The legitimacy of the royal family itself was also becoming an increasingly disputed issue within

5895-477: The ability to maintain their own armies, collect taxes, and pass their titles on hereditarily. This is commonly recognised as the beginning of the fall of Tang's central government.

6288-437: The ailing Tang was also challenged when natural disasters led many to believe that the Tang had lost their right to rule. In 873, a disastrous harvest shook the foundations of the empire; in some areas only half of all agricultural produce was gathered, and tens of thousands faced famine and starvation.

6943-534: The court fled Chang'an. While the heir apparent raised troops in Shanxi and Xuanzong fled to Sichuan , they called upon the help of the Uyghur Khaganate in 756. The Uyghur khan Moyanchur was greatly excited at this prospect, and married his own daughter to the Chinese diplomatic envoy once he arrived, receiving in turn a Chinese princess as his bride.

7074-500: The court, as the ruling house not only failed to govern the kingdom effectively, but was also affected by rivalry among its various branches and by generations of forced intermarriage with members of the Yuan imperial family, while King U 's biological mother being a known slave led to rumors contesting his descent from King Gongmin . Influential aristocrats, generals, and ministers struggled for royal favor and vied for domination of

According to one scholar, the Korean-Chinese border along the Yalu River is the longest unchanged international border in history, lasting for at least 1,000 years. The river is important for hydroelectric power, and one of the largest hydroelectric dams in Asia is in Sup'ung Dam , 106 metres (348 feet) high and over 850 metres (2,790 feet) long, located upstream from Sinuiju , North Korea . The dam has created an artificial lake over

7860-435: The effectiveness of the central government, the early 9th century is nonetheless viewed as a period of recovery for the Tang. The government's withdrawal from its role in managing the economy had the unintended effect of stimulating trade, as more markets with fewer bureaucratic restrictions were opened up.

7991-542: The establishment of the Joseon dynasty . The river has been the site of several battles because of its strategic location between Korea and China, including: The southern side of the river was heavily industrialized during the period of Japanese rule (1910–1945), and by 1945 almost 20% of Japan 's total industrial output originated in Korea .

The river has frequently been crossed by North Koreans fleeing to China since

8384-451: The foreign threats—namely Yi Sŏng-gye and his rival Ch'oe Yŏng .

After indirectly enforcing his grasp on the royal court through the puppet king, he proceeded to ally himself with Sinjin scholar-officials such as Chŏng To-jŏn and Cho Chun . One of

8646-611: The frontier every three years drained the treasury. By the late 7th century, the fubing troops began abandoning military service and the homes provided to them in the equal-field system. The supposed standard of 100 mu of land allotted to each family was in fact decreasing in size in places where population expanded and the wealthy bought up most of the land. Hard-pressed peasants and vagrants were then induced into military service with benefits of exemption from both taxation and corvée labour service, as well as provisions for farmland and dwellings for dependents who accompanied soldiers on

8777-544: The frontier. By 742, the total number of enlisted troops in the Tang armies had risen to about 500,000 men. In East Asia, Tang military campaigns were less successful elsewhere than in previous imperial Chinese dynasties.

As time passed, these military governors slowly phased out

9039-473: The government. General Yi swept his army from the Amnok River straight into the capital, defeated forces loyal to the royal family (led by General Ch'oe, whom he proceeded to eliminate), and forcibly dethroned King U in a de facto coup d'état , but did not ascend to the throne himself. Instead, he placed on the throne King U's eight-year-old son, Wang Ch'ang , and following a failed attempt to restore

9170-498: The imperial court. From Tang times until the end of the Qing dynasty in 1912, scholar-officials served as intermediaries between the people and the government. The potential of a widespread examination system was not fully realised until the succeeding Song dynasty, when the merit-driven scholar official largely shed his aristocratic habits and defined his social status through the examination system. The examination system, used only on

9301-407: The landed wealth and official positions, was largely destroyed or marginalised. During the last two decades of the Tang dynasty, the gradual collapse of central authority led to the rise of the rival military figures Li Keyong and Zhu Wen in northern China. Tang forces had defeated Huang's rebellion with the aid of allied Shatuo , a Turkic people of what is now Shanxi , led by Li Keyong. He

