Sui dynasty

Foundation and Emperor Wen During the late Northern and Southern dynasties period, the Xianbei-led Northern Zhou conquered the Northern Qi in 577, reunifying northern China. By this time, Yang Jian, a Northern Zhou general who would later found the Sui dynasty, became the regent to the Northern Zhou court. but had intermarried with the Xianbei for generations. Emperor Wen emphasised Han cultural identity during his reign, The Chen dynasty could not withstand such an assault. By 589, Sui troops entered Jiankang (now Nanjing) and the last emperor of Chen surrendered. The city was razed to the ground, while Sui troops escorted Chen nobles back north, where the northern aristocrats became fascinated with everything the south had to provide culturally and intellectually. Although Emperor Wen was famous for bankrupting the state treasury with warfare and construction projects, he made many improvements to infrastructure during his early reign. He established granaries as sources of food and as a means to regulate market prices from the taxation of crops, much like the earlier Han dynasty. The large agricultural surplus supported rapid growth of population to a historical peak, which was only surpassed during the reign of Emperor Xuanzong of Tang more than a century later. The capital of Daxing (Chang'an, modern Xi'an), while situated in the militarily secure heartland of Guanzhong, was remote from the economic centres to the east and south of the empire. Emperor Wen initiated the construction of the Grand Canal, with completion of the first (and the shortest) route that directly linked Chang'an to the Yellow River. Later, Emperor Yang enormously enlarged the scale of the Grand Canal construction. Externally, the emerging Turkic Khaganate in the north posed a major threat to the newly founded dynasty. With Emperor Wen's diplomatic manoeuvre, the Khaganate split into Eastern and Western halves. Later the Great Wall was consolidated to further secure the northern territory. In Emperor Wen's late years, the first war with Goguryeo, ended with defeat. Nevertheless, the celebrated "Reign of Kaihuang" (era name of Emperor Wen) was considered by historians as one of the apexes in the two millennium imperial period of Chinese history. The Sui emperors were from the northwest military aristocracy, and they cited the Han clan as their ancestors. They emphasised their Han ancestry, and claimed descent from the Han official Yang Zhen. The New Book of Tang traces their patrilineal ancestry to the Zhou dynasty kings via the Dukes of Jin. The Li of Zhaojun and the Lu of Fanyang hailed from Shandong and were related to the Liu clan, which was also linked to the Hongnong Yangshi of and other clans of Guanlong. , a Sogdian merchant buried in Taiyuan in 592.

Information about these major political events in China were somehow filtered west and reached the Byzantine Empire, the continuation of the Roman Empire in the east. From Turkic peoples of Central Asia the Eastern Romans derived a new name for China after the older Sinae and Serica: Taugast (Old Turkic: Tabghach), during its Northern Wei (386–535) period. The 7th-century Byzantine historian Theophylact Simocatta wrote a generally accurate depiction of the reunification of China by Emperor Wen of the Sui dynasty, with the conquest of the rival Chen dynasty in southern China. Simocatta correctly placed these events within the reign period of Byzantine ruler Maurice. Simocatta also provided cursory information about the geography of China, its division by the Yangzi River and its capital Khubdan (from Old Turkic Khumdan, i.e. Chang'an) along with its customs and culture, deeming its people "idolatrous" but wise in governance. He noted that the ruler was named "Taisson", which he claimed meant "Son of God", perhaps Chinese Tianzi (Son of Heaven) or even the name of the contemporary ruler Emperor Taizong of Tang. Emperor Yang and re-conquest of Vietnam panel showing a Sui dynasty banquet with Sogdian whirl dance and music, 589 Emperor Yang of Sui (569–618) ascended the throne after his father's death, possibly by murder. He further extended the empire, but unlike his father, did not seek to gain support from the nomads. Instead, he restored Confucian education and the Confucian examination system for bureaucrats. By supporting educational reforms, he lost the support of the nomads. He also started many expensive construction projects such as the Grand Canal, and became embroiled in several costly wars. Between these policies, invasions into China from Turkic nomads, and his growing life of decadent luxury at the expense of the peasantry, he lost public support and was eventually assassinated by his own ministers. Both Emperors Yang and Wen sent military expeditions into Vietnam as Annam in northern Vietnam had been incorporated into the Chinese empire over 600 years earlier during the Han dynasty (202 BC – 220 AD). However the Kingdom of Champa in central Vietnam became a major counterpart to Chinese invasions to its north. According to Ebrey, Walthall, and Palais, these invasions became known as the Linyi-Champa Campaign (602–605). The Hanoi area formerly held by the Han and Jin dynasties was easily retaken from the Early Lý dynasty ruler Lý Phật Tử in 602. A few years later the Sui army pushed farther south and was attacked by troops on war elephants from Champa in southern Vietnam. The Sui army feigned retreat and dug pits to trap the elephants, lured the Champan troops to attack then used crossbows against the elephants causing them to turn around and trample their own soldiers. Although Sui troops were victorious many succumbed to disease as northern soldiers did not have immunity to tropical diseases such as malaria. One of the major work projects undertaken by the Sui was construction activities along the Great Wall of China; but this, along with other large projects, strained the economy and angered the resentful workforce employed. During the last few years of the Sui dynasty, the rebellion that rose against it took many of China's able-bodied men from rural farms and other occupations, which in turn damaged the agricultural base and the economy further. Men would deliberately break their limbs in order to avoid military conscription, calling the practice "propitious paws" and "fortunate feet." This practice was referred to as (). == Culture ==

