Overview: The Roman Republic and the Rise of Empire
John Green explains that the Roman Republic's famous balance of monarchy, aristocracy, and democracy, praised by historian Polybius, ultimately failed due to imperial expansion and powerful generals. The central question: Did Julius Caesar destroy the republic, or was it already doomed? This question echoes similar debates about the collapse of other ancient civilizations, such as those explored in Mesopotamia: Cradle of Writing, Taxes, and the First Empires.
The Structure of the Roman Republic
- Senate: Elite legislators who set policy for consuls, chosen from patrician (aristocratic) families.
- Consuls: Two co-chief executives elected annually to check each other's ambition.
- Checks on Power: One-year terms; a 10-year ban on serving as consul again after a term.
- Dictator: Temporary emergency ruler, modeled after Cincinnatus (who famously returned to farming).
- Social Classes: Patricians (small aristocratic elite) vs. Plebeians (everyone else).
Julius Caesar's Rise to Power
- Born ~100 BCE via Caesarean section into a leading family.
- Served in army and Senate; rose through ranks, becoming governor of Spain.
- First Triumvirate (60 BCE): Alliance with Crassus (Rome's richest man) and Pompey (powerful general).
- Conquests: Governor of Gaul, conquered rest of Gaul, invaded Britain.
- Crossing the Rubicon (49 BCE): Defied Senate's recall order, brought army to Rome, famously saying "The die is cast."
- Dictator for Life: Pursued reforms like land pensions for soldiers, debt restructuring, and calendar reform.
- Assassination (44 BCE): Stabbed 23 times by senators led by Brutus and Cassius.
Key Arguments: Did Caesar Destroy the Republic?
- Yes: He seized power, subverted republican norms, started civil wars, and changed the constitution.
- No: Precedents existed, General Marius (5 consecutive consulships, army loyalty to him, not Rome) and General Sulla (marched on Rome, became dictator in 81 BCE).
- Empire Before Emperor: Rome had imperial characteristics (unified government, military expansion, diverse subject peoples) long before Augustus. By 201 BCE, after the Second Punic War, Rome controlled Spain and was already an empire. This pattern of imperial expansion transforming political systems has parallels with the Greek-Persian conflicts discussed in Persians vs Greeks: Rethinking Ancient History and Western Civilization.
- Empire Created Emperors: Military expansion needed powerful generals; diverse peoples were loyal to generals, not the republic. The need for new land for retired legionnaires drove continuous conquest, concentrating power in one man.
Conclusion: Empire, Not Caesar, Killed the Republic
- The Roman Republic was already dead by the time Caesar seized power. Imperial expansion and the rise of all-powerful generals made the republic unsustainable. Augustus simply formalized what had already existed for 200 years. The real lesson: empires demand concentration of power, which inevitably destroys republican government. This dynamic of power concentration reflects broader patterns seen in What Is a Civilization? The Indus Valley & Crash Course History.
Hi, I'm John Green. This is Crash Course World History, and today we're going to learn about the Roman Empire, which of
course began when two totally non-fictional twins, Romulus and Reheis, who'd been raised by wolves, founded a
city on seven hills. Mr. Green, Mr. Green, what what does SpQR stand for? It means shut, pie, hole, quickly, rap
scallion. No, it means senus populace romanist, one of the mottos of the Roman Republic. So, today we're going to do
some old school great man history and focus on Julius Caesar while trying to answer a question. When, if ever, is it
okay to stab someone 23 [Music] times? Shakespeare answers that question
by saying that Roman senators killed Caesar because he was going to destroy the Roman Republic. But even if that's
true, we still have to answer whether a the Roman Republic was worth preserving and b whether Caesar actually destroyed
it. One of the things that made the Roman Republic endure both in reality and in the imagination was its balance.
