History of China
–
Written records of the history of China can be found from as early as 1500 BC under the Shang dynasty. Ancient historical texts such as the Records of the Grand Historian and the Bamboo Annals describe a Xia dynasty, with thousands of years of continuous history, China is one of the worlds oldest civilizations, and is regarded as one of the cradles of civilization. Much of Chinese culture, literature and philosophy developed during the Zhou dynasty. This is one of multiple periods of failed statehood in Chinese history, between eras of multiple kingdoms and warlordism, Chinese dynasties have ruled parts or all of China, in some eras control stretched as far as Xinjiang and Tibet, as at present. In 221 BC Qin Shi Huang united the warring kingdoms and created for himself the title of emperor of the Qin dynasty. Successive dynasties developed bureaucratic systems that enabled the emperor to control vast territories directly, in the 21 centuries from 206 BC until AD1912, routine administrative tasks were handled by a special elite, the Scholar-officials. Young men were selected through difficult examinations and were well-versed in calligraphy and philosophy. What is now China was inhabited by Homo erectus more than a million years ago, recent study shows that the stone tools found at Xiaochangliang site are magnetostratigraphically dated to 1.36 million years ago. The archaeological site of Xihoudu in Shanxi Province is the earliest recorded use of fire by Homo erectus, the excavations at Yuanmou and later Lantian show early habitation. Perhaps the most famous specimen of Homo erectus found in China is the so-called Peking Man discovered in 1923–27, fossilised teeth of Homo sapiens dating to 125, 000–80,000 BC have been discovered in Fuyan Cave in Dao County in Hunan. The Neolithic age in China can be traced back to about 10,000 BC, Early evidence for proto-Chinese millet agriculture is radiocarbon-dated to about 7000 BC. The earliest evidence of cultivated rice, found by the Yangtze River, is carbon-dated to 8,000 years ago, farming gave rise to the Jiahu culture. At Damaidi in Ningxia,3,172 cliff carvings dating to 6000–5000 BC have been discovered, featuring 8,453 individual characters such as the sun, moon, stars, gods and these pictographs are reputed to be similar to the earliest characters confirmed to be written Chinese. Chinese proto-writing existed in Jiahu around 7000 BC, Dadiwan from 5800 BC to 5400 BC, Damaidi around 6000 BC, some scholars have suggested that Jiahu symbols were the earliest Chinese writing system. With agriculture came increased population, the ability to store and redistribute crops, Later, Yangshao culture was superseded by the Longshan culture, which was also centered on the Yellow River from about 3000 BC to 2000 BC. Bronze artifacts have been found at the Majiayao culture site, The Bronze Age is also represented at the Lower Xiajiadian culture site in northeast China. Sanxingdui located in what is now Sichuan province is believed to be the site of a ancient city. The site was first discovered in 1929 and then re-discovered in 1986, Chinese archaeologists have identified the Sanxingdui culture to be part of the ancient kingdom of Shu, linking the artifacts found at the site to its early legendary kings

Warring States period
–
The Warring States Period derives its name from the Record of the Warring States, a work compiled early in the Han dynasty. The political geography of the era was dominated by the Seven Warring States, namely, Qin, The State of Qin was in the far west, with its core in the Wei River Valley and Guanzhong. This geographical position offered protection from the states of the Central Plains, the Three Jins, Northeast of Qin, on the Shanxi plateau, were the three successor states of Jin. These were, Han, south, along the Yellow River, Zhao, the northernmost of the three. Qi, located in the east of China, centred on the Shandong Peninsula, described as east of Mount Tai, Chu, located in the south of China, with its core territory around the valleys of the Han River and, later, the Yangtze River. Yan, located in the northeast, centred on modern-day Beijing, late in the period Yan pushed northeast and began to occupy the Liaodong Peninsula Besides these seven major states, some minor states also survived into the period. Yue, On the southeast coast near Shanghai was the State of Yue, Sichuan, In the far southwest were the States of Ba and Shu. These were non-Zhou states that were conquered by Qin late in the period, in the Central Plains comprising much of modern-day Henan Province, many smaller city states survived as satellites of the larger states, though they were eventually to be absorbed as well. Zhongshan, Between the states of Zhao and Yan was the state of Zhongshan, the Spring and Autumn period was initiated by the eastward flight of the Zhou court. There is no one single incident or starting point for the Warring States era, some proposed starting points are as follows,481 BC, Proposed by Song-era historian Lü Zuqian, since it is the end of the Spring and Autumn Annals. 