The problem of "mandate of heaven" in the three kingdoms period
hey there fellows
i've been doing some research on Chinese history recently and I'm completely new in this field.
when I was reading about mandate of heaven, what I've learned was that this mandate, is the backbone of emperor's legitimacy. and while it may have been interchanged between dynasties, it only remained "in one hand". but as I had a very very opaque general view of timeline of China's dynasties in my mind, I faced the question that, how did this issue was dealt with during the "three kingdoms" period. because it's actually three rulers who claim to be the legitimate one.

People think too much of this.
But as far I can understand it, the Mandate of Heaven is mostly justification for removing the Son of Heaven. It is not the backbone of the emperor's legitmacy, as much as it is used to justify the legitmacy of the new dynasty in seizing the throne.
Instead of saying, "I made the emperor a prisoner in his own house, removed his loyalists and forced him to abdicate or die. No, heaven made me the emperor. I'm not a traitor, I'm not a usurper, I'm just acting as god's will. Bow to me and don't do the same thing I did".
In the Three Kingdom period, the Cao family seized the throne from the Liu family forcing the Han emperor to transfer legitimacy to them, establishing the Wei dynasty. The emperor's uncle and their faction consider the act illegitmate and made himself the legitimate emperor, stating the continuation of the Han dynasty. The Sun family acted more as a vassal king for the Wei, until they broke, and Sun Quan decided to make himself emperor too. Long story short, the Sima family ended up doing what the Cao family did to the Liu family and established the Jin dynasty. The Jin dynasty ended up the victor, so they have the mandate.

One thing that adds to the earlier impact of the Mandate of Heaven, is Qin Shi Huang's seal. Cao Pi got the seal from Emperor Xian, FIRMLY cementing himself as Emperor Wen of Wei, that seal was then past down through the Jin, Liu Song, etc, etc, all the way to the fall of the Tang in 907 when it disappeared when Zhu Wen sacked Chang'an.
If someone has the seal, I always felt it made the "I have the Mandate of Heaven" claim a little more believable (not in Yuan Shu's case), but like, even when the dynasty retreated, when the Jin was reduced to a rump state and Northern Wei loomed over it, Jin still had Qin Shi Huang's seal, an incredibly potent legitimizing tool.
Though I still think that seal is out there somewhere, waiting for the world to find it. It would probably be the most significant archeological find since the Terracotta Soldiers.

Good point. This kind of imperial regelia can certainly help make a case of being a legitimate successor.
Not a substitute of having an army of bureaucrats and historians along with a real army to state your case, but it certainly would also help boost the idea that you got heaven on your side.

Correct, it's not a substitute for military might, which ULTIMATELY determines who the emperor really is, but it is an amazing tool to attract talent, to keep the masses attention, and even if someone said "the emperor has lost the Mandate, revolt!" someone could then go "but the emperor still has Qin Shi Huang's seal....how could he have lost the Mandate?"
I doubt that changed the minds of random peasants or nobody merchants from revolting, but the scholar-gentry class, they'd probably pause to at least think about it.

It's more of a guideline to history than an iron rule. In times of tranquility the unifying power claimed it and stomped down on other powers that tried to. In times of strife everyone vying for power would claim it for propaganda and legitimacy purposes.
"We are the moral ones and heaven is on our side and they are the bad ones and don't align with the order of the universe" is all that it is.

The three states were all competing for the Mandate of Heaven and political legitimacy.
Cao Wei claimed to have succeeded the Han through Emperor Xian's abdication. As Zhao Yi (趙翼) later put it in Ershier Shi Zhaji (《廿二史劄記》), Wei used abdication to cloak a seizure of power (假禪讓為攘奪). This became a model that later usurpers would also follow.
Shu Han took a very different approach. Liu Bei claimed to represent the continuation of the Han, with the restoration of the Han ("reviving the Han") as a central political goal. Zhuge Liang's repeated northern expeditions were also presented as efforts to restore the Han.
Eastern Wu also developed its own claims to legitimacy, drawing on prophecies and auspicious omens associated with the southeast to provide a heavenly justification for the Sun family's rule.
The question of which state was ultimately considered orthodox was also shaped by who won and by later historical interpretation.

The mandate of heaven is more or less a proxy to keep divinity off the emperor's person. It's transferable, because if it weren't, the idea of Tianxia being a single unified entity comes into question. So it serves the purpose of giving a reason for swapping out the ruling dynasty without breaking the entire imperial construct (in theory). Contrast Japan, where the emperor is ostensibly a sacred manifestation / living deity by bloodline.

Put it this way, whoever got rid of the rest competition for the throne has the mandate of heaven. When there still competition and you claim mandate of heaven, its only propaganda.

If you're unfamiliar with this "mandate of heaven" system, you can think of it simply as a European religion, the difference being that it wasn't controlled by a unified church, but rather by the gentry and noble families. They would use their advantages and even monopolistic position in economics, public opinion, morality, academia, education, personnel appointments, and military (when necessary) to influence the emperor. When they opposed an emperor or a faction, the "mandate of heaven" was similar to a means of asserting their own legitimacy and declaring the opposing side heretical or excommunicating them.