According to the Greek historian Palibius, the three kinds of government, monarchy, aristocracy, and democracy,
were all found united in Rome. And it was no easy thing to determine with assurance whether the entire state was
an aristocracy, a democracy, or a monarchy. At the heart of this blended system was the Senate, a body of
legislators chosen from a group of elite families. Rome was divided into two broad classes. the Petricians, a small
group of aristocratic families, and the Plebeians, basically everyone else. The Senate was sort of a mixture of
legislature and giant advisory council. Their main job was to set policy for the consoles. Each year, the Senate would
choose from among its ranks two co-consils to serve as sort of the chief executives of Rome. There needed to be
two so that they could check each other's ambition and also so that one could, you know, take care of Rome
domestically while the other was off fighting wars, conquering new territory. There were two additional checks on
power. First, the one-year term. I mean, how much trouble can you really do in a year, right? Unless you're the CEO of
Netflix. I mean, he destroyed that company in like two weeks. And secondly, once a senator had served as console, he
was forbidden to serve as console again for at least 10 years. Although that went a little bit like how you say
you're only going to eat one Chipotle burrito per week and then there are a few exceptions and then all of a sudden
you're there every day. And yes, I know guacamole is more. Just give it to me. But right, we were talking about the
Romans. So the Romans also had a position of dictator, a person who would take over in the event that the republic
was in imminent danger. The paradigm for this selfless Roman ruler was Catis, a general who came out of comfortable
retirement at his plantation, took command of an army, defeated whatever enemy Rome was battling, and then laid
down his command and returned to his farm safe in the knowledge that one day the second largest city in Ohio would be
named for him. If that model of leadership sounds familiar to Americans, by the way, it's because George
Washington was heavily influenced by Catis when he invented the idea of the two-term president. So, along comes
Caesar gas. No, it's gas. I know from Battlestar Galactica. Gas Julius Caesar was born around 100 B.CE to one of
Rome's leading families. His birth was somewhat miraculous, requiring a surgical procedure that we know today as
a Caesar Ian section. Coming as he did from the senatorial class, it was natural that Caesar would serve in both
the army and the senate, which he did. He rose through the ranks. And after some top-notch generaling and a gig as
the governor of Spain, he decided to run for console. In order to win, Caesar needed financial help, which he got from
Craas, one of Rome's richest men. Craas ran a private fire company whose business model was essentially, "Hey, I
notice your house is on fire. Give me some money and I'll help you out with that." Caesar succeeded in becoming
console in 59 B.CE. and thereafter sought to dominate Roman politics by aligning himself with Cassus and also
with Rome's other most powerful man, the general Pompy. You'll no doubt remember Pompy from his fascination with
Alexander the Great. Pompy, Cassus, and Caesar were the so-called first triumvirate, and the alliance worked out
super well for Caesar. Not so well for the other two. Let's go to the thought bubble. After a year as console that
included getting the Senate to pass laws largely because of intimidation by Pompy's troops, Caesar landed the
governorship of Gaul, at least the southern part of Gaul that Rome controlled. He quickly conquered the
rest of Gaul and his four loyal armies, or legions as the Romans called them, became his source of power. Caesar
continued his conquests, invading Britain and waging another successful war against the Gauls. While he was
away, Craas died in battle with the Parththeians. And Pompy, who had become Caesar's rival and enemy, was elected
consul. Pompy and the Senate decided to try to strip Caesar of his command and recall him to Rome. If he returned to
Rome without an army, Caesar would have been prosecuted for corrupt counseling and also probably exceeding his
authority as governor. So instead, he returned with the 13th Legion. He crossed the Rubicon River, famously
saying, "The dye is cast." Or possibly, "Let the dye be cast." Sorry, thought bubble sources disagree. Basically,
Caesar was invading his own hometown. Pompy was in charge of Rome's army, but like a boss, fled the city, and by 48
B.CE. Caesar was in total command of all of Rome's holdings, having been named both dictator and consul. Caesar set out
to Egypt to track down Pompy, only to learn that he'd already been assassinated by agents of the Pharaoh
Talamy. Egypt had its own civil war at the time between the Pharaoh and his sister/wife Cleopatra. Tommy was trying
to curry favor with Caesar by killing his enemy, but Caesar was mad in that the only person who gets to tease my