9432-487: The latter half of the 9th century; agrarian rebellions resulted in mass population loss and displacement, widespread poverty, and further government dysfunction that ultimately ended the dynasty in 907. The Tang capital at Chang'an (present-day Xi'an ) was the world's most populous city for much of the dynasty's existence. Two censuses of the 7th and 8th centuries estimated the empire's population at about 50 million people, which grew to an estimated 80 million by

9563-548: The many issues demonstrating the early strained relationship between Joseon and Ming was the debate of Taejo's genealogy, which began as early as 1394 and became a sort of diplomatic friction that lasted over 200 years. The Collected Regulations of the Great Ming erroneously recorded 'Yi Tan' (Taejo's personal name) as the son of Yi In-im , and that Yi Tan killed the last four kings of Goryeo , thereby establishing Ming's opinion of Taejo as an usurper first and foremost, from

9694-403: The money supply by upholding the use of private coinage, while his aristocratic and technocratic successor Li Linfu ( d.  753 ) favoured government monopoly over the issuance of coinage. After 737, most of Xuanzong's confidence rested in his long-standing chancellor Li Linfu , who championed a more aggressive foreign policy employing non-Chinese generals. This policy ultimately created

9825-403: The most to his father's rise to power, he harbored a profound hatred against two of Taejo's key allies, Chŏng To-jŏn and Nam Ŭn . Both sides were fully aware of the mutual animosity and felt constantly threatened. When it became clear that Yi Pang-wŏn was the most worthy successor, Chŏng To-jŏn used his influence to convince the king that the wisest choice would be the son that he loved most, not

9956-447: The most widely known events that occurred during this period was in 1392, when one of Yi Sŏng-gye's sons, Yi Pang-wŏn , organized a banquet for the renowned scholar and statesman Chŏng Mong-ju , who refused to be won over by General Yi despite their assorted correspondence in the form of archaic poems, and continued to be a faithful advocate for the old regime. Chŏng Mong-ju was revered throughout Goryeo, even by Yi Pang-wŏn himself, but in

10087-484: The new successor and abdicated. Thereafter, Taejo retired to the Hamhung Royal Villa and maintained distance with his fifth son for the rest of his life. Allegedly, Yi Pang-wŏn sent emissaries numerous times, and each time the former king executed them to express his firm decision not to meet his son again. This historical anecdote gave birth to the term Hamhung Chasa ( 함흥차사 ; 咸興差使 ), which means

10218-545: The northwest military aristocracy prevalent during the Sui dynasty . According to official Tang records, they were paternally descended from Laozi , the traditional founder of Taoism (whose personal name was Li Dan or Li Er), the Han dynasty general Li Guang , and Li Gao , the founder of the Han-ruled Western Liang kingdom. This family was known as the Longxi Li lineage, which also included

10349-647: The original Manchu word, but literally means "duck green", which was said to have been once the color of the river. The other theory is that the river was named after the combination of its two upper branches, which were called " 鴨 " ( Yā or Ap ) and " 綠 " ( Lù or R (or n ) ok )", respectively. Revised Romanization of Korean spelled it Amnokgang ( Korean pronunciation: [amnok.k͈aŋ] ; "Amnok River") and Revised Romanization of Hangeul spelled it Aprokgang ( Korean pronunciation: [amnok.k͈aŋ] ; "Aprok River"). From 2,500 metres (8,200 feet) above sea level on Paektu Mountain on

10480-517: The original forms after her death. Arguably the most important part of her legacy was diminishing the hegemony of the Northwestern aristocracy, allowing people from other clans and regions of China to become more represented in Chinese politics and government. There were many prominent women at court during and after Wu's reign, including Shangguan Wan'er (664–710), a poet, writer, and trusted official in charge of Wu's private office. In 706,

10611-478: The palace with a few followers and slew Empress Wei and her faction. He then installed his father Emperor Ruizong ( r.  710–712 ) on the throne. Just as Emperor Zhongzong was dominated by Empress Wei, so too was Ruizong dominated by Princess Taiping . This ended when Princess Taiping's coup failed in 712, and Emperor Ruizong abdicated to Emperor Xuanzong . The Tang reached its height during Emperor Xuanzong's 44-year reign, which has been characterized as