476–475 BC, The author, Sima Qian, of Records of the Grand Historian who chose the year of King Yuan of Zhou. 403 BC, The year when Han, Zhao and Wei were officially recognised as states by the Zhou court, author Sima Guang of Zizhi Tongjian tells us that the symbol of eroded Zhou authority should be taken as the start of the Warring States era. The Spring and Autumn period led to a few states gaining power at the expense of many others, during the Warring States period, many rulers claimed the Mandate of Heaven to justify their conquest of other states and spread their influence. Other major states also existed, such as Wu and Yue in the southeast, the last decades of the Spring and Autumn era were marked by increased stability, as the result of peace negotiations between Jin and Chu which established their respective spheres of influence. This situation ended with the partition of Jin, whereby the state was divided between the houses of Han, Zhao and Wei, and thus enabled the creation of the seven major warring states. This allowed other clans to gain fiefs and military authority, and decades of struggle led to the establishment of four major families. The Battle of Jinyang saw the allied Han, Zhao and Wei destroy the Zhi family, with this, they became the de facto rulers of most of Jins territory, though this situation would not be officially recognised until half a century later. The Jin division created a vacuum that enabled during the first 50 years expansion of Chu and Yue northward

Han dynasty
–
The Han dynasty was the second imperial dynasty of China, preceded by the Qin dynasty and succeeded by the Three Kingdoms period. Spanning over four centuries, the Han period is considered an age in Chinese history. To this day, Chinas majority ethnic group refers to itself as the Han people and it was founded by the rebel leader Liu Bang, known posthumously as Emperor Gaozu of Han, and briefly interrupted by the Xin dynasty of the former regent Wang Mang. This interregnum separates the Han dynasty into two periods, the Western Han or Former Han and the Eastern Han or Later Han, the emperor was at the pinnacle of Han society. He presided over the Han government but shared power with both the nobility and appointed ministers who came largely from the gentry class. The Han Empire was divided into areas controlled by the central government using an innovation inherited from the Qin known as commanderies. These kingdoms gradually lost all vestiges of their independence, particularly following the Rebellion of the Seven States, from the reign of Emperor Wu onward, the Chinese court officially sponsored Confucianism in education and court politics, synthesized with the cosmology of later scholars such as Dong Zhongshu. This policy endured until the fall of the Qing dynasty in 1911 AD, the Han dynasty was an age of economic prosperity and saw a significant growth of the money economy first established during the Zhou dynasty. The coinage issued by the government mint in 119 BC remained the standard coinage of China until the Tang dynasty. The period saw a number of limited institutional innovations, the Xiongnu, a nomadic steppe confederation, defeated the Han in 200 BC and forced the Han to submit as a de facto inferior partner, but continued their raids on the Han borders. Emperor Wu of Han launched several campaigns against them. The ultimate Han victory in these wars eventually forced the Xiongnu to accept vassal status as Han tributaries, the territories north of Hans borders were quickly overrun by the nomadic Xianbei confederation. Imperial authority was seriously challenged by large Daoist religious societies which instigated the Yellow Turban Rebellion. When Cao Pi, King of Wei, usurped the throne from Emperor Xian, following Liu Bangs victory in the Chu–Han Contention, the resulting Han dynasty was named after the Hanzhong fief. Chinas first imperial dynasty was the Qin dynasty, the Qin unified the Chinese Warring States by conquest, but their empire became unstable after the death of the first emperor Qin Shi Huangdi. Within four years, the authority had collapsed in the face of rebellion. Although Xiang Yu proved to be a commander, Liu Bang defeated him at Battle of Gaixia. Liu Bang assumed the title emperor at the urging of his followers and is known posthumously as Emperor Gaozu, Changan was chosen as the new capital of the reunified empire under Han