little brother is me kind of way, except with murder instead of teasing. So Caesar sided with and scutily poofed
with Cleopatra. Thanks thought bubble. Cleopatra went on to become the last pharaoh of ancient Egypt and then bet on
Mark, "I am the wrong horse Anthony instead of emperor. There is a baby attached to my leg Augustus." But before
all that, Caesar made his way back from Egypt to Rome, stopping off to defeat a few kings in the east on his way and was
declared dictator again. That position was later extended for 10 years and then for life. He was elected console in 46
B.CE and then again in 45 B.CE. this last time without a co-consul. By 45 B.CE. Caesar was the undisputed master
of Rome and he pursued reforms that strengthened his own power. He provided land pensions for his soldiers,
restructured the debts of a huge percentage of Rome's debtors, and also changed the calendar to make it look
more like the one we use today. But by 44 B.CE, many senators had decided that Caesar controlled too much of the power
in Rome. And so they stabbed him 23 times on the floor of the Roman Senate. Caesar was duly surprised about this and
everything, but he never said at two brute when he realized Brutus was one of the co-conspirators. That was an
invention of Shakespeare. The conspirators thought the death of Caesar would bring about the restoration of the
Roman Republic. And they were wrong. For one thing, Caesar's reforms were really popular with the Roman people who were
quick to hail his adopted son, Octavian, as well as his second in command, Mark, I am the wrong horse, Anthony, and a d
named Lepedus, as a second triumvirate. This triumvirate was an awesome failure, degenerating into a second civil war.
Octavian and Anthony fought it out. Anthony being the wrong horse lost. Octavian one changed his name to Caesar
Augustus, became sole ruler of Rome, attached a baby to his leg, adopted the title emperor, and started printing
coins identifying himself as Divinilious, the son of God. More on that next week. Although Augustus tried
to pretend that the forms of the Roman Empire were still intact, the truth was he made the laws and the Senate had
become nothing more than a rubber stamp. Which reminds me, it's time for the open letter. Movie magic. An open letter to
the Roman Senate. Oh, but first, let's check what's in the secret compartment. Oh, it's a harmonica. Stan, do you want
me to play some old Roman folk songs? Very [Music]
well, Stan. I just want to thank you for doing such a good job of overdubbing there. Dear Roman Senate, whether you
were rubber stamping the laws of Emperor Augustus, or stabbing Caesar on the floor of your sacred hall, you were
always doing something. I don't want to sound nostalgic for a time when people lived to be 30, a tiny minority of
adults could vote, and the best fashion choice was bed sheets. But oh my god, at least you did something. Your Senate was
chosen from among the Petrician class. Our Senate here in the United States is chosen from among the obstructionist
class. But don't get me wrong, Roman Senate, you were terrible. Best wishes, John Green. So, did Caesar destroy the
Roman Republic? Well, he started a series of civil wars. He seized power for himself. He subverted the ideas of
the republic. He changed the constitution. But he's only really to blame if he was the first one to do
that. And he wasn't. Take the general Marius for instance, who rose to power on the strength of his generalship and
on his willingness to open up the army to the poor, who were loyal to him personally and not to Rome, and whom he
promised land in exchange for their good service in the army. This of course required the Romans to keep conquering
new land so they could keep giving it to new legionnaires. Marius was also console five times in a row 60 years
before Caesar. Or look at the Roman general Sullah who like Marius ensured that his armies would be more loyal to
him personally than to Rome but who marched against Rome itself and then became its dictator executing thousands
of people in 81 B.CE 30 years before Caesar entered the scene. There's another way of looking at this question
altogether. If we dispense with great man history, maybe Rome became an empire before it had an emperor. Like remember
the Persian Empire? You'll recall that that empire had some characteristics that made it imperial, like a unified
system of government, continual military expansion, and a diversity of subject peoples. The Roman Empire had all three
of those characteristics long before it became the Roman Empire. Like Rome started out as a city, and then it
became a city-state and then a kingdom and then a republic. But that entire time it was basically comprised of the
area around Rome. By the 4th century B.C.E. Rome started to incorporate its neighbors like the Latins and the
Atruscans. And pretty soon they had all of Italy under their control. But that's not really diversity of subject peoples.
