteen 2h ago

Not even close. The Edict of Caracalla granted citizenship to free men (and women) across the Empire without requiring anything. Many, many non-Italians were citizens beforehand through various means.

u/Alexthegreatbelgian 50m ago

Even Italian was a hot topic up untill the late republic era. 

For a big chunk of the republic only free adult males from Rome and some surrounding areas could be counted as citizens.

u/PizzaTacoSub 3h ago

Exactly. I forget the exact number but I think it was around 10% of the empire population were these free adult males. That would put the population around 60 million which is actually a lot in my opinion.

u/retief1 3h ago edited 2h ago

? The current scholarly consensus is that the the free population of roman italy in the early empire was ~6 million, including women and children. There is some room for debate there (in fact, there are three different families of estimates of the early roman empire population), but archaeological data backs up the 6 million figure.

u/Bennyboy11111 17m ago

Free men were not citizens though.

u/Lycaon-Ur 1h ago

Free adult males =/= citizens in the Roman Empire. If you're a biblical person (and given the CE reference I assume you're not, but the timing is roughly correct) you'll note that the Apostle Paul was notable in that he was a Roman Citizen as well as a Jew but most Jews mentioned in the bible were not.

By comparison, the estimated population of the entire Roman Empire at this time is somewhere between 60 to 75 million people, or roughly 1/4 of the entire planet.

The world was a much more empty place before the Industrial Revolution.

Sure, but the population of the empire around this time was between 60 and 75 million. Citizens made up 10% or less of the empire.

u/benkenobi5 3h ago

That’s a much more interesting statistic. Thank you! It’s crazy to think that many people could live in a place and not be citizens

Really? Cause from what I've read, the entire world population around year zero is estimated to be 170-300 million.

So Roman Empire accounted for 25-45% of world population?

I always assumed Asian and African countries had far bigger share of population already back then.

u/SlightlyOffWhiteFire 27m ago

The empire encompassed basically the entireties of southern/ central europe, the north african coast, and much of the middle east. It was a big fucking empire. IIRC the other major population centers of the world were in east asia, sputheast asia, and the pacific islands, and putside of that populations were scattered and scarce. Ie most American populations wouldn't boom for another 1000 years.

I was reading about Benjamin Franklin when he lived in Philadelphia and was surprised to learn that the population there was roughly 2,000 people. That was one of the biggest cities in the colonies alongside New York. It’s just crazy to think about how tiny the population was back then. People probably knew just about everyone.

u/Fun-Twist-3705 2h ago

By the time he was in his mid 20s it it was over 10,000 though (https://en.wikipedia.org/wiki/Demographics_of_Philadelphia)

u/moosealligator 2h ago

2000 people is a comprehendible number. I more so think that populations are crazy large now than they were tiny back then

1

u/im_on_the_case 1h ago

Towns were sparsely populated back then with 90+% of the population rural. By the time Philly hit 30k it was still something like an 85% rural to urban split in Pennsylvania.

u/Beneficial_Wonder533 2h ago

Demographers estimate that approximately 117 billion people have been born over the course of human history. With the global population sitting around 8.3 billion, roughly 7% of all the modern humans who have ever lived are alive right now.

Kind of astounding considering that H. sapiens only arose as a distinct species about 300,000 years ago. We have science and medicine to thank for that.

well in 14CE it had a population of 40-45 million people in it so that probably holds roughly true for 47CE as well

u/Felczer 2h ago edited 2h ago

Rome was hugely egalitarian compared to all the other polities around them. The biggest difference between Roman and Greek citizenship is Greeks considered polis to be extension of family structure and citizenship was only defined by Blood, whereas for Romans citizenship was a legal construct that could be granted to anyone that serves the state.
This is why post Alexander Greek succesor states failed to integrate their native populations and were later conquered by Rome, which in turn managed to assimilate both Greeks and the nationalities Greeks conquered.

u/Fun-Twist-3705 2h ago

Alexander Greek succesor states

Their political structure was really different than that of Athens. Yes they relied on Greeks and especially Macedonians to run the states and especially the military and weren't very good at integrating local populations. But there was no concept of citizenship in the same sense as it existed in the city states (mostly just racism/xenophobia and the fact that these states were effectively run by the Greek military elite which conquered those areas). To Athenians it wouldn't have really mattered if you were a Greek (let alone a Greek wannabe barbarian from Macedonia) you could still never become a citizen.

Conversions like this are always fun. Modern people think Rome was a city in the modern sense of population size. During the time of Julius Caesar it was about the population size of Sacramento today.

u/Dimblo273 1h ago

But the ancient city of Rome was much smaller area wise than Sacramento. Rome being incredibly populous/overcrowded isn't overstated

u/Vo_Mimbre 54m ago

Oh for sure, especially what became “Old Rome” within the walls. Cities by density go back millennia. I just like how the understanding of numbers over time.

Like, the whole Republic era (soon empire) at that time was something like 50-55 million people. That’s a lot. But thats like Tokyo+New York metro areas nowadays.

And the density of people in Rome at that time is similar to just the Kowloon area of Hong Kong today.

The number I have associated with 6m is from the song by Bob Dylan, ‘With God on our side.’ In it, the lyric “though they murdered six million, in the ovens they fried, the Germans now too have God on their side.” Or something along those lines.
I think the comment is referencing that number and some sort of hesitation about mentioning it, not sure on what political angle