Eastern Wu
–
Wu, commonly known as Eastern Wu or Sun Wu, was one of the three major states that competed for supremacy over China in the Three Kingdoms period. It previously existed from 220–222 as a vassal kingdom nominally under Cao Wei, its rival state and it became an empire in 229 after its founding ruler, Sun Quan, declared himself Emperor. Its name was derived from the place it was based in — the Jiangnan region and it was called Eastern Wu because it occupied most of eastern China in the Three Kingdoms period, and Sun Wu because the family name of its rulers was Sun. During its existence, Wus capital was at Jianye, but at times it was also at Wuchang. Sun Ce broke off relations with Yuan Shu around 196-197 after the latter declared himself emperor — an act deemed as treason against Emperor Xian, the figurehead ruler of the Han dynasty. The warlord Cao Cao, who was the de facto head of government in the Han imperial court, Sun Ce was assassinated in the summer of 200 and was succeeded by his younger brother, Sun Quan. Sun Quan, like his brother, also paid nominal allegiance to Emperor Xian while maintaining autonomous rule over the Wu territories. In 208, Sun Quan allied with the warlord Liu Bei, Sun Quan and Liu Bei maintained their alliance against Cao Cao after the battle for the next ten years or so, despite having some territorial disputes over Jing Province. In 219, Sun Quan severed ties with Liu Bei when he sent his general Lü Meng to invade Lius territories in Jing Province, Guan Yu, who was defending Liu Beis assets in Jing Province, was captured and executed by Sun Quans forces. After that, the boundaries of Sun Quans domain extended from beyond the Jiangdong region to include the part of Jing Province. In 220, Cao Caos son and successor, Cao Pi, ended the Han dynasty by forcing Emperor Xian to abdicate in his favour, Sun Quan agreed to submit to Wei and was granted the title of a vassal king, King of Wu, by Cao Pi. A year later, Liu Bei declared himself emperor and founded the state of Shu Han, in 222, Liu Bei launched a military campaign against Sun Quan to take back Jing Province and avenge Guan Yu, leading to the Battle of Xiaoting. However, Liu Bei suffered a defeat at the hands of Sun Quans general Lu Xun and was forced to retreat to Baidicheng. Liu Beis successor, Liu Shan, and his regent, Zhuge Liang, made peace with Sun Quan later, Sun Quan declared independence from Wei in 222, but continued to rule as King of Wu until 229, when he declared himself Emperor of Wu. His legitimacy was recognised by Shu, Sun Quan ruled for over 30 years and his long reign resulted in stability in southern China. During his reign, Wu engaged Wei in numerous wars, including the battles of Ruxu, Shiting, however, Wu never managed to gain any territory north of the Yangtze River while Wei also never succeeded in conquering the lands south of the Yangtze. The conflict resulted in the emergence of two rivalling factions, each supporting either Sun He or Sun Ba, in Sun Quans imperial court. Sun Quan eventually deposed Sun He and forced Sun Ba to commit suicide, while Lu Xun, Sun Quan appointed his youngest son, Sun Liang, as the crown prince after the incident

Northern and Southern dynasties
–
The Northern and Southern dynasties was a period in the history of China that lasted from 420 to 589, following the tumultuous era of the Sixteen Kingdoms and the Wu Hu states. It is sometimes considered as the part of a longer period known as the Six Dynasties. Though an age of war and political chaos, it was also a time of flourishing arts and culture, advancement in technology. The period saw large-scale migration of Han Chinese to the south of the Yangtze. The period came to an end with the unification of all of China proper by Emperor Wen of the Sui Dynasty, during this period, the process of sinicization accelerated among the non-Chinese arrivals in the north and among the indigenous people in the south. Notable technological advances occurred during this period, the invention of the stirrup during the earlier Jin dynasty helped spur the development of heavy cavalry as a combat standard. Historians also note advances in medicine, astronomy, mathematics, intellectuals of the period include the mathematician and astronomer Zu Chongzhi. After the collapse of a united China under the