Lesson 3: Revolutionary Chaos in China

In this Grade 5 World History and Geography lesson from Chapter 29, students explore the power struggle between China's Nationalist Party under Chiang Kai-shek and the Chinese Communist Party following the 1923 Nationalist-Communist alliance. Students learn how the Shanghai Massacre of 1927 ended that alliance and drove Mao Zedong and Communist forces into rural Jiangxi Province, where they began organizing peasant-based resistance using guerrilla tactics. The lesson examines how competing visions for China's future — including redistribution of wealth and Confucian values — fueled revolutionary chaos during the 1920s and 1930s.

Section 1

📘 Revolutionary Chaos in China

Lesson Focus

Explore how China's Nationalist and Communist parties allied against imperialists, but their rivalry soon plunged the nation into civil war, setting the stage for revolution.

People to Know

Chiang Kai-shek, Mao Zedong

Learning Objectives

  • Trace the shifting alliance between the Nationalists and Communists, from early cooperation to the outbreak of civil war.
  • Analyze the characteristics of the “New China” Chiang Kai-shek attempted to build, including his social and economic policies.

Section 2

Nationalists and Communists Unite Against Imperialists

To drive out imperialists and warlords, Sun Yat-sen’s Nationalist Party and the new Chinese Communist Party (CCP) formed an alliance in 1923.

They launched the Northern Expedition in 1926, successfully taking control of southern China and major ports.

This cooperation, however, masked deep suspicions between the two groups. Pay special attention to how this fragile alliance eventually set the stage for a brutal civil war once their common goals were partially achieved.

Section 3

Chiang Kai-shek Betrays the Communists

Following the previous summary, tensions rose after Sun Yat-sen's death, and his successor, Chiang Kai-shek, secretly planned to eliminate his rivals.

In April 1927, he ordered the Shanghai Massacre, killing thousands of Communists and their supporters.

As a result, the Nationalist-Communist alliance ceased to exist. The Communists were forced into hiding, and Chiang established a new Chinese republic at Nanjing, determined to destroy the CCP.

Section 4

Mao Zedong’s Army Escapes Annihilation

Forced into hiding, a young Mao Zedong built a Communist base in Jiangxi Province, relying on peasant support and guerrilla tactics.

In 1934, Chiang's army surrounded the base, forcing Mao’s People’s Liberation Army (PLA) to begin The Long March—a brutal 6,000-mile retreat.

Note that while the army suffered massive losses, the survivors reached safety in northern China, and Mao Zedong emerged as the sole leader of the CCP.

Section 5

Chiang Kai-shek Attempts to Build a New China

While fighting the Communists, Chiang Kai-shek tried to build a new China by introducing modern Western ideas into a conservative culture.

He launched the New Life Movement to promote traditional Confucian virtues like duty and honor, while also building new roads and factories.

However, the movement largely failed because Confucian ideas had been discredited by China’s recent decline, and the government faced overwhelming problems like Japanese aggression and the Great Depression.

Section 6

Chiang's Policies Create a Deep Class Divide

Because Chiang’s government drew support from the urban elite and wealthy landowners, it failed to help the vast peasant population.

It suppressed opposition, censored free expression, and refused to push for a redistribution of wealth that would benefit the poor.

This created a deep class divide. While cities modernized, the rural majority remained impoverished and alienated, which undermined Chiang's authority and fueled support for the Communists who promised radical change.
