145-819: The Grand Canal's main stem , known to the Chinese as the Jing – Hang Grand Canal , is thought to extend for 1,776 km (1,104 mi) and is divided into 6 main subsections. The Jiangnan Canal runs from the Qiantang River at Hangzhou to the Yangtze River at Zhenjiang ; the Inner Canal from the Yangtze at Yangzhou to the Huai River at Huai'an , which for centuries was also its junction with

290-690: A dam to divert the Wen River to the southwest in order to feed 60% of its water north into the Grand Canal, with the remainder going south. They dug four large reservoirs in Shandong to regulate water levels, which allowed them to avoid pumping water from local sources and water tables. Between 1411 and 1415 a total of 165,000 laborers dredged the canal bed in Shandong and built new channels, embankments, and canal locks . The Yongle Emperor moved

435-434: A river , as contrasted to its tributaries ". The mainstem extends all the way from one specific headwater to the outlet of the river, although there are multiple ways to determine which headwater (or first-order tributary) is the source of the mainstem. Water enters the mainstem from the river's drainage basin , the land area through which the mainstem and its tributaries flow. A drainage basin may also be referred to as

580-474: A watershed or catchment . Hydrological classification systems assign numbers to tributaries and mainstems within a drainage basin. In the Strahler number , a modification of a system devised by Robert E. Horton in 1945, channels with no tributaries are called "first-order" streams. When two first-order streams meet, they are said to form a second-order stream; when two second-order streams meet, they form

725-490: A circling retreat to the west and north, which reportedly traversed over 9,000 kilometers over 370 days." The route passed through some of the most difficult terrain of western China by traveling west, and then northwards towards Shaanxi. "In November 1935, shortly after settling in northern Shaanxi, Mao officially took over Zhou Enlai's leading position in the Red Army. Following a major reshuffling of official roles, Mao became

870-658: A direct north–south waterway for the first time. As in the Song and Jin era, the canal fell into disuse and dilapidation during the Yuan dynasty's decline. The Grand Canal as infrastructure has had influence on other architectural works in the west. The Erie Canal in North America is designed and draws inspiration from the Chinese architecture. Many saw the canal as an economic advantage that could bring economic prosperity, like

1015-815: A fierce battle, the CCP captured Jinan and Shandong province on 24 September 1948. The Huaihai Campaign of late 1948 and early 1949 secured east-central China for the CCP. A large number of KMT troops deserted and changed sides in these conflicts. The outcome of these encounters were decisive for the military outcome of the civil war. The Pingjin Campaign resulted in the Communist conquest of northern China. It lasted 64 days, from 21 November 1948 to 31 January 1949. The PLA suffered heavy casualties while securing Zhangjiakou , Tianjin along with its port and garrison at Dagu and Beiping . The CCP brought 890,000 troops from

1160-476: A flood or other disaster impeded the path of shipment. To ensure smooth travel of grain shipments, Transport Commissioner Liu Yan (in office from 763 to 779) had special river barge ships designed and constructed to fit the depths of each section of the entire canal. After the An Lushan rebellion (755–763), the economy of North China was greatly damaged and never recovered due to wars and to constant flooding of

1305-701: A founding member of the CCP, was never able to challenge Mao's authority. Essentially, the great retreat made Mao the undisputed leader of the Chinese Communist Party. The Kuomintang used Khampa troops—who were former bandits—to battle the Communist Red Army as it advanced and to undermine local warlords who often refused to fight Communist forces to conserve their own strength. The KMT enlisted 300 "Khampa bandits" into its Consolatory Commission military in Sichuan, where they were part of

1450-660: A further canal on the Tonghui River connected Tongzhou with a wharf called the Houhai or "rear sea" in central Beijing. In the Ming and Qing dynasties, however, the water level in the Tonghui River dropped and ships could not travel from Tongzhou to Beijing. Tongzhou then became the northern shipping terminus of the canal. Cargo was unloaded at Tongzhou and transported to Beijing by land. The Tonghui river still exists as

1595-468: A gated space while the water could be drained to appropriate levels; the Chinese also built roofed hangars over the space to add further protection for the ships. Much of the Grand Canal was ruined for several years after 1128 when Kaifeng's governor Du Chong ( 杜 充 , Dù Chōng , d.   1141) decided to break the dykes and dams holding back the waters of the Yellow River in order to decimate

1740-572: A man named Li Hualong created the Jia Canal. Named after the Jia River whose course it followed, it ran 140 kilometers (87 mi) from Xiazhen (modern Weishan) on the shore of Shandong's Weishan Lake to Suqian in Jiangsu. The construction of the Jia Canal left only 100 kilometers (62 mi) of Yellow River navigation on the Grand Canal, from Suqian to Huai'an, which by 1688 had been removed by

1885-547: A memorandum to the throne of the Yongle Emperor protesting the current inefficient means of transporting 4,000,000 dan (428,000,000 liters ) of grain a year by means of transferring it along several different rivers and canals in barge types that went from deep to shallow after the Huai River , and then transferred back onto deep barges once the shipment of grain reached the Yellow River . Chinese engineers built

2030-611: A rapid courier system. Enormous lines of trees were also planted along parts of the canal as windbreaks. Although the Tang dynasty (618–907) capital at Chang'an was the most thriving metropolis of China in its day, it was the city of Yangzhou —in proximity to the Grand Canal—that was the economic hub of the Tang era. Besides being the headquarters for the government salt monopoly and the largest pre-modern industrial production center of

2175-457: A renovated stone channel, it reaches the city of Linqing on the Shandong – Hebei border. Liangshan County is the northern terminus of the canal for barge traffic. The fifth section of the canal extends for a distance of 524 kilometers (326 mi) from Linqing to Tianjin along the course of the canalized Wei River . Though one of the northernmost sections, its name derives from its position relative to Tianjin. The Wei River at this point

2320-419: A series of lakes—Zhaoyang, Dushan, and Nanyang—which nominally form a continuous body of water. At present, diversions of water mean that the lakes are often largely dry land. North of the northernmost Nanyang Lake is the city of Jining . Further on, about 30 km (19 mi) north of Jining, the highest elevation of the canal (38.5 m or 126 ft above sea level) is reached at the town of Nanwang . In

2465-574: A single strike, this time the KMT troops patiently built blockhouses, each separated by about eight kilometres (five miles), to surround the Communist areas and cut off their supplies and food sources. In October 1934, the CCP took advantage of gaps in the ring of blockhouses (manned by the forces of a warlord ally of Chiang Kai-shek's, rather than regular KMT troops) and broke out of the encirclement. The warlord armies were reluctant to challenge Communist forces for fear of losing their own men and did not pursue

