Taxonomy (biology)
–
Taxonomy is the science of defining groups of biological organisms on the basis of shared characteristics and giving names to those groups. The exact definition of taxonomy varies from source to source, but the core of the remains, the conception, naming. There is some disagreement as to whether biological nomenclature is considered a part of taxonomy, the broadest meaning of taxonomy is used here. The word taxonomy was introduced in 1813 by Candolle, in his Théorie élémentaire de la botanique, the term alpha taxonomy is primarily used today to refer to the discipline of finding, describing, and naming taxa, particularly species. In earlier literature, the term had a different meaning, referring to morphological taxonomy, ideals can, it may be said, never be completely realized. They have, however, a value of acting as permanent stimulants. Some of us please ourselves by thinking we are now groping in a beta taxonomy, turrill thus explicitly excludes from alpha taxonomy various areas of study that he includes within taxonomy as a whole, such as ecology, physiology, genetics, and cytology. He further excludes phylogenetic reconstruction from alpha taxonomy, thus, Ernst Mayr in 1968 defined beta taxonomy as the classification of ranks higher than species. This activity is what the term denotes, it is also referred to as beta taxonomy. How species should be defined in a group of organisms gives rise to practical and theoretical problems that are referred to as the species problem. The scientific work of deciding how to define species has been called microtaxonomy, by extension, macrotaxonomy is the study of groups at higher taxonomic ranks, from subgenus and above only, than species. While some descriptions of taxonomic history attempt to date taxonomy to ancient civilizations, earlier works were primarily descriptive, and focused on plants that were useful in agriculture or medicine. There are a number of stages in scientific thinking. Early taxonomy was based on criteria, the so-called artificial systems. Later came systems based on a complete consideration of the characteristics of taxa, referred to as natural systems, such as those of de Jussieu, de Candolle and Bentham. The publication of Charles Darwins Origin of Species led to new ways of thinking about classification based on evolutionary relationships and this was the concept of phyletic systems, from 1883 onwards. This approach was typified by those of Eichler and Engler, the advent of molecular genetics and statistical methodology allowed the creation of the modern era of phylogenetic systems based on cladistics, rather than morphology alone. Taxonomy has been called the worlds oldest profession, and naming and classifying our surroundings has likely been taking place as long as mankind has been able to communicate

Plant
–
Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae. The term is generally limited to the green plants, which form an unranked clade Viridiplantae. This includes the plants, conifers and other gymnosperms, ferns, clubmosses, hornworts, liverworts, mosses and the green algae. Green plants have cell walls containing cellulose and obtain most of their energy from sunlight via photosynthesis by primary chloroplasts and their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic and have lost the ability to produce amounts of chlorophyll or to photosynthesize. Plants are characterized by sexual reproduction and alternation of generations, although reproduction is also common. There are about 300–315 thousand species of plants, of which the great majority, green plants provide most of the worlds molecular oxygen and are the basis of most of Earths ecologies, especially on land. Plants that produce grains, fruits and vegetables form humankinds basic foodstuffs, Plants play many roles in culture. They are used as ornaments and, until recently and in variety, they have served as the source of most medicines. The scientific study of plants is known as botany, a branch of biology, Plants are one of the two groups into which all living things were traditionally divided, the other is animals. The division goes back at least as far as Aristotle, who distinguished between plants, which generally do not move, and animals, which often are mobile to catch their food. Much later, when Linnaeus created the basis of the system of scientific classification. Since then, it has become clear that the plant kingdom as originally defined included several unrelated groups, however, these organisms are still often considered plants, particularly in popular contexts. When the name Plantae or plant is applied to a group of organisms or taxon. The evolutionary history of plants is not yet settled. Those which have been called plants are in bold, the way in which the groups of green algae are combined and named varies considerably between authors. Algae comprise several different groups of organisms which produce energy through photosynthesis, most conspicuous among the algae are the seaweeds, multicellular algae that may roughly resemble land plants, but are classified among the brown, red and green algae. Each of these groups also includes various microscopic and single-celled organisms

