For the book, we share thoughts on this. They were not a force that could kill, and they would just cause chaos on both sides. For the movies, Aragorn had to weigh the fact that these powerful spirits were only begrudgingly following his orders. After the battle, they practically DEMAND to be released. What if Aragorn had said no? This spirit army could simply run through his like they did the enemy. Yes, they'd still be damned, but do you think Aragorn could really chance that? Plus, Aragorn is a man of honor. After the battle, they did not have a clear path of action yet. They had not decided to march on Mordor, and could still have just set siege to keep Sauron's army bottled up. So in that moment, not knowing what was next, he simply went with what he felt was right and cut them loose.

Aragorn was a man of honour who was accustomed to keeping his promises. Besides, breaking a promise to dead supernatural spirits could have nasty consequences, such as Sauron somehow gaining control over the ghosts. Dead spirits seem to be his thing, and a broken oath could work in his favour.

My theories at least in the movies: 1. They are powerless in Mordor and a chance to be corrupted and tormented. 2. Their power can only go so far. The mountain being their source. (They cannot reach Mordor going back to number 1)

If i remember correctly, Isildur only called them to a single battle, which they refused, and were thus cursed. After repaying that single battle, at Pelargir, their broken oath was fulfilled, and they could finally be at peace. (I havent watched the vid yet so idk if its mentioned)

The problem was that the Oathbreakers had worshiped Sauron during the Dark Years, which is why they failed to fulfill their oath to Isildur in the first place. Bringing them to Mordor to use against Sauron would have posed the possibility that Sauron could return them to their allegiance to him, and then used them against Aragorn and the rest of his forces. Aside from being a very great gamble, it also was stretching the initial oath quite a bit further. They had been summoned by Isildur to fight for him against Sauron's forces, and by attacking and destroying the Corsairs of Umbar, they had done that, and basically fulfilled their oath. Overall, Aragorn continuing to attempt to use the Oathbreakers put at risk all what he was working for, and that was to be recognized at the true King of Gondor.

The oath that the oathbreakers gave was to defend Gondor in it’s time of need not to fight a prolonged war Aragorn gave his word if the oathbreakers come to the aid of Gondor he would release them the oath breakers fulfilled their Vow and Aragorn being a man of honor kept his vow and release them after the battle. If he had continue to use the oath breakers it would’ve been no different than Isildur keeping the ring. Both were selfish purposes.

What do you mean I messed up th title screen?!?

Perfect. I think you made valid points and covered all of them. I also tend to think the Oath-Breakers were perfect against a completely human host like the one at Pelargir (Umbarians and Haradrim) but would have seriously reduced effects against Orcs and other creatures of the enemy who were themselves partly magical and quite used to the Phantoms, Wraiths, Ghosts and creatures of terror that Sauron employed regularly. I think it would have far less effect, and eventually no effect on such races and classes of beings.

Great points! I can't say that question never bugged me, as it always seemed extremely useful to have an army of ghosts in your back pocket at any time. But then again, like you said, that would be damaging to Aragorn, and to his kingdom. I suppose the lure of power is what tempted me to think of all the good Aragorn could achieve with the undead army of the Oathbreakers... but that's the same line of reasoning we see with Boromir and a few others over a certain object of power : "Imagine what we could do with this, we shouldn't just throw it away!" So basically, using the Army of the Dead, even to free Middle-earth from Sauron, would clash not only with Tolkien's morality and themes, but with the reality of the situation as well, as you've demonstrated.

The change to the Oathbreakers in the movie could either be for the "awe" feeling of them sweeping the fields and city, or it could be to avoid hiring more extras for human reinforcements.

Also it doesn't make much sense to scatter the orcs into Mordor when the whole point of you being there in the first place is to lure out the orcs out of Mordor

Also imagine the sheer willpower it took Aragon to control the Dead which inflicted terror upon everything around

Do you think Sauron, being a necromancer and all, could have taken control of the Army of the Dead? Or at least disbanded it to some degree?

