Second Sino-Japanese War


The Second Sino-Japanese War, known in China as the War of Resistance Against Japanese Aggression, was fought between the Republic of China and the Empire of Japan between 1937 and 1945, following a period of war localized to Manchuria that started in 1931. It is often regarded as the beginning of World War II in Asia, as the wars became heavily intertwined after Japan's entry into World War II. It was the largest Asian war in the 20th century.
On 18 September 1931, the Japanese staged the Mukden incident, a false flag event fabricated to justify their invasion of Manchuria and establishment of the puppet state of Manchukuo. This is sometimes marked as the beginning of the war. From 1931 to 1937, China and Japan engaged in skirmishes, including in Shanghai and in Northern China. Nationalist and Chinese Communist Party forces, respectively led by Chiang Kai-shek and Mao Zedong, had fought each other in the Chinese Civil War since 1927. In late 1933, Chiang Kai-shek encircled the Chinese Communists in an attempt to finally destroy them, forcing the Communists into the Long March, resulting in the Communists losing around 90% of their men. As a Japanese invasion became imminent, Chiang eventually formed a United Front with the Communists in 1936, a process that was hastened by the Xi'an Incident.
The war is considered to have begun on 7 July 1937 after the Marco Polo Bridge incident near Beijing, which escalated into full-scale Japanese invasion of the rest of China. The Japanese captured the capital of Nanjing in 1937 and perpetrated the Nanjing Massacre. After failing to stop the Japanese capture of Wuhan in 1938, China's de facto capital at the time, the Nationalist government relocated to Chongqing in the Chinese interior. After the Sino-Soviet Non-Aggression Pact, Soviet aid bolstered the National Revolutionary Army and Air Force. By 1939, after Chinese victories at Changsha and with Japan's lines of communications stretched deep into the interior, the war reached a stalemate. The Japanese were unable to defeat CCP forces in Shaanxi, who waged a campaign of sabotage and guerrilla warfare. In November 1939, Nationalist forces launched a large scale winter offensive, and in August 1940, CCP forces launched the Hundred Regiments Offensive in central China. In retaliation, Japanese forces implemented massive scorched earth policies in North and Central China, killing millions of civilians.
In April 1941, Soviet aid was halted with the Soviet–Japanese Neutrality Pact. In December 1941, Japan launched a surprise attack on Pearl Harbor and declared war on the United States. The US increased its aid to China under the Lend-Lease Act, becoming its main financial and military supporter. With Burma cut off, the United States Army Air Forces airlifted material over the Himalayas. In 1944, Japan launched Operation Ichi-Go, the invasion of Henan and Changsha. In 1945, the Chinese Expeditionary Force resumed its advance in Burma and completed the Ledo Road linking India to China. China launched large counteroffensives in South China, repulsed a failed Japanese invasion of West Hunan, and recaptured Japanese occupied regions of Guangxi.
Japan formally surrendered on 2 September 1945, following the atomic bombings of Hiroshima and Nagasaki, Soviet declaration of war and subsequent invasions of Manchukuo and Korea. The war resulted in the deaths of around 20 million people, mostly Chinese civilians. China was recognized as one of the Big Four Allied powers in World War II and one of the "Four Policemen", which formed the foundation of the United Nations. It regained Taiwan and became one of the five permanent members of the United Nations Security Council. The Chinese Civil War resumed in 1946, ending with a communist victory and the Proclamation of the People's Republic of China in 1949, while the government of the Republic of China relocated on Taiwan.

Names

Chinese

In China, the war is most commonly known as the "War of Resistance against Japanese Aggression", and the name of it is usually shortened to "Resistance against Japanese Aggression" or the "War of Resistance". In the PRC, it is also referred to as a part of the "World Anti-Fascist War" because during it, Imperial Japan was allied with Nazi Germany and Fascist Italy.
The war has often been termed the Eight Years' War of Resistance", a traditional view which dates the war's beginning to the Marco Polo Bridge incident in 1937. In the CCP's official view of Chinese historiography, the 18 September 1931 Japanese invasion of Manchuria marks the start of the" Fourteen Years' War of Resistance". In 2017, the Chinese government officially announced that it would adopt this view. Under this interpretation, the 1931–1937 period is viewed as the "partial" war, while 1937–1945 is viewed as a period of "total" war. This view of a fourteen-year war has political significance because it provides more recognition for the role of northeast China in the War of Resistance.