10742-399: The palace, killing Chŏng To-jŏn, his followers, and the two sons of the late Queen Sindeok. This incident became known as the 'First Strife of Princes' ( 제1차 왕자의 난 ). Aghast at the fact that his sons were willing to kill each other for the throne and psychologically exhausted by the death of his second wife, Taejo immediately named his second son, Yi Pang-gwa (posthumously King Jeongjong), as

10873-690: The peninsula and also by repelling the well-organized Japanese pirates in a series of successful engagements. In the wake of the rise of the Ming dynasty under Zhu Yuanzhang (the Hongwu Emperor ), the royal court in Goryeo split into two competing factions: the camp led by General Yi (supporting the Ming) and the one led by General Choe (supporting the Yuan). When a Ming messenger came to Goryeo in 1388 to demand

11004-496: The popular pipa . Tang scholars compiled a rich variety of historical literature , as well as encyclopaedias and geographical works. Notable innovations included the development of woodblock printing . Buddhism became a major influence in Chinese culture, with native Chinese sects gaining prominence. However, in the 840s, Emperor Wuzong enacted policies to suppress Buddhism , which subsequently declined in influence. The House of Li had ethnic Han origins, and it belonged to

11135-417: The population was tallied at 9 million households, about 50 million people, and this number did not increase in the census of 742. Patricia Ebrey writes that nonwithstanding census undercounting, China's population had not grown significantly since the earlier Han dynasty , which recorded 58 million people in 2 AD. Adshead disagrees, estimating about 75 million people by 750. In

11266-462: The position of Taishang Huang ('retired emperor'), and acted as regent to the puppet child-emperor Yang You . On the news of Emperor Yang's murder by General Yuwen Huaji on June 18, 618, Li Yuan declared himself emperor of the newly founded Tang dynasty. Emperor Gaozu ruled until 626, when he was forcefully deposed by his son Li Shimin , the Prince of Qin. Li Shimin had commanded troops since

11397-404: The practice of selling merchants the rights to buy monopoly salt, which they transported and sold in local markets. In 799, salt accounted for over half of the government's revenues. S. A. M. Adshead writes that this salt tax represents "the first time that an indirect tax, rather than tribute, levies on land or people, or profit from state enterprises such as mines, had been the primary resource of

11528-480: The previous dynasty, many regard him as a revolutionary and a decisive ruler who eliminated an inept, obsolete and crippled governing system to save the nation from foreign forces and conflicts. The resulting safeguarding of domestic security led the Koreans to rebuild and further discover their culture. In the midst of the rival Yuan and Ming dynasties, Joseon encouraged the development of national identity which

11659-606: The previous regime. He re-established amicable ties with Japan and improved relations with Ming China . The future King Taejo was born in Ssangseong Prefecture , on the frontiers of the Yuan dynasty . Taejo's father was Yi Cha-ch'un , an official of Korean ethnicity serving the Mongol -led Yuan. His mother, Lady Ch'oe , came from a family originally from Deungju (present-day Anbyŏn County , North Korea). In 1356,

11790-407: The prominence of civil officials drafted by exams, and became more autonomous from central authority. The rule of these powerful military governors lasted until 960, when a new civil order under the Song dynasty was established. The abandonment of the equal-field system also meant that people could buy and sell land freely; many poor fell into debt because of this and were forced to sell their land to

11921-400: The prominent Tang poet Li Bai . The Tang emperors were partially of Xianbei ancestry, as Emperor Gaozu of Tang 's mother Duchess Dugu was part-Xianbei. Apart from the traditional historiography, some modern historians have suggested the Tang imperial family might have modified its genealogy to conceal their Xianbei heritage. Emperor Gaozu (born Li Yuan) was the founder of the Tang. He