2610-545: A smooth and efficient canal system. The city of Kaifeng grew to be a major hub, later becoming the capital of the Song dynasty (960–1279). Although the Tang and Song dynasty international seaports—the greatest being Guangzhou and Quanzhou , respectively—and maritime foreign trade brought merchants great fortune, it was the Grand Canal within China that spurred the greatest amount of economic activity and commercial profit. During

2755-585: A substantial amount of their own supplies to the Communists, who received Northeastern China from the Soviets as well. In March 1946, despite repeated requests from Chiang, the Soviet Red Army under the command of Marshal Rodion Malinovsky continued to delay pulling out of Manchuria, while Malinovsky secretly told the CCP forces to move in behind them, which led to full-scale war for the control of

2900-584: A third-order stream, and so on. In the Horton system, the entire mainstem of a drainage basin was assigned the highest number in that basin. However, in the Strahler system, adopted in 1957, only that part of the mainstem below the tributary of the next highest rank gets the highest number. In the United States, the Mississippi River mainstem achieves a Strahler number of 10, the highest in

3045-423: A total power vacuum of local Chinese forces. Consequently, the 700,000 Japanese troops stationed in the region surrendered. Later in the year Chiang Kai-shek realized that he lacked the resources to prevent a CCP takeover of Manchuria following the scheduled Soviet departure. He therefore made a deal with the Soviets to delay their withdrawal until he had moved enough of his best-trained men and modern materiel into

3190-722: A wide, concrete-lined storm-channel and drain for the suburbs of Beijing. The Eastern Zhejiang Canal runs 239 kilometers (149 mi) across the coastal plain south of Hangzhou Bay in northern Zhejiang. It begins at the Qiantang River in Xixing, Binjiang District , Hangzhou; crosses the Cao'e River in Shaoxing ; and connects to the Yong River and ports on the East China Sea at Ningbo . This Hangzhou–Ningbo canal began as

3335-466: Is heavily polluted while drought and industrial water extraction have left it too low to be navigable. The canal, now in Hebei province, passes through the cities of Dezhou and Cangzhou . Although to spectators, the canal appears to be a deep waterway in these city centers, its depth is maintained by weirs and the canal is all but dry where it passes through the surrounding countryside. At its terminus,

3480-856: Is currently navigable. Its course is today divided into seven sections. From south to north these are the Jiangnan Canal, the Li Canal, the Inner Canal, the Middle Canal, the Lu Canal, the South Canal, the North Canal, and the Tonghui River. Man-Made Lake Lianhu Training Lake "Lianhu" was used to feed water to the Grand Canal section near Jiangnan. Since the canal was man-made there was not enough naturally flowing water to keep

3625-810: Is generally divided into two phases with an interlude: from August 1927 to 1937, the First United Front alliance of the KMT and CCP collapsed during the Northern Expedition , and the Nationalists controlled most of China. From 1937 to 1945, hostilities were mostly put on hold as the Second United Front fought the Japanese invasion of China with eventual help from the Allies of World War II , although armed clashes between

Canal is utilized by barge traffic bringing coal and construction materials around northern Jiangsu Province. At Weishan Lake, both courses enter Shandong province. From here to Linqing , the canal is called the Lu or 'Shandong' Canal. It crosses

3915-655: The 12 April Incident , the White Terror, or the Shanghai massacre . This incident widened the rift between Chiang and Wang Jingwei , the leader of the left wing faction of the KMT. The left wing of the KMT also expelled CCP members from the Wuhan Government , which in turn was toppled by Chiang Kai-shek. The KMT resumed its campaign against warlords and captured Beijing in June 1928. Soon, most of eastern China

4060-785: The Autumn Harvest Uprising , led by Mao Zedong. Borodin then returned to the Soviet Union in October via Mongolia. In November, Chiang Kai-shek went to Shanghai and invited Wang to join him. On 11 December, the CCP started the Guangzhou Uprising , establishing a soviet there the next day, but lost the city by 13 December to a counter-attack under the orders of General Zhang Fakui . On 16 December, Wang Jingwei fled to France. There were now three capitals in China:

4205-600: The Central Plain . At the same time, Communist forces also began to counterattack in Northeastern China, North China and East China. By late 1948, the CCP captured the northern cities of Shenyang and Changchun and seized control of the Northeast after suffering numerous setbacks while trying to take the cities, with the decisive Liaoshen Campaign . The New 1st Army , regarded as the best KMT army,

4350-508: The Chinese government and UNESCO recognized the Eastern Zhejiang Canal from Hangzhou to Ningbo along the former Tongji and Yongji Canals as official components of the Grand Canal. The oldest sections of what is now the Grand Canal were completed in the early 5th century BC during the conflicts of China's Spring and Autumn period to provide supplies and transport routes for the states of Wu and Yue . The network

4495-702: The Empire of Japan . In 1930, the Central Plains War broke out as an internal conflict of the KMT; launched by Feng Yuxiang , Yan Xishan , and Wang Jingwei. The attention was turned to root out remaining pockets of CCP activity in a series of five encirclement campaigns . The first and second campaigns failed, and the third was aborted due to the Mukden Incident . The fourth campaign (1932–1933) achieved some early successes, but Chiang's armies were badly mauled when they tried to penetrate into

After this network's completion in 609, Emperor Yang was said to have led a flotilla of boats 105 km (65 mi) long from the north down to his southern capital at Yangzhou. This process again involved massive levies of conscripted labor and

Along the way, the Communist army confiscated property and weapons from local warlords and landlords, while recruiting peasants and the poor, solidifying its appeal to the masses. Of the 90,000–100,000 people who began the Long March from the Soviet Chinese Republic, only around 7,000–8,000 made it to Shaanxi. The remnants of Zhang's forces eventually joined Mao in Shaanxi, but with his army destroyed, Zhang, even as

Despite the importance of railways and roads in modern China, the People's Republic of China has worked to improve the navigability of the canal since the end of the Chinese Civil War and the portion south of the Yellow River remains in heavy use by barges carrying bulk cargo . Increasing concern over pollution in China and particularly

The exact date of the Hong Canal's construction is uncertain; it is first mentioned by the diplomat Su Qin in 330 BC when discussing state boundaries. The historian Sima Qian (145–90 BC) knew of no historical date for it, placing his discussion of it just after the legendary works of Yu the Great ; modern scholars now consider it to belong to

5365-673: The Song official and engineer Qiao Weiyue invented the pound lock in the 10th century. The canal has been admired by many visitors throughout its history, including the Japanese monk Ennin (794–864), the Persian historian Rashid al-Din Hamadani (1247–1318), the Korean official Choe Bu (1454–1504), and the Italian missionary Matteo Ricci (1552–1610). In the late Spring and Autumn period , King Fuchai of Wu (whose capital

