Yuan Shikai and the failure of the early republic

The 1911 Revolution brought Qing rule to an end, but it did not create a stable nation-state straight away. Sun Yixian, the leader of the Revolutionary Alliance, became provisional president of the Republic of China in January 1912. He soon handed the presidency to Yuan Shikai. Yuan’s military strength appeared necessary to secure the emperor’s abdication and avoid civil conflict.

Yuan quickly weakened constitutional government. The Guomindang did well in the 1912–1913 elections, but its leading parliamentary figure, Song Jiaoren, was assassinated in March 1913. Yuan then suppressed opposition, dissolved parliament and increasingly ruled through military power. His attempt to become emperor in 1915–1916 triggered provincial resistance and destroyed what remained of his credibility. After Yuan died in June 1916, central authority broke apart.

Yuan’s failure reinforced the idea that changing the form of government would not be enough. China also needed national unity, political participation and cultural renewal.

Sun Yixian and nationalism

Sun connected national reconstruction with his Three Principles of the People:

• Nationalism: ending foreign domination and building a united Chinese nation.
• Democracy: creating constitutional and representative government, although Sun first expected a period of political training.
• People’s livelihood: improving economic welfare and tackling unequal access to land and wealth.

Sun’s influence was initially greater than his practical power. He repeatedly failed to secure a territorial base and depended on alliances with provincial military leaders. Even so, his programme gave later Chinese nationalism a clear ideological structure.

The 21 Demands, 1915

In January 1915 Japan presented Yuan’s government with the 21 Demands. They sought broader Japanese privileges in Shandong, Manchuria and the Chinese economy. Some provisions would also have interfered deeply in China’s internal administration. Under Japanese pressure, the Chinese government accepted most of the revised demands in May. Japan withdrew most of Group V, although the provision concerning Fukien remained.

The episode revealed China’s diplomatic and military weakness. Public anger led to boycotts of Japanese goods. It also linked nationalism with opposition to foreign imperialism and to Chinese governments that could not defend the country’s sovereignty.

The New Culture Movement

The New Culture Movement developed from about 1915 among urban intellectuals and at institutions such as New Youth and Beijing University. Chen Duxiu, Hu Shi and other writers challenged inherited social hierarchies and demanded intellectual and cultural change.

Its main themes included:

• promotion of science, critical inquiry and individual freedom;
• use of written vernacular Chinese instead of the classical literary language;
• criticism of Confucian patriarchy and unquestioning obedience;
• wider educational and social opportunities for women;
• investigation of Western liberalism, socialism, anarchism and Marxism.

The movement did not speak for all Chinese people. Conservatives saw its attacks on tradition as culturally destructive. Radicals, meanwhile, increasingly decided that cultural reform needed organized political action.

Versailles and the May Fourth Movement

China entered the First World War on the Allied side and expected the post-war settlement to return the former German concessions in Shandong. Instead, the Treaty of Versailles of 1919 transferred Germany’s Shandong rights to Japan. China’s delegation eventually refused to sign the treaty.

On 4 May 1919, students in Beijing demonstrated against the settlement and against Chinese officials seen as pro-Japanese. The May Fourth Movement spread to other cities through student strikes, merchant boycotts and labour action. The government made concessions, including dismissing several officials. This showed that coordinated public protest could put real pressure on the government.

May Fourth brought together anti-imperialism, cultural reform, mass politics and demands for national regeneration. It increased support for both the Guomindang and new radical organizations, including the Chinese Communist Party, founded in 1921.

Effects of warlordism

Warlordism meant the exercise of regional political power by military commanders whose authority depended mainly on control of armed forces. From Yuan’s death in 1916 until the Nationalist advance of the 1920s, rival military groupings competed for Beijing, provincial territory and taxation.

Its effects were serious, although they varied from region to region. Warfare disrupted trade and agriculture. Repeated taxes, requisitions and forced recruitment placed heavy burdens on rural communities. Foreign governments could bargain with competing regimes, strengthening the impression that China lacked genuine sovereignty. Some regions, however, experienced periods of administrative reform, educational expansion or economic development under comparatively stable commanders.