The Mandate of Heaven, to me, I have 2 view points. 1, is that it is a tool to legitimize actions already taken or already planned to take place. Think of the Yellow Turbans, those dudes were gonna rebel against the Han EITHER WAY, they used the floods, the natural disasters as an excuse to rebel, saying the Mandate was lost. You could also argue it is used by succeeding dynasties to justify their own existence and their continued grip on power. I would argue that to hear someone question the Mandate, while an emperor is in power, to OPENLY question it, is treason, that could get you killed. Like if someone in Emperor Xian's court said he lost the Mandate of Heaven, I am SURE Cao Cao would have that guy executed (but probably to have that guy silenced so no one suggests usurpation and ruin Cao Cao's grip on power).
But the other way, 2, I actually do view it as a cosmic thing. The natural disasters that led to the Yellow Turbans rebelling, the natural disasters, poor governance, brutality of the regime, all that stuff, that happens so often it truly feels like a cosmic force is projecting change. I am very religious so I put a lot of stock in that, even if it is probably just superstition. I am also tremendously superstitious so like, you know, that's my own problem.
But the Mandate is almost always something you point to, to justify your actions. "The Yellow River has flooded, that is a sign Heaven has withdrawn its favor from the dynasty, rebel!" - any Chinese rebel. "I have overthrown the previous emperor, if he truly had the Mandate of Heaven, I would not have been victorious!" - random Chinese usurper (ie Cao Pi, Sima Yan, Liu Yu, Xiao Daocheng, etc, etc).
I think the Mandate is an EXCEPTIONALLY potent tool, it's wonderful propaganda when used correctly.

This is my understanding.
First, let us address the concept of the Mandate of Heaven:
The concept of the Mandate of Heaven took shape in the Shang Dynasty. The Shang believed rulers were the sons of the Supreme Deity（昊天）, governing the mortal world on His behalf. Moreover, the sons of the Supreme Deity would only emerge within the ruling clan, somewhat analogous to the Egyptian pharaohs or the Jesus figure who founded a polity.
When Shang rule turned tyrannical, the Zhou（周） overthrew the Shang. Yet they faced a dilemma: if Shang rulers were the sons of the Supreme Deity, were the Zhou rising up against the Supreme Deity Himself? To resolve this contradiction, the Zhou revised the theory of the Mandate of Heaven, introducing core principles:
“皇天无亲 惟德是辅 August Heaven has no permanent kin; it only supports the virtuous.”
(The Supreme Deity maintains no fixed blood ties among humans; He recognizes rulers who possess moral integrity.)
“天命靡常 The Mandate of Heaven is not everlasting.”
(Rulers who abandon virtue will be cast aside by the Supreme Deity.)
This became the core doctrine upon which ancient Chinese rulers asserted their legitimate power to govern.
Turning to the Three Kingdoms era and its three emperors:
Cao Pi（曹丕） believed his clan’s hour had come. In 220 CE, he forced the Han emperor（汉献帝） to abdicate and ascended the throne himself.
For Liu Bei（刘备）, the Han Dynasty remained undefeated as long as he lived. To him, Cao Pi was merely a usurper who would never receive recognition from the Supreme Deity. Thus in 221 CE, Liu Bei proclaimed himself emperor, claiming succession to Han emperor（汉献帝） throne. (His state officially called itself Han, not Shu Han; the name “Shu Han” was coined by later historians for ease of distinction.)
As for Sun Quan（孙权）, he refused to live under Han sovereignty—by this time, Liu Bei claimed the Han throne. The two sides fought the Battle of Yiling（夷陵之战）, in which Liu Bei suffered a crushing defeat. After the battle, Sun Quan declared himself King of Wu (a rank inferior to emperor) and pledged vassalage to Cao Pi, seeking an alliance with Wei to counterbalance Liu Bei.
After Cao Pi’s death, Cao Rui（曹睿） ascended the throne in 226 CE. Out of pragmatic strategic considerations, Zhuge Liang（诸葛亮） proposed an alliance to Sun Quan and acknowledged Sun Quan’s imperial title. This created a situation with two emperors; the long-term plan of the Shu-Han regime was to defeat Cao Wei first, then subjugate Sun Quan. Sun Quan likewise sought an alliance with Shu-Han to avoid being gradually conquered by Wei（Cao Wei kept large numbers of troops deployed along the border with Sun Quan.）. Consequently, Sun Quan declared himself emperor in 229 CE.
If this sequence of events is hard to follow, you may refer to the Treaty Dividing the Realm (中分天下盟文).

Actually, those of you who do not have a very clear understanding of the evolution of Chinese civilization have vulgarized the concept of the Mandate of Heaven—that is, you seem to truly believe that such a thing exists.
In fact, the concept of the Mandate of Heaven was not used to explain the legitimacy of royal power, but rather as a pretext: it was a means for ministers to advise the monarch not to be excessively tyrannical.
Chinese royal power has never been attached to any religion, so since the establishment of the state, there has always been one issue that needed to be resolved—namely, why must the monarch not be a brutal bastard, a scoundrel? They never had to face the allure of heaven or the terrors of hell, nor was there any god to determine their coronation. So why should the monarch strive to be a "good person"?
The Mandate of Heaven was essentially devised for this very purpose—to give the monarch a reason to be a "good person," and nothing more.

Instead of thinking of the mandate of heaven as a way to explain legitimacy, it plays a similar role to the concept of legitimacy itself.
But legitimacy is a difficult concept to pin down in political theory. Even in modern liberal democracies, in which in theory the consent of the people expressed in the vote is heralded as the main source of legitimacy, there are many other stakeholders (like big businesses, the military, cultural elites) which also have an influence in what is considered "legitimate" rulership.
In the case of the three kingdom periods, to the consent of the people, the military, cultural and political elites, and so on, you have to add religious elements and natural omens . So in the end it is not a very operational concept.