After the Second Taiwan Strait Crisis , both tacitly ceased to engage in open conflict in 1979; however, no armistice or peace treaty has ever been signed. Following the collapse of the Qing dynasty and the 1911 Revolution , Sun Yat-sen assumed

Periodic flooding of the Yellow River threatened the safety and functioning of the canal while, during wartime, the rivers' high dikes were sometimes deliberately broken to delay or sweep away advancing enemy troops. Even so, restoration and improvement of the canal and its associated flood control works

Yuan was frustrated in a short-lived attempt to restore monarchy in China , and China fell into power struggle after his death in 1916. The Kuomintang (KMT), led by Sun Yat-sen, created a new government in Guangzhou to rival the warlords who ruled over large swathes of China and prevented

During the Mongol Yuan dynasty (1271–1368) the capital of China was moved to Beijing, eliminating the need for the canal arm flowing west to Kaifeng or Luoyang. A summit section was dug across the foothills of the Shandong massif during the 1280s, shortening the overall length by as much as 700 km (430 mi), making the total length about 1,800 km (1,100 mi) and linking Hangzhou and Beijing with

Grand Canal (China) - Misplaced Pages Continue

6090-435: The 1950s a new canal was dug to the south of the old summit section. The old summit section is now dry, while the new canal holds too little water to be navigable. About 50 km (31 mi) further north, passing close by Dongping Lake , the canal reaches the Yellow River. By this point waterless, it no longer connects to the river. It reappears again in Liaocheng City on the north bank where, intermittently flowing through

6235-454: The 1990s, canal barge crews could tell when they neared Hangzhou by the stench of the visibly black water they passed through. Similarly, fishermen on Dongping Lake in Shandong objected to the introduction of water from the Yangtze as part of the South-North Water Diversion Project when they saw it noticeably killing fish and affecting their catch. During the 21st century, increasing efforts have been made to improve environmental conditions along

6380-439: The 6th century BC. The reunification of China under the Sui dynasty (581–618) ended three centuries of chaos since the Upheaval of the Five Barbarians , and the renewed political stability allowed both the thorough repair of existing canals and flood control systems as well as the construction of new canals. The primary consideration of the Sui canals was the need to tap into the expanding economic and agricultural resources of

6525-539: The Beijing–Hangzhou and Sui and Tang canals as part of UNESCO's listing for the Grand Canal. The Grand Canal World Heritage site is composed of 31 sections and a number of accessory heritage sites. Though the canal nominally crosses the watersheds of five river systems, in reality, the variation between these is so low that it has only a single summit section. The elevation of the canal bed varies from 1 m below sea level at Hangzhou to 38.5 m above at its summit. At Beijing, it reaches 27 m, fed by streams flowing downhill from

6670-402: The CCP and Chiang's troops were temporarily avoided. In the last month of World War II in East Asia, Soviet forces launched the huge Manchurian Strategic Offensive Operation against the Japanese Kwantung Army in Manchuria and along the Chinese-Mongolian border. This operation destroyed the Kwantung Army in just three weeks and left the USSR occupying all of Manchuria by the end of the war in

6815-456: The CCP as the greater threat. Chiang refused to ally with the CCP, preferring to unite China by eliminating the warlord and CCP forces first. He believed his forces were too weak to face the Japanese Imperial Army ; only after unification could the KMT mobilize against Japan. He ignored the Chinese people's discontent and anger at the KMT policy of compromise with the Japanese, instead ordering KMT generals Zhang Xueliang and Yang Hucheng to suppress

6960-401: The CCP executed a "passive defense" strategy. It avoided the strong points of the KMT army and was prepared to abandon territory in order to preserve its forces. In most cases the surrounding countryside and small towns had come under Communist influence long before the cities. The CCP also attempted to wear out the KMT forces as much as possible. This tactic seemed to be successful; after a year,

7105-404: The CCP in 1943 with the propaganda piece China's Destiny , which questioned the CCP's power after the war, while the CCP strongly opposed Chiang's leadership and referred to his regime as fascist in an attempt to generate a negative public image. Both leaders knew that a deadly battle had begun between themselves. In general, developments in the Second Sino-Japanese War were to the advantage of

7250-430: The CCP to take the cities of Changsha , Shantou and Guangzhou. The Red Army consisting of mutinous former National Revolutionary Army (NRA) soldiers as well as armed peasants established control over several areas in southern China . KMT forces continued to attempt to suppress the rebellions. Then, in September, Wang Jingwei was forced out of Wuhan. September also saw an unsuccessful armed rural insurrection, known as

7395-433: The CCP was being supplied by the Soviet Union, the CCP was able to utilize a large number of weapons abandoned by the Japanese, including some tanks. When large numbers of well-trained KMT troops began to defect to the Communist forces, the CCP was finally able to achieve material superiority. The CCP's most effective political reform was its land reform policy. This drew the massive number of landless and starving peasants in

7540-402: The CCP was quickly suppressed the next day by the Nationalist government in Wuhan, led by Wang Jingwei. On 14 August, Chiang Kai-shek announced his temporary retirement, as the Wuhan faction and Nanjing faction of the Kuomintang were allied once again with common goal of suppressing the CCP after the earlier split. Wang Jingwei took the leadership of KMT after Chiang. Attempts were later made by

7685-414: The CCP with much fervor. In addition, the main KMT forces were preoccupied with annihilating Zhang Guotao 's army, which was much larger than Mao's. The massive military retreat of Communist forces lasted a year and covered what Mao estimated as 12,500 km (25,000 Li ); it became known as the Long March . This military retreat was undertaken by the Chinese Communist Party, led by Mao Zedong, to evade

7830-506: The CCP, as its guerrilla war tactics had won them popular support within the Japanese-occupied areas. However, the KMT had to defend the country against the main Japanese campaigns, since it was the legal Chinese government, a factor which proved costly to Chiang Kai-shek and his troops. Japan launched its last major offensive against the KMT, Operation Ichi-Go , in 1944, which resulted in the severe weakening of Chiang's forces. The CCP also suffered fewer losses through its guerrilla tactics. By

7975-559: The CCP. However, their provincial forces suffered significant casualties in battles against the Red Army. On 12 December 1936, the disgruntled Zhang and Yang conspired to kidnap Chiang and force him into a truce with the CCP. The incident became known as the Xi'an Incident. Both parties suspended fighting to form a Second United Front to focus their energies and fight the Japanese. In 1937, Japan launched its full-scale invasion of China and its well-equipped troops overran KMT defenders in northern and coastal China. The alliance of CCP and KMT