Han dynasty in 220 due in part to the Yellow Turban. Of these, Cao Wei was the strongest, followed by Eastern Wu and Shu Han, after a 249 coup by Sima Yi, the Sima family essentially controlled Cao Wei and the conquest of Shu by Wei rapidly followed. Following a failed coup by the ruling Cao family against the Sima family, Sima Yan then founded the Jin Dynasty as Emperor Wu of Jin and the conquest of Wu by Jin occurred in 280, ending the Three Kingdoms period and reuniting China. The Jin dynasty was weakened after the War of the Eight Princes from 291-306. During the reigns of Emperor Huai and Emperor Min, the country was put into danger with the uprising of the northern non-Han people collectively known as the Five Barbarians. Invading non-Han armies almost destroyed the dynasty in the Disaster of Yongjia of 311, changan met a similar fate in 316. However, a scion of the house, Sima Rui, Prince of Langya, fled south of the Huai River to salvage what was left in order to sustain the empire. In the north, the Five Barbarians established numerous kingdoms, leading to the period being known as the Sixteen Kingdoms, eventually, the Northern Wei conquered the rest of the northern states in 386. The designation of specific households for military service in the system eventually led to a falling out in their social status. Faced with shortage of numbers, Jin generals were often sent on campaigns to capture non-Chinese people in the south in order to draft them into the military. The Northern dynasties began in 439 when the Northern Wei conquered the Northern Liang to unite northern China and it can be divided into three time periods, Northern Wei, Eastern and Western Weis, Northern Qi and Northern Zhou

Five Dynasties and Ten Kingdoms period
–
The Five Dynasties and Ten Kingdoms period, also called Five Dynasties, was an era of political upheaval in 10th-century imperial China. During this period, five states quickly succeeded one another in the Chinese Central Plain, while more than a dozen concurrent states were established elsewhere, mainly in south China. Traditionally, the era started with the fall of the Tang dynasty in 907 AD, many states were de facto independent kingdoms long before 907. After the Tang had collapsed, the kings who controlled the central plain crowned themselves as emperor, war between kingdoms occurred frequently to gain control of the central plain for legitimacy, and then over whole China. The last of the Five Dynasties and Ten Kingdoms states, Northern Han, was not vanquished until 979, the Five Dynasties were, Later Liang Later Tang Later Jin Later Han Later Zhou. The Ten Kingdoms were, Wu Wuyue Min Chu Southern Han Former Shu Later Shu Jingnan Southern Tang Northern Han and this era also led to the founding of the Liao dynasty in the north. Other regimes during this period were Yan, Qi, Zhao, Yiwu Jiedushi, Dingnan Jiedushi, Wuping Jiedushi, Qingyuan Jiedushi, Yin, Ganzhou, Shazhou, towards the end of the Tang, the imperial government granted increased powers to the jiedushi, the regional military governors. The Huang Chao Rebellion weakened the government, and by the early 10th century the jiedushi commanded de facto independence from its authority. Thus ensued the Five Dynasties and Ten Kingdoms period, although he was originally a member of Huang Chaos rebel army, he took on a crucial role in suppressing the Huang Chao Rebellion. For this function, he was awarded the Xuanwu Jiedushi title, within a few years, he had consolidated his power by destroying neighbours and forcing the move of the imperial capital to Luoyang, which was within his region of influence. In 904, he executed Emperor Zhaozong of Tang and made his 13-year-old son a subordinate ruler, three years later, he induced the boy emperor to abdicate in his favour. He then proclaimed emperor, thus beginning the Later Liang. During the final years of the Tang Dynasty, rival warlords declared independence in their governing provinces — not all of whom recognized the emperors authority, Li Cunxu and Liu Shouguang fiercely fought the regime forces to conquer northern China, Li Cunxu succeeded. He defeated Liu Shouguang in 915, and declared himself emperor in 923, within a few months, thus began the Shatuo Later Tang — the first in a long line of conquest dynasties. After reuniting much of northern China, Cunxu conquered Former Shu in 925, the Later Tang had a few years of relative calm, followed by unrest. In 934, Sichuan again asserted independence, in 936, Shi Jingtang, a Shatuo jiedushi from Taiyuan, was aided by the Liao dynasty in a rebellion against the Later Tang. In return for their aid, Shi Jingtang promised annual tribute, the rebellion succeeded, Shi Jingtang became emperor in this same year. Not long after the founding of the Later Jin, the Khitans regarded the emperor as a ruler for China proper