Warlordism encouraged national identity in two ways. It showed the costs of political fragmentation and allowed both Nationalists and Communists to make a powerful claim: only a disciplined national movement could reunify China.

Guomindang leadership and ideology

The Guomindang (GMD) aimed to reunify China through a centralized party-state built on Sun Yixian’s Three Principles of the People. After Sun died in 1925, the military commander Jiang Jieshi gradually became the dominant figure.

With Soviet help, the GMD had been reorganized into a disciplined mass party. It linked political organization to the National Revolutionary Army, which was trained partly at the Whampoa Military Academy. Jiang then used the Northern Expedition of 1926–1928 to defeat or absorb the main warlord regimes. When Beijing fell in 1928, China was nominally reunified and the national government was established at Nanjing.

Sun had planned a sequence of military unification, political tutelage and, eventually, constitutional democracy. Jiang concentrated on the first two stages. The GMD argued that strong one-party leadership had to come before democratic government. That argument also gave Jiang a basis for political repression and personal control.

Jiang Jieshi’s system of rule

Jiang relied on several overlapping networks: the GMD party, the army, financial interests and agreements with provincial commanders. His control across China was uneven. Powerful regional leaders kept their armies and local influence, while rural government often relied on magistrates, landlords and local elites.

He also had to choose between resisting Japan and destroying the Chinese Communist Party. After Japan occupied Manchuria in 1931, critics attacked his decision to prioritize internal unity and communist suppression before launching full-scale resistance to Japan.

The New Life Movement, launched in 1934, called for discipline, order, cleanliness and supposedly traditional moral behaviour. It showed the regime’s attempt to reshape society from above. Its slogans, however, did little to address poverty, landlord power or unequal access to education.

Domestic achievements, 1927–1937

The Nanjing government achieved more than the idea of a completely chaotic China suggests.

These reforms had their greatest effect in cities and in areas firmly controlled from Nanjing. They demonstrated that the GMD could build institutions, but most rural lives changed very little.

Domestic failures

The regime’s main weakness was the gap between its national claims and its limited reach. Provincial militarists still held considerable influence, while military spending used resources that could have supported civilian reform. Corruption and patronage also damaged public trust.

Rural problems were particularly severe. Many peasants faced high rents, debt and numerous taxes. Landlords and local officials often blocked reform, and the government never carried out a thorough redistribution of land. Natural disasters and the effects of the worldwide economic depression made insecurity worse in some regions.

The GMD restricted political opposition. It suppressed communists, trade unionists and dissident critics, while failing to establish the representative government promised in Sun’s programme. Its urban and business supporters also made it reluctant to challenge property-owning elites.

Japanese aggression revealed further weaknesses. The loss of Manchuria in 1931 and growing Japanese pressure in northern China harmed Jiang’s nationalist credentials. The government had to divide its resources between state-building, campaigns against the communists and responses to Japanese pressure. It postponed full-scale war until 1937.

Judging the Nanjing decade

A state-building interpretation points to currency reform, infrastructure, legal modernization and the restoration of national institutions after years of fragmentation. A more critical interpretation focuses on the regime’s authoritarianism, social conservatism and dependence on military and elite support.

Both interpretations capture part of the period. The Nanjing decade brought genuine administrative consolidation, but it did not create a fully unified state or resolve China’s rural and social crises.

Political, economic and social foundations

The Chinese Communist Party was founded in 1921 by a small group of urban intellectuals. Ideology alone does not explain its later rise. The party benefited from weak central government, hardship in the countryside, Guomindang repression and its own ability to adapt Marxism to Chinese conditions.

Most Chinese people lived in rural areas. Conditions differed from one region to another, but many peasants faced high rents, debt, insecure tenancy, taxes and landlord power. Floods, drought, warfare and military requisitioning made life even less secure. Hardship did not automatically turn peasants into communists. Support grew when communist organization linked local grievances with practical promises about land, rents, taxation and protection.

The First United Front

The First United Front began to take shape in 1923 and was formally established in 1924. It brought the Guomindang and the Chinese Communist Party together to oppose warlordism and imperialism. Soviet advisers helped reorganize the GMD, while individual communists joined the GMD without formally dissolving their own party.

