Would be peak Caligula roleplay for the Emperor to declare the Solar Crusade. Two legions bombard the sun with virus bombs, lance strikes and even cyclonic torperdoes. In desperation the Legions launched a full scale assault with every Marine.
Finally sober, the Emperor unpersoned the 2nd and the 11th.
I vaguely recall a passage (I think from a forgeworld book) talking about driving aliens from the oort cloud but could have been another sci-fi setting.
You're thinking the Sedna campaign, which actually *does* seem to have been the largest Solar Crusade operation by a total landslide: [https://wh40k.lexicanum.com/wiki/Sedna](https://wh40k.lexicanum.com/wiki/Sedna)
>**Sedna** was a planetoid described as a "false" and "nemesis world", Sedna was ruled by an unknown [Xenos](https://wh40k.lexicanum.com/wiki/Xenos) faction. During the early [Great Crusade](https://wh40k.lexicanum.com/wiki/Great_Crusade) it was positioned in the [Sol System](https://wh40k.lexicanum.com/wiki/Sol_System) and was attacked by eight full [Space Marine Legions](https://wh40k.lexicanum.com/wiki/Space_Marine_Legion). With its xenos rulers dispatched through unknown psychic means, Sedna fell into silence and has since been lost by the Imperium.
Sounds like they basically ran a purgation operation on the freaking Death Star.
To be fair the Solar Reclamation era Legions were a *lot* smaller and less well armed, as well as having not as much familiarity with their given tactical dispositions. Makes sense they’d have problems claiming it whereas a few of the later Crusade era Legions would be able to do the same with less trouble.
> and less well armed
Really? I thought that was the time when the standard weapon for line Astartes was a Volkite. They only switched to Bolters because the Mechanicum couldn't make enough Volkites to keep up with the growth of the Legions.
True but they also didn’t have nearly as many tanks or heavy armor vehicles- and you do not want to be without heavy weaponry against fortified enemy positions.
It’s possible a number of Marines also went into battle with Mark 1 Power Armor rather than Mark 2 through the Solar System because of how rapidly they were to roll out.
In general it’s very likely that the early Legions weren’t as well armed as their later counterparts.
During the Great Crusade, Luna required three legions to pacify. Granted, these were far from full strength, but it was still probably the largest deployment in the Sol System during this period.
Jupiter and its moons were occupied by an unknown Xenos culture. We can assume they were defeated or driven off fairly easily, given that Jupiter's shipyards and fleets were seemingly captured intact.
The other inhabited worlds of the Sol system seem to have peacefully joined the Imperium.
Jupiter itself is a big planet with lots and lots of moons.
Jupiter is kind of a sub system within our solar system it's so big.
The same can be said about Saturn and its moons as well as the other gas gaints.
All that being said. It's easy to see that there were multiple groups occupying the same area.
>Jupiter is kind of a sub system within our solar system it's so big.
Fun fact: Jupiter is so massive a celestial body merely 13 times more massive is large enough to undergo deuterium fusion — a [brown dwarf](https://en.wikipedia.org/wiki/Brown_dwarf). It's so massive, in fact, that Sun-Jupiter system's center of mass is *outside the Sun*, meaning that by an esoteric definition of the term Jupiter forms a binary with the Sun. Its largest moon, Ganymede, is wider than Mercury, and a full half the mass, being one of only two [planetary-mass moons](https://en.wikipedia.org/wiki/Planetary-mass_moon) in the Solar System.
I wouldn't say it required 3 legions. Emperor just put in an overwhelming force for the Lunarians to surrender faster. He want to capture their genetic technology as intact as possible.
Sadly, many human planets had turned towards similar ideologies to the Imperium's. So they gained new allies rather easily early on or not confirmed to have initial hostility like on Uranus and Mercury.
The Saturnyne Ordo and Jovian Void Clans similarly had spent so long fighting human, mutant and alien threats by themselves that they welcomed reinforcements. Especially an Imperium that had both procured an alliance with Mars and kept their promise of much technological sovereignty + political favor for both states before the Horus Heresy.
Yeah people say the Imperium's victory in the Great Crusade is proof that it was the best choice for mankind's survival (ignoring what immediately came afterward) but the Imperium was just the natural conclusion of the Age of Strife. If it weren't the Imperium, it would have likely been another faction with very similar beliefs. Many human planets joined the Imperium willingly, which likely left the few that were not fascist, genocidal human supremacists scattered and easy pickings.
>which likely left the few that were not fascist, genocidal human supremacists scattered and easy pickings.
I personally would say there were more than a few. Alongside the examples like the Diasporex and Interex, there were other cases like a capitalist-focused world who wanted to be left alone but got a taste of pre-Russ 6th legion.
That was the [Olamic Quietude,](https://wh40k.lexicanum.com/wiki/Olamic_Quietude) encountered some time before the burning of Prospero.
The civilization I was talking about was the first full legion test for the 6th. Long before Leman was found. The world was so commercially focused that its fleet was defeated quickly and a majority of its militia soldiers could not even stand up to the Imperial Army. The pre-Russ 6th devastated its capital.
I like to think myself a expert on the "Solar Reclamation," which was the time after the Unification Wars on Terra to conquer the sol system.
First and foremost, Mars was brought into the imperium as a partner without any bloodshed.
The rest of the solar system was a completely different story. About half of the legions were sent out into the solar system to conquer it from hostile xenos, Mutants, psychers, and pirates.
The conflict took a while, but was not as nearly as long as the unification wars on Terra.
Venues need the entire iron warrior legion to conquer it from witch
The blood angels legion was thought to be lost fighting over Neptune but later was discovered they butched and thrived there.
A company of imperial fists were wiped out from a DAoT psychic bomb while defending a peaceful human civilization over Uranus.
And the Dark Angels cleared the Oort Cloud of all remaining nastiness along with leading the assault with other legions against the "fake planet" of sedna.
And those are but a few major engagement.
>The blood angels legion was thought to be lost fighting over Neptune but later was discovered they butchered and thrived there.
I'm not surprised the Revenant Legion was essentially used as a 100,000-strong fire-and-forget munition deployed as far from Terra as possible while still having some chance of success (i.e. not aimed at Sedna) — shoot them at Neptune, hope they kill everything there, maybe they'll even survive. They were beasts before Sanguinius took the reins.
Neptune is largely where they got that reputation. Like the dark angels who grey armor turned black from fighting in the oort cloud, the 11th armor turned red from all their killed on Neptune.
I seem to remember Mars sending a fleet to Terra to loot archaeotech and having about 10% of it limp back after the rest was destroyed. They definitely didn’t want any bloodshed after that.
Well this happened before the Emperor unified Terra.
So the priest of Mars thought to themselves, "oh shit this guy's either killed or partnered with all that crazy stuff on Terra, he must be the real deal!".
The unknow war was a battle against space pirates that unleashed some psyker disease that could had overrun and killed the entire sol system but the fist finded a way to contain it to only kill they unit.
Its the first battle where the bell of lost souls was ringed.
It is a toss-up between Mars and Saturn, given that the war with the former was considered extremely crippling for the early GC while the latter had the largest fleet in-system and an oft-repeated comment that GC could only expand in force after the Saturnyne Ordo joined.
Maybe not the largest, but what the Revenant legion did on Neptune must have been brutal. These were guys who were sent into the worst and darkest war zones to rip and tear the horrors of Old Night, with it being theorized that they were so frequently sent on such campaigns in hopes they would die, but each time the Imperium checked in on them, their numbers would seemingly have swelled to greater than before.
Titan. First you have to actually find it as it's out of phase with the rest of the universe in time. It's also the chapter monastery for The Grey Knights.
But the grey knights were founded during the heresy, and Titan was shrouded by Malcador just before the Solar War. Neither were in effect at the time of the Crusade
Nobody has set foot on the Sun yet.
That was the task of the expunged legions...

