The Historical Context of Jesus
Jesus was born a Jew in the Roman province of Judea around 4 BCE. At that time, being called "son of God" was not unusual, Roman emperors like Augustus used the title. But a poor Jew claiming that status was revolutionary. For a more comprehensive account of his life and teachings, see The Gospel of Matthew Explained: Jesus' Life, Teachings, and Legacy.
Jewish Foundations of Christianity
To understand Jesus, we must start with Judaism:
- Monotheism: The Hebrews developed belief in one true God (Yahweh)
- The Covenant: A deal between God and Abraham, with circumcision as the sign
- The Chosen People: Abraham's descendants were promised land and greatness
- Prophets: Messengers who warned people to follow God's path
Key characteristics of Yahweh:
- Singular (no other gods before Him)
- Transcendent and personal
- Involved in history (floods, wars, etc.)
- Demands moral righteousness and social justice
This tradition emerged from a rich ancient context, which you can explore in Crash Course World History: Hinduism, Buddhism, and Ancient India.
Jesus in First-Century Judea
By Jesus's time, Judea was under Roman control, ruled by Herod the Great and later Herod Antipater. Hellenistic influences (Greek theater, philosophy, rationalism) sparked backlash from Jewish groups:
- Sadducees
- Pharisees
- Essenes
- Zealots
Jesus of Nazareth was one of many preachers, but stood out for his:
- Charisma and loyal followers
- Reported miracles (not uncommon for the era)
- Radical message of peace, love, and justice
- Anti-authoritarian stance (e.g., "easier for a camel to pass through the eye of a needle than for a rich man to enter heaven")
The Romans crucified Jesus as a threat to their authority. (Note: The claim that Jews killed Jesus is historically inaccurate.)
Why Did Some Believe Jesus Was the Messiah?
- Jewish Messianic Tradition: Prophecies (e.g., Isaiah 53, Daniel 7:14) described a savior who would be misunderstood but bring a new kingdom
- Roman Oppression: Judea under Herod and Rome felt like "a time of trouble" needing deliverance
- Parallels with Roman Ideas: Virgil's poem about Augustus also described a "son of God" freeing the earth from fear
For a deeper look at this central Christian belief, read Understanding the Resurrection: Christian Faith’s Cornerstone. The story of Alexander the Great also shows how perceived "sons of God" shaped history; see Alexander the Great: Hero, Legend, or Just a Great Story? Crash Course World History.
Why Did Christianity Spread?
Three key historical reasons:
1. The Jewish Diaspora (66-73 CE)
- Jewish revolt against Rome failed
- Romans destroyed the Temple and expelled Jews from Judea
- Without a Temple, Judaism had to define itself more strictly
- Jesus's followers had to decide: remain Jews or become something new
2. Paul (formerly Saul of Tarsus)
- Received a vision on the road to Damascus
- Declared that followers of Jesus did NOT have to be Jews or follow Jewish laws
- Opened Christianity to non-Jews (Gentiles)
- As a Roman citizen, Paul could travel freely, spreading the message across the Mediterranean
3. The Roman Empire in Decline
- Christianity was born in a unified empire with a common language (Greek)
- Roman religion offered no afterlife; its gods seemed petty and squabbling
- Early Christians faced persecution (lions, etc.) but grew slowly
- Emperor Constantine legalized Christianity and later converted
- Once the emperor was Christian, the religion spread rapidly
For context on the earlier clash between this empire and its neighbors, see Persians vs Greeks: Rethinking Ancient History and Western Civilization.
Key Takeaways
- Jesus was a Jewish preacher whose message of justice resonated with the poor
- His followers believed he was the Messiah based on Jewish prophecies
- Christianity became a separate religion primarily due to Paul's decision to include non-Jews
- The Roman Empire's decline and Constantine's conversion enabled Christianity's rise to power
Open Letter: The Ichthys (Fish Symbol)
John Green addresses the ancient fish symbol (ICHTHYS), which was originally a secret code for Christians. It has since been revived as a popular car decal, even where Christianity is widely accepted.
This summary is based on Crash Course World History #11, hosted by John Green.
Hi there my name’s John Green; this is Crash Course
World History and today we’re going to talk about Jesus. So this is a Roman coin from around the time
Jesus was born in the Roman Empire, and it calls Augustus, the emperor, the son of God.