The alliance helped build a broader national movement and supported the Northern Expedition. Communists organized workers and peasants behind its advance. Landlords, business interests and conservative GMD leaders became alarmed, while competition for control of the revolutionary movement grew after Sun Yixian’s death.

The Shanghai massacre, 1927

In April 1927, Jiang Jieshi moved against communist-led unions and organizations in Shanghai. GMD forces and allied armed groups arrested and killed communists, trade unionists and suspected sympathizers. Similar purges took place elsewhere.

The Shanghai massacre destroyed the First United Front and sharply weakened communist influence in the major cities. It also redirected the revolution. Increasingly, survivors looked to secure rural bases and armed forces instead of relying mainly on urban workers.

The purge strengthened Jiang’s position and helped establish the Nanjing government. It did not, however, give him immediate complete control of the GMD or eliminate communism. Instead, it encouraged a movement better able to operate beyond the government’s strongest urban centres.

Mao Zedong and the peasantry

Mao Zedong argued that the peasantry could become China’s main revolutionary force. His approach focused more on rural organization, land reform, political education and guerrilla warfare than orthodox Marxist expectations of an urban proletarian revolution.

Mao’s leadership faced opposition. Some party leaders preferred urban action, while others followed military strategies closer to Soviet advice. His eventual rise reflected his ideas, but also the failure of rival approaches.

The Jiangxi Soviet, 1931–1934

The communists created several rural bases. The most important became the Jiangxi Soviet, formally organized in 1931 around Ruijin. Mao, Zhu De and other leaders developed the Red Army while experimenting with revolutionary government.

Communist policies included redistributing land, reducing landlord power, promoting literacy and political campaigns, and trying to involve women in public life. These policies were not applied consistently. Radical class policies could win support from poor peasants, but they could also frighten and provoke resistance among better-off villagers.

The GMD launched repeated encirclement campaigns against Jiangxi. The communists resisted the early campaigns with mobility, local intelligence and guerrilla tactics. During the Fifth Encirclement Campaign, which began in 1933, GMD blockhouses and economic pressure gradually restricted the base. Communist commanders turned to more conventional defensive warfare, suffered heavy losses and abandoned Jiangxi.

The Long March, 1934–1935

The Long March began in October 1934 as a military retreat from Jiangxi. Communist forces crossed difficult terrain and fought GMD troops as well as local forces while looking for a defensible base.

At the Zunyi Conference in January 1935, criticism of earlier military leadership increased Mao’s authority. The main force reached northern Shaanxi in October 1935, although other communist columns followed different routes and timescales.

The Long March was a devastating withdrawal, not an uninterrupted military triumph. Many participants died or became separated from the force. Its later importance came from survival: it preserved a communist core, raised Mao’s authority and gave the party a powerful story of endurance and sacrifice.

Yan’an and the position by 1936

After the Long March, the communists established their new centre in northern Shaanxi. The central leadership moved to Yan’an in January 1937. The remote location offered greater security and placed the party near areas threatened by Japanese expansion. From there, the communists rebuilt military strength, trained cadres and presented themselves as social revolutionaries as well as patriotic opponents of Japan.

The Xi’an Incident of December 1936 improved their position further. Commanders demanding stronger resistance to Japan detained Jiang Jieshi. Negotiation brought the crisis to an end and opened the way towards renewed cooperation against Japanese aggression.

Why communism had risen by 1936

Some interpretations stress structural rural poverty, while others place greater weight on GMD violence or Mao’s strategic ability. Hardship alone was not enough. Communist survival also depended on organization, armed protection and policies tailored to local conditions.

The Sino-Japanese War, 1937–1945

Full-scale war broke out after fighting near the Marco Polo Bridge in July 1937. Japan seized major cities and communications routes, including Shanghai and Nanjing. The Nationalist government first retreated to Wuhan, then to Chongqing. Japan held much of the coast and many urban areas, but it could not force either the Guomindang or the communists to surrender completely.

The Guomindang and the Chinese Communist Party formed a renewed united front, though their cooperation remained limited. Both fought Japan while keeping their forces and political influence intact for the post-war struggle they expected.