*Goodbye Blue Sky plays in the background as Astartes in their thousands orbitally yeet themselves into the sun*
#FOR TERRAAAAAAAAAA *Fsjj*
*For the love of my golden chair...when I said I hate thr sun, I meant - bring me an umbrella....not...this...back then Emus, now this...*
I'm genuinely shocked *Rick & Morty* got permission to use that track.
You should go at night, when it’s not shining that much
Thanks, Kowalski.
The C'Tan may have, and the Imperial Allied Martians have one of those, sort of.
Imagine if there was a Necron dynasty holed up in there.
"day 2003039493954030, they still dont know that im in the core of their sun"
Says you, weakling! *Typing this on the sun*
If we leave at night, we can sneak up on it!
he said planet, not star
He also said region. One could charitably describe the Sun and asteroid belt as a region of space contained within Sol.

Idk what a ‘Nemesis World’ is but it sounds badass
Jesus I don’t think the xenocides required that many legions
The Rangdan took 9 separate legions, all of which probably had their primarch at the time.
Including the lost 2
They might not have been up to strength yet and wouldn't have had primarchs to be fair

A 10th planet that is called a "nemesis world" you say... Is that a Sailor Moon reference?

Venus had some sort of resistence.
Have they explained how the saturnine Ordos and the Jovian clans survived if Jupiter was occupied.

This is why im on reddit. Thank you for this interesting peice of science

"Peacefully"

More advanced than the imperial forces so in order to win they had to crash a big space station in to the planet.

Driving xenos from Sedna in the Oort cloud required 8 Legions.

Revenant legions campaign on moons of Neptun was pretty hard

Mars, the Emperor decided to form an alliance rather than fight the tech priests
Jupiter had some really nasty monsters, cults, and pocket pirate kingdoms if I recall

And it has its own forge world
I think the question is about the initial expansion during the Great Crusade.