Flowering plant
–
The flowering plants, also known as Angiospermae or Magnoliophyta, are the most diverse group of land plants, with 416 families, approx. 13,164 known genera and a total of c.295,383 known species, etymologically, angiosperm means a plant that produces seeds within an enclosure, in other words, a fruiting plant. The term angiosperm comes from the Greek composite word meaning enclosed seeds, the ancestors of flowering plants diverged from gymnosperms in the Triassic Period, during the range 245 to 202 million years ago, and the first flowering plants are known from 160 mya. They diversified extensively during the Lower Cretaceous, became widespread by 120 mya, angiosperms differ from other seed plants in several ways, described in the table. These distinguishing characteristics taken together have made the angiosperms the most diverse and numerous land plants, the amount and complexity of tissue-formation in flowering plants exceeds that of gymnosperms. The vascular bundles of the stem are arranged such that the xylem and phloem form concentric rings, in the dicotyledons, the bundles in the very young stem are arranged in an open ring, separating a central pith from an outer cortex. In each bundle, separating the xylem and phloem, is a layer of meristem or active formative tissue known as cambium, the soft phloem becomes crushed, but the hard wood persists and forms the bulk of the stem and branches of the woody perennial. Among the monocotyledons, the bundles are more numerous in the stem and are scattered through the ground tissue. They contain no cambium and once formed the stem increases in diameter only in exceptional cases, the characteristic feature of angiosperms is the flower. Flowers show remarkable variation in form and elaboration, and provide the most trustworthy external characteristics for establishing relationships among angiosperm species, the function of the flower is to ensure fertilization of the ovule and development of fruit containing seeds. The floral apparatus may arise terminally on a shoot or from the axil of a leaf, occasionally, as in violets, a flower arises singly in the axil of an ordinary foliage-leaf. There are two kinds of cells produced by flowers. Microspores, which divide to become pollen grains, are the male cells and are borne in the stamens. The female cells called megaspores, which divide to become the egg cell, are contained in the ovule. The flower may consist only of parts, as in willow. Usually, other structures are present and serve to protect the sporophylls, the individual members of these surrounding structures are known as sepals and petals. The outer series is usually green and leaf-like, and functions to protect the rest of the flower, the inner series is, in general, white or brightly colored, and is more delicate in structure. It functions to attract insect or bird pollinators, attraction is effected by color, scent, and nectar, which may be secreted in some part of the flower

Medicinal plants
–
Medicinal plants, medicinal herbs, or simply herbs have been identified and used from prehistoric times. Plants make many chemical compounds for biological functions, including defence against insects, fungi, over 12,000 active compounds are known to science. These chemicals work on the body in exactly the same way as pharmaceutical drugs. However, since a plant may contain many substances, the effects of taking a plant as medicine can be complex. The earliest historical records of herbs are found from the Sumerian civilisation, drug research makes use of ethnobotany to search for pharmacologically active substances in nature, and has in this way discovered hundreds of useful compounds. These include the common drugs aspirin, digoxin, quinine, the compounds found in plants are of many kinds, but most are in four major biochemical classes, the alkaloids, glycosides, polyphenols, and terpenes. Medicinal plants are used to treat disease in non-industrialized societies. The annual global export value of plants in 2012 was over US$2.2 billion. Plants, including many now used as