So let’s just state at the outset that in
4 BCE, being the son of God, or at least being
the son of a god was not such an unusual thing. But a poor Jew being the son of God — that
was news. [Theme Music]
Any understanding of Christianity has to start
with Judaism, because Jesus was born a Jew, and he grew up in the Jewish tradition. He
was one of many teachers spreading his ideas in the Roman province of Judea at the time,
and he was part of a messianic tradition that
helps us understand why he was thought of
not only teacher but something much, much more. Let’s go straight to the Thought Bubble
today. The people who would become the Jews, were
just one of many tribal peoples eking out
an existence in that not-very fertile crescent
world of Mesopotamia after the agricultural revolution. The Hebrews initially worshiped many gods,
making sacrifices to them in order to bring good weather and good fortune. But they eventually
developed a religion centered around an idea
that would become key to the other great western
religions. This was monotheism, the idea that there is
only one true god (or at least that if there are other gods around, they are total lameoids).
The Hebrews developed a second concept that
is key to their religion as well: the idea
of the covenant, a deal with God. The main man in this, the big macher was Abraham.
Not to make this too much of a scripture lesson, but it’s kind of hard to understand the
Jews without understanding Abraham, or Abram
as he was known before he had his big conversation
with God. Recorded in Genesis 17: "When Abram was ninety years and nine, the LORD appeared
to Abram, and said unto him, 'I am the Almighty God; walk before me, and be thou perfect.'
" And I’m a make a covenant with you and
a bunch of cool things will happen like you’re
gonna have kids and your descendants will number the stars and you can have all the
land of Canaan forever, it’s gonna be awesome. I’m paraphrasing by the way, Thought Bubble.
So God promised that Abram would have kids
with his wife even though the dude was already like 99, but there was a catch: "This is my
covenant, which ye shall keep, between me and you and thy seed after thee; every man
child among you shall be circumcised." Keep
it PG-13, Thought Bubble. Now that is asking a lot from a guy, especially
a 99-year-old geezer like Abram living in a time before general anesthesia. But those
were the terms of the deal, and in exchange
God had chosen Abraham and his descendants
to be a great nation. From this we get the expression that the Jews are the Chosen people. Thanks for keeping it clean, Thought Bubble.
So, some important things about this god: One, singularity. He — and I’m using the
masculine pronoun because that’s what Hebrew prayers use — does not want you to put any
gods before Him.
He is also transcendent, having always existed
and he is deeply personal – he chats with prophets, sends locusts, etc. But he doesn’t
take corporeal form like the Greek and Roman Gods do. He is also involved in history, like he will
destroy cities, and bring floods, and determine
the outcome of wars, and possibly football
games. Stan, no! FOOTBALL games! Probably most important to us today, and certainly
most important to Jesus, this god demands moral righteousness and social justice. So,
this is the god of the Hebrews, Yahweh, and
despite many ups and downs, the Jewish people
have stuck with him for- according to the Hebrew calendar, at least- over 5700 years. And He has stuck by them too, despite the
Jews being, on occasion, something of a disappointment
to him. Which leads to various miseries, and
also to a tradition of prophets who speak for God and warn the people to get back on
the right path lest there be more miseries. Which brings us back to our friends, the Romans.
By the time that Jesus was born, the land
of the Israelites had been absorbed into the
Roman Empire as the province of Judea. At the time of Jesus’s birth, Judea was under
the control of Herod the Great, best known for building the massive temple in Jerusalem,
that the Romans would later destroy.
And by the time Jesus died, an expanded Judea
was under the rule of Herod Antipater. Also, unhelpfully, known as Herod. Both Herods ultimately
took their orders from the Romans, and they both show up on the list of rulers who are
oppressive to the Jews, partly because there’s
never that much religious freedom in an empire. Unless you are, wait for it... The Mongols
[Mongoltage] or the Persians. Also, they were Hellenizers,
bringing in Greek theater and architecture,
and rationalism. And in response to those
Hellenistic influences, there were a lot of preachers trying to get the Jews to return
to the traditions and the godly ways of the past, including the Sadducees, and the Pharisees,
and the Essenes, and the Zealots.
And one of those preachers, who didn’t fit
comfortably into any of these four groups, was Jesus of Nazareth. Jesus was a preacher
who spread his message of peace, love and, above all, justice, across Judea over the
course of his actually average-length life for his time.
He was remarkably charismatic, attracting
a small but incredibly loyal group of followers, and he was said to perform miracles — although
it’s worth noting that miracles weren’t terribly uncommon at the time.
Jesus’s message was particularly resonant
to the poor and downtrodden and pretty radical in its anti-authoritarian stance. He said
it was easier for a camel to get through the eye of a needle than for a rich man to get
to heaven, he said the meek were blessed,
that the last would be first and the first
would be last — all of which was kind of threatening to the powers that be, who accordingly
had him arrested, tried and then executed in the normal method of killing rebels at
that time: crucifixion.