I mean nothing personal Italians but you know you have a lot of things in common like the constanticulations. If you want
to talk about real expansion and diversity, you got to talk about the Punic Wars. These were the wars that I
remember primarily because they involved Hannibal crossing the Alps with freaking war elephants, which was probably the
last time that the elephants could have risen up and formed their awesome secret elephant society with elephant planes
and elephant cars. In the first Punic War, Rome wanted Sicily, which was controlled by the Carthaginians. Rome
won, which made Carthage cranky. So, they started the second Punic War. In 219 B.C.E., Hannibal attacked a Roman
town, then led an army across Spain, and then crossed the freaking Alps with elephants. Hannibal and his elephant
army almost won, but alas, they didn't. And as a result, the Romans got Spain. People in Spain are definitely not
Romans, despite Russell Crow's character in Gladiator, which means that by 2011 B.CE., Rome was definitely an empire.
The Third Punic War was a formality. Rome found some excuse to attack Carthage and then destroyed it so
completely that these days you can't even find it on a map. Eventually, this whole area and a lot more would be
incorporated into a system of provinces and millions of people would be ruled by the Roman Empire. And it's ridiculous to
say that Rome was a republic until Augustus became Rome's first official emperor because by that time, Rome had
been an empire for almost 200 years. There's a reason I'm arguing that the death of the republic came long before
Caesar and probably around the time that Rome became an empire. If anything destroyed the idea of republic in Rome,
it was the concentration of power into the hands of one man. And this man was always a general. I mean, you can't
march on Rome without an army after all. Why were there such powerful generals? Because Rome had decided to become an
empire. And empires need to expand militarily. Particularly, the Roman Empire needed to expand militarily
because it always needed new land to give its retired legionnaires. That expansion created the all powerful
general, and the incorporation of diverse peoples made it easier for them to be loyal to him rather than to some
abstract idea of the republic. Julius Caesar didn't create emperors. Empire created them. Next week, we'll be
discussing Christianity, so that shouldn't be controversial. Until then, thanks for watching. Crash Course is

Jeez. Yikes. Everything is fine.
According to the video, Caesar did not single-handedly destroy the Republic. The Republic was already collapsing due to imperial expansion and the rise of powerful generals before him. Precedents like Generals Marius and Sulla—who marched on Rome—showed the system was failing, and Caesar's actions were the final blow to an already doomed structure.
The Republic consisted of a Senate (aristocratic policy-makers) and two annually elected consuls who checked each other's ambition. Consuls served one-year terms and were banned from re-election for ten years. A temporary dictator could be appointed in emergencies, modeled after Cincinnatus, who famously returned to farming after his term.
Caesar rose through military and political ranks, forming the First Triumvirate with Crassus and Pompey. His conquests in Gaul and Britain boosted his popularity. When the Senate ordered him to disband his army, he defied them by crossing the Rubicon into Rome, sparking a civil war. He was then declared 'Dictator for Life' and pursued reforms before being assassinated in 44 BCE.
Those arguing 'yes' point to Caesar seizing power, subverting republican norms, and starting civil wars. Those arguing 'no' note that precedents existed—General Marius held five consecutive consulships and General Sulla marched on Rome—proving the Republic was already unstable. The real cause was imperial expansion, which concentrated power in generals long before Caesar.
The video argues that Rome had imperial characteristics (like controlling Spain) as early as 201 BCE, long before Caesar or Augustus. Military expansion required powerful generals, and diverse conquered peoples became loyal to these generals, not the Republic. The need for new land for retired soldiers drove continuous conquest, making a single, all-powerful ruler inevitable.
Patricians were the small aristocratic elite who controlled the Senate and most political offices, while Plebeians were the common majority. This division created tension, as plebeians demanded more representation. The Republic's checks on power, like the tribunate (not fully detailed in the video), were partly a response to these class struggles, though they ultimately failed to prevent concentration of power.
Caesar enacted land pensions for soldiers, debt restructuring, and calendar reform (the Julian calendar). These reforms, while popular with the masses and veterans, bypassed traditional senatorial approval and centralized authority in one man. His actions demonstrated that the Republic's democratic checks were already too weak to prevent a single ruler from reshaping the government, accelerating the transition to empire.