12052-445: The ranks. In October 1361, he killed Pak Ŭi, who rebelled against the government. In the same year, when the Red Turbans had invaded and seized Gaegyeong (present-day Kaesŏng ), he helped recapture the capital city with 3,000 men. In 1362, General Naghachu invaded Goryeo and Yi Sŏng-gye defeated him after being appointed as commander. General Yi had gained prestige during the late 1370s and early 1380s by pushing Mongol remains off

12183-479: The rebels, but they refused to leave until the Tang paid them an enormous sum of tribute in silk. Even Abbasid Arabs assisted the Tang in putting down the rebellion. A massacre of foreign Arab and Persian Muslim merchants by Tian Shengong happened during the An Lushan rebellion in the 760 Yangzhou massacre . The Tibetans took hold of the opportunity and raided many areas under Chinese control, and even after

12314-512: The release of enslaved Chinese prisoners who were captured during the transition from Sui to Tang from the northern frontier; this embassy succeeded in freeing 80,000 Chinese men and women who were then returned to China. While the Turks were settled in the Ordos region (former territory of the Xiongnu ), the Tang government took on the military policy of dominating the central steppe. As during

12445-509: The return of a significant portion of Goryeo's northern territory, Ch'oe Yŏng seized the opportunity and played upon the prevailing anti-Ming atmosphere to argue for the invasion of the Liaodong Peninsula (Goryeo claimed to be the successor of the ancient Korean kingdom of Goguryeo ; as such, restoring Manchuria as part of Korean territory was a tenet of its foreign policy throughout its history). A staunchly opposed Yi Sŏng-gye

12576-461: The river and the former capital of that kingdom was situated at what is now the medium-sized city of Ji'an along the Yalu, a site rich in Goguryeo-era relics. Wihwa Island on the river is historically famous as the place where, in 1388, General Yi Songgye (later Taejo of Joseon ) decided to turn back his army southward to Kaesong in the first of a series of revolts that eventually led to

12707-603: The river freezes during winter and can be crossed on foot. The depth of the Yalu River varies from some of the more shallow parts on the eastern side in Hyesan (1 meter (3 ft 3 in)) to the deeper parts of the river near the Yellow Sea (2.5 meters (8 ft 2 in)). The estuary is the site of the Amrok River estuary Important Bird Area , identified as such by BirdLife International . About 205 islands are on

12838-486: The river, despite repeated warnings by China not to, precipitated massive Chinese intervention from around Dandong . In the course of the conflict every bridge across the river except one was destroyed. The one remaining bridge was the Sino-Korean Friendship Bridge connecting Sinuiju , North Korea to Dandong , China. During the war the valley surrounding the western end of the river also became

12969-876: The same time the Tang faced threats on its western border when a large Chinese army was defeated by the Tibetans on the Dafei River in 670. By 676, the Tang army was expelled out of Korea by a unified Silla . Following a revolt of the Eastern Turks in 679, the Tang abandoned its Korean campaigns. Although the Tang had fought the Japanese, they still held cordial relations with Japan. There were numerous Imperial embassies to China from Japan, diplomatic missions that were not halted until 894 by Emperor Uda ( r.  887–897 ), upon persuasion by Sugawara no Michizane (845–903). The Japanese Emperor Tenmu ( r.  672–686 ) even established his conscripted army on that of

13100-521: The shift to a money economy boosted by the merchant class. Cities in the southern Jiangnan region such as Yangzhou , Suzhou , and Hangzhou prospered the most economically during the late Tang period. The government monopoly on salt production , weakened after the An Lushan rebellion, was placed under the Salt Commission , which became one of the most powerful state agencies, run by capable ministers chosen as specialists. The commission began

13231-470: The son that he felt was best for the kingdom. In 1392, the eighth son of King Taejo (his second son by Queen Sindeok ), Yi Pang-sŏk, was appointed as crown prince. After the sudden death of the queen in 1396 and while Taejo was still in mourning for his wife, Chŏng To-jŏn began conspiring to pre-emptively kill Yi Pang-wŏn and his brothers to secure his position in the royal court. In 1398, upon hearing of this plan, Yi Pang-wŏn immediately revolted and raided