8120-574: The CCP. On 15 November 1945, the KMT began a campaign to prevent the CCP from strengthening its already strong base. At the same time, however, the return of the KMT also brought widespread graft and corruption, with an OSS officer remarking that the only winners were the Communists. In the winter of 1945–1946, Joseph Stalin commanded Marshal Rodion Malinovsky to give Mao Zedong most Imperial Japanese Army weapons that were captured. Chiang Kai-shek's forces pushed as far as Chinchow (Jinzhou) by 26 November 1945, meeting with little resistance. This

8265-400: The CCP. The CCP then began movements in opposition of the Northern Expedition , passing a resolution against it at a party meeting. Then, in March 1927, the KMT held its second party meeting where the Soviets helped pass resolutions against the Expedition and curbing Chiang's power. Soon, the KMT would be clearly divided. Throughout this time, the Soviet Union sent money and spies to support

8410-461: The CCP. Without their support, the CCP likely would have failed. This is evidenced by documents showing other communist parties in China at the time, one with as many as 10,000 members, which all failed without support from the Soviet Union. In early 1927, the KMT–CCP rivalry led to a split in the revolutionary ranks. The CCP and the left wing of the KMT decided to move the seat of the KMT government from Guangzhou to Wuhan , where communist influence

8555-484: The Communists. In 1936, Zhou Enlai and Zhang Xueliang grew closer, with Zhou even suggesting that he join the CCP. However, this was turned down by the Comintern in the USSR. Later on, Zhou persuaded Zhang and Yang Hucheng , another warlord, to instigate the Xi'an Incident. Chiang was placed under house arrest and forced to stop his attacks on the Red Army, instead focusing on the Japanese threat. During Japan's invasion and occupation of Manchuria , Chiang Kai-shek saw

It was fed by rivers flowing from east to west from the borders of the Shandong massif. North of the Jizhou Canal summit section, the Huitong Canal ran downhill, fed principally by the River Wen, to join the Wei River in the city of Linqing. In 1289, a geological survey preceded its one-year construction. The Huitong Canal, built by an engineer called Ma Zhizhen, ran across sharply sloping ground and

The Han Canal is known as the second oldest section of the later Grand Canal since the Hong Canal ( t   鴻溝 , s   鸿沟 , Hónggōu , "Canal of the Wild Geese" or "Far-Flung Canal") most likely preceded it. It linked the Yellow River near Kaifeng to

The situation came to a head in late 1940 and early 1941 when clashes between Communist and KMT forces intensified. Chiang demanded in December 1940 that the CCP's New Fourth Army evacuate Anhui and Jiangsu Provinces, due to its provocation and harassment of KMT forces in this area. Under intense pressure,

This 'Middle Canal' section runs from Huai'an to Weishan Lake , passing through Luoma Lake and following more than one course, the result of the impact of centuries of Yellow River flooding. After Pizhou , a northerly course passes through Tai'erzhuang to enter Weishan Lake at Hanzhuang bound for Nanyang and Jining (this course

9425-405: The Jizhou Canal. The Shanyang Canal originally opened onto the Yangtze a short distance south of Yangzhou . As the north shore of the Yangtze gradually silted up to create the sandbank island of Guazhou, it became necessary for boats crossing to and from the Jiangnan Canal to sail the long way around the eastern edge of that island. After a particularly rough crossing of the Yangtze from Zhenjiang,

9570-454: The KMT camp decreased as his power increased. On 7 April, Chiang and several other KMT leaders held a meeting, during which they proposed that Communist activities were socially and economically disruptive and had to be undone for the Nationalist revolution to proceed. On 12 April, many communists within the KMT were purged in Shanghai through hundreds of arrests and executions on the orders of General Bai Chongxi . The CCP referred to this as

9715-415: The KMT government occupied most of the banks, factories and commercial properties, which had previously been seized by the Imperial Japanese Army. They also conscripted troops at an accelerated pace from the civilian population and hoarded supplies, preparing for a resumption of war with the Communists. These hasty and harsh preparations caused great hardship for the residents of cities such as Shanghai, where

9860-576: The KMT had no forces, the Japanese surrendered to the Soviet Union. Chiang Kai-shek reminded Japanese troops to remain at their posts to receive the KMT, but Communist forces soon began taking surrenders from the Japanese and fighting those who resisted. General Wedemeyer of the United States Army became alarmed at these developments and wanted seven American divisions to be sent to China, but General Marshall replied that it should not be given priority over Japan and Korea. The first post-war peace negotiation, attended by both Chiang Kai-shek and Mao Zedong,

Highlighting the aid provided by the US to the KMT, the Communists' position was that the US was stirring domestic warfare and characterized the civil war as both a national revolution against the KMT and a revolution against US colonization and aggression. As postwar negotiations between

The reopening of the Grand Canal also benefited Suzhou over Nanjing since the former was in a better position on the main artery of the Grand Canal, and so it became Ming China's greatest economic center. The only other viable contender with Suzhou in the Jiangnan region

10295-480: The Nationalist government and the CCP failed, the civil war between these two parties resumed. This stage of war is referred to in mainland China and Communist historiography as the "War of Liberation" (Chinese: 解放战争 ; pinyin: Jiěfàng Zhànzhēng ). On 20 July 1946, Chiang Kai-shek launched a large-scale assault on Communist territory in North China with 113 brigades (a total of 1.6 million troops). Knowing their disadvantages in manpower and equipment,

On 4 August, the main forces of the Red Army left Nanchang and headed southwards for an assault on Guangdong. Nationalist forces quickly reoccupied Nanchang while the remaining members of the CCP in Nanchang went into hiding. A CCP meeting on 7 August confirmed the objective of the party was to seize the political power by force, but

10585-831: The New Fourth Army commanders complied. The following year they were ambushed by KMT forces during their evacuation, which led to several thousand deaths. It also ended the Second United Front, formed earlier to fight the Japanese. As clashes between the CCP and KMT intensified, countries such as the United States and the Soviet Union attempted to prevent a disastrous civil war. After the New Fourth Army incident, US President Franklin D. Roosevelt sent special envoy Lauchlin Currie to talk with Chiang Kai-shek and KMT party leaders to express their concern regarding

10730-622: The Northeast. These favorable conditions also facilitated many changes inside the Communist leadership: the more radical hard-line faction who wanted a complete military take-over of China finally gained the upper hand and defeated the careful opportunists. Before giving control to Communist leaders, on 27 March, Soviet diplomats requested a joint venture of industrial development with the Nationalist Party in Manchuria. Although General Marshall stated that he knew of no evidence that

10875-625: The Shanyin Canal excavated in Shaoxing by the Yue official Fan Li in the early 5th century BC during China's Spring and Autumn period . Despite the difficulty of connecting the route's various watersheds, the present route was completed with the construction of the Xixing Canal by the Jin official He Xun in the late 3rd century AD. The canal was an important artery of transport and supply for