herbs and spices, have been used as medicines from prehistoric times. Spices have been used partly to counter food spoilage bacteria, especially in hot climates, angiosperms were the original source of most plant medicines. Human settlements are surrounded by weeds useful as medicines, such as nettle, dandelion. Humans were not alone in using herbs as medicines, some such as non-human primates, monarch butterflies. Plant samples from prehistoric sites are among the lines of evidence that Paleolithic peoples had knowledge of herbal medicine. The mushroom was used to treat whipworm. In ancient Sumeria, hundreds of plants including myrrh and opium are listed on clay tablets. The ancient Egyptian Ebers Papyrus lists over 800 plant medicines such as aloe, cannabis, castor bean, garlic, juniper, the Chinese pharmacopoeia, the Shennong Ben Cao Jing records plant medicines such as chaulmoogra for leprosy, ephedra, and hemp. This was expanded in the Tang Dynasty Yaoxing Lun, in the fourth century BC, Aristotles pupil Theophrastus wrote the first systematic botany text, Historia plantarum. In the Early Middle Ages, Benedictine monasteries preserved medical knowledge in Europe, translating and copying classical texts, hildegard of Bingen wrote Causae et Curae on medicine

China
–
China, officially the Peoples Republic of China, is a unitary sovereign state in East Asia and the worlds most populous country, with a population of over 1.381 billion. The state is governed by the Communist Party of China and its capital is Beijing, the countrys major urban areas include Shanghai, Guangzhou, Beijing, Chongqing, Shenzhen, Tianjin and Hong Kong. China is a power and a major regional power within Asia. Chinas landscape is vast and diverse, ranging from forest steppes, the Himalaya, Karakoram, Pamir and Tian Shan mountain ranges separate China from much of South and Central Asia. The Yangtze and Yellow Rivers, the third and sixth longest in the world, respectively, Chinas coastline along the Pacific Ocean is 14,500 kilometers long and is bounded by the Bohai, Yellow, East China and South China seas. China emerged as one of the worlds earliest civilizations in the basin of the Yellow River in the North China Plain. For millennia, Chinas political system was based on hereditary monarchies known as dynasties, in 1912, the Republic of China replaced the last dynasty and ruled the Chinese mainland until 1949, when it was defeated by the communist Peoples Liberation Army in the Chinese Civil War. The Communist Party established the Peoples Republic of China in Beijing on 1 October 1949, both the ROC and PRC continue to claim to be the legitimate government of all China, though the latter has more recognition in the world and controls more territory. China had the largest economy in the world for much of the last two years, during which it has seen cycles of prosperity and decline. Since the introduction of reforms in 1978, China has become one of the worlds fastest-growing major economies. As of 2016, it is the worlds second-largest economy by nominal GDP, China is also the worlds largest exporter and second-largest importer of goods. China is a nuclear weapons state and has the worlds largest standing army. The PRC is a member of the United Nations, as it replaced the ROC as a permanent member of the U. N. Security Council in 1971. China is also a member of numerous formal and informal multilateral organizations, including the WTO, APEC, BRICS, the Shanghai Cooperation Organization, the BCIM, the English name China is first attested in Richard Edens 1555 translation of the 1516 journal of the Portuguese explorer Duarte Barbosa. The demonym, that is, the name for the people, Portuguese China is thought to derive from Persian Chīn, and perhaps ultimately from Sanskrit Cīna. Cīna was first used in early Hindu scripture, including the Mahābhārata, there are, however, other suggestions for the derivation of China. The official name of the state is the Peoples Republic of China. The shorter form is China Zhōngguó, from zhōng and guó and it was then applied to the area around Luoyi during the Eastern Zhou and then to Chinas Central Plain before being used as an occasional synonym for the state under the Qing

Actinidia deliciosa
–