You say that the ghosts and the fear they spread are like a "party trick" that only works once, and when the enemy realises the ghosts can't hurt them they stop feafing them. I disagree. In Return of the King, Legolas describes how the corsairs are so afraid of the ghosts that they throw themselves into the water and drown upon seeing them. The fear drives them mad. This to me suggests that the fear the ghosts spread is more than mundane fear, it's some sort of supernatural terror that can only be resisted by those with extraordinary willpower. This is why Aragorn tells the men of Gondor to follow him from afar, rather than simply explaining the ghosts are on their side; the aura of terror the ghosts emit is so powerful that lesser men simply cannot withstand it no matter how much they try Legolas also states that the ghosts had weapons but they didn't use them, for fear was the only weapon they needed. (Note that Legolas doesn't say they couldn't use those weapons, just that he didn't see them use them). This would be an odd thing to say if the fear was an easy thing to counter, in that case they definiteky could use another weapon As for why Aragorn released them when he did, I think it's the collateral damage effect. He wanted his arrival at Minas Tirith to be remembered as a day when the new King saved the city, not as a day when he brought an army of undead abominations and sent his own side into chaos. Also the ships he used needed men to row the oars, and if they all fled or killed themselves out of fear of the ghosts Aragorn wouldn't have arrived on time if at all

I think the fact Aragon only used them at Pelargier in what effectively is a suprise attack, where their ability to cause fear would have the best impact, as they had the suprise and fear factor on their side is the best evidence that the army of the dead can't hurt people. As even if the Army of the Dead doesn't scare all the corsairs away they would have suprised and scared a good part of them away at least making any fight the Grey Company might have had to to fight a lot eaiser.

I never thought that the oathbreakers could have had much effect against Nazgul and Sauron. I also thought that their oath bound them to that specific land, not all the land of Gondor. I agree they amounted to a kind of magic trick.

I just wanna point that "they're taking the Oathbreakers to Mordor" can fit the cadence of "they're taking the Hobbits to Isengard."

(Another reason why you might not want to bring an army of spirits to Mordor…) Sauron is named The Necromancer. Is he able to control the dead? (Like hiding the women and children in the Crypts of Winterfell while the dead-raising army marches on them, in Game of Thrones…)

I have always felt like failing to fight against Sauron in Mordor could only be repaid by… fighting against Sauron in Mordor

Not to mention that Sauron being the Necromancer might would have managed to overcome and control the Oathbreakers. P.S. And remember what at 12:15?

Nice video. As an in-universe explanation it makes sense. For me though the role of this in the books was in defining Aragorn's character. Now we are nearing the Aragorn-as-king part of the story, it was significant that he only required the oathbreakers to do what was just, even in a time of great need.

I always imagined Aragon leaving the choice to the oath breakers to stick with him after their battle.

See i always thought the Aragon never took them as the Army of the Dead was Aragon is trying to make himself look like a noble and heroic king worthy of sitting on the Throne of Gondor and its kind of hard to sell the idea your noble and heroic to the people of Gondor and Rohan when you have an army of ghosts as its kind of dark and more in line with Sauron and assuming Denethor doesn't self imolate himself he could make a compelling case that Aragon is corrupted and it would be hard to argue against that reason.

Great video! You came up with several good points

Open to any lore-based corrections on this, but I would speculate that Tolkien inserted a traditional and conservative Christian message within this narrative. At first glance from this perspective, there's an idea that attempting to communicate with dead spirits is strictly forbidden (even if they are real). However, this host seemed unique in circumstance, more undead than dead, like the idea of interceding for those in Purgatory; only to be done very carefully from a religious standpoint (ie. In Catholicism by a saint and by means outlined by an apostolic church). So in this case, not only did there need to be rightful authority for the process, but the undead seemed to also represent a power of giving grace and forgiveness to lost brethren, which helps the Kingdom of God's message of love spread, thus defeating evil as even those lost, the faithless, and cursed contribute to the cause in a way. The undead here obviously weren't intended to be revered as heroes, but bring glory to a higher message aligned with the idea in 2 Corinthians 2:9.

Very good video about the limits of using the oathbreakers.

Our Question for the past 18 years has been fulfilled. Thanks for releasing us Darth Gandalf. It's time to Rest.

You over thought this. They fulfilled their original oath, and Aragon is portrayed as nearly perfectly honorable. He called upon them to fulfill their oath, and once they did so, Aragon released them from their curse. It was a way to also put more shine on how truely good Aragon was.

That was a great explanation. As a writer myself, I think your analytical skills of Tolkien's world of Arda is wonderful. I thought the same about everything except the tieback to oaths in the Silmarrillion and the fact of Morgul host figuring it out. I thought the Nazgul might figure it out that they may not be able to harm anyone physically

Aragorn gave his word to free them after Minas Tirith. Breaking his word might have create unpredictable consequences. Such as making the army turn against him, and cause untold damage, or worse. Side with Sauron who might give them the promise of freedom, and considering his power i am not sure, if he can't carry it out. In short. Doing that would have been risky as fuck.