11020-498: The Song and earlier periods, barge ships occasionally crashed and wrecked along the Shanyang Yundao section of the Grand Canal while passing the double slipways, and more often than not those were then robbed of the tax grain by local bandits. This prompted Qiao Weiyue, an Assistant Commissioner of Transport for Huainan , to invent a double-gate system known as the pound lock in the year 984. This allowed ships to wait within

11165-468: The Sui dynasty, Yuwen Kai, advised the digging of a new canal that would run parallel to the existing canal, diverging from it at Chenliu ( Yanzhou ). The new canal was to pass not Xuzhou but Suzhou , to avoid connecting with the Si River and instead make a direct connection with the Huai River just west of Lake Hongze . With the recorded labor of five million people under the supervision of Ma Shumou,

11310-571: The Yellow River, the increased development of an alternative sea route for grain-ships, and the opening of the Tianjin-Pukou Railway and the Beijing-Hankou Railway —the canal languished and for decades the northern and southern parts remained separate. Many of the canal sections fell into disrepair, and some parts were returned to flat fields. Even today, the Grand Canal has not fully recovered its importance prior to

11455-535: The Yellow River. Such a case occurred in the year 858 when an enormous flood along the Grand Canal inundated thousands of acres of farmland and killed tens of thousands of people in the North China Plain . Such an unfortunate event could reduce the legitimacy of a ruling dynasty by causing others to perceive it as having lost the Mandate of Heaven ; this was a good reason for dynastic authorities to maintain

11600-502: The Yellow River—overseen by engineer Liang Rui—established canal lock gates to regulate water levels for the canal. Double slipways were installed to haul boats over when the difference in water levels was too great for the flash lock to operate. Similarly, by the year 600, there were major buildups of silt on the bottom of the Hong Canal, obstructing river barges whose drafts were too deep for its waters. The chief engineer of

11745-519: The canal and its benefits. Matteo Ricci 's Journals describes the canal in great detail documenting the economic prosperity. The pound lock is one of the more notable features of the Erie canal that is directly connected to the infrastructure of the Grand Canal as it is used in other similar bodies of water. The Grand Canal was renovated almost in its entirety between 1411 and 1415 during the Ming dynasty (1368–1644). A magistrate of Jining, Shandong sent

11890-608: The canal at proper depth so that boats could travel through it. So a man-made lake was used to feed water to the Jiangnan section of the Grand Canal. It was protected by the Government from reclamation and any use of the lake water without proper taxation was deemed illegal. It was supposed to be protected from profitable exploitation, but because the government changed over the years, lake Lianhu had been reclaimed many times and it started to become more shallow. The government changed

12035-636: The canal joins the Hai River in the center of Tianjin City before turning north-west. In Tianjin, the canal heads northwest, for a short time following the course of the Yongding, a tributary of the Hai River , before branching off toward Tongzhou on the edge of the municipality of Beijing. It is here that the modern canal stops and that a Grand Canal Cultural Park has been built. During the Yuan dynasty,

12180-532: The canal were made after the Sui period to cut down on travel time, but overall no fundamental differences existed between the Sui Grand Canal and the Tang Grand Canal. By the year 735, it was recorded that about 149,685,400 kilograms (165,000 short tons) of grain were shipped annually along the canal. The Tang government oversaw canal lock efficiency and built granaries along the route in case

12325-634: The canal will likely continue. The provincial governments of Shandong , Jiangsu , and Zhejiang undertook dredging intended to increase shipping capacity by 40 percent by 2012. The central government has also made the main route of the Grand Canal the eastern path of the South-North Water Diversion Project , using enormous pumping stations to redirect water from the Yangtze Delta to the drier north. The canal became greatly polluted during China's industrialization. By

12470-420: The canal. Around Hangzhou, for instance, a $ 250 million restoration project begun in 2001 improved water quality to the point where it no longer produces a noticeable odor and is once again capable of supporting some fauna. On 22 June 2014, UNESCO 's Conference on World Heritage listed the Grand Canal as a World Heritage Site . As well as its present-day course, fourteen centuries of canal-building have left

12615-513: The chairman of the Military Commission, with Zhou and Deng Xiaoping as vice-chairmen." This marked Mao's position as the pre-eminent leader of the CCP, with Zhou in second position to him. The march ended when the CCP reached the interior of Shaanxi . Zhang Guotao 's army (Red 4th Front Army), which took a different route through northwest China, was largely destroyed by the forces of Chiang Kai-shek and his Chinese Muslim allies,

12760-578: The cities of Huai'an and Yangzhou . Here the land lying to the west of the canal is higher than its bed while the land to the east is lower. Historically the Shanghe region west of the canal has been prone to frequent flooding, while the Xiahe region to its east has been hit by less frequent but immensely damaging inundations caused by the failure of the Grand Canal levees. Recent works have allowed floodwaters from Shanghe to be diverted safely out to sea. Like

12905-591: The construction of the Middle Canal by Jin Fu. In 1566, to escape the problems caused by flooding of the Yellow River around Yutai (now on the western shore of Weishan Lake), the Nanyang New Canal was opened. It ran for 75 kilometers (47 mi) from Nanyang (now Nanyang Town, located in the center of Weishan Lake) to the small settlement of Liucheng (in the vicinity of modern Gaolou Village, Weishan County, Shandong) north of Xuzhou City. This change in effect moved

13050-470: The countryside into the Communist cause. This strategy enabled the CCP to access an almost unlimited supply of manpower for both combat and logistical purposes; despite suffering heavy casualties throughout many of the war's campaigns, manpower continued to grow. For example, during the Huaihai Campaign alone the CCP was able to mobilize 5,430,000 peasants to fight against the KMT forces. After

13195-539: The course of the canal in Shandong. This was foreseen by a Chinese official in 1447, who remarked that the flood-prone Yellow River made the Grand Canal like a throat that could be easily strangled (leading some officials to request restarting the grain shipments through the East China Sea ). In 1855 the dikes of the canal were opened to flood advancing troops of the Taiping Rebellion 's Northern Expedition . Because of various factors—the difficulty of crossing

13340-403: The economic lifeline of indigenous trade within China. The scholar Gu Yanwu of the early Qing dynasty (1644–1912) estimated that the previous Ming dynasty had to employ 47,004 full-time laborers recruited by the lijia corvée system in order to maintain the entire canal system. It is known that 121,500 soldiers and officers were needed simply to operate the 11,775 government grain barges in

