Wuhan in the context of "COVID-19 pandemic"

As of 2023, the five largest cities in China by population are Chongqing (31.91 million), Shanghai (24.87 million), Beijing (21.86 million), Chengdu (21.403 million) and Guangzhou (18.827 million). As of 2024, there are 18 megacities (cities with a population of over 10 million), including Chongqing, Shanghai, Beijing, Chengdu, Guangzhou, Shenzhen, Wuhan, Tianjin, Xi'an, Suzhou, Zhengzhou, Hangzhou, Shijiazhuang, Linyi, Dongguan, Qingdao, Changsha and Hefei.

Among them, the total permanent population of Chongqing, Shanghai, Beijing and Chengdu is above 20 million. Shanghai is China's most populous urban area, while Chongqing is its largest city proper, the only city in China with the largest permanent population of over 30 million.

The Northern Expedition was a military campaign launched by the National Revolutionary Army (NRA) of the Kuomintang (KMT) against the Beiyang government and other regional warlords in 1926. The purpose of the campaign was to reunify China, which had become fragmented in the aftermath of the 1911 Revolution. The expedition was led by Generalissimo Chiang Kai-shek, and was divided into two phases. The first phase ended in a 1927 political split between two factions of the KMT: the right-leaning Nanjing faction, led by Chiang, and the left-leaning faction in Wuhan, led by Wang Jingwei. The split was partially motivated by Chiang's Shanghai Massacre of Communists within the KMT, which marked the end of the First United Front. In an effort to mend this schism, Chiang Kai-shek stepped down as the commander of the NRA in August 1927, and went into exile in Japan.

The second phase of the Expedition began in January 1928, when Chiang resumed command. By April 1928, the nationalist forces had advanced to the Yellow River. With the assistance of allied warlords, including Yan Xishan and Feng Yuxiang, the nationalist forces secured a series of decisive victories against the Beiyang Army. As they approached Beijing, Zhang Zuolin, leader of the Manchuria-based Fengtian clique, was forced to flee and was later assassinated shortly thereafter by the Japanese. His son, Zhang Xueliang, took over as the leader of the Fengtian clique, and in December 1928, announced that Manchuria would accept the authority of the nationalist government in Nanjing. With the final piece of China under KMT control, the Northern Expedition concluded successfully and China was reunified, heralding the start of the Nanjing decade.

Hubei is a province in Central China. It has the seventh-largest economy among Chinese provinces, the second-largest within Central China, and the third-largest among inland provinces. Its provincial capital at Wuhan serves as a major political, cultural, and economic hub for the region.

Hubei is associated with the historical state of E that existed during the Western Zhou dynasty (c. 1045 – 771 BCE). Its name means 'north of the lake', referring to Dongting Lake. It borders Henan to the north, Anhui and Jiangxi to the east, Hunan to the south, and Chongqing and Shaanxi to the west. The high-profile Three Gorges Dam is located at Yichang in the west of the province.

Wang Zhaoming (4 May 1883 – 10 November 1944), widely known by his pen name Wang Jingwei, was a Chinese politician and poet who was president of the Reorganized National Government of the Republic of China, a puppet state of the Empire of Japan. He was initially a member of the left wing of the Kuomintang (KMT), leading a government in Wuhan in opposition to the centrist Nationalist government in Nanjing, but later became increasingly anti-communist after his efforts to collaborate with the Chinese Communist Party ended in political failure.

Wang was a close associate of Sun Yat-sen for the last twenty years of Sun's life. After Sun's death in 1925, Chiang Kai-shek, the leader of the centrist faction of Kuomintang, gradually became dominant among the party. Wang remained inside the Kuomintang, but continued to have disagreements with Chiang. Following the outbreak of the Second Sino-Japanese War in 1937, Wang accepted an invitation from the Japanese to form a collaborationist government in Nanjing, of which he served as the head of state until his death shortly before the End of World War II in Asia. Although he is still regarded as an important contributor in the 1911 Revolution, his collaboration with Imperial Japan is a subject of academic debate, and the typical narratives often regard him as a traitor with his name becoming synonymous with treason.

Shashi (Chinese: 沙市; pinyin: Shāshì) is a district within the main urban area of Jingzhou, Hubei province, China. It is located on the left (northern) bank of the Yangtze River, between Yichang and Wuhan.

The Wuchang Uprising was an armed rebellion against the ruling Qing dynasty that took place in Wuchang (now Wuchang District of Wuhan) in the Chinese province of Hubei on 10 October 1911, beginning the Xinhai Revolution that successfully overthrew China's last imperial dynasty. It was led by elements of the New Army, influenced by revolutionary ideas from Tongmenghui. The uprising and the eventual revolution led to the downfall of the Qing dynasty after almost three centuries of imperial rule, and the establishment of the Republic of China (ROC). Taiwan commemorates the anniversary of the uprising's outbreak on 10 October as the National Day of the Republic of China.

The uprising originated from popular unrest about a railway crisis, and the planning process took advantage of the situation. On 10 October 1911, the New Army stationed in Wuchang launched an assault on the residence of the Viceroy of Huguang. The viceroy Ruicheng quickly fled from the residence, and the revolutionaries soon took control of the entire city.

Severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) is a coronavirus that causes COVID-19, the respiratory illness responsible for the COVID-19 pandemic that began in late 2019. The virus previously had the provisional name 2019 novel coronavirus (2019-nCoV), and has also been called human coronavirus 2019 (HCoV-19 or hCoV-19). First identified in the city of Wuhan, Hubei, China, the World Health Organization designated the outbreak a public health emergency of international concern from January 30, 2020, to May 5, 2023. SARS‑CoV‑2 is a positive-sense single-stranded RNA virus that is contagious in humans.

SARS‑CoV‑2 is a virus of the species Betacoronavirus pandemicum (SARSr-CoV), as is SARS-CoV-1, the virus that caused the 2002–2004 SARS outbreak. Some animal-borne coronaviruses are more closely related to SARS-CoV-2 than SARS-CoV-1 is. The closest known relative is the BANAL-52 bat coronavirus. SARS-CoV-2 is of zoonotic origin; its close genetic similarity to bat coronaviruses suggests it emerged from such a bat-borne virus. Research is ongoing as to whether SARS‑CoV‑2 came directly from bats or indirectly through any intermediate hosts. The virus shows little genetic diversity, indicating that the spillover event introducing SARS‑CoV‑2 to humans is likely to have occurred in late 2019.