Actinidia deliciosa, fuzzy kiwifruit or mangüeyo is a fruiting vine native to southern China, the fruit of which has been declared the national fruit of that country. Other species of Actinidia are also found in China and range east to Japan and this species grows naturally at altitudes between 600 and 2,000 m. Actinidia deliciosa is a vigorous, woody, twining vine or climbing shrub reaching 9 m, the black-lyre leafroller moth is one of the few commercially significant pests of this plant. Its leaves are alternate, long-petioled, deciduous, oval to circular, cordate at the base. Young leaves are coated with red hairs, mature leaves are dark-green and hairless on the upper surface, male and female flowers appear on different plants, and both sexes have to be planted in close proximity for fruit set. Bees are normally used by commercial orchards, although the more labour-intensive hand pollination is sometimes employed, male flowers are gathered and processed to extract their pollen. This is then sprayed back on to the female flowers, the oblong fruits are up to 6.25 cm long. The russet-brown skin of the fruits is densely covered with short, stiff, the flesh is firm until fully ripened, it is glistening, juicy and luscious. The color of the flesh is bright-green, or sometimes yellow, brownish or off-white, except for the white, succulent center from which many fine. The flavor is subacid to quite acid, the flavor is suggested to be similar to that of the gooseberry or strawberry. The two botanical varieties are, Actinidia deliciosa var. chlorocarpa Actinidia deliciosa var. deliciosa Zhong hua, jing li, ruan zao, abbott, Allison, Bruno, Hayward, Monty, and Greensill are the most significant cultivars in New Zealand. In 1847, specimens of the plant were collected by the agent for the Royal Horticultural Society, the seeds were planted in 1906 by a Wanganui nurseryman, Alexander Allison, with the vines first fruiting in 1910. People who tasted the fruit thought it had a flavour, so began to call it the Chinese gooseberry. The familiar cultivar Actinidia deliciosa Hayward was developed by Hayward Wright in Avondale and this is the most widely grown cultivar in the world. Chinese gooseberry was initially grown in gardens, but commercial planting began in the 1940s. In 1959, Turners and Growers named it kiwifruit, after New Zealands national bird, as of 2006, Italy was the leading producer of kiwifruit in the world, followed by New Zealand, Chile, France, Greece, Japan, and the United States. Kiwifruit is still produced in China, but China has never made it to the top 10 list of kiwifruit-producing countries, in China, it is grown mainly in the mountainous area upstream of the Yangtze River. It is also grown in areas of China, including Sichuan

Kiwifruit
–
Kiwifruit or Chinese gooseberry is the name given to the edible berries of several species of woody vines in the genus Actinidia. The most common group of kiwifruit is oval, about the size of a large hens egg. It has a fibrous, dull greenish-brown skin and bright green or golden flesh with rows of tiny, black, the fruit has a soft texture and a sweet but unique flavor. It is a crop in several countries, such as Italy, New Zealand, Chile, Greece. Early varieties were described in a 1904 nurserymans catalogue as having. edible fruits the size of walnuts, as per Indian language Hindi Kiwifruit is termed as Lalit. In 1962, New Zealand growers began calling it kiwifruit when exporting, the word kiwifruit and shortened kiwi has been used since around 1966 when the fruit was first imported from New Zealand to the United States. Kiwifruit has since become a name for all commercially grown fruit from the genus Actinidia. In New Zealand, the word kiwi is seldom used to refer to the fruit. Kiwifruit is native to north-central and eastern China, cultivation of the fuzzy kiwifruit spread from China in the early 20th century to New Zealand, where the first commercial plantings occurred. Although kiwifruit is a fruit of China, until recently, China was not a major producing country of kiwifruit. The fruit became popular with American servicemen stationed in New Zealand during World War II and later exported to California using the names Chinese gooseberry and melonette. In 1962, New Zealand growers began calling it kiwifruit to give it more market appeal, in Italy, kiwifruit cultivation began in 1970, growing to rank second in production behind China in 2014. The genus Actinidia contains around 60 species, though most kiwifruit are easily recognized as kiwifruit their fruit is quite variable. The skin of the fruit varies in size, shape, hairiness, the flesh varies in color, juiciness, texture, and taste. Some fruits are unpalatable while others taste considerably better than the majority of the commercial varieties, the most common kiwifruit is the fuzzy kiwifruit, from the species A. deliciosa. Other species that are eaten include golden kiwifruit, Chinese egg gooseberry, baby kiwifruit, Arctic kiwifruit, red kiwifruit, silver vine. Almost all kiwifruit sold belong to a few cultivars of fuzzy kiwi, Hayward, Blake and they have a fuzzy, dull-brown skin, and bright-green flesh. The familiar cultivar Hayward was developed by Hayward Wright in Avondale and it was initially grown in domestic gardens, but commercial planting began in the 1940s

