Ancient China - Periods and Dynasties

Ancient China - Periods and Dynasties Chinese recorded history goes back more than 3000 years and if you add archaeological evidence (including Chinese pottery), another millennium and a half, to roughly 2500 B.C. The center of Chinese government moved repeatedly throughout this period, as China absorbed more of eastern Asia. This article looks at the conventional divisions of the history of China into eras and dynasties, starting with the earliest about which we have any information and continuing through to Communist China. Events of the past, if not forgotten, are teachings about the future. - Sima Qian, Chinese historian of the late second century B.C. The focus here is on the period of ancient Chinese history that begins with the advent of writing (as also for the Ancient Near East, Mesoamerica, and the Indus Valley) and ends with the period that corresponds best with a conventional date for the end of antiquity. Unfortunately, this date makes sense only in Europe: A.D. 476. That year is in the middle of the relevant Chinese period, the Southern Song and Northern Wei Dynasties, and is of no special significance for Chinese history. Neolithic First, according to historian Sima Qian, who chose to begin his Shiji (Records of the Historian) with the Yellow Emperor tale, Huang Di unified tribes along the Yellow River valley nearly 5,000 years ago. For these achievements, he is considered the founder of the Chinese nation and culture. Ever since 200BC, Chinese rulers, imperial and otherwise, have considered it politically convenient to sponsor an annual memorial ceremony in his honor.

Hunting, gathering, and agriculture were practiced during this period. Silk was also produced from mulberry leaf-fed silkworms. The pottery forms of the Neolithic period were painted and black, representing the two cultural groups, Yangshao (in the mountains of the north and west of China) and Lungshan (in the plains in eastern China), as well as utilitarian forms for daily use. Xia It had been thought that the Xia were a myth, but radiocarbon evidence for this Bronze Age people suggests that the period ran from 2100 to 1800 B.C. Bronze vessels found at Erlitou along the Yellow River, in northern central China, also attest to the reality of the Xia. The agrarian Xia were ancestors of the Shang. More on the Xia Reference: [URL www.nga.gov/exhibitions/chbro_bron.shtm] The Golden Age of Classical Archaeology Beginning of the Historical Era: Shang The truth about the Shang (c. 1700-1027 B.C.), who, like the Xia, had been considered mythical, came as a result of the discovery of the writing on oracle bones. It is traditionally believed that there were 30 kings and 7 capitals of the Shang. The ruler lived at the center of his capital. The Shang had bronze weapons and vessels, as well as earthenware. The Shang are credited with inventing Chinese writing because there are written records, notably the oracle bones. More on the Shang Dynasty Zhou The Zhou were originally semi-nomadic and had co-existed with the Shang. The dynasty began with Kings Wen (Ji Chang) and Zhou Wuwang (Ji Fa) who were considered ideal rulers, patrons of the arts, and descendants of the Yellow Emperor. The great philosophers flourished in the Zhou period. They banned human sacrifice. The Zhou developed a feudal-like system of allegiance and government that lasted as long as any other dynasty in the world, from about 1040-221 B.C. It was adaptable enough that it survived when barbarian invaders forced the Zhou to move their capital to the East. The Zhou period is sub-divided into: Western Zhou 1027-771 B.C.Eastern Zhou 770-221 B.C.770-476 B.C. Spring and Autumn period475-221 B.C. Warring States period During this period, iron tools were developed and population exploded. During the Warring States Period, only the Qin defeated their enemies. More on the Zhou Dynasty Qin The Qin Dynasty, which lasted from 221-206 B.C., was begun by the architect of the Great Wall of China, the first emperor, Qin Shihuangdi (aka Shi Huangdi or Shih Huang-ti) (r. 246/221 [start of the empire] -210 B.C.). The wall was built to repel nomadic invaders, the Xiongnu. Highways were also built. When he died, the emperor was buried in an enormous tomb with a terra cotta army for protection (alternatively, servants). During this period the feudal system was replaced by a strong central bureaucracy. The second emperor of the Qin was Qin Ershi Huangdi (Ying Huhai) who ruled from 209-207 B.C. The third emperor was the King of Qin (Ying Ziying) who ruled in 207 B.C. More on the Qin Dynasty Han The Han Dynasty, which was founded by Liu Bang (Han Gaozu), lasted for four centuries (206 B.C.- A.D. 8, 25-220). During this period, Confucianism became state doctrine. China had contact with the west via the Silk Road during this period. Under Emperor Han Wudi, the empire expanded into Asia. The dynasty is to divided into a Western Han and an Eastern Han because there was a split following the unsuccessful attempt by Wang Mang to reform the government. At the end of the Eastern Han, the empire was divided into three kingdoms by powerful warlords. More on the Han Dynasty Political disunity followed the collapse of the Han Dynasty. This was when the Chinese developed gunpowder for fireworks. Next: Three Kingdoms and Chin (Jin) Dynasty Source of Quote Archaeology and Chinese Historiography, by K. C. Chang.

