|Heirloom Seal of the Realm|
In 221 BC, the Seal was created when Qin Shi Huang destroyed the remaining Warring States and united China under the Qin Dynasty. Heshibi was a famous piece of jade stone which previously belonged to the Zhao state. Passing into the hands of the new Emperor of China, he ordered it made into his Imperial seal. The words, "Having received the Mandate from Heaven, may (the emperor) lead a long and prosperous life." (??, ??) were written by Prime Minister Li Si, and carved onto the seal by Sun Shou.
The Seal was carved from jade because in ancient China, jade was symbolic of the inner beauty within humans. Many tombs and burials from ancient China contained decorative jade, including a jade burial suit unearthed in 1968 that belonged to a Han prince, Liu Sheng. During the Han dynasty, the Chinese associated jade with immortality to a point where some individuals attempted to drink jade in liquid form to gain eternal life. This association further complements the idea of the Mandate of Heaven and why the Seal was carved in jade, China's most valued material for thousands of years.
At the death of the second Emperor of Qin, his successor Ziying proffered the seal to the new emperor of the Han Dynasty, whereafter it was known as the "Han Heirloom Seal of the Realm". At the end of the Western Han Dynasty in 9 CE, Wang Mang, the usurper, forced the Han empress dowager to hand over the Seal. The empress dowager, in anger, threw the Seal on the ground, chipping one corner. Later, Wang Mang ordered the corner to be restored with gold.
This seal passed on even as dynasties rose and fell. It was seen as a legitimizing device, signalling the Mandate of Heaven. During turbulent periods, such as the Three Kingdoms period, the seal became the object of rivalry and armed conflict. Regimes which possessed the seal declared themselves, and are often historically regarded, as legitimate. At the end of the Han Dynasty in the 3rd century AD, General Sun Jian found the Imperial Seal when his forces occupied the evacuated Han imperial capital Luoyang, in the sequence of the campaign against Dong Zhuo, giving it to his chief, warlord Yuan Shu.
Yuan Shu then declared himself emperor under the short-lived Zhong dynasty in 197. This act angered the warlords Cao Cao and Liu Bei, leading to several crushing defeats by each army. The other warlords, even after being issued with an imperial decree, refused to help Cao Cao and Liu Bei in defeating Yuan Shu. When Yuan Shu was defeated in 199 by Liu Bei, the Seal came into the hands of Cao Cao, whose son Cao Pi proclaimed the Wei Dynasty as the legitimate successor state to Han, in 220, in response to the established states of Shu Han and Eastern Wu. The Seal remained in the hands of Wei Dynasty emperors until the last emperor Cao Huan was forced to abdicate in Sima Yan's favor, passing the Seal from Cao to Sima and establishing the Jin dynasty in 265.
The Seal was passed through the Cao Wei Dynasty, Jin Dynasty, Sixteen Kingdoms period, Southern and Northern Dynasties period, Sui Dynasty and Tang Dynasty, but was lost to history in the Five Dynasties and Ten Kingdoms period (907-960).
The fate of the seal during and after the Five Dynasties and Ten Kingdoms period is not known. Three theories exist as to when, and how, it was lost:
By the beginning of the Ming Dynasty, the Seal was known to be lost. Neither the Ming nor the Qing dynasties possessed it. This partly explains the Qing Emperors' obsession with creating numerous imperial seals - for the emperors' official use alone the Forbidden City in Beijing has a collection of 25 seals - in order to reduce the significance of the Heirloom Seal.
In the early 20th century, as the Qing Empire pursued reforms to modernise its system of government, a series of official seals were created for use on documents and instruments of the imperial government. Although square in shape following the traditional design, the seal dies themselves were made of wood, in imitation of western government precedents and, contrary to earlier Qing imperial seals which were bilingual (Chinese and Manchu), had only Chinese text. Four seal dies were carved: "The Seal of the Great Qing" (?), "The Seal of the Great Qing Emperor" (), "The Great Seal of the Great Qing Empire" (), and "The Seal of the Emperor of the Great Qing Empire" (). Of these, the Great Seal of the Great Qing Empire represented the official, modern "replacement" for the lost heirloom seal. The seal dies are in the collection of the Palace Museum in Beijing, and none show signs of use. After the fall of the Qing Empire in 1912, the Republic of China government likewise adopted a set of square-shaped official seals. The People's Republic of China initially adopted a similar square seal, but this fell out of use by 1954.
Several seals have since been claimed as the lost Heirloom Seal, but none have held up under scrutiny. In at least one case, the seal concerned was found to be a personal seal of an emperor, rather than the Heirloom Imperial Seal.