Song dynasty
–
The Song dynasty was an era of Chinese history that began in 960 and continued until 1279. It succeeded the Five Dynasties and Ten Kingdoms period, coincided with the Liao and Western Xia dynasties and it was the first government in world history to issue banknotes or true paper money nationally and the first Chinese government to establish a permanent standing navy. This dynasty also saw the first known use of gunpowder, as well as the first discernment of true north using a compass, the Song dynasty is divided into two distinct periods, Northern and Southern. During the Northern Song, the Song capital was in the city of Bianjing. The Southern Song refers to the period after the Song lost control of its half to the Jurchen Jin dynasty in the Jin–Song Wars. During this time, the Song court retreated south of the Yangtze, the Southern Song dynasty considerably bolstered its naval strength to defend its waters and land borders and to conduct maritime missions abroad. To repel the Jin, and later the Mongols, the Song developed revolutionary new military technology augmented by the use of gunpowder, in 1234, the Jin dynasty was conquered by the Mongols, who took control of northern China, maintaining uneasy relations with the Southern Song. Möngke Khan, the fourth Great Khan of the Mongol Empire and his younger brother Kublai Khan was proclaimed the new Great Khan, though his claim was only partially recognized by the Mongols in the west. In 1271, Kublai Khan was proclaimed the Emperor of China, after two decades of sporadic warfare, Kublai Khans armies conquered the Song dynasty in 1279. The Mongol invasion led to a reunification under the Yuan dynasty, the population of China doubled in size during the 10th and 11th centuries. The Northern Song census recorded a population of roughly 50 million, much like the Han and this data is found in the Standard Histories. However, it is estimated that the Northern Song had a population of some 100 million people and this dramatic increase of population fomented an economic revolution in pre-modern China. The expansion of the population, growth of cities, and the emergence of a national economy led to the withdrawal of the central government from direct involvement in economic affairs. The lower gentry assumed a role in grassroots administration and local affairs. Appointed officials in county and provincial centers relied upon the gentry for their services, sponsorship. Social life during the Song was vibrant, citizens gathered to view and trade precious artworks, the populace intermingled at public festivals and private clubs, and cities had lively entertainment quarters. The spread of literature and knowledge was enhanced by the expansion of woodblock printing. Technology, science, philosophy, mathematics, and engineering flourished over the course of the Song, although the institution of the civil service examinations had existed since the Sui dynasty, it became much more prominent in the Song period

Western Xia
–
The early capital was established at Ningxia. Therefore, its founders and history remained obscure until 20th-century research in the West, the Western Xia occupied the area round the Hexi Corridor, a stretch of the Silk Road, the most important trade route between North China and Central Asia. They made significant achievements in literature, art, music, and architecture, the region was known to the Tanguts and the Tibetans as Minyak. Western Xia is the translation of the states Chinese name. It is derived from its location on the side of the Yellow River, in contrast to the Liao and Jin dynasties on its east. The English term Tangut comes from the Mongolian name for the country, Tangghut, the Tuoba clan of the Xianbei of Tuyuhun founded the Western Xia. After the Tibetans destroyed the Tuyuhun in 670, its famous prince, Tuoba Chici, who controlled the Dangxiang Qiang submitted to the Tang, which bestowed upon him the imperial surname of Li. Towards the end of the Tang, the Tuoba brought troops to suppress the Huang Chao Rebellion on behalf of the Tang court and took control of the Xia State, or Xia Zhou, in northern Shaanxi in 881. After the Tang fell in 907, the Tuoba descendants formally declared resistance against the expanding Northern Song in 982, the foundation of Western Xia goes back to the year 982 under Li Jiqian. However, only in 1038 did the