Oak
–
An oak is a tree or shrub in the genus Quercus of the beech family, Fagaceae. There are approximately 600 extant species of oaks, the common name oak also appears in the names of species in related genera, notably Lithocarpus, as well as in those of unrelated species such as Grevillea robusta and the Casuarinaceae. North America contains the largest number of oak species, with approximately 90 occurring in the United States, the second greatest center of oak diversity is China, which contains approximately 100 species. Oaks have spirally arranged leaves, with lobate margins in many species, also, the acorns contain tannic acid, as do the leaves, which helps to guard from fungi and insects. Many deciduous species are marcescent, not dropping dead leaves until spring, in spring, a single oak tree produces both male flowers and small female flowers. The fruit is a nut called an acorn, borne in a structure known as a cupule, each acorn contains one seed and takes 6–18 months to mature. The live oaks are distinguished for being evergreen, but are not actually a distinct group, the oak tree is a flowering plant. Oaks may be divided into two genera and a number of sections, The genus Quercus is divided into the following sections, Quercus, the white oaks of Europe, Asia and North America. Styles are short, acorns mature in 6 months and taste sweet or slightly bitter, the leaves mostly lack a bristle on their lobe tips, which are usually rounded. The type species is Quercus robur, Mesobalanus, Hungarian oak and its relatives of Europe and Asia. Styles long, acorns mature in about 6 months and taste bitter, the section Mesobalanus is closely related to section Quercus and sometimes included in it. Cerris, the Turkey oak and its relatives of Europe and Asia, styles long, acorn mature in 18 months and taste very bitter. The inside of the shell is hairless. Its leaves typically have sharp tips, with bristles at the lobe tip. Protobalanus, the live oak and its relatives, in southwest United States. Styles short, acorns mature in 18 months and taste very bitter, the inside of the acorn shell appears woolly. Leaves typically have sharp tips, with bristles at the lobe tip. Lobatae, the red oaks of North America, Central America, styles long, acorns mature in 18 months and taste very bitter

Yangtze
–
The Yangtze River, known in China as the Cháng Jiāng or the Yángzǐ Jiāng, is the longest river in Asia and the third-longest in the world. The river is the longest in the world to flow entirely within one country and it drains one-fifth of the land area of the Peoples Republic of China and its river basin is home to one-third of the countrys population. The Yangtze is the sixth-largest river by volume in the world. The Yangtze River plays a role in the history, culture. The prosperous Yangtze River Delta generates as much as 20% of the PRCs GDP, for thousands of years, the river has been used for water, irrigation, sanitation, transportation, industry, boundary-marking and war. The Three Gorges Dam on the Yangtze River is the largest hydro-electric power station in the world, in recent years, the river has suffered from industrial pollution, agricultural run-off, siltation, and loss of wetland and lakes, which exacerbates seasonal flooding. Some sections of the river are now protected as nature reserves, a stretch of the upstream Yangtze flowing through deep gorges in western Yunnan is part of the Three Parallel Rivers of Yunnan Protected Areas, a UNESCO World Heritage Site. In mid-2014 the Chinese government announced it was building a transport network, comprising railways, roads and airports. Because the source of the Yangtze was not ascertained until modern times, Yangtze was actually the name of Chang Jiang for the lower part from Nanjing to the river mouth at Shanghai. In modern Chinese, Yangtze is still used to refer to the part of Chang Jiang from Nanjing to the river mouth. Yangtze never stands for the whole Chang Jiang, Chang Jiang is the modern Chinese name for the lower 2,884 km of the Yangtze from its confluence with the Min River at Yibin in Sichuan Province to the river mouth at Shanghai. Chang Jiang literally means the Long River, in Old Chinese, this stretch of the Yangtze was simply called Jiang/Kiang 江, a character of phono-semantic compound origin, combining the water radical 氵 with the homophone 工. Krong was probably a word