player Although the Sui dynasty was relatively short-lived, in terms of culture, it represents a transition from the preceding ages, and many cultural developments which can be seen to be incipient during the Sui dynasty later were expanded and consolidated during the ensuing Tang dynasty, and later ages. This includes not only the major public works initiated, such as the Great Wall and the Great Canal, but also the political system developed by Sui, which was adopted by Tang with little initial change other than at the top of the political hierarchy. Other cultural developments of the Sui dynasty included religion and literature, particular examples being Buddhism and poetry. Rituals and sacrifices were conducted by the Sui. Taoism The Sui court pursued a pro-Taoist policy. The first reign of the dynasty saw the state promoting the Northern Louguan school of Taoism, while the second reign instead promoted the Southern Shangqing school of Taoism, possibly due to Emperor Yang's preference for Southern culture. Buddhism boddhisattva (Guanyin) Buddhism was popular during the Sixteen Kingdoms and Northern and Southern dynasties period that preceded the Sui dynasty, spreading from India through Kushan Afghanistan into China during the Late Han period. Buddhism gained prominence during the period when central political control was limited. Buddhism created a unifying cultural force that uplifted the people out of war and into the Sui dynasty. In many ways, Buddhism was responsible for the rebirth of culture in China under the Sui dynasty. While early Buddhist teachings were acquired from Sanskrit sutras, it was during the late Six dynasties and Sui dynasty that local Chinese schools of Buddhist thoughts started to flourish. Most notably, Zhiyi founded the Tiantai school, and completed the Great treatise on Concentration and Insight, within which he taught the principle of "Three Thousand Realms in a Single moment of Life" as the essence of Buddhist teaching outlined in the Lotus Sutra. Emperor Wen and his empress had converted to Buddhism to legitimise imperial authority over China and the conquest of Chen. The emperor presented himself as a Cakravartin king, a Buddhist monarch who would use military force to defend the Buddhist faith. In the year 601 AD, Emperor Wen had relics of the Buddha distributed to temples throughout China, with edicts that expressed his goals, "all the people within the Four Seas may, without exception, develop enlightenment and together cultivate fortunate karma, bringing it to pass that present existences will lead to happy future lives, that the sustained creation of good causation will carry us one and all up to wondrous enlightenment". Ultimately, this act was an imitation of Ashoka, a ruler of the ancient Maurya Empire in India. His most famous (as well as only surviving) work, the Explanation of the Mean (Zhongshuo, 中說) was compiled shortly after his death in 617. Poetry (600–673) Although poetry continued to be written, and certain poets rose in prominence while others disappeared from the landscape, the brief Sui dynasty, in terms of the development of Chinese poetry, lacks distinction, though it nonetheless represents a continuity between the Six Dynasties and the poetry of Tang. Sui dynasty poets include Yang Guang (580–618), who was the last Sui emperor (and a sort of poetry critic); and also, the Lady Hou, one of his consorts. == Rulers ==
