Key topic 2 · The triumph of Mao and the CCP, 1934–49

What a Grade 9 answer knows here. The CCP won the civil war largely because the Japanese war destroyed the Guomindang's armies and its currency while the Communists expanded in the countryside behind Japanese lines. The decisive cause of 1949 is an external invasion.

The 3 lessons

The Long March

How does a retreat that loses nine-tenths of an army become the foundation of a state? The fifth Extermination Campaign strangled the Jiangxi Soviet with blockhouses and blockade, and in October 1934 the Communist forces broke out to the west.

The war with Japan and the limitations of the Guomindang

Which army fought the Japanese, and which army grew because of them? Chiang's priority through the early 1930s was the destruction of the Communists rather than resistance to Japan, which had taken Manchuria in 1931.

The Civil War and the reasons for Communist victory

How does a government lose a war it began with more soldiers, more equipment and an American ally? In 1946 the Guomindang held the cities, had roughly three times the Communists' troop strength, possessed an air force and American-supplied equipment, and was the internationally recognised government.

The dates that earn marks in this key topic

Two from each lesson, in the order the topic is taught — each with the reason it is worth a mark, and the lesson that places it.

October 1934 — The Communists break out of Jiangxi after the fifth Extermination Campaign.: The March begins as an escape from a successful encirclement, not as a strategic initiative. (The Long March)
January 1935 — The Zunyi conference strengthens Mao's position in the leadership.: It is the March's decisive outcome, and it lasted more than forty years. (The Long March)
December 1936 — Chiang is seized at Xi'an and agrees to a united front against Japan.: It ends the priority of destroying the Communists and gives them a period of survival they might not otherwise have had. (The war with Japan and the limitations of the Guomindang)
1937–38 — The Guomindang loses Shanghai, Nanjing and Wuhan and its best divisions.: The conventional war destroyed the army and the tax base on which its authority rested. (The war with Japan and the limitations of the Guomindang)
1946 — Full-scale civil war resumes; the Guomindang holds the cities and has three times the troops.: It establishes the starting position that any explanation of the outcome has to overcome. (The Civil War and the reasons for Communist victory)
1948 — Hyperinflation and a failed currency reform ruin the urban middle class.: It is the decisive weakness and it is economic, not military. (The Civil War and the reasons for Communist victory)

The people to place

Mao Zedong — Strengthened his position in the leadership at Zunyi and directed strategy thereafter. (The Long March)
Zhu De — Commander of the Red Army during the March. (The Long March)
Zhang Guotao — Rival Communist leader whose forces separated from Mao's during the March. (The Long March)
Chiang Kai-shek — Led the Guomindang war effort from Chongqing after the loss of the coastal cities. (The war with Japan and the limitations of the Guomindang)
Zhang Xueliang — Commander who seized Chiang at Xi'an in December 1936 to force resistance to Japan. (The war with Japan and the limitations of the Guomindang)
Lin Biao — Communist commander whose Manchurian campaigns preceded the decisive battles. (The Civil War and the reasons for Communist victory)

What students say — and what is actually the case

“The Long March was a military success.” — The party abandoned its base and lost the great majority of its forces. Its importance is political and strategic — the leadership change at Zunyi and the base at Yan'an — rather than military. (The Long March)
“The Communists did most of the fighting against Japan.” — Guomindang forces bore the great weight of the conventional war and lost their best divisions doing it. The Communists fought a guerrilla war behind Japanese lines that cost them far less and gained them far more. (The war with Japan and the limitations of the Guomindang)
“The Communists won because they had more soldiers.” — They began with roughly a third of the Guomindang's strength. The balance changed through capture, defection and recruitment during the war itself. (The Civil War and the reasons for Communist victory)