Political impact

The war changed the position of both parties. Jiang Jieshi kept international recognition as China’s national leader. After the wider Pacific War began in 1941, China became one of the principal Allied powers. Yet territorial losses, authoritarian rule and administrative corruption steadily weakened confidence in the GMD.

Japan created collaborationist administrations, including the regime led by Wang Jingwei at Nanjing from 1940. People collaborated for different reasons: opportunism, coercion, anti-communism or the belief that accommodation could limit destruction. Their collaboration deepened the fragmentation of Chinese politics.

The communists used resistance to Japan to strengthen their claim to national legitimacy. Their forces established base areas behind Japanese lines, combining guerrilla operations with local political organization. The united front continued formally, but armed clashes and mutual suspicion between communists and Nationalists did not disappear.

Military impact

The Nationalists led the largest conventional campaigns and suffered heavy battlefield losses, especially in the early defence of Shanghai and the later fighting for major cities. Jiang traded space for time, moving government institutions and industry inland. His forces stayed active, but weak supply systems, abuses connected to conscription and falling morale reduced their effectiveness.

Communist forces usually depended on guerrilla warfare, sabotage and political work in occupied rural areas. The Hundred Regiments Offensive of 1940 showed that they could coordinate larger operations, although it also triggered harsh Japanese countermeasures. Japanese campaigns against communist bases relied on collective punishments and the destruction of rural resources.

Both Chinese armies emerged exhausted, but the damage was uneven. The GMD had carried much of the conventional fighting and lost many of its best troops. By the war’s end, the communists had larger forces, broader rural networks and experience governing their base areas.

Social impact

Japanese occupation brought mass violence against civilians. The killings and sexual violence linked to the capture of Nanjing became the most notorious example. Atrocities, forced labour, reprisals and the destruction of villages also took place across occupied areas.

Millions were displaced. Bombing hit cities such as Chongqing, while the inland movement of the government, universities and factories disrupted families and local economies. In 1938, the Nationalists breached the Yellow River dikes. This slowed Japanese forces, but it also caused extensive flooding, displacement and loss of life.

Conscription and taxation placed heavy pressure on rural communities. Blockade, crop failures and administrative failures contributed to famine, especially in Henan in 1942–1943. These experiences damaged the relationship between many civilians and the Nationalist state.

Renewal of the Chinese Civil War

Japan surrendered in August 1945. Both Chinese parties hurried to accept Japanese surrenders and occupy strategic territory. Manchuria mattered particularly because it contained industry, railway networks and captured Japanese equipment. Soviet occupation initially complicated the contest, but communist forces later established a stronger position there.

American mediation under George Marshall failed to create a lasting coalition. Large-scale civil war resumed in 1946. The Nationalists initially controlled the main cities and railways and possessed a much larger conventional army. They even captured Yan’an in 1947. The communists avoided a decisive early defeat, gave up territory when necessary and gradually moved from guerrilla operations to conventional warfare.

Three major campaigns in 1948–1949 decided the conflict:

• Liaoshen Campaign: communist victory secured Manchuria.
• Huaihai Campaign: major Nationalist armies were destroyed in central-eastern China.
• Pingjin Campaign: communist forces took control of Beijing and northern China.

The communists crossed the Yangtze in 1949 and captured Nanjing and Shanghai. Mao proclaimed the People’s Republic of China in Beijing on 1 October 1949. Jiang Jieshi and the remaining ROC government withdrew to Taiwan.

Reasons for communist victory

One interpretation sees the communist victory mainly as the result of the war against Japan. Another points to Nationalist economic and political failures. A third emphasizes communist organization, leadership and military adaptation. The outcome came from their interaction: GMD weaknesses opened opportunities, but the communists still had to exploit those opportunities successfully.

Annexation and colonial government

Japan formally annexed Korea in August 1910. Korean sovereignty ended, and a Japanese governor-general took control of the peninsula with extensive administrative, police and military powers.