13485-404: The effort of the central government to penetrate and destabilize local Han warlords such as Liu Wenhui . The government was seeking to exert full control over frontier areas against the warlords. Liu had refused to battle the Communists in order to conserve his army. The Consolatory Commission forces were used to battle the Red Army, but they were defeated when their religious leader was captured by

13630-466: The empire, Yangzhou was also the geographical midpoint along the north–south trade axis, and so became the major center for southern goods shipped north. One of the greatest benefits of the canal system in the Tang dynasty—and subsequent dynasties—was that it reduced the cost of shipping grain that had been collected in taxes (caoyun) from the Yangtze Delta to northern China . Minor additions to

13775-540: The end of the war, the Red Army had grown to more than 1.3 million members, with a separate militia of over 2.6 million. About one hundred million people lived in CCP-controlled zones. Under the terms of the Japanese unconditional surrender dictated by the Allies, Japanese troops were to surrender to KMT troops but not to the CCP, which was present in some of the occupied areas. In Manchuria , however, where

13920-529: The first major section of the Grand Canal was completed in the year 605 and was called the Bian Qu. The Grand Canal was fully completed from the years 604 to 609 under Emperor Yang , first by linking his southern capital Yangzhou northwest to Luoyang by the Tongji Canal ( t 通 濟 渠 , s 通 济 渠 , Tōngjì Qú ). He then proceeded to connect Yangzhou southeast to Suzhou and Hangzhou by

14065-510: The floods of the mid-19th century. After the founding of the People's Republic of China in 1949, the need for economic development led the authorities to order heavy reconstruction work. The Grand Canal played a major role during Mao Zedong 's Great Leap Forward as it provided an efficient way to transport grain. It was further refurbished following Deng Xiaoping 's Reform and Opening Up , with improving economic conditions leading to greater infrastructure investment. The economic importance of

14210-707: The formation of a solid central government. After Sun's efforts to obtain aid from Western countries were ignored, he turned to the Soviet Union . In 1923, Sun and Soviet representative Adolph Joffe in Shanghai pledged Soviet assistance to China's unification in the Sun–Joffe Manifesto , a declaration of cooperation among the Comintern , KMT, and the Chinese Communist Party (CCP). Comintern agent Mikhail Borodin arrived in 1923 to aid in

14355-860: The former course of the Yellow River ; the Middle Canal from Huai'an to the Nansi Lakes ; the Lu Canal from the lakes past Jining and the present course of the Yellow River to the Wei River at Linqing ; the Southern Canal from Linqing to the Hai River at Tianjin ; and the Northern Canal from Tianjin to Tongzhou on the outskirts of Beijing. As such, it passes through the provinces and municipalities of Zhejiang , Jiangsu , Shandong , Hebei , Tianjin, and Beijing. In 2014,

14500-472: The groups remained common. Exacerbating the divisions within China further was the formation of the Wang Jingwei regime , a Japan-sponsored puppet government ostensibly led by Wang Jingwei , which was established to nominally govern the regions of China that came under Japanese occupation. The civil war resumed as soon as it became apparent that Japanese defeat was imminent, with the communists gaining

14645-591: The heart of Mao's Soviet Chinese Republic . During these campaigns, KMT columns struck swiftly into CCP areas, but were easily engulfed by the vast countryside and were not able to consolidate their foothold. Finally, in late 1934, Chiang launched a fifth campaign that involved the systematic encirclement of the Jiangxi Soviet region with fortified blockhouses . The blockhouse strategy was devised and implemented in part by newly hired Nazi advisors. Unlike previous campaigns in which they penetrated deeply in

14790-463: The high concentration of locks gave it the nicknames chahe or zhahe , i.e. 'the river of locks'. Its great number of feeder springs (between two and four hundred, depending on the counting method and season of the year) also led to it being called the quanhe or 'river of springs'. This, the Grand Canal's first true summit section, was engineered by the Mongol Oqruqči in 1238 to connect Jining to

14935-599: The highest-order river in the world. Chinese Civil War This is an accepted version of this page [REDACTED] China portal The Chinese Civil War was fought between the Kuomintang -led government of the Republic of China and the forces of the Chinese Communist Party (CCP), with armed conflict continuing intermittently from 1 August 1927 until Communist victory resulted in their total control over mainland China on 7 December 1949. The war

15080-420: The hostility between the two parties, with Currie stating that the only ones to benefit from a civil war would be the Japanese. The Soviet Union, allied more closely with the CCP, sent an imperative telegram to Mao in 1941, warning that civil war would also make the situation easier for the Japanese military. Due to the international community's efforts, there was a temporary and superficial peace. Chiang criticized

15225-552: The internationally recognized republic capital in Beijing , the CCP and left-wing KMT at Wuhan and the right-wing KMT regime at Nanjing , which would remain the KMT capital for the next decade. This marked the beginning of a ten-year armed struggle, known in mainland China as the "Ten-Year Civil War" (十年内战) which ended with the Xi'an Incident , when Chiang Kai-shek was forced to form the Second United Front against invading forces from

15370-467: The lake to become more profitable farmland which led to reclamations and agricultural irrigation using the lake. This began to lead to Lake Lianhu not being able to properly feed water to the Grand Canal. Loss of depth due to reclamation and maintenance costs became too high for the lake to become practical to use. Even though it was a man made lake it was still a beautiful sight. Many different people praised its beauty and various poems have been written about

15515-539: The lake. In recent years recreational uses for the lake have become more popular and may lead to the lake being restored. This southernmost section of the canal runs from Hangzhou in Zhejiang, where the canal connects with the Qiantang River, to Zhenjiang in Jiangsu, where it meets the Yangtze. After leaving Hangzhou heading north toward Beijing, the canal passes around the eastern border of Lake Tai , through

15660-414: The local prefect realized that a canal dug directly across Guazhou would reduce the journey time and thus make the crossing safer. The Yilou Canal was opened in 738 and still exists, though not as part of the modern Grand Canal route. The Grand Canal nominally runs between Beijing and Hangzhou over a total length of 1,794 km (1,115 mi); however, only the section from Hangzhou to Liangshan County

15805-463: The major cities of Jiaxing , Suzhou , Wuxi , and Changzhou before reaching Zhenjiang . The Jiangnan (or 'South of the Yangtze') Canal is heavily utilized by barge traffic bringing coal, containers and construction materials to the booming delta. It is generally a minimum of 100 meters wide in the congested city centers, and often two or three times this width in the neighboring countryside. In recent years, broad bypass canals have been dug around

15950-498: The major cities to reduce 'traffic jams'. The Suzhou section of the Jiangnan Canal flows through the western part of the city. It includes ten city gates and over 20 stone bridges of traditional design and historic areas that have been well preserved as well as temples and pavilions. The Inner Canal runs between the Yangtze and Huai rivers, skirting the Shaobo , Gaoyou , and Hongze lakes of central Jiangsu. This section connects