in the Austroasiatic language of local peoples such as the Yue, similar to *krong in Proto-Vietnamese and krung in Mon, all meaning river, it is related to modern Vietnamese sông and Khmer kôngkea. By the Han Dynasty, Jiang had come to any river in Chinese. The epithet 長, means long, was first formally applied to the river during the Six Dynasties period, various sections of Chang Jiang have local names. From Yibin to Yichang, the river through Sichuan and Chongqing Municipality is also known as the Chuan Jiang or Sichuan River, in the Hubei Province, the river is also called the Jing Jiang or the Jing River after Jingzhou. In Anhui Province, the takes on the local name Wan Jiang after the shorthand name for Anhui. And Yangzi Jiang t 揚子江s 扬子江, p Yángzǐjiāng) or the Yangzi River, the name likely comes from an ancient ferry crossing called Yangzi or Yangzijin

Herbarium
–
A herbarium is a collection of preserved plant specimens and associated data used for scientific study. The term can refer to the building or room where the specimens are housed. The specimens in a herbarium are used as reference material in describing plant taxa. The same term is used in mycology to describe an equivalent collection of preserved fungi. A xylarium is a herbarium specialising in specimens of wood, the term hortorium has occasionally been applied to a herbarium specialising in preserving material of horticultural origin. During the drying process the specimens are retained within their flimsies at all times to minimise damage, for some plants it may prove helpful to allow the fresh specimen to wilt slightly before being arranged for the press. The sheet is placed in a protective case. As a precaution against insect attack, the plant is frozen or poisoned. Certain groups of plants are soft, bulky, or otherwise not amenable to drying and mounting on sheets, for these plants, other methods of preparation and storage may be used. For example, conifer cones and palm fronds may be stored in labelled boxes, representative flowers or fruits may be pickled in formaldehyde to preserve their three-dimensional structure. Small specimens, such as mosses and lichens, are often air-dried and packaged in paper envelopes. No matter the method of preservation, detailed information on where and when the plant was collected, habitat, color, and the name of the collector is usually included. The value of a herbarium is much enhanced by the possession of “types”, that is and it is also rich in types of Australian plants from the collections of Sir Joseph Banks and Robert Brown, and contains in addition many valuable modern collections. Most herbaria utilize a system of organizing their specimens into herbarium cases. Specimen sheets are stacked in groups by the species to which they belong, groups of species folders are then placed together into larger, heavier folders by genus. The genus folders are then sorted by taxonomic family according to the standard selected for use by the herbarium. Locating a specimen filed in the herbarium requires knowing the nomenclature and it also requires familiarity with possible name changes that have occurred since the specimen was collected, since the specimen may be filed under an older name. Modern herbaria often maintain electronic databases of their collections, many herbaria have initiatives to digitize specimens to produce a virtual herbarium

Japan
–
Japan is a sovereign island nation in Eastern Asia. Located in the Pacific Ocean, it lies off the eastern coast of the Asia Mainland and stretches from the Sea of Okhotsk in the north to the East China Sea, the kanji that make up Japans name mean sun origin. 日 can be read as ni and means sun while 本 can be read as hon, or pon, Japan is often referred to by the famous epithet Land of the Rising Sun in reference to its Japanese name. Japan is an archipelago consisting of about 6,852 islands. The four largest are Honshu, Hokkaido, Kyushu and Shikoku, the country is divided into 47 prefectures in eight regions. Hokkaido being the northernmost prefecture and Okinawa being the southernmost one, the population of 127 million is the worlds tenth largest. Japanese people make up 98. 