2:50 "this land" - Smart Aragorn, here it comes in handy that amongst the extensive lessons of lore and Quenya in Imladris he also read four semesters of law. So here with the oathbreakers he cunningly kept a loophole open for possible court battles in the UCLU that might ensue later (United Courts of the Living and Undead)

Also, it seems to me that there was a clear message intended in all their strategies, both to Sauron and the people of Middle Earth. That message being that the might of Sauron can and should be overthrown by the strength of the mortal races, not by sorcery. And so it was. The battle of the Pelennor Fields was won by the strength of men and the ring was destroyed by the hobbits. This would have greatly raised the courage and hope of the people of Middle Earth, as they could not rely on the higher powers forever; and by the end, they knew they didn't have to. The power of the other rings diminished and the high elves departed along with Gandalf and Middle Earth was left in the care of the mortal races, with a renewed sense of hope, unity and faith in themselves.

There is a simpler explanation; Aragorn didn’t know they were going to attack Mordor until after he had already released the Oathbreakers.

"and remember..." what?

I see the Oath breaker like the One Ring. Aragorn made promise and he resisted the urge to abuse power. Which really is the point of LOTR

Because one does not simply walk into Mordor with an army of oathbreakers.

If Aragorn did not release them after the battle at Pelargir, this might have made him a Dark Lord himself. What gives Aragorn his moral authority is that he does the right thing.

Take an army of ghosts into a realm ruled by Sauron who posed as the Necromancer of Dol-Guldar? Freeing them prevented Sauron seizing control of them and stripped him of that resource in the process. Kept his word is a pretty big deal and meant his own forces trusted him even more as a result.

I just thought it would be a bad idea to have an army of ghosts invade a land ruled by a being that was once called "the Necromancer".

If memory serves, elves did not fear the spirits of men (ghosts). If that was the case it may have been the same for orcs (which are corrupted elves). So their effectiveness at Pelennor Fields would be negligible.

A bit strange then to have them in the movie adaptation at Pelennor Fields as well as Minas Tirith.

Another angle, is that you remember that the oathbreakers also secretly worshipped Sauron and that’s why they turned on Isildur. There is a possibility, however slight, that they may turn on Aragorn if they made it to the black gate.

I think I recall reading somewhere on a reddit post that it's implied Isildur only asked them to reinforce one battle and that was the oath. Therefore once they routed the forces that besieged Gondor their oath was technically fulfilled. I dunno how true that is so take it with a grain of salt.

I have to say, I often wondered why Aragorn didn’t use them in the Pelanor Fields, but I can’t say I ever continued past wondering, and think it through. That makes a lot of sense.

Tolkien's Aragorn ; Understands the scope of using the Oathbreakers and releases them. GRRM's Aragorn : Keeps the Oathbreakers because the Lords of Gondor are livid that the King dares to return and interferes with their oppressing and sucking the peasants dry. Then he worries about how much he'll squeeze the Lords after he gave them a good kick in the head. Then worries about how he'll plan the logistics for the Orc genocide. Then gets stabbed in the eye by Faramir for looking at him funny and with Aragorn now a vegetable to be carried around on a litter while Faramir usurps the title of Steward of the King, blames it on "the elves" and has Legolas, Elladan and Elrohir horribly tortured and gruesomely executed. Gimli escapes, shaves his beard and gets ready to go into apocalyptic lawnmower mode and kill a bunch of main characters at the worst possible moment.

Aside from Aragorn’s word, it could be the dead mostly have power to instill fear in men. Legolas said he did not fear the ghosts of men. It could also be that Sauron would have greater power to command the dead, considering these dead once served Sauron. Though Sauron probably forgot about them

1. Aragorn is a man of honour, true to his word. He promised the Oathbreakers to release them from Isildur's curse once they fulfill their oath, and so he did. 2. Even in the days of the Last Alliance, they were afraid of challenging the might of the Dark Lord. I don't think they would follow Aragorn to face the full power of the Enemy.