Tangut chieftain Li Yuanhao named himself emperor of Da Xia, the Song court recognised Li Yuanhao as governor but not as emperor, a title it regarded as exclusive to the Song emperor. After Jingzongs death, Yizong became the emperor at the age of two and his mother became the regent and during Yizongs reign, the Liao dynasty launched an invasion of Western Xia, causing Western Xia to submit to the Liao dynasty as a vassal state. After Yizongs death, Huizong was put under house arrest by his mother, the invasion was a failure, and Huizong took back power from his mother. After Chongzong became emperor, his grandmother became regent again and launched invasions of the Liao dynasty, again, both campaigns ended in defeat and Chongzong took direct control of Western Xia. He ended wars with both Liao and Song and focused on domestic reform, in 1115, the Jürchen Jin dynasty was established and the Liao emperor fled to Western Xia in 1123. Chongzong submitted to the Jin demand of the Liao emperor and Western Xia became a state of Jin. Immediately following Renzongs coronation, many natural disasters occurred, yet Renzong worked to stabilize the economy, the kingdom developed a Tangut script to write its own Tibeto-Burman language. Tibetans, Uyghurs, Han Chinese, and Tanguts served as officials in Western Xia, the practice of Tantric Buddhism in Western Xia led to the spread of some sexually related customs. After Renzongs death, Emperor Huanzong of Western Xia came into power, after Genghis Khan unified the northern grasslands of Mongolia, the Xianbei who resided near Mt. Yin self-proclaimed to be White Mongols and joined them

Yuan dynasty
–
The Yuan dynasty, officially the Great Yuan, was the empire or ruling dynasty of China established by Kublai Khan, leader of the Mongolian Borjigin clan. His realm was, by point, isolated from the other khanates and controlled most of present-day China and its surrounding areas. Some of the Mongolian Emperors of the Yuan mastered the Chinese language, while others used their native language. The Yuan dynasty is considered both a successor to the Mongol Empire and an imperial Chinese dynasty and it was the khanate ruled by the successors of Möngke Khan after the division of the Mongol Empire. In official Chinese histories, the Yuan dynasty bore the Mandate of Heaven, following the Song dynasty, the dynasty was established by Kublai Khan, yet he placed his grandfather Genghis Khan on the imperial records as the official founder of the dynasty as Taizu. In addition to Emperor of China, Kublai Khan also claimed the title of Great Khan, supreme over the other khanates, the Chagatai, the Golden Horde. As such, the Yuan was also referred to as the Empire of the Great Khan. However, while the claim of supremacy by the Yuan emperors was at times recognized by the khans, their subservience was nominal. In 1271, Kublai Khan imposed the name Great Yuan, establishing the Yuan dynasty, dà Yuán is from the clause 大哉乾元 in the Commentaries on the Classic of Changes section regarding Qián. The counterpart in Mongolian language was Dai Ön Ulus, also rendered as Ikh Yuan Üls or Yekhe Yuan Ulus, in Mongolian, Dai Ön is often used in conjunction with the Yeke Mongghul Ulus, resulting in Dai Ön Yeke Mongghul Ulus, meaning Great Mongol State. Nevertheless, both terms can refer to the khanate within the Mongol Empire directly ruled by Great Khans before the actual establishment of the Yuan dynasty by Kublai Khan in 1271. Genghis Khan united the Mongol and Turkic tribes of the steppes and he and his successors expanded the Mongol empire across Asia. Under the reign of Genghis third son, Ögedei Khan, the Mongols destroyed the weakened Jin dynasty in 1234, Ögedei offered his nephew Kublai a position in Xingzhou, Hebei. Kublai was unable to read Chinese but had several Han Chinese teachers attached to him since his early years by his mother Sorghaghtani and he sought the counsel of Chinese Buddhist and Confucian advisers. Möngke Khan succeeded Ögedeis son, Güyük, as Great Khan in 1251 and he granted his brother Kublai control over Mongol held territories in China. Kublai built schools for Confucian scholars, issued paper money, revived Chinese rituals and he adopted as his capital city Kaiping in Inner Mongolia, later renamed Shangdu. Many Han Chinese and Khitan defected to the Mongols to fight against the Jin, two Han Chinese leaders, Shi Tianze, Liu Heima, and the Khitan Xiao Zhala defected and commanded the 3 Tumens in the Mongol army. Liu Heima and Shi Tianze served Ogödei Khan, Liu Heima and Shi Tianxiang led armies against Western Xia for the Mongols
10.