13362-494: The south, to a point north of Kashmir bordering Persia in the west, to northern Korea in the north-east. Some of the kingdoms paying tribute to the Tang dynasty included Kashmir , Nepal, Khotan , Kucha , Kashgar , Silla , Champa , and kingdoms located in Amu Darya and Syr Darya valley. Turkic nomads addressed the Tang emperor as Tian Kehan . After the widespread Göktürk revolt of Shabolüe Khan ( d.  658 )

13493-560: The steppe nomads. Chinese foreign policy to the north and west now had to deal with Turkic nomads, who were becoming the most dominant ethnic group in Central Asia. To handle and avoid any threats posed by the Turks, the Sui government repaired fortifications and received their trade and tribute missions. They sent four royal princesses to form heqin marriage alliances with Turkic clan leaders, in 597, 599, 614, and 617. The Sui stirred trouble and conflict among ethnic groups against

13624-470: The throne in 1392 and abdicated six years later during a strife between his sons. He was honored as Emperor Go ( 고황제 ; 高皇帝 ) following the establishment of the Korean Empire . Taejo emphasized continuity over change. No new institutions were created, and no massive purges occurred during his reign. His new dynasty was largely dominated by the same ruling families and officials that had served

13755-701: The throne, he was deposed by Empress Wu in favour of his younger brother, Emperor Ruizong . This provoked a group of Tang princes to rebel in 684. Wu's armies suppressed them within two months. She proclaimed the Tianshou era of Wu Zhou on October 16, 690, and three days later demoted Emperor Ruizong to crown prince . He was also forced to give up his father's surname Li in favour of the Empress Wu. She then ruled as China's only empress regnant . A palace coup on February 20, 705, forced Empress Wu to yield her position on February 22. The next day, her son Zhongzong

13886-545: The time of the Hongwu Emperor when he repeatedly refused to acknowledge him as the new sovereign of the Korean Peninsula. The first mention of this error was in 1518 (about 9 years after the publication), and those who saw the publication made petitions towards Ming demanding for redress, among others left chanseong Yi Kye-maeng and minister of rites Nam Gon , who wrote Jonggye Byeonmu ( 종계변무 ; 宗系辨誣 ). It took until 1584 (after many Ming envoys had seen

14017-607: The various regions of the empire, it was recorded in 845 that bandits and river pirates in parties of 100 or more began plundering settlements along the Yangtze River with little resistance. In 858, massive floods along the Grand Canal inundated vast tracts of land and terrain of the North China Plain , which drowned tens of thousands of people in the process. The Chinese belief in the Mandate of Heaven granted to

14148-417: The way for the later overthrow of the Tang. Large groups of bandits in the size of small armies ravaged the countryside in the last years of the Tang. They smuggled illicit salt, ambushed merchants and convoys, and even besieged several walled cities. Amid the sacking of cities and murderous factional strife among eunuchs and officials, the top tier of aristocratic families, which had amassed a large fraction of

14279-488: The wealthy, which led to the exponential growth of large estates. With the breakdown of the land allocation system after 755, the central Chinese state barely interfered in agricultural management and acted merely as tax collector for roughly a millennium, save a few instances such as the Song's failed land nationalisation during the 13th-century war with the Mongols . With the central government collapsing in authority over

14410-475: The wife of Emperor Zhongzong of Tang, Empress Wei ( d.  710 ), persuaded her husband to staff government offices with his sister and her daughters, and in 709 requested that he grant women the right to bequeath hereditary privileges to their sons (which before was a male right only). Empress Wei eventually poisoned Zhongzong, whereupon she placed his fifteen-year-old son upon the throne in 710. Two weeks later, Li Longji (the later Emperor Xuanzong) entered

14541-445: Was a brief end to the hereditary jiedushi , as Xianzong appointed his own military officers and staffed the regional bureaucracies once again with civil officials. However, Xianzong's successors proved less capable and more interested in the leisure of hunting, feasting, and playing outdoor sports, allowing eunuchs to amass more power as drafted scholar-officials caused strife in the bureaucracy with factional parties. The eunuchs' power