5% of Japans total population, approximately 9.1 million people live in the city of Tokyo, the capital of Japan. Archaeological research indicates that Japan was inhabited as early as the Upper Paleolithic period, the first written mention of Japan is in Chinese history texts from the 1st century AD. Influence from other regions, mainly China, followed by periods of isolation, from the 12th century until 1868, Japan was ruled by successive feudal military shoguns who ruled in the name of the Emperor. Japan entered into a period of isolation in the early 17th century. The Second Sino-Japanese War of 1937 expanded into part of World War II in 1941, which came to an end in 1945 following the bombings of Hiroshima and Nagasaki. Japan is a member of the UN, the OECD, the G7, the G8, the country has the worlds third-largest economy by nominal GDP and the worlds fourth-largest economy by purchasing power parity. It is also the worlds fourth-largest exporter and fourth-largest importer, although Japan has officially renounced its right to declare war, it maintains a modern military with the worlds eighth-largest military budget, used for self-defense and peacekeeping roles. Japan is a country with a very high standard of living. Its population enjoys the highest life expectancy and the third lowest infant mortality rate in the world, in ancient China, Japan was called Wo 倭. It was mentioned in the third century Chinese historical text Records of the Three Kingdoms in the section for the Wei kingdom, Wa became disliked because it has the connotation of the character 矮, meaning dwarf. The 倭 kanji has been replaced with the homophone Wa, meaning harmony, the Japanese word for Japan is 日本, which is pronounced Nippon or Nihon and literally means the origin of the sun. The earliest record of the name Nihon appears in the Chinese historical records of the Tang dynasty, at the start of the seventh century, a delegation from Japan introduced their country as Nihon

Hubei
–
Hubei is a province of the Peoples Republic of China, located in the Central China region. The name of the province north of the lake, referring to its position north of Dongting Lake. The provincial capital is Wuhan, a major thoroughfare and the political, cultural. It borders Henan to the north, Anhui to the east, Jiangxi to the southeast, Hunan to the south, Chongqing to the west, the high-profile Three Gorges Dam is located at Yichang, in the west of the province. The Hubei region was home to sophisticated Neolithic cultures, by the Spring and Autumn period, the territory of todays Hubei was part of the powerful State of Chu. During the Warring States period Chu became the major adversary of the upstart State of Qin to the northwest, which began to assert itself by outward expansionism. As wars between Qin and Chu ensued, Chu lost more and more land, first its dominance over the Sichuan Basin, then its heartland, which correspond to modern Hubei. In 223 BC Qin chased down the remnants of the Chu regime, Qin founded the Qin dynasty in 221 BC, the first unified state in the region. Qin was succeeded by the Han dynasty in 206 BC, which established the province of Jingzhou in what is now Hubei, the Qin and Han played an active role in the agricultural colonization of Hubei, maintaining a system of river dikes to protect farmland from summer floods. Towards the end of the Han Dynasty in the beginning of the 3rd century, the incursion of northern nomadic peoples into the region at the beginning of the 4th century began nearly three centuries of division into a nomad-ruled north and a Han Chinese-ruled south. Hubei, to the South, remained under southern rule for this entire period, until the unification of China by the Sui dynasty in 589. After the Tang dynasty disintegrated in the 10th century, Hubei came under the control of several regional regimes, Jingnan in the center, Wu to the east, and the Five Dynasties to the north. The Song dynasty reunified the region in 982 and placed most of Hubei into Jinghubei Circuit, Mongols conquered the region in 1279, and under their rule the province of Huguang was established, covering Hubei, Hunan, and parts of Guangdong and Guangxi. The Ming dynasty drove out the Mongols in 1368 and their version of Huguang province was smaller, and corresponded almost entirely to the modern provinces of Hubei and Hunan combined. While Hubei was geographically removed from the centers of the Ming power, during the last years of the Ming, todays Hubei was ravaged several times by the rebel armies of Zhang Xianzhong and Li Zicheng. The Manchu Qing dynasty which had much of the region in 1644, soon split Huguang into the provinces of Hubei. The Huangshi/Daye area, south-east of Wuhan, became an important center of mining, in 1911 the Wuchang Uprising took place in modern-day Wuhan, overthrowing the Qing dynasty and establishing the Republic of China. In 1927 Wuhan became the seat of a government established by left-wing elements of the Kuomintang, led by Wang Jingwei, during World War II the eastern parts of Hubei were conquered and occupied by Japan while the western parts remained under Chinese control