Great video, Darth Gandalf! I would add one more reason why Aragorn could never (or would never) take the Oathbreakers to Minas Tirith, and it comes from Tolkien's own intentions when writing "The Return of the King". One of the purposes of the final battles of the War of the Ring was to show that Men were ready to take up the mantle of Good from Elves in the Fourth Age. It's the same reason why Peter Jackson's inclusion of Elves at the Battle at Helm's Deep is ridiculous at best. Men HAD to win those two battles (Helm's Deep and Pelennor) with minimal help from the other free peoples - aside from the obvious contributions of the hobbits. It's what sets up the Free Men to reign well in the Fourth Age. Personally, while I think the movies were well made and entertaining in their own right, the changes that Jackson made that detracted from Tolkien's intentions irritated the crap out of me, and I can't fully enjoy either of the last two movies because of it.

The problem with these questions is every one thinks things like the eagles and the oath breakers are tools to be wielded.

Another idea is that the smog clouds Sauron sent allowed the Oathbreakers to leave the mountains by blocking out the sun.

Actually taking Sauron worshipers to Sauron seems like a dangerous test. What is binding the strongest: fulfilling an oath, or the former god of undeads?

another possibility that isn't really mentioned here: Saurons reemergence had a strong effect on all evil things. who is to scythe oath breakers upon nearing the black gate would stay "good". since they already sided with Sauron in life

Technically, the Oathbreakers never fulfilled their oath. They would have fulfilled it only if they remained fighting of their own free will on Aragorn's side after Aragorn would have sayed to them that he releasing them from their services because they had fulfilled their oath.

Without watching any of the video, my answer: The men of the mountain can’t rest because of a curse that keeps them Mid-Earthbound until they fulfill their oaths and reclaim their honor. Isildor and his bloodline can remove this curse and grant them a peaceful final rest because they are bound in the thickest honor of all men. If Aragorn asked them to fight one battle at the High Cliffs after which they will be freed, only to turn around and suborn them for an additional, bigger battle, ehem, no…I mean suicide run on Mordor’s front door, that would be acting truly shamefully and without honor. Potentially, he’d be digging his own grave and ending his bloodline. The cursed could then have reason to attack him or perhaps the curse could even rebound upon him. Even if nothing terrible happens to him either physically or magically then and there, the rest of Man in Middle Earth looks to Gondor for security, motivation, inspiration and so on and see them as a perfect ideal for how men should behave. Betraying his own words could ruin him as king, make others not want to ride to battle with him anymore for fear he’ll do something similar to them. More than anything else, he’d be completely compromising himself if he does that and Aragorn is far to righteous and honorable to even consider braking his word as a man, let alone as the King of Man.

All I can think about while listening to LOTR video essays is how quickly Aragorn would have lost in Westeros

The Middle Earth had more than just these ghosts of oathbreakers. Like take example of whatever that was haunting at the Dead Marches. I also remember reading from books, that entrance to Minas Morgul was guarded by some demonic stuff. Its likely Mordor had tons of all kinds of ghost like entities or demons around too. So lets just say Mordor probably would be familiar with that kind of realm, making any kind of ghost stuff ineffective against them. Especially considering, how orcs scared their own overlords more than the enemy. Also, Sauron was once called "The Necromancer".

I think Sauron, a.k.a., the Necromancer, would have been able to seize control of the Oathbreakers had they shown up at Mordor. They had even been in his service back when they were still alive. Maybe even the Witch king could have handled them if he'd still been around. In any event, I think it is academic. Aragorn was always going to hold their paths fulfilled after Pelargir. I'm pretty surprised at the number of comments that say he had or should have had other motivations.

Because he barely got them to go to Helm's Deep. It required him promising to release them of their curse if they helped him defend Helm's Deep. Therefore, they ceased to exist as wraiths once that was achieved.

Just a thought but at the black gate Sauron might have usurped them. He was called the Necromancer, the dead kinda is in the job description.

I disagree with Tolkien's handling of the Oarhbreakers. Aragorn calls them to Erech and makes an agreement with them when their power and Aragorn's need for them are both unknowns. Successful kings don't generally limit their future options, such as by agreeing to release the Oathbreakers at Pelagir before victory is assured. I think it more likely Aragorn would have been vague, and only implied their release at Pelagir or Minas Tirith after Sauron's army was defeated. Beyond this, I agree. It makes sense for Aragorn not to rely on an undead army for longer than he has to, but he probably would make no promises up front. And the Oathbreakers have no reason to feel betrayed if Aragorn sets different conditions. One battle or two shouldn't make a big difference to their king, so long as Aragorn makes clear he's not asking for an assault on Mordor and siege of Barad Dur.