Early colonial rule was deeply coercive. Political organizations and the press faced restrictions, dissent was monitored, and Japanese officials controlled senior administrative positions. Between 1910 and 1918, the land survey introduced a more systematic property and taxation system. However, cultivators who could not prove ownership risked losing access to their land. Japanese companies and settlers acquired significant holdings.

The March First Movement began in 1919 with declarations and peaceful demonstrations calling for Korean independence. Japanese forces suppressed the movement violently. Korean nationalists then established the Provisional Government of the Republic of Korea in Shanghai, though it had no control inside Korea.

After 1919, the colonial authorities eased some of the most visible controls in a policy often known as “cultural rule”. Korean newspapers and cultural organizations gained limited freedom to operate. Japanese political supremacy remained, however, along with censorship and police surveillance.

Economic effects

Japanese rule linked Korea to the wider economy of the Japanese empire. Railways, ports, roads, communications and modern industries expanded. Agricultural output rose in some sectors, while heavy industry grew particularly quickly in northern Korea during the 1930s.

These changes mainly served imperial priorities. Korea supplied rice, minerals, industrial goods and labour to Japan’s wider empire. Japanese corporations enjoyed major advantages through access to capital and government support. Some Korean landowners and businesspeople benefited, but many tenant farmers faced high rents and insecure livelihoods. This encouraged migration to cities, Manchuria or Japan.

The economic legacy was mixed but unequal. Colonial rule built substantial infrastructure and industrial capacity, yet Japanese authorities and companies retained overwhelming control over profits and strategic decisions.

Social and cultural effects

Colonial education increased basic literacy and created a larger educated Korean population. Access remained unequal, though, and schools promoted loyalty to Japan. Japanese language and culture held a privileged position.

Assimilation intensified during the Sino-Japanese War. Koreans were pressured to worship at Shinto shrines, use Japanese in education and public life, and adopt Japanese-style names. Restrictions on Korean-language publication and teaching became increasingly severe.

These policies did not eliminate Korean identity. Instead, repression encouraged several forms of nationalism, including cultural preservation, Christian activism, socialism, armed resistance and overseas independence movements.

Korea and the Sino-Japanese War

From 1937, Korea became an increasingly important military and industrial base for Japan’s war in China and, later, the wider Pacific conflict. Mobilization grew more intense as Japan’s need for manpower increased.

Forced labour involved recruiting, directing or coercing Koreans into mines, factories, construction work and military-support roles across the Japanese empire. Wartime controls and pressure made the formal distinction between recruitment and compulsion increasingly weak.

Japan extended military conscription to Koreans during the final phase of the war, with implementation beginning in 1944. Koreans had also served earlier through volunteer systems and as civilian employees of the armed forces.

Comfort women were women and girls held in military sexual-service systems operated for the Japanese armed forces. Korean victims were recruited through coercion, deception, trafficking and the abuse of colonial authority. Debate over specific recruitment mechanisms does not change the central realities of exploitation, confinement and sexual violence.

Division at the 38th parallel

Japan’s surrender in August 1945 ended colonial rule, but it did not create a single independent Korean government. The United States and Soviet Union divided responsibility for accepting the Japanese surrender at the 38th parallel. Soviet forces occupied the north, while American forces occupied the south.

The great powers selected the line quickly and without Korean participation. It was meant to be an administrative arrangement rather than a permanent frontier. The developing Cold War, however, prevented agreement on a unified government.

Separate political systems took shape. The Republic of Korea was established in the south in August 1948 under Syngman Rhee. The Democratic People’s Republic of Korea followed in the north in September under Kim Il Sung. Both governments claimed authority over the entire peninsula. By 1950, political repression, violence along the border and incompatible state-building projects had transformed the 1945 division into a dangerous confrontation.

Assessing Japanese rule

One interpretation highlights infrastructure, industrialization and the development of modern administrative systems. Korean nationalist and post-colonial interpretations instead stress that these changes took place under coercive foreign rule and served Japanese needs. Economic development and colonial exploitation were not opposites: modernization occurred, but within an unequal system that denied Korean sovereignty and imposed severe political and human costs.

From Japanese colony to ROC administration

Taiwan had been under Japanese rule since 1895. After Japan surrendered in 1945, the island came under the administration of the Republic of China (ROC), led by the Guomindang. Jiang Jieshi appointed Chen Yi as chief executive.