Also, just to put this question to bed, the
Romans crucified Jesus, because he was a threat to their authority. Later traditions saying that the
Jews killed Jesus? Very unfortunate, also, very untrue. We’re not going to discuss Jesus’s divinity,
because:
1. This isn’t a theology class, and
2. Flame wars on the Internet make me so uncomfortable that I have to turn to camera 2. Hi there camera
2, I’m here to remind you that 3. Fighting over such things, like fighting
over whether the proverbial cake is a lie,
rarely accomplishes anything, plus
4. What matters to us is the historical fact that people at the time believed that Jesus
was the Messiah, the Anointed One, the son of God. And they believed that he would return
some day to redeem the world.
Which leads us to two questions about Christianity: First, Why did this small group of people
believe this? And second, why and how did that belief become so widespread?
So why would people believe that Jesus was
the Messiah? First. The Jews had a long tradition of believing
that a savior who would come to them in a time of trouble. And Judea under the rule
of Herod and the Romans... definitely a time of trouble.
And many of the prophecies about this savior
point to someone whose life looks a lot like Jesus's. For instance, Isaiah 53 says the
person will be misunderstood and mistreated, just like Jesus was: “He was despised, and
rejected by men; a man of sorrows, and acquainted
with grief: and as one from whom men hide
their face he was despised; and we didn't respect him.” And a lot of the prophecies like Daniel 7:14,
for instance, explained that when the Messiah comes there will be this awesome, new, everlasting
kingdom. And that had to sound pretty good
to people who’d had their autonomy taken
away from them. So some religious Jews saw Jesus in those
prophecies and came to believe either during his life or shortly thereafter, that he was
the messiah. Most of them thought the new
everlasting kingdom was right around the corner,
which is probably why no one bothered to write down much about the life of Jesus for several
decades, by which time it was clear that we might have to wait a bit for this brilliant
new everlasting kingdom.
I should note, by the way, that the idea of
a messiah was not unique to the Jews at the time. Even the Romans got in on the action,
for instance, the Roman poet Virgil wrote of a boy who: “Shall free the earth from
never-ceasing fear, he shall receive the life
of gods, and see Heroes with gods commingling.”
Sound familiar? But Virgil was writing about Emperor Augustus
in that poem, not Jesus, which points again to the similarities between the two. Both
called sons of God. Both sent to free the
earth from never-ceasing fear. But one ruled
the largest empire in the world; and the other believed that empire, and the world, needed
to change dramatically. So why did the less wealthy and famous son
of God become by far the more influential?
Well, here are three possible historical reasons: Reason #1: The Romans continued to make things
bad for the Jews. In fact, things got much worse for the Jews, especially after they launched
a revolt between 66-73 CE, which did not go well.
By the time the dust settled, the Romans had
destroyed the Temple and expelled the Jews from Judea, beginning what we now know
as the Jewish Diaspora. And without a Temple or geographic unity,
the Jews had to solidify what it meant to
be a Jew and what the basic tenants of the
religion were. This forced the followers of Jesus to make a decision: were they going
to continue to be Jews following stricter laws set forth by rabbis, or were they going
to be something else.
The decision to open up their religion to
non-Jews, people who weren’t part of the covenant, is the central reason that Christianity
could become a world religion instead of just a sect of Judaism. And it probably didn’t
hurt that the main proponent of sticking with
Judaism was James, Jesus’s brother, who
was killed by the Romans. Reason #2: Is related to Reason #1 and it’s
all about a dude named Saul. No, not that Saul. Yes, Saul of Tarsus, thank you.
Saul, having received a vision on the road
to Damascus, became Paul and began visiting and sending letters to Jesus followers throughout
the Mediterranean. And it was Paul who emphatically declared that Jesus followers did NOT have
to be Jews, that they did not have to be circumcised
or keep to Jewish laws or any of that stuff. This opened the floodgates for thousands of
people to convert to this new religion. And the other thing to remember about Paul is
that he was a Roman citizen, which meant that
he could travel freely throughout the Roman
Empire. This allowed him to make his case to lots of different people and facilitated
the geographic spread of Christianity. Oh, it’s time for the open letter? Alright.
An open letter, to the fish.
But first, lets see what’s in the secret
compartment today. Oh, Stan. It’s my favorite album Jesus Christ Superstar, finally available
in my favorite format, the cassette. Did I color-coordinate my shirt to Jesus Christ
Superstar? Yes.