You forgot to mention one of Sauron’s powers was necromancy and telepathy. Sauron could have potentially telepathic communication to the Oath breakers and struck a new deal of raising them from the dead (possibly against their will) and could turn on Aragorn. I think that might be a chance Aragorn wasn’t willing to take

I always thought that if Aragorn said “Well you’re free to go, but if you’re willing to stick around for a couple more days and take out Mordor too, you would be remembered as heroes rather than oathbreakers” then the oathbreakers could potentially help at Mordor. They’ve been hanging around dick in hand for millenia, what's a few more days to them in exchange for a good legacy? As long as Aragorn agreed to release them regardless, I think that’d have been a good idea. Also, I highly doubt Eru Iluvatar would curse them to stay alive as ghosts until they fulfil their vow if they were physically incapable of fulfilling that vow. I think it’d be pretty absurd if they actually could do no harm, they’d be useless and trapped forever. The condition to end the curse would be a trick, and that’s not Iluvatar’s MO. I think the Oathbreakers truly are the most powerful army to ever exist in Middle Earth, they’re unkillable but are able to kill. I don’t think any army could kill a single one of them. I think that if given the chance to redeem themselves, they’d take it. However, there’s a decent chance they wouldn’t too - as they do seem to “live” by the idea that “the dead do not suffer the living to pass” so they really don’t give a shit about the living and their legends, but maybe given the opportunity, they’d stop talking smack and actually become decent people. It would be a 50/50 if he asked them to fight again, they might say no they might say yes, but either way the potential benefits are high and the potential detriment is minimal.

Great breakdown!

I mean Aragorn could have instead stipulated that the Oathbreakers had to help him throughout the rest of the conflict as opposed to one battle. Or at the very least stipulated that they needed to help when they reached the gates of Mordor. Assuming they had power there.

Also, if orcs are descended from corrupted elves, it is possible orcs retain elves lack of fear regarding the shades of men and wouldn’t be effected by the army of the dead.

A fan fiction about Aragorn the dark Lord of the undead would have been interesting.

great work, thanks!

Yes, the Curseth of Erech don´t have bodies as Nazguls have, but what about comparing them with the Specters of Barrow Downs? Their powers were quite impressive.

I disagree, Isildur only called the Oathbreakers to a single battle, which they did not show up for, and were cursed. Then after repaying the single battle, at Pelargir, their broken oath was fulfilled, game over! Otherwise Aragorn would have broken his oath and that a good King does not do.....

Cos if he had, he would have become an oathbreaker himself. At least, in spirit (no pun intended)

I love this part in the books because in any other story these Oathbreakers would be the evil force to defeat, but when fighting against an even greater threat, even death "allies" with Aragorn. ( death being one of the gifts of manking, denied to these warriors). The other angle shows that of all the races Sauron likes Men the best, for their capability for evil, for their resourcefulness. Maybe even Sauron is envious of Mens Gift. I always found strange that while he could create nazgul he could not simply ride to these men and try to put them on his side? I think even Nazgul have more freedom of thought and choice that people think despite the rings being obviously used to corrupt then. True Corruption only occurs if you allow it on yourself, its a choice to be evil. And of all the races Sauron respects men more because of this.

Definitely never knew most of that stuff about the ghosts, this will be a fine addition to my collection of obscure lotr lore

In the books when the company is passing the paths of the dead, didnt they find skeleton of Baldor son of King Brego who had both their legs broken and broken sword near them. Maybe you could argue the dead have power in where they were cursed but you could argue they can harm people too.

I always assumed they just wouldn't go and instead attack Aragorn based on the Ghost King's expression.

People say he’d be breaking his promise, but why didn’t he just promise them he’d free them after Mordor was defeated?

Their curse was for the DEFENSE of Gondor. To Take them any further would risk the geas backfiring onto Aragorn.

awesome vid really enjoyed it plus I always thought the army of the dead were cool both within the book and also in the film looking forward to the next vid 😀😀😀😀😀😀

I will hold the oath fulfilled, and ye shall have peace and depart forever. - Tolkien's Aragorn I hold your oath fulfilled. Go, be at peace. - Jackson's Aragorn I have altered the terms of our deal. Pray I do not alter it any further. -Bezos' Aragorn

Another reason it would not be a good idea to bring the ghost army to the black gates would be because it would defeat the purpose of that battle. The reason for the engagement was to draw Saurons forces out of mordor for Sam and frodo. But if the ghosts scared them back in that would put those two at risk.