Many Taiwanese welcomed the end of Japanese rule at first. Relations with the new authorities soon worsened, though. Some Taiwanese saw the officials arriving from the mainland as politically and culturally alien. Corruption in the administration, confiscation of Japanese assets, state monopolies, inflation and unemployment added to the resentment. Taiwanese people also found that they were excluded from much senior political authority.

The February 28 Incident

On 27 February 1947, government agents assaulted a Taiwanese cigarette seller in Taipei while enforcing the state tobacco monopoly. The confrontation caused a civilian death, and demonstrations followed the next day. Protests spread across the island. Local committees called for administrative reform and greater Taiwanese participation.

The authorities negotiated at first. In March, however, reinforcements from the mainland carried out widespread repression. Soldiers killed civilians and targeted local leaders, professionals, students and other members of the Taiwanese elite. The February 28 Incident, commonly called the 2–28 Incident, became a major source of hostility towards GMD rule.

The uprising was not one unified independence campaign. Participants wanted different changes, from the punishment of corrupt officials and provincial autonomy to broader political reform. Its suppression still transformed dissatisfaction with maladministration into a deeper struggle over who had the right to govern Taiwan.

Establishment of Jiang Jieshi’s rule

The communist victory on the mainland changed Taiwan’s position. In 1949, Jiang Jieshi, the ROC government, much of the remaining GMD military and a large population of mainland refugees relocated to the island. Taipei became the government’s seat, while the ROC continued to claim authority over all China.

The transfer brought experienced officials, soldiers, financial reserves and cultural institutions to Taiwan. It also deepened the divisions between mainland arrivals and the longer-established Taiwanese communities. Jiang rebuilt the GMD party-state on Taiwan and presented the island as a base for national recovery and the eventual reconquest of the mainland.

The Korean War began in June 1950 and strengthened the regime’s security. The United States deployed the Seventh Fleet to the Taiwan Strait, which reduced the immediate danger of a communist invasion.

Martial law

Martial law is government through emergency military powers that restrict ordinary civil and political rights. The GMD imposed it in Taiwan in May 1949, as it faced defeat on the mainland.

Political parties outside the approved system could not operate freely. The authorities restricted assembly, publication and public criticism. Security agencies monitored suspected opponents. The GMD kept representatives elected on the mainland and later held limited supplementary elections. These measures helped preserve its claim to represent the whole of China.

The government defended these controls as necessary for survival during civil war and communist infiltration. In practice, emergency rule also blocked open competition for power and silenced Taiwanese demands for political reform.

The White Terror

The White Terror was a campaign of political surveillance, arrest, imprisonment and execution carried out under GMD authoritarian rule. Its early phase accompanied the consolidation of the ROC on Taiwan after 1949.

Military tribunals and security agencies pursued suspected communists and underground networks. Repression also reached critics, intellectuals, students and advocates of Taiwanese autonomy. Accusations could be based on weak evidence or personal association. Fear and censorship discouraged public discussion of current politics and the 2–28 Incident.

The anti-communist security concerns were genuine. The GMD had just lost the mainland, and communist networks existed on Taiwan. This context explains the regime’s priorities, but it does not justify its broad use of punishment against peaceful dissent.

Beginnings of the Taiwanese independence movement

The independence movement grew out of several connected experiences. Japanese colonial rule had created social and institutional differences between Taiwan and the mainland. After 1945, ROC maladministration weakened the belief that a transfer to Chinese rule necessarily meant liberation. The repression of 1947 led some activists to conclude that autonomy within the ROC was unlikely to protect Taiwanese interests.

From 1948, Taiwanese exiles began forming organizations outside the island. These groups called for self-government or separation from China. Inside Taiwan, martial law made open advocacy extremely dangerous. As a result, the early movement was fragmented and driven largely from abroad.

Demands for administrative reform, provincial autonomy and full independence should be distinguished from one another. The positions overlapped, but they were not identical. By 1950, a clearly defined mass independence movement had not yet emerged. The political grievances and exile networks on which it would later build were already present.