Japanese

In contemporary Japan, the name "Japan–China War" is most commonly used because of its perceived objectivity. Dating the beginning of the war may also vary in Japanese context, with one Japanese historiographical view regarding the war as a "Fifteen-Year War", covering the period beginning with the invasion of Manchuria through the atomic bombings, and including both the war in China and the Pacific war.
When the invasion of China proper began in earnest in July 1937 near Beijing, the Empire of Japan used "The North China Incident", and with the outbreak of the Battle of Shanghai the following month, it was changed to "The China Incident".
The word "incident" was used by Japan, as neither country had made a formal declaration of war at the outbreak of hostility. From the Japanese perspective, localizing these conflicts was beneficial in preventing intervention from other countries, particularly the United Kingdom and the United States, which were its primary source of petroleum and steel respectively. A formal expression of these conflicts would potentially lead to an American embargo in accordance with the Neutrality Acts of the 1930s. In addition, due to China's fractured political status, Japan often claimed that China was no longer a recognizable political entity on which war could be declared.
In Japanese propaganda, the invasion of China became a holy war, the first step of the "eight corners of the world under one roof" slogan. In 1940, Japanese prime minister Fumimaro Konoe launched the Taisei Yokusankai. When both sides formally declared war in December 1941, the name was replaced by "Greater East Asia War".
Although the Japanese government still uses the term "China Incident" in formal documents, the word Shina is considered derogatory by China and therefore the media in Japan often paraphrase with other expressions like "The Japan–China Incident", which were used by media as early as the 1930s.
The name "Second Sino-Japanese War" is not commonly used in Japan as the China it fought a war against in 1894 to 1895 was led by the Qing dynasty, and thus is called the Qing-Japanese War, rather than the First Sino-Japanese War.

Background

The First Sino-Japanese War concluded with the defeat of China, then under the rule of the Qing dynasty, by Japan. Under the Treaty of Shimonoseki, China was forced to cede Taiwan and recognize the full and complete independence of Korea. Japan also annexed the Senkaku Islands, which Japan claims were uninhabited, in early 1895 as a result of its victory at the end of the war. Japan had also attempted to annex the Liaodong Peninsula following the war, though was forced to return it to China following the Triple Intervention by France, Germany, and Russia. The Qing dynasty was on the brink of collapse due to internal revolts and the imposition of the unequal treaties, while Japan had emerged as a great power through its efforts to modernize. In 1905, Japan defeated the Russian Empire in the Russo-Japanese War, gaining Dalian and southern Sakhalin and establishing a protectorate over Korea.

Warlords in the Republic of China

In 1911, factions of the Qing Army uprose against the government, staging a revolution that swept across China's southern provinces. The Qing responded by appointing Yuan Shikai, commander of the loyalist Beiyang Army, as temporary prime minister in order to subdue the revolution. Yuan, wanting to remain in power, compromised with the revolutionaries, and agreed to abolish the monarchy and establish a new republican government, under the condition he be appointed president of China. The new Beiyang government of China was proclaimed in March 1912, after which Yuan Shikai began to amass power for himself. In 1913, the parliamentary political leader Song Jiaoren was assassinated; it is generally believed Yuan Shikai ordered the assassination. Yuan Shikai then forced the parliament to pass a bill to strengthen the power of the president and sought to restore the imperial system, becoming the new emperor of China.
However, there was little support for an imperial restoration among the general population, and protests and demonstrations soon broke out across the country. Yuan's attempts at restoring the monarchy triggered the National Protection War, and Yuan Shikai was overthrown after only a few months. In the aftermath of Shikai's death in June 1916, control of China fell into the hands of the Beiyang Army leadership. The Beiyang government was a civilian government in name, but in practice it was a military dictatorship with a different warlord controlling each province of the country. China was reduced to a fractured state. As a result, China's prosperity began to wither and its economy declined. This instability presented an opportunity for nationalistic politicians in Japan to press for territorial expansion.

Twenty-One Demands

In 1915, Japan issued the Twenty-One Demands to extort further political and commercial privilege from China, which was accepted by the regime of Yuan Shikai. Following World War I, Japan acquired the German Empire's sphere of influence in Shandong province, leading to nationwide anti-Japanese protests and mass demonstrations in China. The country remained fragmented under the Beiyang Government and was unable to resist foreign incursions. For the purpose of unifying China and defeating the regional warlords, the Kuomintang in Guangzhou launched the Northern Expedition from 1926 to 1928 with limited assistance from the Soviet Union.