The period from 220 to 589 is often called the period of 6 dynasties, which covers the Three Kingdoms, Chin Dynasty, and Southern and Northern Dynasties. At the start, the three leading economic centers of the Han Dynasty (the Three  kingdoms) tried to unify the land: The Cao-Wei Empire (220-265) from northern ChinaThe Shu-Han Empire (221-263) from the west, andThe Wu Empire (222-280) from the east, the most powerful of the three, based on a system of confederation of powerful families, which conquered the Shu in A.D. 263. During the period of the three kingdoms, tea was discovered, Buddhism spread, Buddhist pagodas were built, and porcelain was created. Chin Dynasty Also known as the  Jin Dynasty  (A.D. 265-420), the dynasty was started by Ssu-ma Yen (Sima Yan), who ruled as Emperor Wu Ti from A.D. 265-289. He reunified China in 280 by conquering the Wu kingdom. After reuniting, he ordered the disbanding of the armies, but this order was not uniformly obeyed. The Huns eventually defeated the  Chin,  but were never very strong. The Chin fled their capital, in Luoyang, ruling from 317-420, in  Jiankan  (modern Nanking), as the Eastern Chin (Dongjin). The earlier Chin period (265-316) is known as the Western Chin (Xijin). The culture of the Eastern Chin, remote from the Yellow River plains, developed a different culture from that of northern China. The Eastern Chin  were  the first of the Southern dynasties. Northern and Southern Dynasties Another period of disunity, the period of the Northern and Southern dynasties lasted from 317-589. The Northern Dynasties were The Northern Wei (386-533)The Eastern Wei (534-540)The Western Wei (535-557)The Northern Qi (550-577)The Northern Zhou (557-588) The Southern Dynasties were The Song (420-478)The Qi (479-501)The Liang (502-556)The Chen (557-588) The remaining dynasties are clearly medieval or modern and so are beyond the scope of this site: Classical Imperial ChinaSui 580-618 A.D. This short dynasty had two emperors Yang Chien (Emperor Wen Ti), an official of the northern Zhou, and his son Emperor Yang. They built canals and fortified the Great Wall on the northern frontier and began expensive military campaigns.Tang 618-907 A.D. The Tang composed a penal code and started a land distribution project to help the peasants, and expanded the empire into Iran, Manchuria, and Korea.

Sugar Produces Bitter Results for the Environment

Sugar Produces Bitter Results for the Environment Sugar is present in products we consume every day, yet we rarely give a second thought to how and where it is produced and what toll it may take on the environment. Sugar Production Damages the Environment According to the World Wildlife Fund (WWF), roughly 145 million tons of sugars are produced in 121 countries each year. And sugar production does indeed take its toll on surrounding soil, water and air, especially in threatened tropical ecosystems near the equator. A 2004 report by WWF, titled â€Å"Sugar and the Environment,† shows that sugar may be responsible for more biodiversity loss than any other crop, due to its destruction of habitat to make way for plantations, its intensive use of water for irrigation, its heavy use of agricultural chemicals, and the polluted wastewater that is routinely discharged in the sugar production process. Environmental Damage from Sugar Production Is Widespread One extreme example of environmental destruction by the sugar industry is the Great Barrier Reef off the coast of Australia. Waters around the reef suffer from large quantities of effluents, pesticides, and sediment from sugar farms, and the reef itself is threatened by the clearing of land, which has destroyed the wetlands that are an integral part of the reef’s ecology. Meanwhile, in Papua New Guinea, soil fertility has declined by about 40 percent over the last three decades in heavy sugar cane cultivation regions. And some of the world’s mightiest rivers- including the Niger in West Africa, the Zambezi in Southern Africa, the Indus River in Pakistan, and the Mekong River in Southeast Asia- have nearly dried up as a result of thirsty, water-intensive sugar production. Do Europe and the U.S. Produce Too Much Sugar? WWF blames Europe and, to a lesser extent, the United States, for over-producing sugar because of its profitability and therefore large contribution to the economy. WWF and other environmental groups are working on public education and legal campaigns to try to reform the international sugar trade. â€Å"The world has a growing appetite for sugar,† says Elizabeth Guttenstein of the World Wildlife Fund. â€Å"Industry, consumers and policy makers must work together to make sure that in the future sugar is produced in ways that least harm the environment.† Can Everglades Damage From Sugar Cane Farming be Reversed? Here in the United States the health of one of the country’s most unique ecosystems, Florida’s Everglades, is seriously compromised after decades of sugar cane farming. Tens of thousands of acres of the Everglades have been converted from teeming sub-tropical forest to lifeless marshland due to excessive fertilizer run-off and drainage for irrigation. A tenuous agreement between environmentalists and sugar producers under a â€Å"Comprehensive Everglades Restoration Plan† has ceded some sugar cane land back to nature and reduced water usage and fertilizer run-off. Only time will tell if these and other restoration efforts will help bring back Florida’s once teeming â€Å"river of grass.† Edited by Frederic Beaudry