Dear Ichthys, So check this out: In the first
century when it was still super underground and hipster to be a Christian, you were a
secret symbol of Christianity, used to kind of hide from the Romans. Ichthys, the Greek
word for fish, was an acronym and it was a
super clever way to talk about religion without
anyone knowing that you were talking about it. But you’ll never guess what happened - even
in places where it’s completely fine to talk about Christianity now and to use, you
know, regular Christian symbols, like the
cross, you have had a huge resurgence thanks
to the plastic automobile decal industry. I mean seriously, Ichthys, I haven’t seen
a comeback like this since Jesus. Best wishes, John Green
And lastly, Christianity was born and flourished
an empire with a common language that allowed for its spread. And crucially, it was also
an Empire in decline. Like even by the end of the first century
CE, Rome was on its way down. And for the
average person, and even for some elites,
things weren’t as good as they had been, if fact they were getting worse so fast that you
might have thought the end of the world was coming. And Roman religion offered no promise of an
afterlife, and a bunch of squabbling whiny
gods - sorry if I offended adherents to Roman
religion, but seriously, they squabble. So even though early Christians were persecuted
by the Roman Empire and sometimes fed to the lions and other animals, the religion continued
to grow, albeit slowly.
But then as the Roman decline continued, Emperor
Constantine allowed the worship of Jesus and then eventually converted to Christianity
himself. And then the religion really took off. I mean, Rome wasn’t what it used to
be, but everybody still wanted to be like
the Emperor. And soon enough there was a new
son of God on coins. Thanks for watching. See you next week. Crash Course is produced and directed by Stan

Jesus was born a Jew around 4 BCE in the Roman province of Judea, which was under Roman control and ruled by Herod the Great. The region was heavily influenced by Hellenistic culture, and various Jewish groups—like the Pharisees, Sadducees, and Zealots—reacted differently to Roman rule. Jesus stood out as a charismatic preacher offering a radical message of peace, love, and justice, which challenged both religious authorities and Roman power, ultimately leading to his crucifixion.
Jesus's teachings were deeply rooted in Jewish monotheism, the covenant with God, and prophetic traditions that promised a savior or Messiah. Many Jews at the time saw Roman oppression as a 'time of trouble' needing deliverance, and Jesus's actions—including reported miracles—aligned with prophecies from books like Isaiah and Daniel. His followers interpreted these parallels, along with his anti-authoritarian stances, as evidence that he was the promised Messiah who would bring a new kingdom.
Paul, originally a persecutor of Christians, experienced a vision on the road to Damascus and became a key evangelist. He declared that followers of Jesus did not need to follow Jewish laws like circumcision or dietary restrictions, making the faith accessible to non-Jews (Gentiles). As a Roman citizen, Paul traveled freely across the Mediterranean, spreading this inclusive message and establishing Christian communities, which was crucial for the religion's rapid expansion beyond Jewish circles.
Christianity benefited from the Jewish Diaspora after the failed revolt in 66-73 CE, which forced followers to define their identity separately from Judaism. Paul's teachings opened the faith to Gentiles, and the Roman Empire's unified infrastructure—common Greek language and trade routes—facilitated travel. Additionally, Roman religion lacked a compelling afterlife concept, and persecution often strengthened believers' resolve. Emperor Constantine's eventual conversion and legalization of Christianity in the 4th century allowed the religion to spread rapidly as the imperial faith.
Jesus was crucified by Roman authorities as a perceived threat to their power, given his growing following and anti-establishment teachings. The Roman governor Pontius Pilate ordered the execution, and it is historically inaccurate to claim Jews killed Jesus. The tense political climate under Herod's rule and Roman occupation created a volatile environment where any messianic figure challenging the status quo was seen as a potential rebel leader, leading to swift punishment.
During the Roman Empire's decline, its traditional religions—which offered no afterlife and depicted gods as petty—lost appeal, while Christianity provided hope and community. Although early Christians faced severe persecution, they grew steadily. Emperor Constantine's conversion in the 4th century and his legalization of Christianity through the Edict of Milan were turning points. Once the emperor embraced the faith, it gained official support, leading to rapid growth and eventual establishment as the state religion.
The fish symbol, derived from the Greek word ICHTHYS (an acronym for 'Jesus Christ, Son of God, Savior'), was initially used by early Christians as a secret code to identify each other during persecution. It allowed believers to meet and worship without detection. Today, the symbol has been revived as a common car decal or emblem, even in regions where Christianity is widely accepted, serving as a historical reminder of the faith's underground origins and enduring identity.
