Why did the Chinese Communist Party reinterpret Sun Yat-sen's ideology?

The Chinese Communist Party, led by Mao Zedong, reinterpreted Sun Yat-sen's original political ideology into the New Three Principles of the People to align with revolutionary goals during the First United Front. This reinterpretation linked Sun's principles directly to the Three Great Policies of allying with the Soviet Union, cooperating with the CCP, and supporting workers and peasants. High-ranking Kuomintang officials, including Chiang Kai-shek, explicitly rejected this division into old and new versions.

What we know

• The New Three Principles of the People represent a reinterpretation of Sun Yat-sen's ideology by the Chinese Communist Party under Mao Zedong. [1, 2]
• The reinterpretation was introduced to distinguish the revolutionary theory of the First United Front period from Sun's original principles prior to the Northern Expedition. [2]
• The CCP's revised doctrine integrated the Three Great Policies of alliance with Russia, alliance with the CCP, and support for workers and peasants. [2]
• Kuomintang leaders such as Chiang Kai-shek explicitly opposed the division of the Three Principles into old and new versions. [2]

Still open

• Whether Sun Yat-sen's original intent during the First National Congress fully endorsed the specific socialist mechanisms later emphasized by the CCP remains a point of ideological contention with the Kuomintang.