16095-417: The mid-15th century. Besides its function as a grain shipment route and major vein of river-borne indigenous trade in China, the Grand Canal had long been a government-operated courier route as well. In the Ming dynasty, official courier stations were placed at intervals of 35 to 45 km (22 to 28 mi). Each courier station was assigned a different name, all of which were popularized in travel songs of

16240-541: The mountains to the west. The water flows from Beijing toward Tianjin, from Nanwang north toward Tianjin, and from Nanwang south toward Yangzhou. The water level in the Jiangnan Canal remains scarcely above sea level (the Zhenjiang ridge is 12 meters higher than that of the Yangtze River). Main stem In hydrology , a main stem or mainstem (also known as a trunk ) is "the primary downstream segment of

16385-583: The nation. Eight rivers, including the Columbia River , reach 9. Streams with no tributaries, assigned the Strahler number 1, are most common. More than 1.5 million of these small streams, with average drainage basins of only 1 square mile (2.6 km ), have been identified in the United States alone. Outside of the United States, the Amazon River reaches a Strahler number of 12, making it

16530-451: The next generation of military leaders. The Soviets provided the academy with teaching material, organization, and equipment, including munitions. They also provided education in many of the techniques for mass mobilization. With this aid, Sun raised a dedicated "army of the party", with which he hoped to defeat the warlords militarily. CCP members were also present in the academy, and many of them became instructors, including Zhou Enlai , who

16675-403: The northeast to oppose some 600,000 KMT troops. There were 40,000 CCP casualties at Zhangjiakou alone. They in turn killed, wounded or captured some 520,000 KMT during the campaign. After achieving decisive victory at Liaoshen, Huaihai and Pingjin campaigns, the CCP destroyed 144 regular and 29 irregular KMT divisions, including 1.54 million veteran KMT troops, which significantly reduced

16820-582: The oncoming Jurchen invaders during the Jin–Song wars . Over a series of floods, this entirely shifted the river south of Shandong , capturing the course of the Si River and emptying the Yellow River into Hongze Lake and the East China Sea for centuries. The Jurchen Jin dynasty continually battled with the Song in this region. The warfare led to the dilapidation of the canal until the Mongols invaded in

16965-488: The period. The Manchus invaded China in the mid-17th century, allowed through the northern passes by the Chinese general Wu Sangui once the Ming capital at Beijing had fallen into the hands of a rebel army. The Manchus established the Qing dynasty (1644–1912), and under their leadership, the Grand Canal was overseen and maintained just as in earlier times. In 1855, the Yellow River flooded and changed its course , severing

17110-535: The power balance became more favorable to the CCP. They wiped out 1.12 million KMT troops, while their strength grew to about two million men. In March 1947, the KMT achieved a symbolic victory by seizing Yan'an, the capital of the Yan'an Soviet . The Communists counterattacked soon afterwards; on 30 June 1947, CCP troops crossed the Yellow River and moved to the Dabie Mountains area, restored and developed

17255-459: The power of the Chinese Communist Party grew considerably. Their main force grew to 1.2 million troops, backed with additional militia of 2 million, totalling 3.2 million troops. Their "Liberated Zone" in 1945 contained 19 base areas, including one-quarter of the country's territory and one-third of its population; this included many important towns and cities. Moreover, the Soviet Union turned over all of its captured Japanese weapons and

17400-628: The pursuit or attack of the Kuomintang army. It consisted of a series of marches, during which numerous Communist armies in the south escaped to the north and west. Over the course of the march from Jiangxi the First Front Army, led by an inexperienced military commission, was on the brink of annihilation by Chiang Kai-Shek's troops as their stronghold was in Jiangxi. The Communists, under the command of Mao Zedong and Zhou Enlai, "escaped in

17545-547: The region during periods of disunity in medieval China and was particularly prosperous and vital during the Southern Song , who established their capital at Lin'an within present-day Hangzhou. During the Yuan , Ming , and Qing , the canal diminished in importance but was kept navigable until the development of railways and roads in the 19th and 20th century. Renovation of the canal for use by modern barges began in 2002,

17690-512: The region. However, the Soviets refused permission for the Nationalist troops to traverse its territory and spent the extra time systematically dismantling the extensive Manchurian industrial base (worth up to $ 2 billion) and shipping it back to their war-ravaged country. KMT troops were then airlifted by the US to occupy key cities in North China, while the countryside was already dominated by

17835-619: The reorganization and consolidation of both the CCP and the KMT along the lines of the Communist Party of the Soviet Union . The CCP, which was initially a study group, and the KMT jointly formed the First United Front . In 1923, Sun sent Chiang Kai-shek , one of his lieutenants, for several months of military and political study in Moscow. Chiang then became the head of the Whampoa Military Academy that trained

17980-479: The southern end of the Huitong Canal. It rose to a height of 42 meters (138 ft) above the Yangtze, but environmental and technical factors left it with chronic water shortages until it was re-engineered in 1411 by Song Li of the Ming . Song Li's improvements, recommended by a local man named Bai Ying, included damming the rivers Wen and Guang and drawing lateral canals from them to feed reservoir lakes at

18125-636: The strength of Nationalist forces. Stalin initially favored a coalition government in postwar China, and tried to persuade Mao to stop the CCP from crossing the Yangtze and attacking the KMT positions south of the river. Mao rejected Stalin's position and on 21 April, began the Yangtze River Crossing Campaign . On 23 April, they captured the KMT's capital, Nanjing. The KMT government retreated to Canton (Guangzhou) until 15 October, Chongqing until 25 November, and then Chengdu before retreating to Taiwan on 7 December. By late 1949,

18270-538: The two Chinese leaders. It concluded with the signing of the Double Tenth Agreement . Both sides stressed the importance of a peaceful reconstruction, but the conference did not produce any concrete results. Battles between the two sides continued even as peace negotiations were in progress, until the agreement was reached in January 1946. However, large campaigns and full-scale confrontations between

18415-954: The unemployment rate rose dramatically to 37.5%. Hyperinflation meant those employed in the Kuomintang forces lost the purchasing power of their pay. This resulted in corruption and the embezzlement of supplies which disappeared into the barter economy. Ordinary Kuomintang soldiers were often malnourished and desertion was common. The US strongly supported the Kuomintang forces. About 50,000 US soldiers were sent to guard strategic sites in Hebei and Shandong in Operation Beleaguer . The US equipped and trained KMT troops, and transported Japanese and Koreans back to help KMT forces to occupy liberated zones as well as to contain Communist-controlled areas. According to William Blum , American aid included substantial amounts of mostly surplus military supplies, and loans were made to