Ming dynasty
–
The Ming dynasty was the ruling dynasty of China – then known as the Empire of the Great Ming – for 276 years following the collapse of the Mongol-led Yuan dynasty. The Ming, described by some as one of the greatest eras of orderly government, although the primary capital of Beijing fell in 1644 to a rebellion led by Li Zicheng, regimes loyal to the Ming throne – collectively called the Southern Ming – survived until 1683. He rewarded his supporters and employed them as a counterweight against the Confucian scholar-bureaucrats. One, Zheng He, led seven enormous voyages of exploration into the Indian Ocean as far as Arabia, the rise of new emperors and new factions diminished such extravagances, the capture of the Zhengtong Emperor during the 1449 Tumu Crisis ended them completely. The imperial navy was allowed to fall into disrepair while forced labor constructed the Liaodong palisade, haijin laws intended to protect the coasts from Japanese pirates instead turned many into smugglers and pirates themselves. The growth of Portuguese, Spanish, and Dutch trade created new demand for Chinese products and produced an influx of Japanese. This abundance of specie remonetized the Ming economy, whose money had suffered repeated hyperinflation and was no longer trusted. While traditional Confucians opposed such a prominent role for commerce and the newly rich it created, combined with crop failure, floods, and epidemic, the dynasty collapsed before the rebel leader Li Zicheng, who was defeated by the Manchu-led Eight Banner armies who founded the Qing dynasty. The Mongol-led Yuan dynasty ruled before the establishment of the Ming dynasty, consequently, agriculture and the economy were in shambles, and rebellion broke out among the hundreds of thousands of peasants called upon to work on repairing the dykes of the Yellow River. A number of Han Chinese groups revolted, including the Red Turbans in 1351, the Red Turbans were affiliated with the White Lotus, a Buddhist secret society. Zhu Yuanzhang was a peasant and Buddhist monk who joined the Red Turbans in 1352. In 1356, Zhus rebel force captured the city of Nanjing, with the Yuan dynasty crumbling, competing rebel groups began fighting for control of the country and thus the right to establish a new dynasty. In 1363, Zhu Yuanzhang eliminated his archrival and leader of the rebel Han faction, Chen Youliang, in the Battle of Lake Poyang, arguably the largest naval battle in history. Known for its ambitious use of ships, Zhus force of 200,000 Ming sailors were able to defeat a Han rebel force over triple their size, claimed to be 650. The victory destroyed the last opposing rebel faction, leaving Zhu Yuanzhang in uncontested control of the bountiful Yangtze River Valley, Zhu Yuanzhang took Hongwu, or Vastly Martial, as his era name. Hongwu made an effort to rebuild state infrastructure. He built a 48 km long wall around Nanjing, as well as new palaces, Hongwu organized a military system known as the weisuo, which was similar to the fubing system of the Tang dynasty. With a growing suspicion of his ministers and subjects, Hongwu established the Jinyiwei, some 100,000 people were executed in a series of purges during his rule
