Yan'an[a] is a prefecture-level city in the Shaanbei region of Shaanxi province, China, bordering Shanxi to the east and Gansu to the west. It administers several counties, including Zhidan (formerly Bao'an), which served as the headquarters of the Chinese Communist Party (CCP) before the city of Yan'an proper took that role.

Yan'an was near the endpoint of the Long March, and became the center of the Chinese Communist Revolution from late 1935 to early 1947. Chinese communists celebrate Yan'an as the birthplace of the revolution.

As of 2019, Yan'an has approximately 2,255,700 permanent residents.[2]: 4–5 

History

[edit]
Street in Yan'an, 1914

Yan'an was populated at least as early as the Xia dynasty.[3] During the Spring and Autumn period, the area was inhabited by the Beidi people.[3] During the Western Wei the area was organized as Yanzhou [zh].[3] Under the Sui dynasty, the area was re-organized as Yan'an Commandery [zh],[4] and a military base was established.[citation needed] The area became an important defensive outpost for the subsequent Tang dynasty,[5] which renamed the area Yanzhou in 758 CE.[3] Yanzhou was a location of strategic military importance for the Chinese empire and Tanguts of the Western Xia dynasty.[citation needed] It was once successfully defended by the Song dynasty era Chinese scientist, statesman, and general Shen Kuo.[citation needed] However, it was eventually taken over by the Tanguts in 1082 once Shen's defensive victories were marginalized and sacrificed by the new chancellor Cai Que (who handed the city over to the Tanguts as terms of a peace treaty).[citation needed] In 1089, under the Song dynasty, Yanzhou was renamed to Yan'an, and was promoted to a fu (Chinese: ).[3] Yan'an and the whole of Shaanxi were taken over by the Mongols in the late 1220s, only after their leader Genghis Khan had died during the siege of the Western Xia capital in 1227.[citation needed]

The demographic impacts of this was felt for decades, as the local economy cratered, and insufficient government support hindered recovery efforts:[6]: 128–129  In 1823, Bao'an (present-day Zhidan County) had a population of 51,000, but only 170 remained in 1868; while Yan'an (present-day Baota District) had 61,200 inhabitants in 1823, but only about 10,000 in 1930.[6]: 128  One account from a British traveler in 1911 described Yan'an as "a city of pretentious Government Offices long fallen into decay...Gazing down a vista of dim distant years one caught a glimpse of past splendour; but the living forces of which it had been the drapery and symbols had long since died out, leaving stagnation, corruption and decay to reign in its halls".[6]: 129–130 

After the fall of the Qing dynasty, the city became part of the newly created Republic of China, and was reorganized by the Republican government in 1913 under Yulin Circuit [zh].[3]

Throughout the Republic of China, feudal-like landlordism persisted in Yan'an, and a number of observers found it to be worse in the region than elsewhere in rural China.[6]: 134–135 

Red Capital and the Chinese Civil War

[edit]

In 1934, two regional soviets were established.[3] In October 1935, following the Long March, forces of the Chinese Red Army arrived in the area from Jiangxi.[3] The following month, communist forces established a regional government in Wayaobao and re-organized regional soviet administrations.[3] In May 1936, the area was re-organized by communist forces as Shaan-Gan-Ning Province (Chinese: 陕甘宁省).[3] In December 1936, at the start of the Second United Front, Yan'an was taken over by the Chinese Communists.[7] When Edgar Snow went there in 1936, it was under Kuomintang control and a Red army siege had recently been lifted.[8] Unknown to him at the time, there had also been contacts there between the Communists and the generals who later staged the Xi'an Incident.[citation needed] Snow actually met Mao at Bao'an (Pao An).[citation needed]

Having rebelled against Chiang, the local warlords decided to hand over Yan'an to the Communists, who were now allies. They pulled out, and in January 1937, the Red Army entered Yan'an,[3] without a fight. This is described by Agnes Smedley in her book Battle Hymn of China. She was in Xi'an at the time and got to Yan'an shortly after the take-over.[citation needed]

On September 6, 1937, Yan'an became the seat of the communist government of what became known as the Shaanxi-Gansu-Ningxia Border Region.[3] It became the center for intensive training of party members and army troops. Thousands of intellectuals traveled to Yan'an from all over the country.[9]: 123  From 1937 through 1941, the Communist government organized large-scale migrations to Yan'an, predominantly from Suide to the northeast, which was a significantly more densely populated area.[6]: 141  Many farmers from the region were attracted to Yan'an for the prospect of working more land, as well as the Communists' land and tax reforms.[6]: 141  From 1937 to 1939, over 1,500,000 mu of previously unused land was cleared for agriculture.[6]: 143  During this time, the large drive for intense rural labor earned its detractors, and was publicly criticized by some for "giving people a distaste for collective labour".[6]: 143  Subsequently, these types of large-scale labor projects would be handled by the army.[6]: 143  In 1941, Mao Zedong put special influence on a series of training programs to "correct unorthodox tendencies" and essentially mold the peasantry to the communist model. One of the first CCP programs launched was the Yan'an Rectification Movement.[10][11]

World War II and resumption of the Chinese Civil War

[edit]

During the Second World War almost all buildings, except a pagoda, were destroyed by Japanese bombing, and most inhabitants took to living in yaodongs, artificial caves or dugouts carved into hillsides which were traditional dwellings in Shaanxi.[citation needed] While Yan'an was the center of Chinese communist life many prominent Western journalists including Edgar Snow and Anna Louise Strong met with Mao Zedong and other important leaders for interviews.[citation needed] Other Westerners, such as Hsiao Li and Michael Lindsay, were part of the resistance movement in Yan'an.[12]

Beginning in 1944, Yan'an played host to the United States Army Observation Group, also known as the Dixie Mission.[13] This group sought to establish relations with Chinese Communist forces, investigate the Communist Party politically and militarily, and determine whether the United States should back Communist forces.[13] Prominent Americans tasked with evaluating the Communist forces politically and militarily include John S. Service of the United States Department of State, and Colonel David D. Barrett of the United States Army.[13] The mission explored possible plans for cooperation against the Japanese.[citation needed] The Americans had a presence in Yan'an from 1944 to 1947.[citation needed]

Yan'an was briefly captured in the Battle of Yan'an by the Kuomintang forces in the Chinese Civil War.[citation needed] The Communist leadership learned of a planned attack in advance and decided to pull out.[citation needed] From then until their capture of Beijing they were usually based somewhere else, often with a mobile headquarters.[citation needed]

People's Republic of China

[edit]

In May 1950, under the People's Republic of China, Yan'an was re-organized as Yan'an District, and was further re-organized as a special district (Chinese: 专区) in October.[3] Yan'an was later established as an area (Chinese: 地区).[3]

On November 5, 1996, Yan'an Area was revoked and established as a prefecture-level city.[3]

Yan'an's experienced fast-paced urbanization during the Eleventh Five-Year Plan period (2006–2010).[9]: 125  From 2011 to 2015, it underwent a red tourism-oriented beautification project.[9]: 127 

Xi Jinping visited Yan'an in 2015.[14]: 89  During the visit, he emphasized the importance of studying the Communist Party's history in Yan'an and called for a renewed focus on the principles of Marxism–Leninism, Mao Zedong Thought, and the party's revolutionary tradition.[14]: 89
