History of the Song dynasty
The Song dynasty of China was an imperial dynasty that ruled most of China proper and southern China from the middle of the 10th century into the last quarter of the 13th century. The dynasty was established by Emperor Taizu of Song with his usurpation of the throne of Later Zhou, ending the Five Dynasties and Ten Kingdoms period.
The Song is considered a high point of classical Chinese innovation in science and technology, an era that featured prominent intellectual figures such as Shen Kuo and Su Song and the revolutionary use of gunpowder weapons. However, it was also a period of political and military turmoil, with opposing and often aggressive political factions formed at court that impeded political, social, and economic progress. The frontier management policies of the Chancellor Wang Anshi exacerbated hostile conditions along the Chinese-Vietnamese border. This sparked a border war with Vietnam's Lý dynasty, which was fought to a mutual draw and concluded with a peace treaty in 1082. To the northwest the Song Empire frequently fought battles with the Tangut-led Western Xia dynasty, as well as the Khitan-led Liao dynasty to the north.
The Song Empire suffered a disastrous military defeat at the hands of the invading Jurchen-led Jin dynasty from the north in 1127 during the Jin–Song wars. Following the Jingkang Incident, the remnants of the Song court were forced to flee south from Kaifeng and establish a new capital at Hangzhou. The loss of northern territory and shifting of the capital marks the division of the dynasty into two distinct periods: the Northern Song and the Southern Song. The Southern Song developed a new navy to combat the Jin dynasty formed in the north. The Song dynasty was able to defeat further Jurchen invasions and even fought the Jin dynasty in an erstwhile alliance with the Mongols. However, the Mongol-led Yuan dynasty defeated the Song dynasty at the Battle of Yamen in 1279.
Founding of the Song
The Later Zhou was the last of the Five Dynasties that had controlled northern China after the fall of the Tang dynasty in 907. Zhao Kuangyin, later known as Emperor Taizu, usurped the throne and deposed the last Zhou ruler Guo Zongxun with the support of military commanders in 960, initiating the Song dynasty. Upon taking the throne, his first goal was the reunification of China after half a century of political division. This included the conquests of Nanping, Wu-Yue, Southern Han, Later Shu, and Southern Tang in the south as well as the Northern Han and the Sixteen Prefectures in the north. With capable military officers such as Pan Mei, Liu Tingrang, Cao Bin and Huyan Zan, the early Song military became the dominant force in China. Innovative military tactics, such as defending supply lines across floating pontoon bridges, led to success in battle such as the Song assault against the Southern Tang state while crossing the Yangzi River in 974. Using a mass of arrow fire from crossbowmen, Song forces were able to defeat the renowned war elephant corps of the Southern Han on 23 January 971, thus forcing the submission of Southern Han and terminating the first and last elephant corps that would make up a regular division within a Chinese army.File:Museum für Ostasiatische Kunst Dahlem Berlin Mai 2006 044.jpg|alt=A white teapot with an almost perfectly spherical body and a large, cylindrical cap in the center which is topped with a small crown shaped embellishment.

Consolidation in the south was completed in 978, with the conquest of Wu-Yue. Song military forces then turned north against the Northern Han, which fell to Song forces in 979. However, efforts to take the Sixteen Prefectures were unsuccessful and they were incorporated into the Liao state based in Manchuria to the immediate north instead. To the far northwest, the Tanguts had been in power over northern Shaanxi since 881, after the earlier Tang court appointed a Tangut chief as a military governor over the region, a seat that became hereditary. Although the Song state was evenly matched against the Liao dynasty, the Song gained significant military victories against the Western Xia.
After political consolidation through military conquest, Emperor Taizu held a famous banquet inviting many of the high-ranking military officers that had served him in Song's various conquests. As his military officers drank wine and feasted with Taizu, he spoke to them about the potential of a military coup against him like those of Five Dynasties era. His military officers protested against this notion, and insisted that none were as qualified as him to lead the country. The passage of this account in the Song Shi follows as such:
The emperor said, 'The life of man is short. Happiness is to have the wealth and means to enjoy life, and then to be able to leave the same prosperity to one's descendants. If you, my officers, will renounce your military authority, retire to the provinces, and choose there the best lands and the most delightful dwelling-places, there to pass the rest of your lives in pleasure and peace...would this not be better than to live a life of peril and uncertainty? So that no shadow of suspicion shall remain between prince and ministers, we will ally our families with marriages, and thus, ruler and subject linked in friendship and amity, we will enjoy tranquility'...The following day, the army commanders all offered their resignations, reporting maladies, and withdrew to the country districts, where the emperor, giving them splendid gifts, appointed them to high official positions.
Emperor Taizu developed an effective centralized bureaucracy staffed with civilian scholar-officials and regional military governors and their supporters were replaced by centrally appointed officials. This system of civilian rule led to a greater concentration of power in the central government headed by the emperor than had been possible during the previous dynasties. In the early 11th century, there were some 30,000 men who took the prefectural exams per year, which steadily increased to roughly 80,000 by the end of the century, and to 400,000 exam takers during the 13th century. Although new municipal governments were often established, the same number of prefectures and provinces were in existence as before the Song came to power. Thus although more people were taking exams, roughly the same number were being accepted into the government as in previous periods, making the civil service exams very competitive amongst aspiring students and scholars.
Emperor Taizu also found other ways to consolidate and strengthen his power, including updated map-making so that his central administration could easily discern how to handle affairs in the provinces. In 971, he ordered Lu Duosun to update and 're-write all the Tu Jing in the world'; a daunting task for one individual. Nonetheless, he travelled throughout the provinces to collect illustrative gazetteers and as much data as possible. With the aid of Song Zhun, the massive work was completed in 1010, with some 1566 chapters. The later Song Shi historical text stated :
Yuan Hsieh was Director-General of governmental grain stores. In pursuance of his schemes for the relief of famines he issued orders that each pao should prepare a map which would show the fields and mountains, the rivers and the roads in fullest detail. The maps of all the pao were joined together to make a map of the tu, and these in turn were joined with others to make a map of the hsiang and the hsien. If there was any trouble about the collection of taxes or the distribution of grain, or if the question of chasing robbers and bandits arose, the provincial officials could readily carry out their duties by the aid of the maps.
Taizu also displayed a strong interest in science and technology. He employed the Imperial Workshop to support such projects as Zhang Sixun's hydraulic-powered armillary sphere that used liquid mercury instead of water. Emperor Taizu was also quite open-minded in his affairs, especially with those perceived as foreigners: he appointed the Arab Muslim Ma Yize as the chief astronomer of the Song court. For receiving envoys from the Korean kingdom of Goryeo alone, the Song court had roughly 1,500 volumes written about the nuanced rules, regulations, and guidelines for their reception. The Song also sent envoys abroad, such as Wang Yande, who was sent as an official envoy to the Uyghur-Turkic city of Gaochang in 981, then under Kara-Khanid control. From the 2nd century onwards, ancient Chinese histories even record that embassies of the Roman Empire and Byzantine Empire arrived in China. As recorded in the History of Song and Wenxian Tongkao, the last known arrival of Byzantine envoys came in 1081, apparently sent by Michael VII Doukas to the court of Emperor Shenzong of Song. However, the History of Yuan records that a Byzantine man served as an astronomer and physician at the court of Kublai Khan during the subsequent Yuan dynasty, and in 1371 the Hongwu Emperor of the Ming dynasty sent an alleged Byzantine merchant to inform the Byzantine ruler of the founding of the new dynasty.