Because Sauron is the most powerful Necromancer ever to exist in Middle Earth? Not a good place to take an army of undead.

I think there is a point here that maybe was overlooked. Now I'm no expert, but I do believe that the original betrayal concerned what the oath breakers pledged to do on behalf of Isildor. Maybe more importantly in this conversation, that includes what they didn't pledge. The oath breakers didn't pledge to fight side by side with gondor all across middle earth. In fact, the oath breakers weren't even part of the numanorian realm. They were a kingdom of their own adjacent to numanorian land. They pledged to fight on the side of the numanorians in their sphere of influence, and not to join forces with sauron. I can't recall exactly but I also think that some guarantee of autonomy was also offered. So in keeping with the original pledge, I don't think the oatbreakers were bound, or could be bound to act beyond what the original agreement was. By 1) fighting on behalf of the numanorians and 2) seeing saurons forces out of their spear of influence, I believe they had met their agreement,,,, finally.

There is a little passage about the Oat-breakers. In the past of Rohan, a drunk prince went up to the Oathbreakers and was found dead later, with broken legs. So, they can kill, or could kill, with or without fear. I don't see the problem with fear of keeping the Oathbreakers, because you just keep them in a separate group, away from the main force. The big problem is they obey only to Aragorn, so he must attend to them continuously in other ways they could act under their own volition or just consider themselves dismissed.

How can Aragorn demand them to fight another battle? He said should they fight for him, he would hold their oath fullfilled -- the ghosts had fought, and if Aragorn had not keep to his promise, he'd be an oathbreaker, dishonored king, liar and traitor. It's simply not how Tolkein see a right and just King would act, which Aragorn is meant to become. If middle earth is to survive, by the blood of the living, not the dead, so be it; for there's no other way but with honor and unbroken principles

Question: Why didn’t the eagles just take them to their final destination? Why didn’t they just take eagles from Rivendell? Tolkien : STFU

Sauron couldn’t just “take control” of the undead Dunlendings. Something like that would take time at the very least and probably require Sauron’s possession of the ring at the most. Their sudden appearance precluded Sauron’s having any interaction with them, and even if he managed to speak to them through the Witch King, I doubt they would have forsaken the (belated) fulfillment of their oath to the King.

I wonder why Aragorn didn't ask if the Oathbreakers might voluntarily serve him a bit longer than required. Maybe some portion would have volunteered.

What if Aragorn aked them to help him and they could decide if continue helping him or be released from the oath...

Aragorn called on them to fight at Helm's in Rohan, and their oath was fulfilled.

Also Sauron, known as the Necromancer, who knows may be he could take over the Oathbreakers and enslave them

Although they would have “come in handy in a tight spot” especially in Mordor, Aragorn was right to release them from their oaths. Honor and avoiding supernatural consequences.

My brother and I have been asking this for a lifeage of the Earth. There's NO reason these unkillable ghosts couldn't have washed the filth of Sauron away like a refreshing dam-broken flood

Since the oathbreakers were, in life, were allied to Mordor, whats to say that Sauron couldnt take control of them when so close to Mordor?

I was going to say Aragorn should have said I'll hold your oath fulfilled once you have driven every orc from Gondor, but after listening to your explanation, I changed my mind.

At that point the Breaking of the Seige of Minas Tirith had fulfilled the oath and anything more is a breach of the agreement. These men were already dead and just wanted rest and ordering them further than the fulfillment of their oaths would have made Aragorn the dishonorable one.

I suspect that Aragorn had t even thought of going to Mordor yet because it was considered suicide. Sauron and all of his evil minions and relations had been severely hampering the growth of humanity. Gondor and Rohan together were significantly outnumbered by orcs and there were mentions to indicate that humanity was mostly expanding eastward away from Mordor. It wasn’t until Sauron was killed and the elves and wizards left that the dark things faded leaving room for the time of Men.

Hm but why didnt aragorn command them to serve him in mordor too and then they will be realiesed?

The witch king has a ring of power and a sorcerer in his own right. Simple. That's the answer. If he can't even temporarily sway a cursed tainted ghost army- he can do nothing. Even in the film version they only attack after he is dead i think?

I see your point on Aragorn’s promise but the point still remains that did he need to make that promise or could he have said that he would release after the fall of Sauron

And, yes! The Oathbreakers *_were_* a special party trick.

Also Sauron is a necromancer. I would not bring an army of angry spirits that I have betrayed to face the most powerful undead weaver of the planet.