18560-545: The upper hand in the second phase of the war from 1945 to 1949, generally referred to as the Chinese Communist Revolution . The Communists gained control of mainland China and proclaimed the People's Republic of China in 1949, forcing the leadership of the Republic of China to retreat to the island of Taiwan . Starting in the 1950s, a lasting political and military stand-off between the two sides of

18705-447: The use of the Grand Canal as the eastern path of the South-North Water Diversion Project —intended to provide clean potable water to the north—has led to regulations and several projects to improve water quality along the waterway. The greatest height on the canal is an elevation of 42 m (138 ft) above sea level reached in the foothills of Shandong. Ships in Chinese canals did not have trouble reaching higher elevations after

18850-668: The very summit, at a small town called Nanwang . In AD 369, General Huan Wen of the Eastern Jin dynasty connected the shallow river valleys of the Huai and the Yellow. He achieved this by joining two of these rivers' tributaries, the Si and the Ji respectively, at their closest point, across a low watershed of the Shandong massif. Huan Wen's primitive summit canal became a model for the engineers of

18995-456: The war with the Japanese ended, Chiang Kai-shek quickly moved KMT troops to newly liberated areas to prevent Communist forces from receiving the Japanese surrender. The US airlifted many KMT troops from central China to the Northeast (Manchuria). President Harry S. Truman was very clear about what he described as "using the Japanese to hold off the Communists". In his memoirs he writes: It

19140-457: Was Hangzhou, but it was located 200 km (120 mi) further down the Grand Canal and away from the main delta. Even the shipwrecked Korean Choe Bu (1454–1504)—while traveling for five months throughout China in 1488—acknowledged that Hangzhou served not as a competitor but as an economic feeder into the greater Suzhou market. Therefore, the Grand Canal served to make or break the economic fortunes of certain cities along its route and served as

19285-484: Was assumed as a duty by each successive dynasty. The canal played a major role in periodically reuniting northern and southern China, and officials in charge of the canal and nearby salt works grew enormously wealthy. Despite damage from floods , rebellions , and wars , the canal's importance only grew with the removal of the capital to Khanbaliq under the Mongol Yuan and to Beijing under Yongle Emperor of

19430-539: Was completed by Emperor Yang of the Sui dynasty in AD 609, linking the fertile Jiangnan region in the south to his capital at Luoyang in the west and to his armies in the far north. His unsuccessful and unpopular wars and the massive amounts of conscripted labor involved in creating the canal were among the chief factors in the rapid fall of the Sui, but the connection of China's major watersheds and population centers proved enormously beneficial. Additional canals supplied Chang'an (now Xi'an ) even further west under

19575-415: Was completed except for areas around Ningbo by 2009, and was fully completed in late 2013. In November 2008, the Eastern Zhejiang Canal was added to the Grand Canal's UNESCO nomination and, in May 2013, was officially included as part of the Grand Canal and listed among the 7th group of Major Historical and Cultural Sites Protected at the National Level by the Chinese government. In 2014, it was included with

19720-461: Was detailed at length in the Record of the Opening of the Canal ( t 《 開 河 記 》 , s 《 开 河 记 》 , Kāihéjì ). At this point, the Grand Canal continued to use noncontiguous artificial channels and both canalized and natural waterways rather than presenting a single continuous manmade canal. However, running alongside and parallel to the course of the canals was an imperial roadway with stables maintained at regular intervals to support

19865-412: Was followed by a Communist offensive on the Shandong Peninsula that was largely successful, as all of the peninsula, except what was controlled by the US, fell to the Communists. The truce fell apart in June 1946 when full-scale war between CCP and KMT forces broke out on 26 June 1946. China then entered a state of civil war that lasted more than three years. By the end of the Second Sino-Japanese War,

20010-422: Was forced to surrender after the CCP conducted a brutal six-month siege of Changchun that resulted in more than 150,000 civilian deaths from starvation. The capture of large KMT units provided the CCP with the tanks, heavy artillery and other combined-arms assets needed to execute offensive operations south of the Great Wall. By April 1948, the city of Luoyang fell, cutting the KMT army off from Xi'an. Following

20155-417: Was in Chongqing from 28 August to 10 October 1945. Chiang entered the meeting at an advantage because he had recently signed a friendly treaty with the Soviet Union while the Communists were still forcing the Japanese to surrender in some places. Mao was accompanied by American ambassador Patrick J. Hurley , who was devoted to Chiang but also wanted to ensure Mao's safety in light of the past history between

20300-403: Was in name only. Unlike the KMT forces, CCP troops shunned conventional warfare and instead waged guerrilla warfare against the Japanese. The level of actual cooperation and coordination between the CCP and KMT during World War II was minimal. In the midst of the Second United Front, the CCP and the KMT were still vying for territorial advantage in " Free China " (i.e., areas not occupied by

20445-449: Was in present-day Suzhou ), ventured north to attack the State of Qi . He ordered a canal to be constructed for trading purposes, as well as a means to ship ample supplies north in case his forces should engage the northern states of Song and Lu . This became known as the Han or Hangou Canal ( t 邗溝 , s 邗沟 , Hángōu ). Work began in 486 BC, from south of Yangzhou to north of Huai'an in Jiangsu, and within three years

20590-424: Was made a political instructor. Communist members were allowed to join the KMT on an individual basis. The CCP itself was still small at the time, having a membership of 300 in 1922 and only 1,500 by 1925. As of 1923, the KMT had 50,000 members. However, after Sun died in 1925, the KMT split into left- and right-wing movements. KMT members worried that the Soviets were trying to destroy the KMT from inside using

20735-438: Was perfectly clear to us that if we told the Japanese to lay down their arms immediately and march to the seaboard, the entire country would be taken over by the Communists. We therefore had to take the unusual step of using the enemy as a garrison until we could airlift Chinese National troops to South China and send Marines to guard the seaports. Using the pretext of "receiving the Japanese surrender", business interests within

20880-400: Was strong. However, Chiang and Li Zongren , whose armies defeated the warlord Sun Chuanfang , moved eastward toward Jiangxi . The leftists rejected Chiang's demand to eliminate Communist influence within KMT, and Chiang denounced them for betraying Sun Yat-sen's Three Principles of the People by taking orders from the Soviet Union. According to Mao Zedong , Chiang's tolerance of the CCP in

21025-404: Was under the control of the Nanjing central government, which received prompt international recognition as the sole legitimate government of China. The KMT government announced, in conformity with Sun Yat-sen, the formula for the three stages of revolution: military unification, political tutelage, and constitutional democracy. On 1 August 1927, the CCP launched an uprising in Nanchang against

#790209