14672-570: Was aided by the fiscal reforms of the 780s, including a government monopoly on the salt industry. He also had an effective and well-trained imperial army stationed at the capital led by his court eunuchs; this was the Army of Divine Strategy, numbering 240,000 in strength as recorded in 798. Between 806 and 819, Emperor Xianzong conducted seven major military campaigns to quell the rebellious provinces that had claimed autonomy from central authority, managing to subdue all but two of them. Under his reign, there

14803-517: Was almost totally diminished by 626, along with the 628 defeat of the Ordos warlord Liang Shidu ; after these internal conflicts, the Tang began an offensive against the Turks. In 630, Tang armies captured areas of the Ordos Desert, modern-day Inner Mongolia province, and southern Mongolia from the Turks. After this military victory, On June 11, 631, Emperor Taizong also sent envoys to the Xueyantuo bearing gold and silk in order to persuade

14934-483: Was also filled with incredible amounts of riches and resources to spare. When the Chinese prefectural government officials travelled to the capital in 643 to give the annual report of the affairs in their districts, Emperor Taizong discovered that many had no proper quarters to rest in and were renting rooms with merchants. Therefore, Emperor Taizong ordered the government agencies in charge of municipal construction to build every visiting official his own private mansion in

15065-447: Was also kept, although there were a few modifications. Although the central and local governments kept an enormous number of records about land property in order to assess taxes, it became common practice in the Tang for literate and affluent people to create their own private documents and signed contracts. These had their own signature and that of a witness and scribe in order to prove in court (if necessary) that their claim to property

15196-638: Was also known by the Korean name of Arinarye (아리나례강, 阿利那禮江). Ari , a word from Old Korean used to refer to the 'spirituality (신령성; 神靈性) of the sun'. The second component might be related to the Old Korean word for 'river, stream', nari (나리, 川理). Two other theories exist for the name Yalu: one theory is that the name derived from Yalu ula ( ᠶᠠᠯᡠ ᡠᠯᠠ ) in the Manchu language . The Manchu word yalu ( ᠶᠠᠯᡠ ) means "the boundary between two countries". In Mandarin Chinese, yālù phonetically approximates

15327-558: Was chosen to lead the invasion; however, at Wihwa Island on the Amnok River , he made a momentous decision known as the Wihwado Retreat ( 위화도 회군 ; 威化島 回軍 ; lit.  'Turning back the army from Wihwa Island'), which would alter the course of Korean history. Aware of the support he enjoyed from both high-ranking officials and the general populace, he decided to revolt and return to Gaegyeong to secure control of

15458-650: Was designed to draw the best talent into government. But perhaps an even greater consideration for the Tang rulers was to avoid imperial dependence on powerful aristocratic families and warlords by recruiting a body of career officials having no family or local power base. The Tang law code ensured equal division of inherited property among legitimate heirs, encouraging social mobility by preventing powerful families from becoming landed nobility through primogeniture . The competition system proved successful, as scholar-officials acquired status in their local communities while developing an esprit de corps that connected them to

15589-545: Was different when a servant or nephew killed a master or an uncle than when a master or uncle killed a servant or nephew. The Tang Code was largely retained by later codes such as the early Ming dynasty (1368–1644) code of 1397, yet there were several revisions in later times, such as improved property rights for women during the Song dynasty (960–1279). The Tang had three departments ( 省 ; shěng ), which were obliged to draft, review, and implement policies respectively. There were also six ministries ( 部 ; bù ) under

15720-595: Was ended when Zhu deposed Ai and took the throne for himself (known posthumously as Emperor Taizu of Later Liang). He established the Later Liang , which inaugurated the Five Dynasties and Ten Kingdoms period . A year later, Zhu had the deposed Emperor Ai poisoned to death. Zhu Wen's enemy Li Keyong died in 908, having never claimed the title of emperor out of loyalty to the Tang. His son Li Cunxu (Emperor Zhuangzong) inherited his title Prince of Jin along with his father's rivalry against Zhu. In 923, Li Cunxu declared

15851-421: Was established in 653; it was divided into 500 articles specifying different crimes and penalties ranging from ten blows with a light stick, one hundred blows with a heavy rod, exile, penal servitude, or execution. The legal code distinguished different levels of severity in meted punishments when different members of the social and political hierarchy committed the same crime. For example, the severity of punishment

15982-470: Was killed by his own son in 763. After 710, regional military governors called jiedushi gradually came to challenge the power of the central government. After the An Lushan rebellion, the autonomous power and authority accumulated by the jiedushi in Hebei went beyond the central government's control. After a series of rebellions between 781 and 784 in present-day Hebei, Henan , Shandong , and Hubei,

16113-491: Was legitimate. The prototype of this actually existed since the ancient Han dynasty, while contractual language became even more common and embedded into Chinese literary culture in later dynasties. The centre of the political power of the Tang was the capital city of Chang'an (modern Xi'an ), where the emperor maintained his large palace quarters and entertained political emissaries with music, sports, acrobats, poetry, paintings, and dramatic theatre performances . The capital

16244-465: Was made a jiedushi , and later Prince of Jin , bestowed with the imperial surname Li by the Tang court. Zhu Wen, originally a salt smuggler who served as a lieutenant under the rebel Huang Chao, surrendered to Tang forces. By helping to defeat Huang, he was renamed Zhu Quanzhong ("Zhu of Perfect Loyalty") and granted a rapid series of promotions to military governor of Xuanwu Circuit. In 901, from his power base of Kaifeng , Zhu Wen seized control of

16375-719: Was not challenged following the Ganlu Incident , where Emperor Wenzong ( r.  826–840 ) failed in his plot to have them overthrown; instead, Wenzong's allies were publicly executed in Chang'an's West Market on the eunuchs' command. Decades after the An Lushan rebellion, the Tang was able to muster enough power to launch offensive military campaigns, including its destruction of the Uyghur Khaganate in Mongolia from 840 to 847. The Tang managed to restore indirect control over former territories as far west as

16506-468: Was once threatened by the Mongols . However, some scholars, particularly in North Korea, view Taejo as a mere traitor to the old regime and bourgeois apostate, while paralleling him to General Ch'oe Yŏng , a military elite who conservatively served Goryeo to death. His diplomatic successes in securing Korea in the early modern period are notable. Consort(s) and their respective issue One of

16637-572: Was previously Duke of Tang and governor of Taiyuan , the capital of modern Shanxi , during the collapse of the Sui dynasty (581–618). Li had prestige and military experience, and was a first cousin of Emperor Yang of Sui (their mothers were both one of the Dugu sisters ). Li Yuan rose in rebellion in 617, along with his son and his equally militant daughter Princess Pingyang ( d.  623 ), who raised and commanded her own troops. In winter 617, Li Yuan occupied Chang'an , relegated Emperor Yang to

16768-533: Was put down at Issyk Kul in 657 by Su Dingfang (591–667), Emperor Gaozong established several protectorates governed by a Protectorate General or Grand Protectorate General, which extended the Chinese sphere of influence as far as Herat in Western Afghanistan. Protectorate Generals were given a great deal of autonomy to handle local crises without waiting for central admission. After Xuanzong's reign, jiedushi were given enormous power, including

16899-514: Was reported to have been favorably impressed by this embassy. Envoys from the Ryūkyū Kingdom were received in 1392, 1394 and 1397, as well as from Siam in 1393. In 1394, the new capital was established at Hanseong (present-day Seoul ). When the new dynasty was officially promulgated, the issue of which son would be the heir to the throne was brought up. Although Yi Pang-wŏn, Taejo's fifth son by his first wife Queen Sinui , had contributed

17030-554: Was restored to power; the Tang was formally restored on March 3. She died soon after. To legitimise her rule, she circulated a document known as the Great Cloud Sutra , which predicted that a reincarnation of the Maitreya Buddha would be a female monarch who would dispel illness, worry, and disaster from the world. She even introduced numerous revised written characters for the language, though they reverted to

17161-473: Was the improvement of relations with the Ming ; this had its origin in Taejo's refusal to attack their neighbor in response to raids from Chinese bandits. Shortly after his accession, he sent envoys to inform the court at Nanjing that a dynastic change had taken place. Envoys were also dispatched to Japan, seeking the re-establishment of amicable connections. The mission was successful, and Ashikaga Yoshimitsu
